[00:00] <Darkside> how much is required to make it work on 2m vs 70cm?
[00:00] <Randomskk> Zuph: reference schematic, but as far as I'm aware they don't provide reference hardware layout?
[00:00] <Zuph> Randomskk: I found a picture of some expensive reference hardware.
[00:00] <Randomskk> expensive doesn't always imply decent. I'd be seriously concerned about that.
[00:00] <Zuph> I understand.
[00:00] <Randomskk> (also by snaking it up you can totally make the board shorter :P)
[00:01] <Darkside> Zuph: so do you have the values to make it work at 2m?
[00:01] <Zuph> Oh, yeah. I was just worried about trace inductance.
[00:01] <Randomskk> in particular, http://www.maxim-ic.com/app-notes/index.mvp/id/4636 gives a few good pointers, and
[00:02] <Zuph> I don't have access to a network analyzer or spectrum analyzer or anything like that, so my gold standard will be "What does it look like on the waterfall."
[00:02] <Zuph> Darkside: HAve to change filter and PLL components, and use different internal register values for 2M, 70CM and 33CM.
[00:02] <Darkside> ok
[00:02] <Darkside> thats not too bad
[00:02] <Darkside> do you have values for the 3 bands?
[00:02] <Darkside> and what kind of bandwidth can you get out of each configuration?
[00:03] <Zuph> Darkside: Not handy. I used the TI software to calculate the values, then did a quick sanity check on a few numbers.
[00:03] <Darkside> cool
[00:03] <Randomskk> Zuph: https://randomskk.net/u/adf.png
[00:04] <Zuph> This should be able to do 2FSK (RTTY, really) from 50 BPS - 1000 BPS, if TI's calculator is sane. I double checked the numbers for the low end, but not the high end.
[00:04] <Darkside> cool
[00:04] <Darkside> as long as it can do 300 baud i'm happy
[00:04] <Darkside> fun thing it it could also do MFSK-4
[00:05] <Darkside> which has FEC built in
[00:05] <Zuph> I didn't think the 7012 could do MFSK.
[00:05] <Randomskk> it can
[00:05] <Darkside> yeah it can
[00:05] <Randomskk> but like
[00:05] <Randomskk> the minimum shift depends on operating frequency
[00:05] <Darkside> they use it for DSTAR
[00:05] <Randomskk> and is on the order of 150Hz between frequencies
[00:05] <Randomskk> or 300Hz or so. at 434MHz tx, anyway
[00:05] <Zuph> ah
[00:05] <Darkside> Zuph: they use the ADF7012 in the dstar dongle APs
[00:06] <Zuph> I didn't know that.
[00:06] <Darkside> and DSTAR uses FSK4
[00:07] <Zuph> Randomskk: How did that filter layout work out?
[00:07] <Randomskk> Zuph: it seems to work nicely, but I haven't got anything handy that can do 434MHz to check
[00:08] <Randomskk> waterfall is pretty clean but I don't have any screenshots
[00:08] <Zuph> Honestly, if this spews RF all over the spectrum, I'm not too concerned.
[00:08] <Randomskk> heh
[00:08] <Darkside> Zuph: you might not be
[00:09] <Zuph> Transmitting in the ham bands at 25 mW, even the most curmudgeonly repeater denizen won't be too inconvenienced.
[00:09] <Darkside> yeah
[00:09] <Zuph> Slap my call sign on the RTTY, and the FCC officially doesn't care.
[00:10] <Randomskk> you guys and your ability to tx under license >_>
[00:10] <Randomskk> also we get hams on repeaters getting pissed off at 10mW tx :(
[00:10] <Randomskk> silly hams should really do ctcss codes
[00:10] <Darkside> they shouldn't have to
[00:11] <Zuph> hah
[00:11] <Darkside> serious
[00:11] <Zuph> All the repeaters around here have CTCSS
[00:11] <Darkside> i doubt 10mw of rtty will break the squelch on a FM repeater
[00:12] <Zuph> Okay, I'm seriously not seeing MFSK under the ADF7012, can someone slap me around?
[00:12] <Zuph> I see it under the ADF7021
[00:12] <Darkside> its FSK-4 or something
[00:12] <Darkside> oh
[00:12] <Darkside> hmmmm
[00:12] <Darkside> maybe its the 7021 i'm thinking of
[00:12] <Randomskk> oh
[00:12] <NigeyS> http://www.ustream.tv/channel/nigeyuk ...... hamstercam
[00:12] <Darkside> is the 7012 a transceiver?
[00:12] <Randomskk> no
[00:12] <Zuph> no
[00:12] <Darkside> ok
[00:12] <Darkside> then its the 7021 :P
[00:12] <Darkside> my bad
[00:12] <Zuph> heh
[00:12] <Zuph> :-p
[00:13] <Randomskk> I think I was thinking of programming registers to do it
[00:13] <Zuph> My goal is to make these light enough to do some superpressure testing.
[00:13] <Darkside> meh we already have that :P
[00:13] <Darkside> i've got a working 47g payload
[00:13] <Darkside> runs of 2 AAAs
[00:13] <Zuph> This should last 16 hours on a single AA battery.

[00:14] <Darkside> mmm should be able to run mine off 1xAA...

[00:15] <Darkside> oh?
[00:15] <Darkside> i've been looking at some TI ones
[00:15] <Darkside> they can handle quite a bit of current too
[00:15] <Zuph> One external inductor, operation down to .35 volts, startup at .65v.
[00:15] <Darkside> i've been wanting to make a dual-rail switchmode supply
[00:15] <Darkside> hmm
[00:15] <Darkside> what current rating for the Mosfet though
[00:15] <Zuph> Up to 100mA out with 1.2vin
[00:16] <Darkside> bah
[00:16] <Zuph> 350 mA out with 2.4 vin
[00:16] <Darkside> not enough for what i want
[00:16] <Zuph> Fair enough.
[00:16] <Darkside> we'll need burst output current of 200mA or so with very low input voltage
[00:16] <Darkside> (for APRS - the HX1 transmitters)
[00:16] <Zuph> I think I'll leave the filter as is, screw it if it sucks, only out $20 for the PCBs.

[00:42] <Zuph> KiCad is really growing on me.
[00:43] <Darkside> i need to take a look at that sometime
[00:43] <Randomskk> <3 kicad
[00:43] <Darkside> i'm still sticking with altium designer though
[00:43] <Randomskk> Zuph: have you started playing with hierarchial sheets in the schematic editor?
[00:43] <Randomskk> so so neat
[00:43] <Darkside> Randomskk: welcome to 10 years ago
[00:43] <Darkside> :P
[00:43] <Randomskk> each child sheet becomes basically a component in the parent sheet
[00:44] <Randomskk> Darkside: * points to eagle
[00:44] <Darkside> i've been doing heirachal components for ages
[00:44] <Darkside> sheets*
[00:44] <Zuph> Randomskk: Yes siree!
[00:44] <Randomskk> also kicad's been doing that for about as long anyway
[00:44] <Darkside> yeah
[00:44] <Darkside> all of them to
[00:44] <Darkside> do*
[00:44] <Randomskk> does eagle?
[00:44] <Randomskk> well, certainly not for free
[00:44] <Randomskk> but I can't even remember if the paid one does hierarchial sheets
[00:44] <Zuph> I mean, if I had $3000, I'd get a copy of Altium, but for open sourc-ey, free stuff, KiCad beats the pants of eagle
[00:45] <Darkside> Zuph: are you a student?
[00:45] <Randomskk> also by making things in altium it's very hard for anyone else to do anything with them
[00:45] <Randomskk> unless they also have altium, of course
[00:45] <Darkside> altium do student licenses for $100/year
[00:45] <Zuph> Darkside: Not any more!
[00:45] <Darkside> ahh
[00:45] <Randomskk> the PCB world really needs an open standard for libraries, schematics and PCB layouts
[00:45] <Randomskk> ha ha ha
[00:45] <Zuph> I miss school :(
[00:45] <Randomskk> god that'd be nice to have.
[00:46] <Randomskk> libraries could just exist for every part
[00:46] <Randomskk> you could play with anyone's schematic
[00:46] <Zuph> I like being able to open source my stuff, so it's either kicad or eagle.
[00:46] <Darkside> i alternate between my uni's license and a cracked license
[00:46] <Darkside> i still prefer altium designer as it's just so damn powerful...
[00:47] <Darkside> and once i get into the industry its what i'll be using
[00:47] <NigeyS> they all confuse me, but im dense, so pls ignore :)
[00:47] <Darkside> altium designer is very popular in australia
[00:47] <Zuph> Even though they went and took all those jobs to shanhai? :-p
[00:48] <Zuph> *Shanghai
[00:48] <Zuph> I wish I did pcb design work in industry :(
[00:48] <Darkside> heh
[00:49] <Darkside> i got offered a position doing just that
[00:49] <Darkside> i turned it down to do a PhD
[00:49] <Darkside> and atm i'm doing pcb design for the PhD :P
[00:49] <Darkside> making a USB software defined radio
[00:52] <Zuph> neat
[00:52] <Darkside> only 48KHz bandwidth
[00:52] <Darkside> thats because i can't find a direct to usb audio codec that does 96KHz or up
[00:52] <Darkside> i could use an I2S audio codec and a microcontroller to do it, but that ups the cost
[00:53] <Randomskk> why are you using usb audio?
[00:53] <Randomskk> ah, I guess
[00:53] <Darkside> Randomskk: because many netbooks and things don;t have stereo audio inputs
[00:53] <Randomskk> I'd have thought usb bulk transfer to just shift data in
[00:53] <Darkside> and usb audio is supported on basically everything

[00:53] <Randomskk> ....really, though? almost all have a microphone input. but I meant more why use the usb audio protocol vs bulk transfer
[00:53] <Zuph> I regret not taking to opportunity to continue straight into a PhD, but I don't regret the money in industry :-p
[00:53] <Randomskk> which is about as supported
[00:53] <Randomskk> fair enough
[00:53] <Randomskk> Zuph: what do you do?
[00:54] <Darkside> Randomskk: usb audio protocol so it'll work with basically any program that supports audio
[00:54] <Darkside> matlab, spectravue, sdr-radio
[00:54] <Darkside> whatever
[00:54] <Zuph> Embedded Software Engineering for a tiny arm within a massive, soulless fortune 100 company.
[00:55] <Darkside> lol
[00:55] <Randomskk> Darkside: yea, fair enough.
[00:55] <Randomskk> Zuph: hehe cool
[00:55] <Randomskk> well I say "cool", I dunno, is it?
[00:56] <Darkside> Randomskk: i'll probably be using matlab for some processing
[00:56] <Randomskk> Darkside: I would say boo hiss, but matlab is pretty useful really
[00:56] <Randomskk> do consider numpy/scipy :P
[00:56] <Darkside> and we'll also be using the board as a third year RF practical, so students will be building a LO and demodulating signals in matlab
[00:56] <Randomskk> hah
[00:56] <Darkside> Randomskk: well i prefer gnuradio :P
[00:57] <Randomskk> that'd be kinda cool
[00:57] <Randomskk> I just did a third year practical with a superhet radio
[00:57] <Darkside> yeah, the idea is we make a RF practical that is actually really interesting
[00:57] <Randomskk> where we measured the LO and bla bla bla
[00:57] <Darkside> the current prac is a direct conversion receiver
[00:57] <Randomskk> doing it in matlab would be cool
[00:57] <Darkside> but we want to make it a SDR
[00:57] <Zuph> Randomskk: I'd rather be in academia or working at a small shop, but there aren't many small shops in town, and I'm not going to be leaving town for at least a few years.
[00:57] <Darkside> so yeah, we get the students to design and built a LO, and probably some filters and a preamp
[00:57] <Darkside> and at the end of the prac they can choose to take the entire thing home with them
[00:57] <Randomskk> oh nice
[00:58] <Darkside> and we essentially send them away with an incredibly versatile software defined radio
[00:58] <Randomskk> sounds like your practicals are a lot more interesting than ours
[00:58] <Darkside> they will be
[00:58] <Randomskk> that's cool
[00:58] <Zuph> Money is nice, though. I have a savings account and health insurance for the first time :-p
[00:58] <Darkside> i'm really looking forward to this
[00:58] <Darkside> it'll also be great to being people into ham radio
[00:58] <Randomskk> Darkside: that sounds very cool
[00:58] <Darkside> bring*
[00:58] <Zuph> Darkside: That sounds loads more fun than my RF course.
[00:58] <Randomskk> Zuph: hehe yea, fair enough really. plus the experience can't hurt for when you do leave town
[00:58] <Darkside> i'm probably going to be writing all the prac notes for this..
[00:58] <Randomskk> I recently realised that our practicals are not designed to be fun, though
[00:58] <Darkside> since it's effectively my baby
[00:58] <Randomskk> in fact my course is not designed to be fun to someone who enjoys engineering
[00:59] <Darkside> lol
[00:59] <Zuph> Randomskk: True enough. PhD programs are getting better about not looking down on those with industry experience.
[00:59] <Randomskk> it's designed to be gruelling and challenging and tedious and select for perseverance, as far as I can tell
[00:59] <Darkside> i don't think designing the LO for this prac will be easy
[00:59] <Darkside> as its going to need to be a 2xLO, as its a quadrature downconverter
[00:59] <Randomskk> meh, hand hold people through hard bits
[00:59] <Darkside> yeah
[01:00] <Darkside> i'm hoping i can sort out a design thats tunable over a wide rance
[01:00] <Darkside> range*
[01:00] <Darkside> we can also swap it out with a DDR
[01:00] <Darkside> DDS*
[01:00] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) left irc: Ping timeout: 248 seconds
[01:00] <Darkside> anyway, while we'll probably be looking at AM broadcast stations in this prac, the board is capable of going from about 500KHz up to 700MHz
[01:01] <Darkside> with only 48KHz bandwidth your optiosn are limited, but its fine for ham radio stuff, and other narrowband signals
[01:01] <Randomskk> that's more than a channel at 70cm so most ISM devices should in theory fit in it
[01:02] <Darkside> yep
[01:02] <Darkside> but yeah, getting a 2xLO for those frequenices will be painful
[01:02] <Darkside> you'd need a 900MHZ LO
[01:02] <Randomskk> ouch.
[01:02] <Darkside> its doable
[01:02] <Darkside> but painful
[01:02] <Darkside> thats why we're targeting AM broadcast for the prac
[01:03] <Randomskk> colpitts and a good fT I guess, but yea
[01:03] <Darkside> i was thinking a PLL based thing
[01:03] <Randomskk> PLLs are much harder to design
[01:04] <SpeedEvil> Anderson alternator.
[01:04] <SpeedEvil> alexanderson, even.
[01:05] <Darkside> the mixer wants -15dBm to 0dBm 2xLO power
[01:05] <Darkside> thats about what you get directly from a DDS, which is nice
[01:06] <Darkside> we'll probably be using bench sig-gens at uni for testing
[01:06] <Darkside> so thats no problem

[09:18] <fsphil> what I can't say is how well it handles the elements - mine is kept indoors until I need it
[09:18] <jcoxon> fsphil, yagi?
[09:19] <eroomde> i need omni directional
[09:19] <eroomde> as i want to be able to remotely set a listening station going
[09:19] <eroomde> was going to try and discone recommended by M0JCU
[09:19] <eroomde> but also Upu's colinear seems to do a very nice job
[09:19] <eroomde> incidently someone really should fly a colinear on a balloon
[09:20] <eroomde> they seem ideal
[09:20] <eroomde> especially for long distance floaters
[09:20] NigelMoby (~nigel@ left irc: Ping timeout: 256 seconds
[09:20] <gonzo_> if you have a rough idea of the trajectory of a hab, you can choose a colinear with the correct gain
[09:20] <gonzo_> no point having lots of gain, only to result in a null overhead
[09:21] <fsphil> jcoxon, yea
[09:22] <fsphil> eroomde, I mis-read that as you *have* a rotator
[09:23] <fsphil> in that case definitely the watson, seems the best all-round omni
[09:23] <gonzo_> I have used collinears for LEO satellites. And for the usual orbits, the difference between coming over the horison and being above is 10dB. So a 10dB colinear is about right (ok, not quite that simple, but a good starting point)
[09:24] <eroomde> gonzo_: not convinced
[09:24] <gonzo_> watson are def well built, whioch is soooooo important for outdoor kit
[09:24] <eroomde> the null overhead is also where the balloon is at most about 30km away
[09:24] <jcoxon> i guess the being on the roof is key
[09:24] <jcoxon> the additional clearance
[09:24] <eroomde> and we know that we can receive signals from 700km away
[09:25] <fsphil> mine is about 4m above the roof
[09:25] <gonzo_> Agree, I was talking about satellites. You'd need to profule the ant pattern for balloons
[09:25] <eroomde> and (700/30)^2 = 530
[09:25] <gonzo_> and depends where you are from the launch site.
[09:25] <fsphil> pretty much the tallest thing around... which always makes me nervous during a thunderstorm ;)
[09:26] <fsphil> I tracked hadie:3 for the entire flight from my home station, it varied from about 8-30km away
[09:26] <fsphil> the angle was pretty high
[09:26] <eroomde> and 530 is about 27dB difference
[09:27] <eroomde> so I think that the difference in gain by putting more energy out the the horizon is more than offset by the difference in power received between overhead and 700km away
[09:27] <gonzo_> if you are reaasonably close to the launch site, then why not mount an az/el rotator on a temp ground mount. Back of car, or tripod
[09:28] <eroomde> i'm not
[09:28] <jcoxon> gonzo_, i doubt its that useful anyway
[09:28] <eroomde> but when I am, we do
[09:28] <fsphil> a whip at the launch site is all you need :)
[09:28] <gonzo_> given the probable path, you're prob right. My experience is all with satellite
[09:29] <fsphil> I'm not sure higher gain on the payload is all that useful - the earth will get in the way before the signal fades enough to be a problem, even with a colinear
[09:30] <eroomde> well, there's refraction, but also it really is all about the last few km extra
[09:30] <eroomde> or that slightly lower last reported position during descent
[09:30] <gonzo_> gain on a uk HAB is prob no advantage, given the pittiful eirp limits
[09:30] <fsphil> you also make it more susceptible to fading as the payload tilts
[09:32] <eroomde> if people would just design parachute systems properly, they wouldn't tilt...
[09:32] <eroomde> a different conversation tho
[09:33] <jcoxon> eroomde, haha
[09:33] <jcoxon> right all thats left to do is construct my antenna...
[09:33] <eroomde> colinear....

[10:21] <Darkside> trackuino: i'll try and get our changes to your code up tonight
[10:21] <trackuino> about what time?
[10:21] <Darkside> approx 0UTC or so
[10:21] <trackuino> seirously? night flight?
[10:21] <Darkside> we're +95
[10:21] <Darkside> +9.5
[10:21] <Darkside> sorry, +10.5 atm
[10:21] <trackuino> ah ok, thought you were in the UK
[10:22] <Darkside> hmm, in that case its going to be more like 22:30UTC saturday
[10:22] <jcoxon> trackuino, whats wrong with a nightflight :-)
[10:22] <Darkside> nah
[10:22] <Darkside> trackuino: the changes were to bring the sent packets closer to the aprs spec. we're also working on compressed packets
[10:22] <trackuino> flight is okay at night, recovery not so :)
[10:23] <Darkside> they aren't planning on recovering it :P
[10:23] <trackuino> ok, will try to watch on aprs.fi
[10:23] <Darkside> trackuino: ooh yeah
[10:23] <Darkside> gotta show you the APRS tracker
[10:23] <Darkside> http://rfhead.net/wp-content/uploads/2011/09/MicroAPRS.jpg
[10:24] <Darkside> thats basically it
[10:24] <trackuino> I'm really interested in those changes. I'll definitely merge them in my code base
[10:24] <trackuino> Wow
[10:24] <Darkside> HX1 on the back
[10:24] <trackuino> and the GPS is built in
[10:24] <Darkside> well, in that pic its a TX1h, but the actual aprs one has a HX1
[10:24] <Darkside> yep
[10:25] NigelMoby (~nigel@ joined #highaltitude.
[10:25] <Darkside> atm it needs externally regulated 5v going into it
[10:25] <Darkside> we've got a little boost converter glued to the back of a 2xAA holder
[10:25] <Darkside> lasts for about a day with a 30 second transmit interval
[10:25] <trackuino> impressive :o
[10:25] <Darkside> will last far longer once we can get the gps into power save mode properly
[10:26] <Darkside> trackuino: it was soooo easy to get your code working on it
[10:26] <Darkside> turns out i'd used the same pin for the TXD line :P
[10:26] <trackuino> is that a copernicus gps?
[10:26] <Darkside> nope, ublox
[10:26] <Darkside> on that board a ublox 5, on the one we're flying a ublox 6
[10:26] <trackuino> ublox. works over 18 Km, i assume
[10:26] <Darkside> yup
[10:27] <trackuino> do you have schematics and pcb online somewhere? i'd love to mention your work
[10:27] <Darkside> sadly no, not atm
[10:27] <Darkside> the design of that board won't be released
[10:27] AndChat| (~nigel@cpc5-cdif13-2-0-cust232.5-1.cable.virginmedia.com) joined #highaltitude.
[10:28] <trackuino> ok, understood
[10:28] <Darkside> mainly because its really light
[10:28] <Darkside> as in, fly-without-notam light
[10:28] <jcoxon> Darkside, perhaps a generic design
[10:28] <jcoxon> or concept schematic
[10:28] <Darkside> jcoxon: oh, i could release the schematic fine
[10:29] <trackuino> yeah, more like fly-with-a-party-balloon light :)
[10:29] <Darkside> pcb... i'd rather not
[10:29] <Darkside> trackuino: yeah
[10:29] <Darkside> <50g with batteries
[10:29] <Darkside> we'd rather not have anyone else in australia try and do a launch with one at the moment
[10:29] <Darkside> it only takes one group to screw up...
[10:29] NigelMoby (~nigel@ left irc: Ping timeout: 252 seconds
[10:30] <Darkside> anyway, that board has problems
[10:30] <Darkside> requiring regulated 5v is one of them
[10:30] <Darkside> next version will have a dual rail switchmode supply
[10:30] <trackuino> can't you use a LDO reg on-board?
[10:30] <Darkside> well everything else runs from 3.3v
[10:30] <trackuino> two LDO regs...
[10:30] <Darkside> yeah...
[10:30] <Darkside> nah
[10:30] <Darkside> means more wasted power
[10:31] <Darkside> we're working on a boost/buck regulator, one that can take effectively anything from 1v to 10v or so and give 5v and 3.3v rails
[10:32] <trackuino> yeah... powering from 2xAA makes it super light
[10:32] <Darkside> yup
[10:32] <eroomde> even more so with 1!
[10:33] <eroomde> i think we did some sums saying you could get a balloon tracker to about 60mW average consumption
[10:33] <Darkside> if we can get this ublox into the proper power save mode it'll be good
[10:33] <eroomde> and an energizer lithium ultimate has nominally 1.5Wh energy
[10:33] <trackuino> that looks about right... assuming the gps can be put to sleep
[10:33] <Darkside> yeah
[10:33] <eroomde> so that's a lot of hours just from 1 AA cell
[10:33] <Darkside> we were actually thinking of storing the ephemrtis and almanac in a spi flash
[10:34] <Darkside> and cutting power to the gps
[10:34] <eroomde> that's a good idea
[10:34] <eroomde> tho can you not jsut have battery backup?
[10:34] <Darkside> then turning it back on, feeding it the ephemeris and almanac so it'll get lock faster
[10:34] <Darkside> eroomde: of course
[10:34] <Darkside> probably easier :P
[10:34] <trackuino> yeah :)
[10:34] <Darkside> we want to do the storage of ephemeris and stuff anyway tho
[10:34] <eroomde> it just takes nW to keep the ram happy
[10:34] <Darkside> could be useful
[10:34] <eroomde> yeah it would be interesting
[10:34] <Darkside> means it'll gain lock faster on boot
[10:34] <jcoxon> the ublox 6 can intheory do tracking at 13mW
[10:34] <jcoxon> oops
[10:34] <jcoxon> i mean 13mA
[10:35] <eroomde> 22mW
[10:35] <Darkside> mm

[10:35] <Darkside> yeah

[10:37] <Darkside> ok
[10:37] <trackuino> do you have experience in 433 MHz?
[10:37] <Darkside> yeah, we normally fly RTTY
[10:38] <trackuino> is any of the radiometrix radios good at tracking from high altitude?
[10:38] <Darkside> we're flying RTTY this time too, since we're not 100% sure of the ublox 6 GPS
[10:38] <Darkside> trackuino: yeah, all of them lol
[10:38] <Darkside> we normally fly the NTX2 transmitters
[10:38] <Darkside> 434.650 or 434.075MHz
[10:38] <Darkside> UK guys use 10mW versions, we use 25mW
[10:38] <trackuino> yeah well I saw they're just 10mW or so and I was not sure they're powerful enough...
[10:38] <Darkside> have had them be receiverd and demodulated from hundreds and hundred of km away
[10:39] <trackuino> really?
[10:39] <Darkside> yeah
[10:39] <Darkside> its RTTY
[10:39] <trackuino> well you use RTTY
[10:39] <Darkside> narrow bandwidth
[10:39] <trackuino> that's right
[10:39] <trackuino> VERY much so
[10:39] <Darkside> works a carm
[10:39] <Darkside> charm*
[10:39] <Darkside> its our standard tracking system, same for most people in this channel
[10:39] <trackuino> what do you think if I were to use AFSK on them?
[10:39] <Darkside> means the power is more spread out
[10:39] <trackuino> makes the bandwidth wider...
[10:39] <trackuino> yes
[10:39] <Darkside> if you're just tracking, RTTY is fine
[10:40] <trackuino> I'm not sure about the range with AFSK.
[10:40] <jcoxon> current record is 775km
[10:40] <Darkside> we use 300 baud
[10:40] <trackuino> I hate the fact that you have to retune due to freq drift
[10:40] <Darkside> trackuino: given the drift we've seen you'd have to retune with FM too
[10:40] <Darkside> we've seem them drift by up to 15KHz
[10:40] <trackuino> oh
[10:41] <trackuino> it doesn't look that bad in the 144 MHz versions
[10:41] <Darkside> trackuino: if you don't want to retune, then use the 100mW VHF Modules
[10:41] <Darkside> the TX1H's
[10:41] <Darkside> they don't drift more than a few hundred hz
[10:41] <trackuino> can you do anything higher than 300 bauds with rtty?
[10:41] <Darkside> of course you can!
[10:41] <trackuino> i'm thinking of sending images
[10:41] <Darkside> SSDV
[10:41] <Darkside> fsphil does that
[10:42] <Darkside> he uses 300 baud, but TimZaman has done 600 baud
[10:42] <trackuino> yeah i was reading the SSDV page
[10:42] <Darkside> i'm planning on doing 600 baud too
[10:42] <Darkside> 1200 baud is possible, but you need a large shift
[10:42] <NigeyS> has anyone tried 1200 yet Darkside ?
[10:42] <Darkside> NigeyS: tim has i think
[10:42] <Darkside> it didn't work so well
[10:42] <NigeyS> oo
[10:42] <Darkside> fldigi doesn't handle it nicely
[10:42] <Darkside> trackuino: we're considering sending SSDV via APRS
[10:42] <NigeyS> ah dam, would be nice if it worked mind
[10:42] <trackuino> is there any problem shifting through the whole range 0 .. 5 V
[10:42] <Darkside> but we'd have to inform the network operators first :P
[10:43] <Darkside> trackuino: thats a huge shift then
[10:43] <Darkside> trackuino: that'd be about a 10KHz output shift
[10:43] <trackuino> right
[10:43] <Darkside> no normal receiver will handle that
[10:44] <trackuino> what are cheap SSB receivers? i assume the puxings are only FM
[10:44] <Darkside> yeah
[10:44] <Darkside> dunno about cheap ones...
[10:44] <trackuino> damn
[10:44] <Darkside> tbh if you have a usable APRS network, you may as well stick with APRS
[10:44] <Darkside> it works fine
[10:44] <NigeyS> ssb & cheap tend not to go in the same sentence :(
[10:44] <Darkside> yeah
[10:44] <trackuino> i want to get into 433 but not at the price of a kidney

[10:45] <Darkside> receivers
[10:45] <trackuino> yeah, but no imagery on APRS.
[10:45] <griffonbot> Received email: Solar Balloonman "[UKHAS] Re: James May, Man Lab."
[10:45] <Darkside> trackuino: yeah you might not be able to
[10:45] <Darkside> :P
[10:45] <Darkside> we can probably get away with it here
[10:45] <russss> surely it's only a matter of time before we get cheap Chinese handhelds with reject mobile phone hardware doing SDR
[10:45] <Darkside> trackuino: why not try the 100mW modules with AFSK
[10:45] <Darkside> i'm sure they'd be high enough power
[10:45] <Darkside> and they don't drift
[10:46] <Darkside> you could just run AX25 on it
[10:46] <trackuino> which 100 mW module? radiometrix?
[10:46] <Darkside> yeah
[10:46] <trackuino> i defenitely want to give it a try
[10:46] <Darkside> the TX1H modules
[10:46] <Darkside> theres a nice range of frequencies available
[10:46] <Darkside> trackuino: where are you baseD?
[10:46] <Darkside> US?
[10:46] <trackuino> can decode with a puxing... shouldn't need retuning...
[10:46] <trackuino> Spain
[10:47] <Darkside> theres 144.390MHZ 100mW modules
[10:47] <Darkside> could just use one of those
[10:47] <Darkside> europe APRS is 144.8MHZ, right?
[10:47] <trackuino> yep
[10:47] <Darkside> there ya go
[10:47] <Darkside> i did my first APRS testing on the 144.39MHZ modules
[10:47] <trackuino> do you think i can hook up two radiometrix radios to the same antenna?
[10:47] <Darkside> not without a diplexer
[10:47] <trackuino> ie. will one radio stay "high impedance" while the other transmits?
[10:47] <trackuino> ok
[10:48] <Darkside> and making a small one to split 144.390 and 144.8MHz will be... challenging
[10:48] <Darkside> to say the least
[10:48] <trackuino> even if they're not transmitting at the SAME time?
[10:49] <Darkside> i wouldn't do it
[10:49] <trackuino> ok
[10:49] <Darkside> maybe if you use some kind of relay system
[10:50] <Darkside> maybe there are 100mW 433MHZ modules...
[10:51] <trackuino> i will def'ly try 433 with AFSK. will stick it int he freezer to test for drift first :)

[11:03] <jcoxon> local hams
[11:03] <jcoxon> something like a ft790
[11:03] <jcoxon> ft817
[11:03] <jcoxon> funcube dongle
[11:05] <bcw> I'd happily buy one, but getting one today?
[11:05] <jcoxon> where are you based?
[11:05] <bcw> Aylesbury-ish
[11:05] <bcw> (Buckinghamshire)
[11:05] <jcoxon> (they aren't necessarily cheap
[11:05] <jcoxon> )
[11:06] <bcw> so the sort of thing I should have a license for then I guess?
[11:06] <jcoxon> no
[11:06] <jcoxon> as long as you don't transmit
[11:06] <bcw> well, yes
[11:06] <bcw> but I can't use half of the features!
[11:06] <bcw> but anyway, that's a side point
[11:06] <gonzo_> there are some scanners that will do SSB, and they are getting cleaper on ebay since there is little analogue traffic for peoplpe to listen to these days
[11:06] <bcw> should get my license anyway
[11:07] <jcoxon> you can then get your licence
[11:07] <bcw> indeed, but that's not going to happen today either! :)
[11:07] <mattltm-mobile> bcw: The foundation licence is easy. Do it :)
[11:08] <GW8RAK> Yupiteru 7100 does SSB and works well.
[11:08] <bcw> oh yeah, dead easy
[11:08] <bcw> I could pass it tomorrow I'd expect
[11:08] <mattltm-mobile> FRG9600 is a nice reciver for HAB too
[11:08] <bcw> but the clubs make it a pain
[11:08] <mattltm-mobile> I you dont mind traveling then BDARS do a great course
[11:09] <bcw> bangor and district or bromley and district?
[11:09] <mattltm-mobile> http://www.bdars.org/
[11:09] <bcw> Bromley then
[11:09] <bcw> :)
[11:10] <mattltm-mobile> Alan teaches the course.
[11:10] <mattltm-mobile> His name should be familier if you have ther course book...
[11:10] <mattltm-mobile> As he wrote all 3 of them :)
[11:10] <bcw> Thing is, I just want to turn up and do the exam and practical
[11:10] <jcoxon> i did that course
[11:10] <mattltm-mobile> bcw: Not allowed
[11:10] <bcw> I've got enough RF experience to pass it easily
[11:10] <bcw> well exactly, hence my comment about clubs making it a pain

[11:11] <mattltm-mobile> Its not the clubs, its the rules :)
[11:11] <bcw> I'm not convinced about that tbh ;)
[11:12] <mattltm-mobile> I think its one of those things where most people are new to radio and need the instruction so its easier to keep the format the same for everyone.
[11:12] <bcw> that's the point - I'm not 'new' to radio
[11:12] <mattltm-mobile> Besises, you go to a course full of newbies and you look like a god!
[11:12] <bcw> I'm 'new' to amateur bands
[11:13] <mattltm-mobile> I was in the same boat a year ago.
[11:13] <mattltm-mobile> But the course was interesting and I got to meet a bunch of new people all interested in talikng geek with me :0
[11:14] <mattltm-mobile> IIRC you can take the advanced exam only but you do have to do the foundation and intermediate first.
[11:15] <mattltm-mobile> I plan to sit my advanced next April and sit the US exams at the same time.
[11:15] <zyp> I'm also tempted to get a license
[11:15] <mattltm-mobile> jcoxon: Now you are local, would you be interested in sitting the advanced and the US licneces next year?
[11:15] <GW8RAK> Why do the US ones Mattltm-mobile?

[11:16] <mattltm-mobile> GW8RAK: Just because I can :0
[11:17] <jcoxon> mattltm-mobile, i only have foundation
[11:17] <mattltm-mobile> My examiner is qaulified to do the US ones too so I thought why not?
[11:17] <jcoxon> steve has a US licence

[11:17] <mattltm-mobile> Ahh, well if you want to do your 2E, I know just the man :0
[11:18] <mattltm-mobile> zyp: You will find it a walk in the park.
[11:19] <zyp> the question is what I'll use it for, once I get it
[11:19] <jcoxon> in theory we could fly HF flights and turn it on once out to sea
[11:21] <eroomde> zyp: being able to just legally build and test rf stuff is very useful

[11:37] <gonzo_> a shame there are no useable HF licence free allocations in the UK
[11:37] <gonzo_> there's one about 6.7MHz, but that's a 10mW erp limit
[11:38] <Darkside> path loss is far less on HF
[11:38] <Darkside> that'd be usable
[11:38] <Darkside> you'd need a decent antenna on the ground
[11:38] <Darkside> thats the problem
[11:40] <gonzo_> but HF is so noisy
[11:40] <Darkside> mmm
[11:43] <TimZaman> for controlling just a button (f.e. on a camera or somethign); a transistor would be a lot better than a reed relay, right? i guess reed relays suck up loads of power
[11:43] <jcoxon> TimZaman, yeah
[11:43] <Darkside> yeah use a fet or something
[11:43] <TimZaman> yeah i tried witha mosfet lieing around
[11:43] <Darkside> its possible the button just drops a microcontroller pin to ground
[11:43] <TimZaman> but for some reason it wouldnt switch
[11:43] <Darkside> so you could just connect it to a microcontroller or something
[11:44] <Darkside> see what voltages the switch goes to when you press it
[11:45] <BrainDamage> TimZaman: how did you wire it? the "problem" with mosfets, is that you'll need at least one wire electrically connected to the other circuit
[11:45] <TimZaman> BrainDamage: i wired it like i would wire a transistor
[11:45] <BrainDamage> yeah, that'd work
[11:46] <eroomde> jcoxon: i made another ed purchase
[11:46] <BrainDamage> is the mosfet "logic level"?
[11:46] <TimZaman> BrainDamage: no idea, i had it lieing around
[11:46] <BrainDamage> if not, check at which voltage is specified RDSon
[11:46] <TimZaman> im doing everything at 3v3
[11:46] <BrainDamage> power mosfets can require voltages much higher than logic level to switch
[11:47] <BrainDamage> 8-12V, even 20, is not uncommon
[11:47] <TimZaman> well yeah it was a highpower mosfet
[11:47] <TimZaman> to switch a 1w led
[11:47] <BrainDamage> you might want a mosfet driver chip then, one with a charge pump so it'll generate the correct voltages
[11:48] <TimZaman> arent there IC's?
[11:48] <TimZaman> switching IC's? since i need to control like 4/5 buttons
[11:48] <Darkside> TimZaman: again, check what levels are on the buttons
[11:48] <Darkside> you may be able to just wire microcontroller pins directly to it
[11:49] <jcoxon> quick payload test
[11:49] <Darkside> it means tying the grounds together too of course
[11:49] <jcoxon> eroomde, oh dear
[11:49] <TimZaman> Darkside: dont think i have the equipment
[11:49] <Darkside> TimZaman: a multimeter?
[11:49] <TimZaman> yeah
[11:49] <TimZaman> but what would you want me to measure
[11:49] <Darkside> thats all you need
[11:49] <BrainDamage> voltage across the button
[11:49] <Darkside> yeah
[11:49] <BrainDamage> both when it's pressed & not
[11:49] <Darkside> and see if one side is connected to ground
[11:49] <TimZaman> when not pressed?
[11:49] <Darkside> its possibly the button is just dropping a pin to ground
[11:50] <TimZaman> *trying now*
[11:50] <jcoxon> hooray
[11:50] <jcoxon> it works
[11:50] <jcoxon> eroomde, what was it?
[11:50] <TimZaman> 3.9V

[11:51] <TimZaman> Darkside: 0V
[11:52] <Darkside> ok
[11:52] <Darkside> see what it does when you feed 3.3v into it
[11:52] <Darkside> into the pin
[11:52] <Darkside> actually
[11:52] <Darkside> hmm
[11:52] <Darkside> maybe not such a good idea

[11:52] <jcoxon> oooooo
[11:53] <eroomde> it has a whole bunch of uses for things i want to do, but also for hab specifically it will be useful for calibrating NTX2s with temperature
[11:53] <TimZaman> but arent there simple switcher circuits?
[11:53] <eroomde> so we might actually be able to fly 2 or 3 payloads in the same band
[11:53] <jcoxon> looks like fun
[11:53] <jcoxon> i see
[11:53] <jcoxon> clever
[11:53] <jcoxon> right - i'm all set
[11:54] <jcoxon> payload constructed, batteries installed
[11:54] <eroomde> you'd probably have to use radios driven by a 12bit DAC for it to work, but that's not a huge deal

[11:54] <TimZaman> jcoxon: well, no. haha
[11:54] <jcoxon> :-(
[11:55] <TimZaman> haha but since i like you i will try
[11:55] <TimZaman> i'm gone for the weekend..
[11:55] <jcoxon> no worries
[11:55] <TimZaman> but i will take my portable with a simple whip
[11:55] <jcoxon> have a good weekend
[11:55] <TimZaman> :)
[11:55] <TimZaman> this time i do have a car though
[11:56] <TimZaman> so if we know where it lands, i could be available
[11:56] <TimZaman> tomorrow i've got some time off
[11:56] <jcoxon> great
[11:56] <TimZaman> make sure your batteries will survive
[11:56] <jcoxon> TimZaman, is 4xAA in parallel
[11:57] <jcoxon> so 2 sets
[11:57] <fsphil> should run for days that
[11:58] <TimZaman> i'm actually working on my polaroid camera haha
[11:58] <TimZaman> let's see if i can take some instants from near space
[11:59] <TimZaman> comes in at 600g though
[11:59] <jcoxon> payload mass is 280g here
[11:59] <TimZaman> !
[11:59] <fsphil> that will be really nifty TimZaman
[11:59] <BrainDamage> TimZaman: if the gnd of your controller & the cam are aligned, you can use a simple bjt
[12:00] <TimZaman> fsphil: i have seen rharrisson playing with the grease and getting it out etc.. but i think there is not enough mass to transfer the cold to the cameras inner parts
[12:00] <TimZaman> because ofcourse this camera is fairly mechanical
[12:00] <fsphil> if the camera is exposed it might have trouble
[12:01] <TimZaman> fsphil: meh.. my payloads have never seen temperatures below 10
[12:01] <fsphil> though if it's just the lens then it should keep itself warm enough - mine certainly did
[12:01] <fsphil> yea
[12:01] <fsphil> though the project cirrus one did freeze up
[12:02] <TimZaman> what exactly froze up?
[12:02] <fsphil> but I think maybe because they where only taking one picture a minute
[12:02] <fsphil> not enough exctivity
[12:02] <fsphil> activity*
[12:02] <fsphil> the lens
[12:02] <fsphil> zoomy bit
[12:02] <TimZaman> yeah okay but this cam would be sitting still till 20km
[12:02] <fsphil> well, autofocus
[12:02] <TimZaman> then take 10 pictures
[12:02] <fsphil> I'd consider maybe one of those hand warmers
[12:03] <TimZaman> yeah or just ducktape the thing in
[12:03] <TimZaman> some ducktape.. some toiletpaper, some ducktape. something like that should keep it warmish
[12:03] <TimZaman> but still, 30 minutes.
[12:03] <fsphil> it would be simple enough to test with a good freezer
[12:03] <TimZaman> -50c?
[12:04] <TimZaman> ;)
[12:04] <fsphil> -10c, but thicker air
[12:04] <TimZaman> because eh.. i got called yesterday by one of the bigger TV shows in holland
[12:04] <SpeedEvil> Mine goes to -45C or so.
[12:04] <TimZaman> they noticed that this might be a trending hobby
[12:04] <fsphil> it seems to be
[12:04] <SpeedEvil> Hotpoint.
[12:04] <TimZaman> -45? superconducting freezer
[12:05] <SpeedEvil> I picked one with stupidly thick insulation, and on boost, it goes rather colder than I was expecting.
[12:05] <fsphil> my next flight up seems to be getting some local attention this time
[12:05] <SpeedEvil> It took two days off - and full - to hit -18C
[12:05] <SpeedEvil> Once the risk of powercuts was over
[12:05] <TimZaman> i believe -22ish is the norm on freezrers right?
[12:06] <fsphil> hmm.. I must measure mine
[12:07] <SpeedEvil> -18.5 on mine normally.
[12:07] <SpeedEvil> It bouces between that and -19
[12:07] <zyp> I think -18 and below is defined as deep freeze
[12:07] <SpeedEvil> The colder, the longer stuff lasts.
[12:08] <SpeedEvil> But though stuff would last forever at -45C, getting stuff out is _brutal_
[12:08] <SpeedEvil> And you get massive amounts of condensation when you open it. It looks like a cloud chamber.

[16:03] <jcoxon> can see quite high

[16:19] <jcoxon> so 2.5m/s
[16:19] <jcoxon> with a 300g payload
[16:19] <jcoxon> 1.6kg howyee balloon
[16:19] <number10> would be good to have a webcam on the launch area
[16:19] <UpuWork> be too dark
[16:19] <fsphil> torrential rain here, so fog is pretty good :)
[16:20] <jcoxon> if we go for 2m/s
[16:20] <jcoxon> either it'll float
[16:20] <jcoxon> or it'll burst at 41140
[16:20] <daveake> Rain here. But that's Wales for you
[16:20] <number10> probably UpuWork - but I am sure someone cpuld set up an IR one
[16:20] <WillDuckworth> would be nice to have a 40k floater
[16:20] <fsphil> now that would be impressive
[16:20] <jcoxon> WillDuckworth, doesn't give much wiggle room
[16:20] <eroomde> Horus was a 40kg floater
[16:21] <eroomde> km*
[16:22] <number10> sounds better as a 40kg floater - but thats my sense of humour
[16:25] <WillDuckworth> looks like it might be a wet landing...... if it lands :D

[16:31] <fsphil> Just to prove you wrong UpuWork, I'm gonna launch three before the end of the year ;)

[16:57] <G4TNX> Hopefully, thats why we are on early
[16:58] <gonzo_> I think palle sold a lot of them. But I'm concentrating on the lower bands with that 3mtr mesh dish I gad off you
[16:58] <G0MJW> fsphil yes. Didn't work.
[16:58] <NigeyS> phil, whats my lat & lon ? lol
[16:58] <fsphil> G0MJW, wouldn't affect uploading telemetry running as root
[16:59] <fsphil> you not saved it NigeyS? :)
[16:59] <fsphil> I think I still have it on my laptop
[16:59] <NigeyS> first time ive used fl-digi since i put ubuntu on ere
[17:01] <fsphil> 51.487, -3.147 ?
[17:01] <gonzo_> does anyone have a url to a launch blog or similar for atlas3?

[17:04] <fsphil_2I0VIM> NigeyS, looks about right
[17:04] <Jessica_Lily> launch going ahead tonight?
[17:04] <NigeyS> schweet
[17:04] <fsphil_2I0VIM> seems to be! though possibly a little later than planned
[17:04] <NigeyS> ive got habhound up to
[17:04] <G0MJW> Right - second receiver up and running
[17:05] <fsphil_2I0VIM> but then that's normal enough :)
[17:05] <Jessica_Lily> i've just got home (from manchester to lancaster_
[17:05] <fsphil_2I0VIM> ooh nice NigeyS, lemme know if it does anything unexpected
[17:05] <Jessica_Lily> **lancaster)
[17:06] <G0MJW> G0NZO - I have also got a 3m dish now. Need a pedestal sorting out. Hopeful.
[17:06] <fsphil_2I0VIM> okie, time to venture into the attic and connect up the radio
[17:06] Action: fsphil_2I0VIM arms himself...
[17:06] <gonzo_> I'll see you on the moon then mike!
[17:07] <gonzo_> what's the QRG and data format for this launch?

[17:07] <fsphil_2I0VIM> USB
[17:07] <NigeyS> Caught signal 11
[17:07] <NigeyS> Aborting dl-fldigi due to a fatal error.

[17:08] <gonzo_> thanks fspjil
[17:08] <gonzo_> what's the bd rate/format?
[17:08] <fsphil_2I0VIM> it shouldn't matter NigeyS. hmm... ubuntu !!!! *waves fist*
[17:08] <G0MJW> How late will it be? I could do something else taking about an hour.
[17:08] <fsphil_2I0VIM> gonzo_, 50 baud rtty, if you're running dl-fldigi it will configure this for you if you select the payload from the drop-down and press autoconfigure
[17:09] <fsphil_2I0VIM> At hour at best...
[17:09] <gonzo_> rgr thanks. Will do.
[17:09] <fsphil_2I0VIM> I don't know if a launch has ever happened early .. except maybe Tim's last one
[17:09] <G0MJW> Define "Best" - least or most??
[17:09] <fsphil_2I0VIM> at least
[17:10] <fsphil_2I0VIM> it was planned for 18:00 GMT but will probably be a little after that
[17:10] <fsphil_2I0VIM> when jcoxon gets back we'll know better
[17:10] <G0MJW> Tnx. Just off out then
[17:10] <NigeyS> phil i got a problem with habhound

[18:57] <Upu_2E0UPU> there is this pulse every 10 seconds which covers 434.000 -> 434.200
[18:58] <NigeyS> eugh how annoying
[18:58] <number10> there is something like that near where I work Upu
[19:00] <G0MJW> Was teh float altitude 56m?
[19:00] <gonzo_> it's very noisy in the lpd section of 70cm where I am. on the omni this extercise would be a waste of time
[19:00] <gonzo_> on the yago it's bareable
[19:00] <gonzo_> yagi
[19:01] <OZ1SKY_Brian> Upu_2E0UPU: same problem here on 434075
[19:01] <Upu_2E0UPU> ah so not just me
[19:01] <Upu_2E0UPU> 650 is fine
[19:02] <OZ1SKY_Brian> Upu_2E0UPU: 433.000-434.200 is full of low power stuff
[19:03] <Upu_2E0UPU> yeah annoyingly
[19:03] <NigeyS> G0MJW, 36KM
[19:04] <G0MJW> It is at 56m at the moment which is impressive for Cambridge.
[19:04] <gonzo_> even in a 3khz chan it sounds like a whole orchestra tuning up
[19:04] <NigeyS> G0MJW, it's those tall trees!
[19:04] <OZ1SKY_Brian> Upu_2E0UPU: 434.200-4875 is normaly allways clear here. 650 is in our repeater segment, but no one on that freq near here

[19:35] <Upu_2E0UPU> sure either will be acceptable
[19:35] <NigeyS> wont be an alt .. not enough helium in there to push it past the 35km point i dont think

[19:37] <NigeyS> no Ed .. just what we've seen so far an underfill to get a slow ascent has resulted in not getting past 35k, im gonna go with phils idea that theres just not "punch" in there to break past 35km
[19:37] <CMos_UK> how do i fix that

[19:38] <casio> brilliant! When was it launched?
[19:38] <CMos_UK> (it's bcw, by the way!)
[19:38] <Upu_2E0UPU> can you tune to 434.073 Chris ?
[19:38] <Laurenceb_> so its doing rtty with an si4432?

[20:24] <Upu_2E0UPU> yeah lol
[20:25] <Dan-K2VOL> seems the ascent rate is a little high for trying for a float isn't it?
[20:25] <Upu_2E0UPU> nah
[20:25] <NigeyS> Dan-K2VOL, apex went upto 4.5 m/s above 25km and still managed it
[20:25] <NigeyS> which was kinda..odd
[20:26] <Dan-K2VOL> that's quite interesting
[20:26] <Upu_2E0UPU> Ava was 3.8m/s and floated
[20:26] <fsphil_2I0VIM> depends more on the neck lift I think
[20:26] <Upu_2E0UPU> its 1600g balloons
[20:26] <futurity> may i ask what the current shift is?
[20:26] <Upu_2E0UPU> 425
[20:26] <Dan-K2VOL> well my curiosity is what is lowering the density of the balloon
[20:27] <Upu_2E0UPU> probably made from "super sensitive" latex :)
[20:27] <Dan-K2VOL> is it meeting increasing resistance of the latex membrane?
[20:27] <fsphil_2I0VIM> that's my bet
[20:27] <Dan-K2VOL> it would seem to be super strong latex

[20:28] <fsphil_2I0VIM> yea

[20:29] <NigeyS> oo
[20:29] <Dan-K2VOL> and possibly a MPXV5010DP

[20:30] <Dan-K2VOL> the first is 0 to 0.145psi and the second is 0 to 1.45 psi
[20:30] <G0MJW> What happened there. Signal dropped. Came back
[20:30] <Dan-K2VOL> they output 0.2 to 4.5v analog output, temperature compensated
[20:30] <fsphil_2I0VIM> turbulence probably
[20:31] <fsphil_2I0VIM> I think it's about to turn

[20:33] <fsphil_2I0VIM> I think I see it
[20:33] <Upu_2E0UPU> its coming your way
[20:34] <fsphil_2I0VIM> I see one line, if it is that the other line is hidden behind a local strong carrier

[20:53] <gonzo_> are my decodes getting back to the sever ok now? And correct qth?
[20:53] <fsphil_2I0VIM> to be honest even drawing the horizon properly, it's still very nearly a circle
[20:53] <Upu_2E0UPU> all systems are a-ok
[20:53] <fsphil_2I0VIM> ooh good with the nasa voice Upu_2E0UPU

[20:54] <Laurenceb_> kind of
[20:54] <G0MJW> Poor thing is going to Skegness
[20:55] <TimZaman> haha are you guys whining about the fact that the green line shouldnt theoretically be a circle?
[20:55] <Upu_2E0UPU> even better at 40km :)
[20:55] <NigeyS> lmao tim, so blunt lol
[20:55] <Upu_2E0UPU> TimZaman good hack on the predictor to get the float
[20:55] <TimZaman> this is a 1600g hwoyee?
[20:55] <fsphil_2I0VIM> it should be very-nearly-but-not-quite-a-circle!
[20:55] <Upu_2E0UPU> yes it is
[20:55] <gonzo_> it's not the circle that's wrong, it's the map
[20:55] <NigeyS> its a god dam elipse i tell ya !
[20:55] <fsphil_2I0VIM> lol
[20:55] <TimZaman> Upu: Yeah recently i have been reading up on php hacking and xsitescripting
[20:55] <G0MJW> This was in the contest of Phil getting it beyond the horizon.
[20:55] <fsphil_2I0VIM> gonzo_, well put
[20:56] <TimZaman> i tried hacking fsphil_2I0VIM 's website but i did not succeed.
[20:56] <fsphil_2I0VIM> yay
[20:56] <fsphil_2I0VIM> I think
[20:56] <Upu_2E0UPU> :)
[20:56] <NigeyS> right so any XSS vulns turn up next week we know it was tim ok ;)
[20:56] <TimZaman> NigeyS: i find though, that it is better just to go to one's house and throw in a window than hacking someones computer
[20:56] <TimZaman> its just more satisfying
[20:56] <TimZaman> Anyway!
[20:57] <TimZaman> But hwoyee 1600g.. ascent of 4m/s
[20:57] <NigeyS> lol satisfaction guaranteed :D
[20:57] <TimZaman> it's going to pop at 39km
[20:57] <TimZaman> then it will go down
[20:57] <TimZaman> no float.
[20:57] <Upu_2E0UPU> you reckon ?
[20:57] <NigeyS> :o blasphemy!

[21:04] <TimZaman> nosebleedKT: i have used 1200baud on my 3rd flight, but its way to slow for a real live stream
[21:05] <Lunar_Lander> thanks
[21:05] <Laurenceb_> Lunar_Lander: can you hear it yet?
[21:05] <TimZaman> nosebleedKT: also its friggin complex getting the timing right i guess
[21:05] <fsphil_2I0VIM> yea, ssdv is not going to be doing video :)
[21:05] <nosebleedKT> :P
[21:05] <fsphil_2I0VIM> not yet anyway lol
[21:05] <nosebleedKT> Im just trying...
[21:05] <TimZaman> fsphil_2I0VIM: nah for video you got better ways of compressing
[21:06] <G4TNX> Turning?
[21:06] <Dan-K2VOL> TimZaman, the power draw though?
[21:06] <Robert_M0RJX> Upu_2E0UPU do you get local clicking
[21:06] <nosebleedKT> fsphil_2I0VIM: check your private plz
[21:06] <fsphil_2I0VIM> yea, better to use a standard like DVB -- it already does everything ssdv/video would do
[21:06] <Upu_2E0UPU> yeah loads its noisy as hell even with the NB set
[21:06] <TimZaman> Dan-K2VOL: just 1 Watt total
[21:06] <TimZaman> Dan-K2VOL: 5v 0.2A, i made a simple power supply that could cope to 6A
[21:06] <Upu_2E0UPU> you have to have NB set on the rig or I can hardly decode anything
[21:06] <gonzo_> just peaking signal here, it's the srongest yet!

[21:07] <TimZaman> Internal temp -17, wtf!
[21:07] <Robert_M0RJX> cool is that in the menu

[21:07] <G4TNX> coming back south now
[21:08] <TimZaman> Dan-K2VOL: my battery latst around 24 hours
[21:08] <CMos_UK> Could someone please let us know what the blue and green circles on the tracker are?
[21:08] <CMos_UK> I guess the blue is the furthest reception?
[21:08] <TimZaman> Dan-K2VOL: http://www.timzaman.nl/?p=1195&lang=en
[21:08] <Dan-K2VOL> 200mA includes for GPS and radio?
[21:08] <TimZaman> radio is 10mW, GPS is low as well once it has lock
[21:08] <TimZaman> maybe a little more than 200mA, okay.
[21:09] <Upu_2E0UPU> NB gets rid of the clicks but I have some horrendous what sounds like wide band data occasionally
[21:09] <fsphil_2I0VIM> CMos_UK, in theory -- though people usually manage further
[21:09] <Robert_M0RJX> NB Level ?
[21:09] <Randomskk> I wonder how much the managing-further is due to obscure propagation and how much is the map projection
[21:09] <TimZaman> CMos_UK: the green line is 5degrees or something
[21:09] <Upu_2E0UPU> you have a level ? your rig is better than mine
[21:09] <Upu_2E0UPU> I have on/off
[21:09] <Laurenceb_> loops
[21:10] <Randomskk> because in theory you really shouldn't be able to receive 70cm beyond the horizon without like, sporadic e
[21:10] <futurity> lol, i've left my rig for around 20+ minutes, have come back and the frequency is exactly the same! WOW!
[21:10] <Laurenceb_> Randomskk: you can drag the map up/down to get a better idea
[21:10] <Randomskk> meh, radio=magic
[21:10] <Upu_2E0UPU> Randomskk but I consistantly get it reception outside of the "horizon"
[21:10] <Dan-K2VOL> Interesting TimZaman, it would be nice to determine the power draw of the beagle board to compare directly
[21:10] <Dan-K2VOL> timZaman very nice looking board
[21:10] <CMos_UK> Thank you for that TimZaman and fsphil ;-)

[21:12] <Randomskk> better than at chu :P could you maybe bring it up next time you happen to be in cambridge?
[21:12] <Randomskk> no rush
[21:12] <jcoxon> Randomskk, i could return it tomorrow

[21:12] <jcoxon> number10, yeah its making sure the GPS is working

[21:21] <Upu_2E0UPU> such a strong signal its actually decoding even through the local noise , doubt it would if this was 300 baud

[21:24] <OZ1SKY_Brian> Laurenceb_: nope, south east is pretty poor from here
[21:24] <OZ1SKY_Brian> i mean south west
[21:24] <TimZaman> fsphil_2I0VIM: even in QR codes you can select FEC from 7% to 30%
[21:24] <fsphil_2I0VIM> TimZaman, because rtty doesn't, and the modes that do need more than two tones so a bit more complicated
[21:25] <Laurenceb_> i have mfsk-64 working
[21:25] <TimZaman> euhh
[21:25] <fsphil_2I0VIM> yea, but that's still difficult to do on a simple payload
[21:25] <TimZaman> dont see the problem if i compare it to your awesome ssdv

[21:26] <Lunar_Lander> what are you using on the dial?
[21:26] <Laurenceb_> code is on the wiki

[21:27] <fsphil_2I0VIM> mfsk has error correction iirc

[21:29] <Laurenceb_> jcoxon: temperature compensation isnt actiuve
[21:29] <Upu_2E0UPU> it is
[21:29] <gonzo_> btw, what is the drop in TX every few mins?
[21:29] <Laurenceb_> theres no heater
[21:29] <jcoxon> okay its got a heater
[21:29] <Upu_2E0UPU> Doing QSL cards jcoxon ? :)

[21:29] <Laurenceb_> mfsk
[21:29] <Upu_2E0UPU> if you are you're going to have a busy night :)
[21:30] <Laurenceb_> jcoxon: you added a heater?
[21:30] <Laurenceb_> sweet
[21:30] <jcoxon> Laurenceb_ yeah PID
[21:30] <jcoxon> hence why everything is cold apart from the radio
[21:30] <Laurenceb_> nice work.. but maybe power hungry
[21:30] <jcoxon> yeah thats my concern
[21:30] <jcoxon> as i said
[21:30] <Laurenceb_> it has lots of sinsulation
[21:30] <jcoxon> we'll just have to see
[21:30] <Laurenceb_> i cant see the radio status
[21:30] <jcoxon> yeah its 2degC

[21:32] <Upu_2E0UPU> 50 baud ftw
[21:32] <fsphil_2I0VIM> not helping me lol
[21:32] <Upu_2E0UPU> ok afk for a bit

[21:33] <gonzo_> sorry, just so astounded by the link, I'm unable to assist you in your gloom
[21:33] <jcoxon> Laurenceb_ well its (4xAA) x 2
[21:34] <Laurenceb_> ah
[21:34] <Laurenceb_> 3Ah arent they?
[21:34] <jcoxon> yeah
[21:35] <fsphil_2I0VIM> wobbly signal again
[21:35] <fsphil_2I0VIM> seems to happen after the power down
[21:35] <Lunar_Lander> damn still no signal
[21:36] <Lunar_Lander> 4.748.3
[21:36] <gonzo_> what is the power down? Is it a secret?
[21:36] <G0MJW> Er no 434.075
[21:36] <OZ1SKY_Brian> at 32000m i should come into view
[21:36] <fsphil_2I0VIM> I don't think that's the right frequency Lunar_Lander
[21:36] <OZ1SKY_Brian> i=it
[21:36] <TimZaman> only 9 more km to pop
[21:36] <Lunar_Lander> could you please give me the data for my dial?
[21:36] <fsphil_2I0VIM> ft790?
[21:37] <Lunar_Lander> yes
[21:37] <G0MJW> 4.075
[21:37] <fsphil_2I0VIM> 4.074.800
[21:37] <Lunar_Lander> ok
[21:37] <M0dts_Rob> good signal in the car here on my way home! shame there's no rtty decoder for Android...
[21:37] <fsphil_2I0VIM> there is M0dts_Rob :) though I never installed it
[21:37] <Lunar_Lander> what is that?
[21:38] <fsphil_2I0VIM> now one that uploads to the tracker, that would be neat
[21:38] <Laurenceb_> coming up on 30km
[21:38] <Lunar_Lander> got an S5 signal at 4.284.0
[21:38] <Lunar_Lander> what is that?
[21:38] <M0dts_Rob> ooh will have to look again then!
[21:38] <Lunar_Lander> someone nearby=
[21:38] <Lunar_Lander> ?
[21:38] <Lunar_Lander> maybe?
[21:38] <fsphil_2I0VIM> almost certainly Lunar_Lander
[21:38] nickle (57c23d82@gateway/web/freenode/ip. left irc: Ping timeout: 265 seconds
[21:38] <Lunar_Lander> ah
[21:38] <fsphil_2I0VIM> that's nowhere near the payload signal
[21:39] <Lunar_Lander> yeah
[21:39] <Lunar_Lander> another S at 4.160.0
[21:39] <Lunar_Lander> *S5
[21:39] <fsphil_2I0VIM> it's quicker to tune if you switch to FM mode
[21:39] <Lunar_Lander> ah
[21:39] <fsphil_2I0VIM> then switch back to USB
[21:39] <fsphil_2I0VIM> got a string at last, yay
[21:39] <fsphil_2I0VIM> 500.6km ;)
[21:39] <Upu_2E0UPU> hey thats not bad
[21:39] <gonzo_> congrats
[21:39] <G0MJW> Well done.
[21:40] <fsphil_2I0VIM> been a while since I decoded anything
[21:40] <Lunar_Lander> around 4.075.0 is noise
[21:40] <Laurenceb_> do you have a yagi?
[21:40] <gonzo_> how did you calc the dx phil?
[21:40] <G0MJW> Is this balloon going anywhere or is it just going to hang around the Wash all night?
[21:40] <fsphil_2I0VIM> gonzo_, dl-fldigi prints it on the hab data bit
[21:41] <Laurenceb_> 30km
[21:41] <Lunar_Lander> Laurenceb_ please don't laugh
[21:41] <fsphil_2I0VIM> colinear, same as upu really
[21:41] <gonzo_> ah yes, silly me
[21:41] <Lunar_Lander> I am sitting in my room and the radio has the normal whip antenna on it
[21:41] <Lunar_Lander> despite that I could receive ALPHA
[21:41] <fsphil_2I0VIM> alpha was closer
[21:41] <fsphil_2I0VIM> you might be able to decode this when it gets nearer you
[21:41] <Lunar_Lander> yes
[21:41] <Laurenceb_> im betting it pops and lands in east anglia
[21:41] <Lunar_Lander> when it gets to NL it should be
[21:41] <gonzo_> think it's miscalced here, unless it's in 100mtr units
[21:41] <fsphil_2I0VIM> good run of decodes now
[21:42] <Lunar_Lander> I think I could have received Tim's SCL2 if it hadn't crashed
[21:42] <G0MJW> gonzo - don't fret. Mine prints it too but gets it wrong. 5740km!
[21:42] <fsphil_2I0VIM> lol
[21:42] <fsphil_2I0VIM> it will only do that if you haven't entered your coordinates correctly
[21:42] <G0MJW> But I have....
[21:42] <fsphil_2I0VIM> hmm
[21:43] <gonzo_> have checked and it also puts me in the right place on the map, now it does anyway
[21:43] <OZ1SKY_Brian> where do you see the distance in fldigi?
[21:43] <OZ1SKY_Brian> sorry i was blind
[21:44] <gonzo_> is there a radar reflector on this payload?
[21:44] <G0MJW> One of those cacluations that only works East of 0?
[21:44] <fsphil_2I0VIM> I'm very west of 0
[21:44] <gonzo_> hehe' could be mike.
[21:44] <fsphil_2I0VIM> can you take a screenshot of the distance bit, and the coordinates entered in the configuration bit
[21:45] <fsphil_2I0VIM> I can test afterwards, see if there is a bug
[21:45] <G0MJW> FL Digi says bearing 178.7, distance 5740.1 yet I am in the right place on the map.
[21:45] <futurity> is the distance measurement in dl-fldigi in km or miles?
[21:45] <fsphil_2I0VIM> km
[21:45] <gonzo_> we could have a contest for ODX then phil
[21:45] <Lunar_Lander> oh well
[21:45] <SpeedEvil> Isn't it slant-range?
[21:45] <Lunar_Lander> how much is a yagi?
[21:45] <SpeedEvil> oh
[21:45] <fsphil_2I0VIM> great circle distance
[21:45] <fsphil_2I0VIM> my personal best is 560km
[21:46] <futurity> Lunar_lander: although I've not made one, I've been told that they are easy to make
[21:46] <G0MJW> Time, Lat and Long are all empty.
[21:46] <G0MJW> So is altitude
[21:46] <fsphil_2I0VIM> aaah
[21:46] <Lunar_Lander> yea
[21:46] <futurity> just bits of pipe, but by making one you can tune it to the frequency of your payload
[21:46] <Lunar_Lander> yes
[21:46] <gonzo_> Yep, pretty easy. But go for a wide bandwidth design, as they are less critical on dimensions
[21:46] <fsphil_2I0VIM> you haven't selected the payload G0MJW. select ATLAS and press autoconfigure
[21:47] <G0MJW> I did that!
[21:47] <Lunar_Lander> thanks gonzo_ & futurity
[21:47] <gonzo_> me too
[21:47] <fsphil_2I0VIM> did you restart dl-fldigi since?
[21:47] <fsphil_2I0VIM> it won't remember
[21:47] <gonzo_> the DL6WU yagi desighs are great, they just work
[21:47] <Lunar_Lander> yay
[21:47] <G0MJW> No - just did it again for good luck.
[21:47] <futurity> i'm not sure which type my yagi is, but a friend made it for another purpose
[21:48] <gonzo_> me to and it works now
[21:48] <G0MJW> Hey! Now it worked. Could it have timed out waiting for the launch?
[21:48] <fsphil_2I0VIM> don't think so
[21:48] <gonzo_> agh, only 300km. You win phil!
[21:49] <G0MJW> Well I did autoconfigure before.
[21:49] <fsphil_2I0VIM> give it time
[21:49] <fsphil_2I0VIM> if this floats you'll get much better distances gonzo_
[21:49] <Robert_M0RJX> Is this a cromer landing?
[21:49] <gonzo_> it's coming back south
[21:49] <fsphil_2I0VIM> if it floats it should head out over europe
[21:49] <fsphil_2I0VIM> the last one that did that was received over 700km away
[21:49] <G0ATW> Now live on GB3GG repeater on the BATC web site
[21:50] <G0MJW> Bug determined. After autoconfigure I checked it had done it right.
[21:50] <fsphil_2I0VIM> signal has faded here again, not decoding anymore
[21:50] <fsphil_2I0VIM> I think the QRM is going to limit what I can get tonight
[21:50] <G0MJW> 243.5 or 196.8km
[21:51] <OZ1SKY_Brian> hhmmm its +32000 now, but no signal
[21:51] <fsphil_2I0VIM> still below your horizon OZ1SKY_Brian -- you got mountains that direction?
[21:51] M0dts_Rob (~androirc@ left irc: Ping timeout: 252 seconds
[21:51] <OZ1SKY_Brian> no such thing as mountains here in Denmark, highest hill is 173meters, LOL
[21:52] <fsphil_2I0VIM> yikes!
[21:52] <OZ1SKY_Brian> flat as a pancake
[21:52] <fsphil_2I0VIM> signal has almost gone here
[21:52] <G0MJW> fsphill - can you add elevation to that set of data. Azimuth is useful but elevation is needed as well
[21:52] <fsphil_2I0VIM> could do G0MJW
[21:52] <OZ1SKY_Brian> fsphil_2I0VIM: could be the qrm on the freq, 075 is realy terriable
[21:53] <fsphil_2I0VIM> here too OZ1SKY_Brian
[21:53] <fsphil_2I0VIM> though at the moment I think it's moved behind an obstruction from here
[21:53] <G0MJW> Signal has hit S9 -back from behind the dish
[21:53] <fsphil_2I0VIM> there are some big hills where mattltm is -- I think it's those
[21:53] <Laurenceb_> landfall again
[21:55] <gonzo_> if the angles could be output in Yeasu format, then autotracking is possible
[21:55] <fsphil_2I0VIM> that's what I'm wondering
[21:55] RocketBoy_S2 (~RocketBoy@ left irc: Ping timeout: 258 seconds
[21:56] <fsphil_2I0VIM> what tracker do you have?
[21:56] <fsphil_2I0VIM> I've always wanted to get one - though they're a bit pricey
[21:56] <G0MJW> LVBTracker - but GS232 would be the protocol
[21:56] Dan-K2VOL (~Adium@74-143-44-42.static.insightbb.com) left irc: Quit: Leaving.
[21:56] <OZ1SKY_Brian> whats the freq now?

[21:56] <fsphil_2I0VIM> same OZ1SKY_Brian, 434.074.870
[21:56] <OZ1SKY_Brian> fsphil_2I0VIM: thanks
[21:57] <fsphil_2I0VIM> it hasn't budged from that frequency for a while - the oven is working well!
[21:57] <Lunar_Lander> 4.075.8?
[21:57] <fsphil_2I0VIM> 4.074.8 Lunar_Lander
[21:57] <Lunar_Lander> yes, sorry

[21:57] <Lunar_Lander> also correct
[21:57] <fsphil_2I0VIM> it's still quite low for you Lunar_Lander
[21:57] <jcoxon> temp is holding
[21:57] <Lunar_Lander> yes
[21:57] <Lunar_Lander> true
[21:58] <Laurenceb_> if this thing floats its going to be high
[21:58] <fsphil_2I0VIM> ah, just noticed the altitude!
[21:58] <gonzo_> the LVB is pretty cheap. Amsat do kits, but if you need to, you can just buy a pcb and get the parts yourself.
[21:58] <fsphil_2I0VIM> kits! never thought of that
[21:58] <Lunar_Lander> but nice to see how the predictor is working
[21:58] <G0MJW> .....which is what I did and it was easy.
[21:58] <Lunar_Lander> it predicted exactly something like that
[21:59] <fsphil_2I0VIM> do they provide all the parts? like the motors and casing?
[21:59] <G0MJW> Ah - no LVB tracker is the PC interface to the hardware
[21:59] <fsphil_2I0VIM> aah
[21:59] <gonzo_> Nope, the lvb is kist the tracking interface from the PC to your rotators
[21:59] <G0MJW> You need the hardware £500 unfortunately
[21:59] <fsphil_2I0VIM> that's the bit I'm stuck on ;)
[21:59] <x-f> what is the "TCXO" field in Atlas data?
[21:59] <fsphil_2I0VIM> signal getting stronger again
[22:00] <G0MJW> Tip - Pan Tilt Zoom Camera heads.
[22:00] <gonzo_> or look out for a chunky pan/tilt cctv mount
[22:00] <jcoxon> x-f, its the heater output from the PID
[22:00] <gonzo_> snap!
[22:00] <Lunar_Lander> yeah
[22:00] <jcoxon> to heat the radio crystal to keep it stable
[22:00] <Lunar_Lander> Temperature Crystal Oven
[22:00] <G0MJW> Save wavelength....
[22:00] <Laurenceb_> thats a pwm value?
[22:00] <fsphil_2I0VIM> my dog's doing his jedi mind thing again... brb
[22:00] <Lunar_Lander> translates into TCXO
[22:00] <TimZaman> its going to blow in ~20 minutes
[22:00] <G0MJW> Save==same
[22:00] <x-f> thanks, jcoxon and Lunar_Lander
[22:00] <fsphil_2I0VIM> oooh signal just disappered suddenly again -- another obstruction I guess
[22:01] <Lunar_Lander> jcoxon, is the CXO difficult to make?
[22:01] <Laurenceb_> weird direction change
[22:01] <Laurenceb_> ascent rate might be dropping

[22:04] <Lunar_Lander> but I like best the city of Braintree
[22:04] <Lunar_Lander> :)
[22:04] <OZ1SKY_Brian> still no signal here
[22:04] <OZ1SKY_Brian> should be in range now

[22:13] <Upu_2E0UPU> if fsphil_2I0VIM can get it from Northern Ireland
[22:13] <Jessica_Lily> xD
[22:13] <Lunar_Lander> hello Dutch-Mill
[22:13] <Jessica_Lily> how much do radios cost?
[22:13] <Lunar_Lander> you got acquisition?
[22:13] <Rob_M0DTS> i like the trick to fool float on predictor !
[22:13] <fsphil_2I0VIM> getting good decodes at the moment too
[22:13] <Dutch-Mill> Hi Lunar
[22:13] <Upu_2E0UPU> FT-817 is £550
[22:13] <Upu_2E0UPU> but you can get cheaper ones on E-Bay
[22:13] <G0MJW> Dongle is £120.
[22:13] <Upu_2E0UPU> not cheap
[22:13] <gonzo_> Or a FunCube Dongle
[22:13] <Upu_2E0UPU> yeah or funcube dongle
[22:13] Hiena (~boreger@ left irc: Remote host closed the connection
[22:13] <OZ1SKY_Brian> looks like 435Hz shift to me
[22:13] <fsphil_2I0VIM> dongle not so good in noisy areas though
[22:13] <gonzo_> (have to stop doing thius mike!)
[22:13] <gonzo_> true
[22:14] <fsphil_2I0VIM> OZ1SKY_Brian, yes it's about that
[22:14] <Lunar_Lander> btw about music
[22:14] <Jessica_Lily> cheap hobby you folk have xD
[22:14] <gonzo_> you can pick up older radio's on ebay
[22:14] <Lunar_Lander> we said Black Eyed Peas is not so good
[22:14] <Lunar_Lander> but I know a good HAB song
[22:14] <Lunar_Lander> (no, not Eminem again)
[22:14] <Jessica_Lily> what radio am i looking for? (search term)
[22:14] <Upu_2E0UPU> lol Jessica_Lily you think its cheap then you start learning and it adds up :)
[22:14] <G0MJW> Whats withthis xD
[22:14] <Rob_M0DTS> 99 red balloons
[22:14] <Lunar_Lander> "Chariots of Fire" by Vangelis
[22:14] <Upu_2E0UPU> FT-817
[22:14] <Lunar_Lander> yea Rob_M0DTS :)
[22:14] <Jessica_Lily> Upu_2E0UPU yeh it was sarcasm :P
[22:15] <Jessica_Lily> i didn't think it was cheap
[22:15] <fsphil_2I0VIM> 530km range from me
[22:15] <Upu_2E0UPU> sorry Jessica_Lily :/ You can get radios for ~ £90
[22:15] <Lunar_Lander> Jessica_Lily, FT-790R works too
[22:15] <Lunar_Lander> yea
[22:15] <Upu_2E0UPU> that can recieve
[22:15] <gonzo_> search for 70cm or 430MHz and SSB (or USB)
[22:15] <jcoxon> float
[22:15] <fsphil_2I0VIM> FT-790R often go for about £100
[22:15] <fsphil_2I0VIM> and they're a great little radio for hab'ing
[22:16] <dodweld> what about a good scanner aor8200?
[22:16] <Upu_2E0UPU> where is Tim when you need to gloat
[22:16] <Jessica_Lily> whats the real difference between the two radios?
[22:16] <fsphil_2I0VIM> not floating yet jcoxon
[22:16] <G0MJW> James - stop saying that - every time you do it goes up a bit
[22:16] <Upu_2E0UPU> 817 is portable and has batteries
[22:16] <jcoxon> G0MJW, it'll oscillate
[22:16] <Upu_2E0UPU> very small, very sensitive
[22:16] <gonzo_> and there are some scanners that will receive in SSB mode, and scanner prices are dropping because there is very little analogue stuff to listen to these days
[22:16] <G0MJW> Only joking....
[22:16] <jcoxon> different path to what i expected
[22:16] <fsphil_2I0VIM> 790 is portable and also has batteries, but is limited to the 70cm band and can be quite difficult to find now (they're old)
[22:16] <Martin100> 36617m - though 120,000ft !
[22:16] <jcoxon> wasn't expecting going east
[22:17] <fsphil_2I0VIM> suppose the predictor doesn't really have wind data for up there jcoxon
[22:17] <Upu_2E0UPU> you could try your local radio club Jessica_Lily
[22:17] <G0MJW> S9+ now
[22:18] <OZ1SKY_Brian> 713km and weak rtty trace, no decode yet
[22:18] <fsphil_2I0VIM> it's scary how good your setup is OZ1SKY_Brian lol
[22:18] <Jessica_Lily> i should try and build one :P that'd fail but it'd be fun
[22:18] <Jessica_Lily> we did quite a bit on superhets in electronics
[22:18] <OZ1SKY_Brian> looks like a freq drift at tx startup
[22:18] <jcoxon> OZ1SKY_Brian, thats the tuneup
[22:18] <OZ1SKY_Brian> jcoxon: rgr
[22:19] <jcoxon> the radio temp is stable i think
[22:19] <jcoxon> (though it doesn't appear on the tracker)
[22:19] <Jessica_Lily> what happens if i goes out to sea and drops?
[22:19] <Upu_2E0UPU> jcoxon frequency is rock solid
[22:19] <Upu_2E0UPU> Jessica_Lily it gets wet
[22:19] <jcoxon> Jessica_Lily, don't expect it to return

[22:20] <Jessica_Lily> that'd suck
[22:20] <Jessica_Lily> you'd loose all your data

[22:52] <Randomskk> totally
[22:52] <Upu_2E0UPU> it needs to be used
[22:52] <Upu_2E0UPU> 1600g
[22:52] <Randomskk> we're getting more He in shortly
[22:52] <Lunar_Lander> lol 16600
[22:52] <Upu_2E0UPU> Anyone want to just use Hydrogen and get the job done ? :)
[22:52] <fsphil_2I0VIM> I'm also launching a 1600g in the next four weeks with the aim of floating
[22:53] <fsphil_2I0VIM> Upu_2E0UPU, I'm going to launch a 600g balloon with H2 :)
[22:53] <Upu_2E0UPU> yay :)
[22:53] <jonsowman> jcoxon: just let us know when
[22:53] <Upu_2E0UPU> Helium is getting so expensive
[22:53] <fsphil_2I0VIM> I just need to find out what attachments I need for the cylinder
[22:53] <Lunar_Lander> did anybody attempt methane flights btw?
[22:53] <jonsowman> i'm going to get 2 more L-type cylinders in next week
[22:53] <jcoxon> truthfully i could be ready for next friday
[22:53] <jcoxon> or sat
[22:54] <Upu_2E0UPU> do you want the balloon jcoxon or do you have one ?
[22:54] <Randomskk> friday would be better from a notam point of view
[22:54] <Randomskk> it expires saturday technically
[22:54] <Upu_2E0UPU> oh
[22:54] <Randomskk> we should have it renewed by then too, but...
[22:54] <Upu_2E0UPU> can I make a request ?
[22:54] <Laurenceb_> does it have a chute on?
[22:54] <Upu_2E0UPU> 434.650 pls
[22:54] <jcoxon> Upu_2E0UPU, but those repeaters...
[22:54] <fsphil_2I0VIM> lol
[22:54] Nick change: fsphil_2I0VIM -> fsphil
[22:54] <jonsowman> i'm busy next weekend unfortunately but Randomskk is around?
[22:54] <jonsowman> also some other cusf people, ed c perhaps
[22:54] <Upu_2E0UPU> **** the repeaters :)
[22:55] <Randomskk> yea I am I think
[22:55] <jonsowman> Upu_2E0UPU: absolutely
[22:55] <jcoxon> well let see
[22:55] <Randomskk> Upu_2E0UPU: was that "key up" the repeaters? :P
[22:55] <jcoxon> need better ground weather
[22:55] <Upu_2E0UPU> secondary users :)
[22:55] <jcoxon> or we'd be repeating
[22:55] <fsphil> I'll give a repeater operator £5 if they even notice a payload is transmitting on 434.650
[22:55] <jcoxon> i actually think that our ascent rate was too high
[22:55] <Upu_2E0UPU> make the payload transmit the tone
[22:55] <OZ1SKY_Brian> 434.400-434.475 is normaly pretty clear and free of LPD
[22:55] <Upu_2E0UPU> we'd get more listeners
[22:55] <NigeyS> so they may get a bit interrupted talking about their corns, and warts, nevermind.
[22:56] <fsphil> you think I should use 434.650 for my float?
[22:56] <jonsowman> can't believe it burst
[22:56] <Upu_2E0UPU> trouble is OZ1SKY_Brian we use NTX2 modules
[22:56] <OZ1SKY_Brian> Upu_2E0UPU: whats there freq range?
[22:56] daveake_ (c3f86fe0@gateway/web/freenode/ip. left irc: Quit: Page closed
[22:56] <Upu_2E0UPU> they only come in .075 and .650 but there is alot of work going on to use different transmitters that we can adjust the transmission frequency
[22:57] TimZaman (~chatzilla@D97B081C.cm-3-4a.dynamic.ziggo.nl) joined #highaltitude.
[22:57] <Dutch-Mill> I vote for 434.650 less qrm on that frequency
[22:57] <OZ1SKY_Brian> Upu_2E0UPU: ok then 650 is a much better freq
[22:57] <jonsowman> also don't count on my car being usable by next weekend
[22:57] <jonsowman> hopefully i'll have it sorted in the next couple of days
[22:57] <gonzo_> there are som 863meg allocations that allow 500mw, though that would reduce the number of tracking stations
[22:57] <fsphil> I'll use .650 for that then
[22:57] <OZ1SKY_Brian> 434.075 is terriable
[22:57] <TimZaman> Houston we have a problem]
[22:57] <Upu_2E0UPU> 650 has my vote
[22:57] <Lunar_Lander> yea
[22:57] <TimZaman> Well, Upu, i see we have tied
[22:57] <OZ1SKY_Brian> 650 for me too
[22:57] <Randomskk> jonsowman: you're busy either way so I guess it doesn't make much odds
[22:57] <Upu_2E0UPU> lol it floated TimZaman :)
[22:57] <Lunar_Lander> can somone buy me a .650 and send it to me?
[22:57] <jonsowman> yeah true Randomskk q
[22:57] <Lunar_Lander> as radiometrix only ships in the UK
[22:57] <Lunar_Lander> and I got a .075
[22:57] <fsphil> Lunar_Lander, farnell
[22:57] <Lunar_Lander> ah yea
[22:58] <TimZaman> Upu yeah for almost 40mins
[22:58] <fsphil> also -- unless you're planning to float it doesn't really matter
[22:58] <TimZaman> Upu still, Why did it float
[22:58] <fsphil> .075 is fine
[22:58] <gonzo_> still hearing but far to weak for data
[22:58] <Upu_2E0UPU> gonzo_ they have a duty cycle on them
[22:58] <fsphil> I've used .075 for all my flights so far

[22:59] <gonzo_> that counts as duty cycle?
[22:59] <Dutch-Mill> Lunar Farnell sells .650 in Germany
[22:59] <Upu_2E0UPU> lol gonzo_ interesting interpretation :)
[22:59] <fsphil> OZ1SKY_Brian, most of our chase was through rural countryside so that probably helped
[22:59] <Lunar_Lander> Dutch-Mill, yea
[22:59] <Lunar_Lander> thanks :)

[23:00] <jcoxon> that parachute is actually working
[23:00] <Upu_2E0UPU> however gonzo_ my suggestion is use 6 transmitters and rotate between them
[23:00] <jcoxon> i'm suprised
[23:00] <Upu_2E0UPU> how come ?
[23:01] <gonzo_> I was going to suggest just change freq each 10mins
[23:01] <G0MJW> Nice colour parachute
[23:01] <Darkside> aww no float
[23:01] <Upu_2E0UPU> it floated
[23:01] <fsphil> there was for a while Darkside
[23:01] <Upu_2E0UPU> just not for long
[23:01] <Darkside> well, not a long float

[23:03] <fsphil> yea it handle that flight perfectly

[23:04] <fsphil> suspect that'll grow as I add bits NigeyS ;)
[23:05] <jonsowman> 17mb is nothing
[23:05] <Rob_M0DTS> habhound available or in beta?
[23:05] <NigeyS> yeah, always the way, i reckon it'll stay fairly low though
[23:05] <fsphil> sorta of alphabeta
[23:05] <fsphil> it only compiles on linux at the moment
[23:05] <fsphil> but is stable
[23:05] <NigeyS> Rob, get ureself a coffee or 3 before attempting to compile it..lol
[23:05] <Rob_M0DTS> ok
[23:05] <gonzo_> just re-reading the docs.... the 863 meg does not have to be 10% duty cycle, you can do other things to mitigate interference
[23:05] <dodweld> cut the chute - drop it on the beach ?
[23:06] <Rob_M0DTS> not got linux on any machine at present so i'l hang on for now ;-)

[23:16] <Upu_2E0UPU> it works
[23:16] <Upu_2E0UPU> definitely
[23:16] <jcoxon> yeah that the thing
[23:16] <jcoxon> it would be crazy to keep it at ground temp
[23:16] <jcoxon> so it'll drift early on
[23:17] <Upu_2E0UPU> what provides the heat ?
[23:17] <Jessica_Lily> would you make them waterproof and i donno somehow make it more retrievable
[23:17] <Jessica_Lily> like when designing a payload
[23:17] <jcoxon> resistors
[23:17] <Upu_2E0UPU> Jessica_Lily they do float

[23:20] <fsphil> I've been playing with rtty over laser
[23:21] <TimZaman> yeah thatd work
[23:21] <SpeedEvil> Funky.
[23:21] <Lunar_Lander> jcoxon, how do you build a crystal oven?

[23:21] <joph> i'll build a laser projector
[23:21] <gonzo_> looking at the map, you may be able to use the ferries to retrieve it
[23:21] <joph> rtty via laser is also great
[23:21] <SpeedEvil> Same as with any other. Little wrap of insulation round the crystal, and a heater either on the crystal or on the box

[23:22] <gonzo_> you shoudl fsk the laser
[23:22] <joph> fsphil, fixed mount or adjustable via stepper?

[23:22] <fsphil> joph, not moving it at all. just modulating
[23:22] <joph> yeah
[23:23] <SpeedEvil> Or if not a foam box, put a layer of foam under it, a layer of foam over it, and use thin wires to connect to the PCB.
[23:23] <DanielRichman> there. I reparsed the last point only. It looks better on the right now (though clicking any of the old points is still ugly).

[23:33] <CMos_UK> LOL
[23:34] <Upu_2E0UPU> I'm out of horizon
[23:34] <Upu_2E0UPU> all yours G0ATW
[23:34] <CMos_UK> one person left
[23:34] <fsphil> we need receivers in the north sea
[23:34] <Upu_2E0UPU> should get it all the way down unless there is anything in the way
[23:34] <fsphil> not just people who enter their coordinates wrong
[23:35] <CMos_UK> Norfolk is very flat
[23:35] <CMos_UK> my brother in law lives out there
[23:35] <CMos_UK> if you're serious about needing trackers out that way I can have a word :)
[23:35] <Martin100> If it had landed a bit earlier you might have ended up on one of the ferries out of Hull to NL
[23:35] Nick change: Upu_2E0UPU -> Upu
[23:36] <Upu> lost it G0ATW ?

[23:37] <jcoxon> anything else i should add to the payload?
[23:37] <G0ATW> just hear tones
[23:37] <jcoxon> anything that annoyed you?
[23:38] <jcoxon> i'll reduce the number of GPS checks
[23:38] <jcoxon> from 10 to a bit more
[23:38] <Upu> just 075 which isn't your fault
[23:38] <Upu> it was running an NTX2 ?
[23:38] <jcoxon> yeah
[23:38] <Upu> ok
[23:38] <jcoxon> im not going to 650
[23:38] <jcoxon> mainly as i've got loads of 075 :-)
[23:38] <Upu> its hardly hampered us
[23:38] <number10> loads ;)
[23:39] <jcoxon> well i had 3
[23:39] <jcoxon> now i've got 2
[23:39] <Upu> good flight
[23:39] <fsphil> I've got about 2 of each atm
[23:39] <G0ATW> gone!
[23:39] <Upu> G0ATW in the sea :)
[23:39] <fsphil> I'll stick with the .075's for the short range flights
[23:39] <number10> I wondered why you could afford to keep sdoing one way flights
[23:39] <jcoxon> number10, i have lots of bits
[23:39] <jcoxon> this payload has flown once before
[23:39] <jcoxon> as atlas2
[23:40] <jcoxon> it was stuck in a tree for a few weeks

[23:42] <LazyLeopard> Yeah, there were lots of folk tracking when I first looked in. ;)
[23:42] <fsphil> big gap over europe though :) apart from holland
[23:43] <Lunar_Lander> yea
[23:43] <Lunar_Lander> and germany
[23:43] <jcoxon> the one thing in the way of atlas4 is probably MW3
[23:43] <Lunar_Lander> XD
[23:43] <Lunar_Lander> btw how comes the change in telemetry?
[23:43] <LazyLeopard> Anyway, Intermediate course to help with in the morning, so I'm off to bed. G'night, and thanks for the entertainment, James. ;)
[23:44] <Lunar_Lander> gn8 LazyLeopard
[23:44] <Lunar_Lander> jcoxon, just before landing it started to send out less info
[23:44] <number10> MW3?
[23:44] <Lunar_Lander> the photosensor information disappeared for instance
[23:44] <Lunar_Lander> Call of Duty 8 I assume

[23:46] <jcoxon> the data is there
[23:46] <Lunar_Lander> ah
[23:46] <Lunar_Lander> what kind of photosensor did you have?
[23:46] <jcoxon> just a photodiode

[23:47] <number10> well Im off - look forward to next fridays launch jcoxon... non of this messing about with computure games - get atlas4 built ;)
[23:47] <Lunar_Lander> so the output also was abitrary
[23:48] <fsphil> lol
[23:48] <jcoxon> Lunar_Lander, well its relative
[23:48] <Lunar_Lander> yea
[23:48] <jcoxon> but yeah its not tuned to a standard unit
