[00:32] <Matt_soton> lets hope this HF transitter goes better then last time...
[00:32] <SpeedEvil> Indeed.
[00:38] <NigeyS> SpeedEvil, alarm set? :)
[00:38] <SpeedEvil> yes.
[00:38] <Darkside> Matt_soton: are you launching this time?
[00:38] <NigeyS> SpeedEvil, if it turns out not to be the "sale" announcement, i will cry lol
[00:38] <SpeedEvil> It won't be.
[00:39] <SpeedEvil> Or it might be I suppose
[00:39] <NigeyS> i think if they did that theyd piss off qite alot of people
[00:40] <SpeedEvil> I have doubts it'll be other than 'will go on sale tomorrow'
[00:40] <NigeyS> meh
[00:41] <Matt_soton> Darkside: indeed, should help :P
[00:42] <Darkside> yeah
[00:42] <Darkside> i doubt the 27MHz transmitter will go much further than LoS though
[00:42] <Darkside> 50 baud?
[00:43] <SpeedEvil> 27M can skip lots.
[00:43] <Darkside> at 10mW you're really goign to be pushing it
[00:43] <SpeedEvil> 27 has the that as a problem too.
[00:43] <SpeedEvil> Because it can skip, you're now getting interfered with by over-the-horizon.
[00:44] <Darkside> yeah
[00:44] <Darkside> i've done a 40m payload with about 50mW
[00:44] <Darkside> didn't get any skip
[00:44] <SpeedEvil> And also it is not so line-of-sight on the ground.
[00:44] <SpeedEvil> This means that nearby sources aren't blocked by LOS so much
[00:47] <MLow> raspi!
[00:48] <MLow> i'll send mine is space if i get one
[00:49] <Matt_soton> 27MHz also has the property that its easier to owrk with when wanting to try something new
[00:49] <Matt_soton> 27M is almost DC compared to 434 MHz
[00:50] <SpeedEvil> I find it kinda sillythat my slowest processor is faster than 434

[01:36] <Pavix> So are sales for rasberrypi locked to a specific reigon or can ppl in the US buy one?
[01:36] <SpeedEvil> Anyone.
[01:36] <SpeedEvil> Well - with the cash.
[01:36] <Pavix> sweet
[01:36] <SpeedEvil> Note that there are >100K on the mailing list, and 10K items.
[01:36] <SpeedEvil> So unless you're prompt, you may not get one of the first batch.
[01:37] <Pavix> Hmm, I think it'll be 2am central when they go on sale. Might be worth losing sleep to grab one, if I'm quick enough
[01:42] <SpeedEvil> Think that's right - a little over 4 hours
[01:46] <Randomskk> oh GOD
[01:46] <Randomskk> the fucking LNA shunts the RF IN to ground
[01:46] <Randomskk> so now when I solder it up
[01:46] <Randomskk> my rf line is a DC short to my ground line
[01:46] <Randomskk> and I go "oh no, there's a short! it must be... oh no, underneath the LNA!"
[01:46] <Randomskk> some amount of reworks later: datasheet: FFFFFUUUUUUU----
[01:47] <SpeedEvil> :/
[01:47] <SpeedEvil> Any explosions?
[01:47] <Randomskk> not connected any power yet
[01:47] <Randomskk> just very very very annoyed that I spent 30 minutes reworking a tiny annoying part several times for no reason at all

[04:28] <spacekitteh> eroomde: Looks like i'm the code bitch for my assignment, despite there being two actual software engineers on the team
[04:31] <Pavix> lol irc drama
[04:31] <spacekitteh> irc drama makes me laugh and/or cry depending if i'm involved or not
[04:32] <Pavix> Yea, I like to keep as far away from it as possible. Something about a dude and his wife who he might have met on IRC....I dunno
[04:33] <Pavix> Sorry to hear about your assignment, what kind of coding are you doing?
[04:34] <spacekitteh> GNC and image processing for an autonomous search and rescue blimp
[04:34] <Pavix> sweet, sounds fun. What are you using to capture images?
[04:34] <spacekitteh> as high res a camera as the onboard computer can handle
[04:34] <spacekitteh> means we can orbit from a higher altitude
[04:35] <spacekitteh> get a larger search area
[04:35] <Pavix> might check into cmucam3, I don't know what res it uses but I think it has onboard image processing
[04:36] <spacekitteh> hmm
[04:36] <spacekitteh> neat
[04:37] <Pavix> Yea, we're gonna use it for our boat project for object detection and avoidance. Not hard to detect a 10 story tall shipping barge with a human eye, the trick is to recognize it with a robotic one
[04:37] <spacekitteh> hmm
[04:37] <spacekitteh> looks to be about as expensive as a gumstix+i2c camera
[04:38] <Pavix> I think it's in the $200-$300 range
[04:38] <spacekitteh> yup
[04:38] <spacekitteh> we only have a $700 budget
[04:39] <Pavix> Ahh, might not be worth it. I can't code, at all. So I try to rely on stuff like that if it means my friend doesn't have to work harder

[04:39] Action: spacekitteh giggles
[04:39] <spacekitteh> 7 people in the team
[04:40] <spacekitteh> i'm doing GNC + telemetry and quite possibly image processing
[04:40] <spacekitteh> telemetry is simple enough
[04:40] <spacekitteh> i've got so much to do this year >.<
[04:41] <Pavix> Sounds pretty busy
[04:41] <spacekitteh> yep
[04:41] <Pavix> But fun, I get bored so anything to keep that from happening is usually a good thing
[04:41] <spacekitteh> on top of that i have to get into shape and join a roller derby team, build a ham radio, visit england and melbourne, and move out of home
[04:44] <Pavix> ugh, don't talk to me about shape. I have a sitdown job and I let myself get lazy...Its not good at all. I swear if I have one more cheeseburger richard simmons is gonna burst into my apartment wearing spandex and give me a hug....not good
[04:44] <spacekitteh> lol
[04:44] <spacekitteh> i've started exercising every day and dieting a couple of weeks ago
[04:44] <spacekitteh> i'm so sore ._.
[04:44] Action: spacekitteh curls up under her desk
[04:45] <Pavix> I am hoping next year is when we get a house. Not only for having a room where I can do my soldering etc as well as computer stuff but also so we can buy one of those treadclimbers
[04:45] <spacekitteh> indeed
[04:45] <spacekitteh> i just want somewhere close to a skating rink
[04:45] <spacekitteh> lol
[04:46] <Pavix> But we'll see. lots of money to buy a house
[04:46] <spacekitteh> yeah o;
[04:47] <spacekitteh> rent is expensive as hell here too
[04:47] <Pavix> It drove me crazy a year or 2 back I was reading cnn and they were saying some people were buying their houses in cash. Seriously who has $300,000 USD in cash just laying around collecting dust
[04:48] <spacekitteh> my parents do
[04:48] <Pavix> I picked the wrong profession
[04:48] <spacekitteh> they outright bought this house at $800k
[04:48] <Pavix> holy shit
[04:48] <Pavix> What do they do?
[04:48] <spacekitteh> they're retired now but dad was an accountant and mum was a school dental therapist
[04:50] <Pavix> Nice, they must have managed their money well

[06:42] <Upu> they should have put it on Amazon
[06:43] <NigeyS> yup
[06:44] <NigeyS> with Rs showing the wrong page farnells getting the full wack of traffic.. :/
[06:44] <Upu> so who got up to buy one ?
[06:44] <NigeyS> meee and speedy
[06:44] <Upu> did you get one ?
[06:44] <SpeedEvil> I got reserve link only
[06:44] <NigeyS> hah cant even get to a site to get 1
[06:44] <NigeyS> farnells DOA
[06:44] <Upu> http://www.youtube.com/watch?v=rX7wtNOkuHo <-
[06:45] <SpeedEvil> I did get successful reserve
[06:47] <NigeyS> me to, so im :)
[06:51] <Upu> who wanted a RFM22B breakout ? http://i.imgur.com/ZfRrV.png
[06:52] <Darkside> Upu: you may as well wire GPIO0 and 1 directly to the TXANT and RXANT pins
[06:52] <Darkside> since thats going to be the most common configuration
[06:52] <Upu> yeah ? Ok will do thanks
[06:53] <Darkside> this is the one downside with teh RFM22
[06:53] <Upu> Did you see my message about the soldering the MAX6's ?
[06:53] <Darkside> it takes up so much board real estate
[06:53] <Darkside> nope
[06:53] <Darkside> i see you managed to solder some up :-)
[06:53] <Upu> you know you tack the board in place using the corner pads then do the others
[06:53] <Darkside> yeah i know tha
[06:53] <Upu> yeah did 8 yesterday :)
[06:53] <Darkside> whats whati always do
[06:53] <Upu> well don't
[06:54] <Upu> for some reason the 0.7mm pads the solder just wouldn't flow into them easily
[06:54] <Darkside> flux
[06:54] <Upu> however the 0.8mm pads perfect no issues
[06:54] <Darkside> lots of flux
[06:54] <Upu> no amount of flux
[06:54] <Darkside> heh
[06:54] <Darkside> i'd be using flux
[06:54] <Upu> I drowned it in flux
[06:54] <Upu> seriously
[06:54] <Darkside> loool
[06:54] <Upu> to do the 0.7mm pad you need to push the iron all the way in
[06:55] <Darkside> easily done
[06:55] <Upu> on the 0.8mm pads you can just touch the pad ont he PCB and the solder flows
[06:55] <Upu> so tack the 0.8mm pad first
[06:55] <Darkside> mm ill need to order some
[06:55] <Upu> got stock shops open
[06:55] <Upu> don't forget the discount code UKHAS
[06:56] <Darkside> how much is shipping?
[06:57] <Upu> £8 or so ?
[06:57] <Upu> International signed
[06:57] <Darkside> cool
[06:59] <Upu> if yuo put your details in the shop has the shopping rates coded into it and they seem to be accurate
[06:59] <Darkside> will have to order a few
[06:59] <Darkside> a few of the MAX-6Qs
[06:59] <Upu> got loads left
[07:00] <Darkside> can i get my order tax free? :P
[07:00] <Upu> though that may change when I make a board with Level converters on so you can stick it straight into an Arduino
[07:00] <Upu> sorry no
[07:00] <Darkside> aaaaawwwwww
[07:00] <Upu> if we do that we have to start filling out export paper work and we just aren't making enough to cover it
[07:00] <Darkside> i got that when i got the NEO-6Qs
[07:00] <Darkside> got a shitload off
[07:01] <Upu> if you use the code and pay by paypal we make about 11%
[07:01] <Upu> and doing export documentation for the tax man
[07:01] <Upu> never mind :)
[07:01] <Darkside> lol
[07:02] <Upu> just see what it comes too even with the VAT on its going to be cheaper I'm sure
[07:02] <Darkside> $14 shipping to australia
[07:03] <Upu> whats that in english ?
[07:03] <Darkside> uhm
[07:03] <Darkside> $14
[07:03] <Upu> oz dollars or american ?
[07:03] <Darkside> pretty much the same at the moment
[07:03] <Darkside> we've been hovering around parity for a few months
[07:04] <Darkside> BAHAHAHa
[07:04] <Darkside> its better atm
[07:04] <Darkside> 1 AUD = 1.08USD
[07:04] <Upu> £8.78
[07:04] <Upu> so I wasn't far off
[07:05] <Upu> ok work bbl

[08:05] <_Hix> how come raspberry pi is only pre order on rs?
[08:07] <Darkside> lots of demand, no supply
[08:07] <UpuWork> they should get monkey on the case
[08:08] <_Hix> thought using rs and farnell was the point in meeting demand
[08:08] <Darkside> uhh
[08:08] <Darkside> rs and farnell are just distributors
[08:08] <UpuWork> millhouse "haha" ?
[08:08] <Darkside> they still need to make the damn things
[08:08] <Laurenceb_> haha
[08:08] <number10> lot of hyp so everyone wants one now
[08:08] <Laurenceb_> apparently Farnell site is intermittently down

[08:09] <Darkside> hrmm
[08:09] <Darkside> thats weird

[09:22] <Darkside> 1600GMT
[09:22] <fsphil> oh yea, late launch
[09:23] <Darkside> means means i cant track it :P
[09:23] <LazyLeopard> PM then. Right. I'll get on with the day. Not that that changes much.
[09:23] <LazyLeopard> ...but I can probably close the tracker page for now. :)

[09:24] <Hix> Where actually RS aren't selling till later in the week.
[09:26] <costyn> Hix: RP does'nt have much better info than the general public it seems about the inner workings of RS and Farnell. If you read the twitter feed you'll see they were surprised that RS was only selling friday and that RS is only selling to companies, not individuals (officially)

[10:02] <cuddykid> is it RM or parcel force over here?

[10:44] <upix> Hello, I have some questions concerning high altitude radio communications
[10:45] <upix> i was wondering how powerfull should the transmitter be
[10:45] <upix> for the high altitude baloon
[10:46] <number10> it depends on the country you live
[10:46] <upix> eastern europe
[10:46] <eroomde> ah Upu and _Hix, congratulations on your offspring
[10:46] <eroomde> you kept that one quiet
[10:46] <jonsowman> lol
[10:46] <number10> I am not from eastern europe upix so dont know
[10:47] <Hix> ?
[10:47] <eroomde> dnt worry :)
[10:47] <costyn> eroomde: hhehe
[10:47] <upix> should it be more or less the same around the globe. i was concerning signal strength
[10:48] <upix> should it be 25mW or 5W
[10:48] <eroomde> upix: what you're allowed to fly (in terms of radio power) depends on the laws in your country
[10:48] <costyn> upix: most people in the UKuse 10mW since that's the limit that is allowed. Also in the Netherlands 10mW is the max power
[10:48] <eroomde> in the UK we use 10mW
[10:48] <eroomde> as that is the most we are allowed
[10:48] <number10> worry on the 17th june if you get an unexpected card
[10:48] <eroomde> on 434MHz
[10:48] <x-f> upix, check out glory.lt, maybe Ernestas can help you
[10:48] <eroomde> and that works ok - people regularly get over 500km range with that
[10:49] <upix> ok, so 10mW should be enough then
[10:49] <costyn> upix: yes
[10:50] <costyn> Hix: eroomde meant that nick 'upix' seems like a combination of the nicks 'Upu' and 'Hix' :)

[10:52] woyna (woyna@79.133.200.48) joined #highaltitude.
[10:53] <upix> the other problem is how do you find a proper transmitter model. one that is not very expensive and works decent. I though of connecting GPS directly to radio transmitter, so it should be able to read UART too
[10:54] <costyn> upix: most people here use the radiometrix ntx2 but the rfm22b is a new alternative
[10:55] <costyn> upix: and you'll (probably) need a microcontroller to interface btween the gps and the radio
[10:55] <eroomde> upix: the reason for the microcontroller is that with only 10mW transmitter power, you have to slow the baud rate right down
[10:56] <eroomde> typically we use 50 or 300 baud RTTY
[10:56] <eroomde> so the microcontroller with get a position update from the gps, then spend about 10s transmitting it (along with any other info like battery voltages, temperature or whatever) to the ntx2 at the much lower baud rate
[10:57] <UpuWork> just read back lol eroomde

[11:01] <UpuWork> ok I'm not sure what the rules are there but generally over here we use the NTX2
[11:01] <UpuWork> do you have an amateur radio ?

[11:02] <upix> i dont
[11:02] <UpuWork> ok shame we could do with some your way to recieve balloons that float :)
[11:03] <upix> what do you mean?
[11:04] <number10> upix: x-f is from nearby Latvia he maybe able to help

[11:07] <upix> thanks
[11:07] <fsphil> upix, sometimes balloons are lost over eastern europe because there is nobody there tracking them.
[11:08] <upix> just like bermuda's
[11:08] <Hix> eroomde, shortly after he speaks to Ramsey http://www.youtube.com/watch?v=N8QfnEnf43w&feature=endscreen&NR=1
[11:09] <UpuWork> but yeah you'll need a GPs or some sorts
[11:09] <UpuWork> a radio
[11:09] <UpuWork> and microcontroller
[11:11] <upix> ok
[11:12] <upix> so basicly microcontoler just has to give out Vcc or 0 to NTX2 to send FM signal?
[11:12] <upix> or is there a protocol of any sort
[11:12] <UpuWork> we have a UKHAS protocol and basically we just adjust the voltage to the NTX2 slightly which adjusts the frequency
[11:13] <UpuWork> do it at the right timing and you have RTTY
[11:13] <UpuWork> http://ukhas.org.uk/communication:protocol
[11:13] <UpuWork> http://ukhas.org.uk/guides:linkingarduinotontx2
[11:14] <UpuWork> if you want a GPS there are some breakout boards on my store here : http://ava.upuaut.net/store
[11:15] <daveake> So, does Farnell's "Our websites are currently unavailable whilst we perform a scheduled system upgrade" mean "We did a deal to sell the Raspberry Pi and our server melted"?
[11:15] <UpuWork> roughly yes
[11:15] <UpuWork> I wonder how much they are loosing today
[11:15] <daveake> :)
[11:15] <UpuWork> one things for sure
[11:15] <daveake> Lots
[11:15] <UpuWork> I'm glad I'm not Farnell's IT department this morning
[11:15] <daveake> :D
[11:16] <daveake> It's been down for over 5 hours
[11:16] <daveake> The RS site faired slightly better
[11:17] <Hix> Farnell - it's really highlighting their tech cred.. he heh he
[11:18] <UpuWork> oh its working
[11:19] <Hix> for how long...
[11:19] <Hix> oj no it's dead again
[11:19] <Hix> clud cloud cloud
[11:20] <UpuWork> Well I have an order open for SBC, RASPBERRY PI, MODEL B
[11:20] <UpuWork> £26.55
[11:20] <SpeedEvil> Ok - logged in on farnell - with it in the basket
[11:20] <UpuWork> Further stock available in 30 days
[11:20] <SpeedEvil> Plus shipping :/
[11:20] <costyn> pff
[11:20] <costyn> farnell does free shipping doesn't it
[11:20] <Hix> UpuWork, that'll be your fat pipe
[11:21] <Hix> nope
[11:21] <SpeedEvil> odd
[11:21] <UpuWork> RS does free shipping
[11:21] <UpuWork> Farnell min order £20 and shipping
[11:21] <Hix> they don't have till Friday
[11:21] <UpuWork> they offset it by being slightly cheaper...no wait they don't
[11:21] <daveake> Upuwork I just get a "register your interest" page. Do you have the product code?
[11:21] <Hix> daveake, RS?
[11:21] <UpuWork> I closed it
[11:21] <SpeedEvil> There is just register on RS
[11:21] <UpuWork> and it doesn't work now
[11:22] <SpeedEvil> oh
[11:22] <daveake> Same on Farnell now

[11:23] <Hix> right shall we all start pre-ordering ipad 3's and see what we can crash next
[11:23] <daveake> Dead tho :p
[11:27] <PD3EM_work> UpuWork: How about your AVA2 hardware? Will that be available for order in the future?
[11:28] <UpuWork> no
[11:28] <PD3EM_work> UpuWork: thats a pitty... looks great
[11:28] <UpuWork> This is a bit of a mute point with people but I'm int he camp that says the flight computer is a rite of passage
[11:28] <UpuWork> if I make a HABduino
[11:28] <daveake> +1
[11:29] <UpuWork> it opens it up to anyone
[11:29] <UpuWork> they probably won't end up here and may not understand the implications of what they are doing and the safety aspects
[11:29] <UpuWork> so I'm not being awkward
[11:30] <PD3EM_work> understand that. HAB is no toy
[11:30] <UpuWork> However if you can prove to me you can make a board say on veroboard and just want to improve it but lack the PCB design skills/soldering skills come speak to me
[11:30] <UpuWork> but HABduino ? No. :)
[11:31] <Darkside> UpuWork: +1
[11:31] <PD3EM_work> I'll talk about it with a fellow ham
[11:35] <PD3EM_work> But on the other hand it would be good if complete (and standard) GPS/transmitter was available
[11:35] Jim3 (~JimBuk@host81-139-157-235.in-addr.btopenworld.com) joined #highaltitude.
[11:37] <upix> Just to clarify... RTTY is basicly UART (5bits and low bitrate)
[11:38] <upix> or is there a different i cannot see
[11:38] <Darkside> we don'tt use baudor
[11:38] <Darkside> baudot*
[11:38] <Darkside> well, often
[11:38] <Darkside> a lot of us use 7-bit ascii
[11:38] <daveake> But yes the waveform is like normal async serial
[11:39] <daveake> Baudot has this shift thing, and if the shift character is lost or corrupted you can't read the rest of the string
[11:39] Martin_100 (~Martin@78-105-240-247.zone3.bethere.co.uk) left irc: Read error: Connection reset by peer
[11:39] <daveake> So whilst it's a little quicker, it's a PITA
[11:40] Martin_100 (~Martin@78-105-240-247.zone3.bethere.co.uk) joined #highaltitude.
[11:41] <PD3EM_work> use spaces in baudot. It resets on every space and much less is lost
[11:41] <upix> 7 bits it is then :D
[11:42] <Darkside> using ascii also reduces code size on the embedded system
[11:42] <Darkside> depending on your hardware your entire transmit code can just be reduced to using the hardware UART
[11:43] <upix> how about the baudrate? eroomde mentioned 50 and 300bps
[11:43] <Darkside> yeah
[11:43] <Darkside> a lot of people use 50 baud
[11:44] <upix> do higher baud rates mess up in the air?
[11:44] <Darkside> well higher than 300 can be a bit unreliable
[11:44] <daveake> They mess up in the receiver in my case :(
[11:44] <Darkside> we use 300 baud on project horus launches
[11:44] <Darkside> but we have 3dB more signal than the UK guys do

[11:50] <upix> How about antenas. RTX connects to undirectional and receiver to directional? And what should the gain be of the antennas?
[11:51] <Darkside> uhh
[11:51] <Darkside> we use the NTX2s on the transmit side
[11:51] <Darkside> but on the receive side we use amateur radio sideband receivers
[11:52] <upix> oh i ment NTX2
[11:53] <Darkside> how do you mean?
[11:53] <Darkside> we usually use 1/4 wave antennas with ground radials on the payload
[11:55] <Hix> Just been looking and it appear that the adruino shield is 3.3v on the TTL serial side http://www.ladyada.net/make/gpsshield/modules.html
[11:55] <Hix> anyone advise?
[11:55] <Darkside> Hix: an AVR running at 5V can receive 3.3v TTL serial
[11:55] <zyp> upix, sender is omnidirectional because you don't know which direction the payload will point, but reciver may be directional because you know which direction the payload is in
[11:56] <upix> that's what i thought
[11:56] <upix> thanks
[11:56] <Darkside> Hix: don't use any of those gps modules
[11:56] Gillerire (~Jamie@219-90-243-82.ip.adam.com.au) left irc: Quit: Quit
[11:56] <Darkside> oh, except for the lassen IQ
[11:56] <Hix> Darkside, will it send at 5V though? I'm using upu's ublox breakout
[11:56] <Darkside> yeah, the arduino will send at 5v
[11:56] <Darkside> so you'll need to step the voltage down to 3.3v for the gps
[11:57] <Darkside> a voltage divider does that fine
[11:58] <Hix> so I need to use 3 voltage dividers one for power and 1 each for TX RX
[11:58] <Darkside> uhh
[11:58] <Darkside> no
[11:58] <upix> use voltage regulator for power
[11:58] <Darkside> yeah
[11:58] <Darkside> the TX from the GPS can go straight into the Arduino's RX
[11:58] <Darkside> but TX from the Arduino to GPS RX needs a voltage divider
[11:58] <UpuWork> Arduino supplies 3.3v
[11:59] <UpuWork> as well as 5V
[11:59] <Darkside> UpuWork: how much current can it supply
[11:59] Gillerire (~Jamie@219-90-243-82.ip.adam.com.au) joined #highaltitude.
[11:59] <UpuWork> good question not sure
[11:59] <Hix> 3.3V linear voltage regulator, 250mA current
[11:59] <Hix> is IC1 on board
[11:59] <UpuWork> DC Current for 3.3V Pin, 50 mA
[11:59] <UpuWork> ah yeah
[11:59] <UpuWork> don't use that
[12:00] <upix> What about this gps module: http://inventeksys.accountsupport.com/store/ISM300F2-C5-V0004.html is it decent?
[12:00] <UpuWork> yay
[12:00] <UpuWork> thats what I used originally
[12:01] <Darkside> heh
[12:01] <UpuWork> they are crap and slow to get lock

[12:01] <UpuWork> right lunch time
[12:01] <UpuWork> afk
[12:02] <upix> is that small antena enough?
[12:03] <Hix> http://www.ladyada.net/media/gpsshield/gpschemv11.png is schematic
[12:06] <Darkside> upix: when its in the air it'll be fine
[12:06] <Darkside> as long as you don't cover the payload in metal or something
[12:06] <upix> lol i thought of doing foil screening
[12:07] <Darkside> yeah dont do that around the GPS :P
[12:07] <Darkside> it doesn't work well :P
[12:07] <upix> roger that :D
[12:09] <upix> is there a cheaper way to receive signal without paying hundreds of ¬ for YAESU
[12:09] <Darkside> there are cheaper receivers
[12:09] <Darkside> well
[12:09] <Darkside> you can find other receivers secondhand
[12:10] <Darkside> Yaesu FT-790, Icom IC-R10, uhmmmm
[12:10] <Darkside> basically it needs to support SSB reception on 434MHz
[12:10] <eroomde> upix: the (old) Yeasu Ft790R is well liked around here
[12:11] <eroomde> it's much older than the current crop of radios but is just as sensitive
[12:11] <eroomde> it's a favourite starter radio for people here doing 434MHz balloons
[12:11] <upix> what about DIY receiver from NRX2
[12:11] Gillerire (~Jamie@219-90-243-82.ip.adam.com.au) left irc: Quit: Quit
[12:12] <eroomde> not nearly sensitive enough
[12:12] <Darkside> not sensitive enough
[12:12] <eroomde> doesn't do SSB
[12:12] <eroomde> wont work with fldigi therefore
[12:12] <Darkside> also the transmitter will drift with temperature
[12:12] <upix> wait NTX2 does SSB, but NRX2 doesnt?
[12:12] <Darkside> and you need to be able to track that
[12:12] <upix> shouldn't they be like a couple or transmiter and recceiver
[12:12] <Darkside> eroomde: don't we have a blog post somewhere about this
[12:13] <upix> of*
[12:13] <Darkside> wait i think i wrote one
[12:13] <Darkside> upix: hold
[12:13] <Darkside> i wrote something up about this
[12:13] craag_ (~ircconsol@thecraag.com) joined #highaltitude.
[12:13] <Darkside> http://rfhead.net/?p=36
[12:13] <Darkside> kind of
[12:14] <eroomde> upix: for short r5ange applications those will work as a matched pair
[12:14] <eroomde> what we're doing is far more extreme
[12:14] <Darkside> pretty much the TXD pin on the module is the input to a VCO
[12:14] <eroomde> so you need a much more sensitive receiver, with much better filtering and varible tuning, to receive
[12:14] <eroomde> trust us on this one
[12:14] <Darkside> by feeding in (biased and voltage divided) serial data, we're shifting the output frequency, producing FSK.
[12:15] <Darkside> and yeah
[12:15] <Darkside> the voltage dividing and biasing produces *narrowband* FSK - the narrower the bandwidth, the less SNR you need for a copy
[12:16] <daveake> Before I had a proper receiver, I faked SSB by connecting an NRX2 to the sweep input of a sig gen. Yes it did work.
[12:16] <Darkside> feeding, say, 3.3v logic levels into the NTX2s txd pin gives you FSK with about a 6KHz shift (i think), we use far smaller voltage shifts, resulting in about 400Hz of output frequency shift
[12:20] <upix> thanks

[13:26] <Lunar_LanderU> hi fsphil, how are you?
[13:26] <Randomskk> edmoore: http://www.flickr.com/photos/cuspaceflight/6793049100
[13:26] <Hix> farnell also have cpc.farnell.com

[13:27] <Lunar_LanderU> is wombat a new flight computer?
[13:28] <Randomskk> yes
[13:28] <Randomskk> hmm the photos post-reflow are not online
[13:28] <Randomskk> anyway I was up until 5am being sad. CUED is pretty empty at that time
[13:28] <Randomskk> most of that time was being sad at things that weren't problems, like the apparent short between gps rf in and gnd (actually a shunt in the lna)
[13:29] <edmoore> It looks v pretty
[13:29] <Randomskk> but also the 3v3 supply is being weird and drawing tons of current and I can't figure out why, which is an issue
[13:29] <edmoore> Good connector choice
[13:29] <fsphil> don't worry, be happy
[13:29] <Randomskk> I hope that was sarcasm
[13:29] <Randomskk> the middle connector couldn't take reflowing
[13:29] <Randomskk> it failed amazingly
[13:29] <Randomskk> put a new one on by hand
[13:29] <edmoore> I am about to purchase the picoblade Crimper
[13:29] <Randomskk> the jtag connector is nice though
[13:29] <Randomskk> anyway the GPS works and gets a lock in my room
[13:29] <Randomskk> the ARM responds to the bootloader but won't be bootloaded
[13:29] <edmoore> Ok excellent
[13:29] <Randomskk> which is a total pain
[13:29] <edmoore> Gem
[13:30] <edmoore> Hrm*
[13:30] <Randomskk> and starts to talk over USB, but won't enumerate
[13:30] <Randomskk> and I left my jtag dongle at cued, so couldn't jtag it last night
[13:30] <Randomskk> so something may be up with it but I can't tell what
[13:30] <Randomskk> which is very frustrating
[13:30] <Randomskk> so also can't test the adf
[13:30] <edmoore> Ftdi. USB be dragons
[13:30] <Randomskk> I have both
[13:30] <Randomskk> neither are working
[13:30] <edmoore> Ouch
[13:30] <Randomskk> crucially this all means there's pretty much no way it will launch today
[13:31] <Randomskk> I was hoping to get hardware done by midnight so I could spend the subsequent five hours programming it
[13:31] <edmoore> I am expecting similar woe when I get mine back on Monday
[13:31] <Randomskk> at least your woe won't be exaggerated by everything being 0402, or the only two apparent hardware issues being on the two devices where the pads are under the device
[13:33] <edmoore> Welcome to my world, badger2 summer2009
[13:34] <edmoore> Also issues inside internal layers for added sexy funtime
[13:34] <Randomskk> yea
[13:34] <Randomskk> so far I haven't found any serious board issues
[13:35] <Randomskk> only that the six pin smd header I used has the pins alternate the other way
[13:35] <Randomskk> so I had to bend them all back
[13:35] <Randomskk> which is really annoying
[13:35] <Randomskk> espeecially as it's the largest pitch part on the board
[13:35] <Randomskk> all the footprints fit and I've not found any dodgy routing yet though
[13:35] <Randomskk> so that's somethin
[13:35] <zyp> :)
[13:35] <Randomskk> oh, the cutout in the board for the antenna is the wrong side, so I had to remove the key from the antenna thing
[13:36] <edmoore> Oh what?
[13:36] <Randomskk> see the notch in the top right?
[13:36] <edmoore> Which library did you use?
[13:36] <Randomskk> none
[13:36] <Randomskk> all my own parts
[13:36] <zyp> that board looks familiar
[13:36] <edmoore> Oh wait not eagle
[13:36] <edmoore> Phew
[13:37] <Randomskk> :P
[13:37] <Randomskk> zyp: to the one I was pasting designs for earlier?
[13:37] <edmoore> Was worried that might have got me too
[13:37] <zyp> yep
[13:37] <Randomskk> also at one point last night I snagged the antenna in a cable and it snapped off
[13:37] <Randomskk> taking the rf and one gnd pin with it
[13:37] <Randomskk> which made me very very very sad
[13:37] <griffonbot> Received email: Priyesh Patel "Re: [UKHAS] Re: Apex III Launch 1 Announcement"
[13:37] <Randomskk> so I managed to somehow get that back on using tiny pieces of metal soldered into place
[13:38] <zyp> Randomskk, you're acting faster than me :p
[13:38] <Randomskk> and 0.2mm worth of exposed rf trace
[13:38] <Randomskk> then epoxied the hell out of it
[13:38] <Randomskk> which is what I should have done to start with
[13:38] <Randomskk> mainly right now though I want to know why my smps doesn't work
[13:38] <Randomskk> or rather, it does work, but draws like 1A and dissipates it
[13:38] <Randomskk> so gets v hot
[13:38] <priyesh> just a note to those tracking today - the packet structure is now 2x300 for each packet and then 1x50 on every fifth packet
[13:39] <edmoore> That's why I used a pth08080 for my smps for 0.1
[13:40] <edmoore> That and I can route underneath it
[13:40] <Randomskk> meh
[13:40] <Randomskk> I just found a cap that appears to be a dc short
[13:40] <Randomskk> so I guess that could be it
[13:40] <Randomskk> will rework it later
[13:40] <Randomskk> on the plus side I learnt how to use the hot air gun to rework parts
[13:40] <Randomskk> on the down side, the screw terminals did not agree with hot air
[13:40] <Randomskk> but it now has a reworked smps chip and lna chip
[13:40] <Randomskk> cry
[13:41] <Randomskk> wait
[13:41] <Randomskk> wtf
[13:41] <Randomskk> I didn't have a shorted cap at all
[13:41] <Randomskk> oh god
[13:41] <Randomskk> I think when I reworked the smps chip, two caps changed orientation
[13:41] <Randomskk> oh god
[13:41] <Randomskk> yea they totally did
[13:41] <Randomskk> oh ffs
[13:41] <Randomskk> well at least I know what to fix now
[13:41] <Randomskk> sadly I also have to run to a meeting now and then it's launch time, so
[13:42] <SpeedEvil> Argh.
[13:42] <Randomskk> 0402s will go friggin anywhere
[13:42] <Randomskk> also tombstone
[13:42] <Randomskk> so annoying
[13:42] <edmoore> :)
[13:42] <zyp> true
[13:42] <edmoore> Even in the oven?
[13:42] <Randomskk> note to self, never put gnd vias in pads again
[13:42] <zyp> that's why I went with 0603 for my last board
[13:42] <edmoore> Or just manually?
[13:42] <zyp> edmoore, yes
[13:42] <Randomskk> edmoore: both
[13:42] <Randomskk> 4 tombstoned in the oven
[13:43] <Randomskk> and were then very annoying to replace
[13:43] <Randomskk> re-place
[13:43] <edmoore> I never put vias in pads anymore
[13:43] <edmoore> It's never worth it
[13:43] <Randomskk> I don't think I will again :P
[13:43] <Randomskk> well it does give the lowest impedance path to ground
[13:43] <zyp> edmoore, one side melts slightly earlier than the other side, and then it gets pulled straight over to the melted side
[13:43] <Randomskk> which is meant to be good for rf filters etc
[13:45] <zyp> never put gnd vias in pads, unless it's for thermal purposes
[13:45] <Randomskk> about 90% of my gnd vias in pads worked fine
[13:45] <Randomskk> but they make reworking a total pain
[13:45] <zyp> yes, that's exactly it

[14:28] <cuddykid> thanks for the recommendation Hix
[14:28] <costyn> yea 40 euro for Farnell and RS 27 euro here in NL
[14:28] <Hix> Cool - Farnell can do one
[14:29] <Hix> I'll just ebay it for £95
[14:29] <costyn> shipping is free though for Farnell here in NL. RS I'm not sure
[14:30] <Hix> Farnell add it to their inflated costs so it appears free. RS add shipping unless you have account

[14:32] <Laurenceb> RS have them in stock?

[15:44] <fsphil> yea
[15:44] <PD3EM> it would have been great if I could select left-right in dl-fldigi so I could decode both at the same time
[15:44] <fsphil> do you have two sound cards?
[15:44] <cuddykid> run time - then APEX time!
[15:44] <fsphil> if so you can run both at the same time
[15:44] <cuddykid> should be an interesting flight

[16:48] <eroomde> hi dl4xav
[16:48] <eroomde> ApexLab_: ok good luck
[16:48] <eroomde> having the balloon inflated without a gps lock is a mjaor pain
[16:48] <eroomde> major*
[16:49] <Randomskk> definitely wanna get gps lock before inflating
[16:49] <Randomskk> :( I still can't figure out what's wrong with this
[16:49] <Randomskk> if I apply 3v3 direct to that net, it only draws like 100mA as expected
[16:49] <cuddykid> back
[16:49] <fsphil> regulator pinout different than expected?
[16:49] <Randomskk> if I apply 3v3 to the input of the smps, it draws whatever I have the current limit set to, right up to 600mA
[16:49] <cuddykid> what's going on?
[16:49] <Randomskk> if I just connct a battery up to the smps, it does provide 3v3 output
[16:50] <Randomskk> but I don't know (and dread to think) how much current it draws - it gets really really hot
[16:50] <eroomde> inflation should really be the very last thing you do, once evrything else is completely assembled and working
[16:50] <cuddykid> indeed eroomde :P
[16:50] <eroomde> cos going back is expensive
[16:50] <eroomde> Randomskk: what's the load on it?
[16:51] <cuddykid> it'll be dark by the time it lands - buzzer present?
[16:51] <Randomskk> eroomde: stm32, ublox 6, adf7012 not transmitting
[16:51] <Randomskk> total circa 100mA or something
[16:51] <Randomskk> it should be totally able to handle it
[16:51] <eroomde> okk
[16:51] <Randomskk> I don't get why it just keeps drawing more and more current
[16:51] <eroomde> that's fine then, it shouldn't be a load issue
[16:51] <ApexLab_> News from lauch site: tying up balloon, should be away in the next 10-15 mins
[16:51] <cuddykid> nice
[16:51] <eroomde> sometimes with very low loads they go a bit unstable
[16:52] <cuddykid> this will be an interesting flight
[16:52] <Randomskk> I found a few micro bridges on the stm32 pins
[16:52] <Randomskk> right at the back and too small to see without a microscope
[16:52] <Randomskk> total pain
[16:52] <nigelvh> Just let it draw a few amps. It'll eventually blow out the bridges.
[16:53] <Randomskk> :|
[16:53] <Randomskk> in theory it has internal overcurrent and overtemp protection
[16:53] <Randomskk> but this morning I smoked one <:/
[16:53] <Randomskk> also the overcurrent is 1500mA
[16:53] <Randomskk> which I haven't tried providing tbh
[16:53] <nigelvh> Bah, who needs that crap. Just use a big fat zener diode regulator. Efficiency is for losers.

[17:28] <Hix> later the better for me
[17:28] <cuddykid> sms based
[17:28] <ApexLab__> Not sure exactly. Think its being unstable. they keep getting lock then losing it i think. Thanks for all the support so far guys
[17:29] <eroomde> emi?

[17:30] <cuddykid> backup would be fairly critical to finding it in the dark aswell - unless you're right on the balloons tail

[17:33] <ApexLab__> i think we attempted it before but im not sure we did this time. we attached some loud sirens to it to allow us to find it in the dark

[17:55] <ApexLab__> 434.650 but i think it might be lower due to drift. anyone have freq?
[17:55] <G0DJA> The blurb said 434.650 so I guess 434.649 + 1000Hz
[17:55] <MLow> thats not a ham freq...

[17:56] <daveake> I was going to take kit to track from the car on the way home, but didn't :)

[18:00] <G0DJA> nigelvh it's only a secondary Ham freq - 434 is home to loads of low power devices as well

[18:04] <Upu> 300 baud not quite decoding but 50 is fine
[18:04] <cuddykid> oh - I've just seen your call sign on the "receivers"

[18:05] <cuddykid> haha
[18:05] <nigelvh> G0DJA, I'm aware it's a ham frequency, MLow-werk seemed to imply it wasn't
[18:05] <cuddykid> mines bad - I never have my receiver with me

[18:05] <Hix> spacenear showing sploshdown
[18:05] <futurity> but to double check you are seeing my data uploaded?
[18:06] <daveake> Hint for those who forgot (like me till just now) you can run dl-fldigi twice, once for each baud rate
[18:06] <cuddykid> my money is on splashdown with 2ms ascent rate lol
[18:06] <MLow-werk> 433.00-435.00 Auxiliary/repeater links
[18:06] <MLow-werk> My bad
[18:06] <OZ1SKY_Brian> ApexLab__ what are the light indicators?
[18:06] <CovBalloon> would be quite amusing if it landed inside Norwich Prison
[18:06] <MLow-werk> This is pretty classic case of Auxiliary use of ham
[18:06] <cuddykid> we should have stakes/bets on where it's going to land haha
[18:06] <ApexLab__> sorry, dont know exactly. didnt know we had any
[18:07] <MLow-werk> is that band lincense excempt in europe?
[18:07] <OZ1SKY_Brian> ApexLab__ ok, hope to hear it over here
[18:07] <cuddykid> jeez - is the ascent rate really 2ms?! - another floater?!
[18:07] <MLow-werk> because i thought ham use was banned in airspace
[18:07] <Hix> 2.2m/s floaty?
[18:07] <fsphil> MLow-werk, license exempt yea
[18:07] <cuddykid> very floaty
[18:07] <fsphil> it's not being used as an amateur device
[18:07] <nigelvh> For those in the UK. Here in the US ham in the air is fine.
[18:07] <MLow-werk> well it's not 5m/s but i wouldnt call that a floater
[18:07] <OZ1SKY_Brian> ApexLab__ your welcome to land over here :-)
[18:07] <cuddykid> nigelvh: you're lucky :P
[18:07] <craag_> Just wondering, who are tracking from the lanchester building in soton?
[18:08] <LazyLeopard> Hmmm... Looks like the weird steps in the altitude graph correspond to the 50 baud lines...
[18:08] <gonzo_> that bit of 70cm is licence exempt too, key bobs etc
[18:08] <gonzo_> fobs
[18:08] <G0DJA> MLow-werk 70cm isn't an exclusive Ham band - this is authorised in the ISM part of the band
[18:08] <cuddykid> MLow-werk - usually <= 3ms is floaty terriotry
[18:08] <cuddykid>
[18:08] <nigelvh> Yes, 433.92 +/- is common part 15 stuff.
[18:09] <OZ1SKY_Brian> anyone hearing the 27.12 beacon ?
[18:09] <cuddykid> ApexLab__: what balloon is being used?
[18:09] <nigelvh> I've got some little 500mw transmitters there, and all the cars and whatnot start sending back chirps because they don't understand my signals.
[18:10] <ApexLab__> totex but cant remember exactly what weight. might be 2000 but not totally sure

[18:10] <G0DJA> Too much other stuff near the 434MHz frew to get a decode at the moment
[18:10] <cuddykid> ApexLab__: ahh ok, good thing it's not the floaty hwoyees
[18:11] <nigelvh> The FRS stuff is up 460ish
[18:11] <MLow-werk> ah 462-467, nvm
[18:11] <MLow-werk> beat ya to google ;)
[18:11] <G0DJA> Nothing on 27.12 here as yet
[18:11] <MLow-werk> Interesting, never played with 70cm
[18:11] <nigelvh> Except I knew it off my head
[18:11] <MLow-werk> No, you just have google cached in your head
[18:11] <OZ1SKY_Brian> MLow-werk 462 and 467, not 462-467 :-)
[18:11] <nigelvh> Or wikipedia
[18:11] <Upu> very good signal btw
[18:12] <MLow-werk> I had the day off yesterday, what did I do? Slept til 5pm and got up and ate a tub of icecream
[18:12] <futurity> Does space near.us only display one of the receivers these days? I've yet to receive a bad row, yet I don't seem to be listed very often
[18:12] <Hix> jonsowman, are you delivering Timzaman payload back to him via HAB?
[18:12] <MLow-werk> got 0 work done on my project
[18:12] <OZ1SKY_Brian> G0DJA let us know if you hear it, should be a better OTH, but depends on the antenna
[18:12] <nigelvh> Nice job, I'm proud of you MLow
[18:12] <ApexLab__> what frequency has it currently settled on?
[18:13] <futurity> 434.651
[18:13] <MLow-werk> To be fair it felt like I had rocks in my stomach and a stick in my foot
[18:13] <G0DJA> OZ1SKY_Brian OK will concentrate on the 11m freq as 70cm too noisy with another signal for decode
[18:13] <nigelvh> Probably had nothing to do with eating a tub of ice cream.
[18:14] <Upu> spacenear.us only showing 1 tracker at once for everyone or jus tme ?

[18:26] <daveake> hear*
[18:26] <LazyLeopard> futurity: I think it has to do with the numbers of packets coming in. At 50 baud I'm only seeing every fifth, so in between the lines I get tagged for there are 4 others for others to get, and I guess some lines are being sent twice, too, which probably adds to the confusion...

[18:32] <G0DJA> I did Brian but as I'm on 50 Baud for best decode it messes up the settings...
[18:32] <cuddykid> junderwood_M0JCU: with plenty of fuel I hope.. lol
[18:32] <Upu> G0DJA are you getting silly figures in the distance ?
[18:33] <G0DJA> Upu yes 575020.5
[18:34] <jcoxon> It's because the Lat lon are nmea rather than dd.ddd
[18:34] <G0DJA> AH!
[18:34] <jcoxon> So dlfldigi doesn't calc it right
[18:34] <G0DJA> 50 baud seems more reliable here
[18:34] <jcoxon> Well fix that one day
[18:34] <Upu> ah ok
[18:35] <LazyLeopard> Even 50 didn't get through just now...
[18:35] <DanielRichman> dlfldigi appears to have code to fix ddmm.mm; does it not work jcoxon ?
[18:35] <ApexLab__> i agree 50 is more reliable tonight
[18:35] <Upu> getting some noise here
[18:35] <cuddykid> wow, ascent rate has jumped to near 5?!
[18:35] <nigelvh> Yeah, the updated path looks a lot better.
[18:36] <cuddykid> yep
[18:36] <jcoxon> Oh perhaps, I thought we hadn't fixed it yet
[18:36] <cuddykid> why the sudden jump?
[18:36] <jcoxon> Clouds?
[18:36] <cuddykid> oh - it's come back down
[18:36] <LazyLeopard> Hmm... Prediction nearer dry land...
[18:36] <cuddykid> jcoxon: oh, I suppose - but that's quite a big difference
[18:36] <nigelvh> Damn.
[18:37] <cuddykid> no more LazyLeopard :S
[18:37] <cuddykid> we can only hope that as it ascends above clouds it speeds up
[18:37] <LazyLeopard> Oops
[18:37] <G0DJA> Major fadeing that time
[18:40] <G0DJA> 300baud decodes at times but seems less secure than 50 baud here

[18:40] <Upu> if you're getting silly distances click DL Client -> Configure -> Payload and check NMEA , fixes it, I had to uncheck it save, then recheck it save for it to work
[18:40] <Graham_G3VZV> find some fish and chips maybe?
[18:41] <gonzo_> while they wait for the tide to return it?
[18:41] <cuddykid> lol
[18:41] <daveake> These are good plans :)
[18:41] <Upu> 434.651.060 now
[18:41] <cuddykid> I'm off to get fish and chips in a sec :P
[18:41] <costyn> did they do a Tim and not measure the neck lift? :)
[18:41] <jonsowman> costyn: we measured neck lift very carefully
[18:41] <jonsowman> but we didn't have a final payload mass
[18:41] <jonsowman> so i think the error is more likely to be there
[18:42] <jonsowman> ascent rate should have been 4.5m/s
[18:42] <cuddykid> should've just pumped all the helium you had in :D
[18:42] <daveake> That's what I did
[18:42] <jonsowman> cuddykid: haha i think that would have been a bit too much
[18:42] <jonsowman> since it was a 9.something cubic metre cylinder
[18:42] <daveake> But it was still a fish&chip flight

[18:43] <gonzo_> bacon butties at take off, chippie at recovery. Then beer
[18:43] <cuddykid> that's what I like with the Worcester launch site - usually it drifts east, so unless the ascent is really badly wrong then it's usually fine
[18:43] <daveake> So postie decided to use the cat flap instead of the letter box ...
[18:43] <jonsowman> costyn: yep, let's see what happens. i'm back at home with a cup of tea watching on spacenear...

[18:59] <jcoxon> Well old float flights were Totex, sure they were pinholes but we theorized that the hole might not be needed
[19:00] <jcoxon> The key was sunset
[19:00] Action: Upu_2E0UPU looks out of the window
[19:00] <Upu_2E0UPU> check
[19:00] <Dan-K2VOL> yeah, the Totex/Kaymont/Kaysam balloons have a very low burst pressure
[19:00] <Dan-K2VOL> so to avoid burst, you must lower the helium pressure
[19:01] <Dan-K2VOL> through venting or temperature reduction
[19:01] <jcoxon> Certainly we saw similar float characteristics in non pinhole 3kg
[19:01] <SpeedEvil> The greater the neck lift, the more a balloon with a given amount of gas is 'pushed' up, when the rubber starts to strain, not yield.
[19:02] <Dutch-Mill> Evening all whats the exact frequency?
[19:02] <Upu_2E0UPU> 434.651.06 here

[19:09] <jonsowman> could you drop the asc rate a bit please?
[19:09] <junderwood_M0JCU> With the predicted burst point, descent would have to be supersonic to avoid the drink

[19:32] <priyesh> housing leads to condensation...
[19:32] <Dan-K2VOL> priyesh, if you properly dehumidify the housing, you get no condensation. The GOPRO manual explains how to do this
[19:33] <Dan-K2VOL> (by putting dessicant water absorber packs inthe closed housing for a few hours before use)

[19:34] <priyesh> Dan-K2VOL: we were considering that - but decided not too..
[19:34] <Dan-K2VOL> better safe than sorry, if you can't cold test to find out if your procedure works
[19:34] <Dan-K2VOL> dry ice testing of everything is a good idea though, and available cheaply in the US and UK, that I know of
[19:35] <costyn> nigelvh: thx for the carbon fiber reply last night. i was going to put my antenna in a little ABS tube, but when i got to the hobby shop they had sold out, so I saw a nice carbon fiber tube and bought that instead, only later realizing that it probably wouldn't work
[19:35] <costyn> Dan-K2VOL: ah yes, good idea
[19:35] <costyn> Dan-K2VOL: more convenient and safer than trying to stuff it in your freezer
[19:35] <nigelvh> Yeah. We run into that for our rockets. They're always wanting to make the tubes carbon fiber, and myself and the other telem guy keep saying no.
[19:36] <Dan-K2VOL> costyn, also about 50C colder than your freezer!
[19:36] <costyn> Dan-K2VOL: yes, much more representative

[19:39] <nigelvh> costyn: I don't have the numbers in front of me, but we used a signal generator with an antenna inside a carbon fiber tube, and a spectrum analyzer with a receive antenna across the garage. It did make a significant difference. Though at frequencies below 70cm, possibly workable if you have large signal margins.
[19:40] <gonzo_> wow, A DECODE!
[19:40] <costyn> nigelvh: well I'll be using the standard 434 MHz, so will be looking for something else to put the antenna in
[19:40] <nigelvh> Good plan.
[19:40] <PD3EM_shack> still no good decode here http://yfrog.com/mnzniufj

[19:41] <Dan-K2VOL> would be interesting for the tracker to optionally show the original launch prediction, so you could see the amount of deviation from prediction
[19:42] <junderwood_M0JCU> PD3EM, your audio level into fldigi looks quite high
[19:42] <junderwood_M0JCU> try turning the mic level down a little (and turn off AFC)
[19:43] <fsphil-laptop> got a hint of a signal maybe
[19:43] <OZ1SKY_Brian> is it REV rtty ?

[21:03] <Laurenceb_> they have floated before

[21:04] <danielsaul> Once we got the GPS sorted we just wanted to get it in the air... We really shouldnt have
[21:04] <RocketBoy> what balloon is it?
[21:04] <cuddykid> totex
[21:05] <Dan-K2VOL> I'm not sure that a resistor is a valid test of solar panel output though
[21:05] <jonsowman> RocketBoy: totex 1500
[21:05] <Dan-K2VOL> or is it the ideal test
[21:05] <Dan-K2VOL> I know it's not a good test for constant current drain on battery life
[21:05] <RocketBoy> yeah - unlikly to float unless its a very light payload
[21:06] <nigelvh> Youre unlikely to get the max power point.
[21:06] <MLow> for those that tuned into my car troubled, 240mi in and it looks strong, im driving to houston over the weekend, so i checked the fluids and it's a bit high on atf so im going to pump a bit out
[21:06] <Dan-K2VOL> RocketBoy - I beg to qualify that - "with a latex balloon" :-P
[21:06] <RocketBoy> well I mean a totex 1500
[21:06] <Dan-K2VOL> we do intend our 5 kilo box o'batterys to float
[21:06] <cuddykid> nah, it's not max power - but the "max" power did lie somewhere around 150/200ohm, and I took readings of 150 and 200ohm
[21:07] <cuddykid> interesting - this flight is heading more south than planned
[21:07] upix (4e3c1ef4@gateway/web/freenode/ip.78.60.30.244) joined #highaltitude.
[21:07] <cuddykid> much more south
[21:07] <RocketBoy> now if it was hwoyee1600 then I'd say it was likely to float
[21:07] <upix> hello
[21:08] <RocketBoy> with a 2.5m/sec ascent rte
[21:09] <OZ1SKY_Brian> whats is the current freq, should be here any time now?
[21:09] <number10_2E0DBR> 434.647
[21:09] <OZ1SKY_Brian> thanks
[21:10] <jonsowman> oh it's turning...

[21:10] <cuddykid> dow :(
[21:10] <Upu_2E0UPU> its off to see Brian!
[21:10] <cuddykid> yeah
[21:11] <cuddykid> homing balloon
[21:11] <Upu_2E0UPU> free gopro if you can catch it Brian
[21:11] <cuddykid> let's just say it burst now and landed on land - it still probably wouldn't be able to be recovered as there is no sms backup and no one near enough to follow it down?
[21:12] <OZ1SKY_Brian> Upu_2E0UPU no no return of it free of charge if it lands here :-)
[21:12] <cuddykid> it's accelerating (horizontal speed)
[21:12] <Upu_2E0UPU> well fingers crossed
[21:12] <Upu_2E0UPU> accent rate is slowing
[21:12] <cuddykid> float time :P
[21:12] <Upu_2E0UPU> this isn't a chinese balloon
[21:13] <Upu_2E0UPU> so they aren't meant to float but jcoxon says its possible under certain circumstances
[21:13] <cuddykid> it still may have picked up mysterious chinese magic dust
[21:13] <Upu_2E0UPU> Dan-K2VOL may be able to shed some light too
[21:13] <fsphil_2I0VIM> burst time
[21:13] <Upu_2E0UPU> its burst
[21:13] <Upu_2E0UPU> ?
[21:13] <cuddykid> no
[21:13] <NigeyS> ill get my bow and arrow phil :p
[21:13] <fsphil_2I0VIM> not yet, but I think it's going to shortly
[21:14] <OZ1SKY_Brian> fsphil stop saying that, its so close now :-)
[21:14] <fsphil_2I0VIM> lol
[21:14] <cuddykid> is there anyone around to track it down?
[21:14] <Laurenceb_> seems to be levelling out
[21:14] <Laurenceb_> looks like float
[21:14] <Laurenceb_> or will it burst first
[21:14] <fsphil_2I0VIM> mine did this :)
[21:14] <cuddykid> place your bets now people
[21:14] <OZ1SKY_Brian> still no trace on the waterfall, must be pretty close to a weak trace
[21:14] <fsphil_2I0VIM> I think it'll burst in the next 5 minutes
[21:14] <Upu_2E0UPU> still landing in the sea
[21:14] <Upu_2E0UPU> http://habhub.org/predict/#!/uuid=e00a191c701ce50ae2dbf6e15b1c220bffa1d24b
[21:15] <number10_2E0DBR> 25p says the gopro is lost
[21:15] <RocketBoy> gopro -ohno
[21:15] <Upu_2E0UPU> oh yes :/
[21:15] <cuddykid> I'm going for a few mins max of float, burst around 32km
[21:16] <cuddykid> oh, it's heading north east now :S - the winds tonight are really messed up!
[21:16] <upix> what do you mean by float? the baloon doesnt burst at all?
[21:16] <Dan-K2VOL> upu cuddykid well I know bill brown has floated a few latex accidentally without pinholes
[21:16] <fsphil_2I0VIM> ascent rate is oscillating
[21:16] <RocketBoy> BTW did timz get his payload back?
[21:16] <Dan-K2VOL> before the hwyoee era
[21:16] <Upu_2E0UPU> yes he did RocketBoy
[21:16] nosebleedkt (~nosebleed@ppp046177004066.dsl.hol.gr) joined #highaltitude.
[21:16] <OZ1SKY_Brian> float to osnabrück, DL :-)
[21:16] <fsphil_2I0VIM> RocketBoy, shockingly yes
[21:16] nosebleedkt (~nosebleed@ppp046177004066.dsl.hol.gr) left irc: Client Quit
[21:16] <RocketBoy> good show
[21:16] <cuddykid> nice Dan-K2VOL
[21:16] <Upu_2E0UPU> upix the ballons doesn't burst , it doesn't go up or down
[21:16] <Upu_2E0UPU> just carries in the winds
[21:16] <Upu_2E0UPU> will burst eventually
[21:16] <Upu_2E0UPU> latex degrades
[21:16] <upix> why does this hapen
[21:17] <Dan-K2VOL> physics my friend upix
[21:17] Action: fsphil_2I0VIM braces :)
[21:17] <Upu_2E0UPU> yeah I'll let Dan have that question
[21:17] <Dan-K2VOL> the balloon reaches neutral bouyancy, similar to how submarines and fish do it
[21:17] <fsphil_2I0VIM> 30km!
[21:17] <Dan-K2VOL> where the lift force reduces gradually until it is equal to the weight force
[21:17] <upix> so at 30+ km there's no boyancy?
[21:17] <OZ1SKY_Brian> dont get it, should be able to get a weak trace now
[21:18] <Dan-K2VOL> and that means vertical motion will stop (or close to it)
[21:18] <cuddykid> boom!
[21:18] <fsphil_2I0VIM> OZ1SKY_Brian, yea I'm struggling with this one to
[21:18] <fsphil_2I0VIM> too
[21:18] <Upu_2E0UPU> its not that clear for me either
[21:18] <cuddykid> horizontal speed has picked up a fair bit
[21:18] <Upu_2E0UPU> antenna possibly ?
[21:18] <Dan-K2VOL> However, for lift force to reduce to be equal to weight force, you have to change your mass to balloon volume ratio
[21:18] <fsphil_2I0VIM> the antenna must be putting more power towards the ground than the horizon
[21:19] <SpeedEvil> upix: In short - the balloon ascends at a linear speed as long as you can neglect the differential pressure due to the membrane.
[21:19] <G8NSV> yep been watching the speed
[21:19] <Dan-K2VOL> normally the latex balloons will keep expanding as they climb, increasing volume in pace with the decreasing air pressure, which results in practically a constant lift force, until the balloon rips open from being stretched too far
[21:20] <Hix> Night flights seem nice and warm -46
[21:20] <Dan-K2VOL> So to stop your climb, you need to stop increasing in volume
[21:20] <SpeedEvil> upix: However, in some cases, you can't. If the differential pressure due to the balloon causes the gas inside to become denser - you lose lift. If the lift drops to zero before teh stress in the balloon envelope reaches bursting point - you float
[21:21] <Upu_2E0UPU> you ok there upix ? :)
[21:21] <upix> yes
[21:21] <Hix> :D
[21:21] <Upu_2E0UPU> ask the meaning of life next time might be simpler
[21:21] <Dan-K2VOL> upix: which you can do by either letting the helium out, or having the rubber reach a point where instead of stretching more as the air pressure drops, it reaches a stiff restraint state - sort of like elastic in clothes will only stretch until the strong cloth stops it
[21:21] <NigeyS> lol
[21:21] <Dan-K2VOL> haha
[21:22] <Upu_2E0UPU> Dan-K2VOL did a great presentation at the UKHAS conference on it
[21:22] <Dan-K2VOL> the stiffening is what I assume happens with the hwoyee balloons, due to some recent flights
[21:22] <Upu_2E0UPU> http://www.youtube.com/watch?v=jtfJuTvaHxo
[21:22] <Hix> Is that what totex do then?
[21:22] <Dan-K2VOL> thanks upu
[21:22] <upix> oh btw Upu_2E0UPU i wanted to ask what are the shipping costs
[21:23] <Dan-K2VOL> totex don't seem to be able to stiffen
[21:23] <Upu_2E0UPU> Latvia ?
[21:23] <Dan-K2VOL> you need to reduce the helium pressure somehow with those, it would seem
[21:23] <upix> lithuania
[21:23] <jonsowman> 5 miles to the coast
[21:23] <Dan-K2VOL> hix by venting, or reducing temperature inside the balloon
[21:23] <upix> but i think its the same
[21:23] <SpeedEvil> And if they can't 'stiffen' - then you can't stabilise the altitude
[21:23] <Dan-K2VOL> hix, which you can do by setting the sun
[21:23] <fsphil_2I0VIM> my prediction of imminent burst seems to have been wrong
[21:23] <Upu_2E0UPU> Yeah I think its about £7.92 UK pounds for signed not a massive amount
[21:23] <Dan-K2VOL> the totex don't last long if they do floay, speedevil is right
[21:23] <SpeedEvil> You can change the ascent rate once using gas release.
[21:24] <Upu_2E0UPU> if you put stuff on the order there is a calculate shipping costs option
[21:24] <SpeedEvil> But then if you get a negative ascent rate - you're going down.
[21:24] <Upu_2E0UPU> before you buy
[21:24] <Hix> Dan-K2VOL, what librart do you use in Arduino or c++ to setSun? :p
[21:24] <cuddykid> now this is where the glider that's being built would come in extremely handy! :D
[21:24] <upix> thanks Upu_2E0UPU
[21:24] <cuddykid> cutdown, and fly it straight back to cambridge :)
[21:24] <Dan-K2VOL> haha hix, something like LibPlanetMove
[21:25] <cuddykid> nice evening flight then
[21:25] <fsphil_2I0VIM> I'd need libmovehorizon to receive this one
[21:25] TYKE (~mce@78-105-240-247.zone3.bethere.co.uk) left irc: Quit: Leaving
[21:25] <OZ1SKY_Brian> im thinking burst just as i get the first signal on the waterfall
[21:26] <fsphil_2I0VIM> 1m/s
[21:26] <jonsowman> OZ1SKY_Brian: probably :D
[21:26] <NigeyS> fsphil_2I0VIM, you think you can compile that with libneedmorealtitude1.0 to ?
[21:26] <Hix> no, got it setRotAngleAroundSun {270};
[21:26] <Dan-K2VOL> ahh good hix
[21:26] <OZ1SKY_Brian> i tryed that a few times before, weak waterfall and no decode, pop
[21:27] <Dan-K2VOL> Arduino 1.0 broke all of those libraries though, so you'll have to do it all in universe assembly
[21:27] <Upu_2E0UPU> oh Dan-K2VOL don't know if I showed you this but the one on the right is the uBLOX MAX6 + Antenna, without the header it weighs 1.5g : http://i.imgur.com/guCVX.jpg
[21:28] <Hix> hmm, goes to find galaxy2.3.4 ref manual
[21:28] <fsphil_2I0VIM> my last flight accidentally divided by zero and caused a black hole at the center of the sun
[21:28] <futurity> ascent slowing :)
[21:28] <Dan-K2VOL> hha fsphil ,I was wondering why my solar panels were sucking so much power
[21:28] <fsphil_2I0VIM> sorry about that, will be fixed in the next version :)
[21:28] <Dan-K2VOL> upu WHAT? 1.6g as in grams?
[21:28] <Upu_2E0UPU> thats technically a float
[21:28] <Hix> people done night flights much before?
[21:29] <Upu_2E0UPU> 1.5g in total for the GPS + Antenna
[21:29] <Hix> Got a feeling at the low temps it could go V far
[21:29] <Upu_2E0UPU> as in grammes
[21:29] <Dan-K2VOL> wow upu, that's hot
[21:29] <Upu_2E0UPU> yes
[21:29] <Dan-K2VOL> how's the reception
[21:29] <cuddykid> definitely platoing out
[21:29] <fsphil_2I0VIM> Gas (Combustible) ??
[21:29] <cuddykid> horrendous spelling
[21:29] <Hix> BANG!
[21:29] <cuddykid> ?
[21:29] <cuddykid> oh lol Hix
[21:30] <cuddykid> I thought you meant burst :P
[21:30] <Upu_2E0UPU> fine got 3 satellites in our basement same as the Sarantel next to it
[21:30] <fsphil_2I0VIM> whatever it is, it's 14
[21:30] <Dan-K2VOL> Yeah, what is that gas reading
[21:30] <Upu_2E0UPU> I call float
[21:30] <fsphil_2I0VIM> 14 gas combustible .. that's worse than 10 right?
[21:30] <Upu_2E0UPU> all in favour
[21:30] <Dan-K2VOL> ohhh hix lol just got it
[21:30] <fsphil_2I0VIM> it's not a float until it descends a bit :)
[21:30] <Dan-K2VOL> must be, it was 1 when I last checked
[21:30] <cuddykid> I think it's dodgy - doesn't work in low pressure, that's what they thought anyway
[21:30] <cuddykid> 0.4ms - eeek!
[21:31] <Dan-K2VOL> though if it's an off the shelf sensor, I wouldn't be surprised if the number is a temperature calibration problem of the sensor
[21:31] <OZ1SKY_Brian> stop saying that, dont have time to recharge the defiblirator each time :-)
[21:31] <fsphil_2I0VIM> lol
[21:31] <Dan-K2VOL> I mean, I never see 14 combustible gas at that altitude when I measure, do you?
[21:31] <Hix> I'm going for Bremen. And I'm also going for a pint!!!
[21:31] <Hix> l8r
[21:31] <cuddykid> good shout Hix
[21:32] <Dan-K2VOL> I assume that's the school experiement
[21:32] <Dan-K2VOL> ?
[21:32] <cuddykid> yep
[21:32] <Dan-K2VOL> oh my the predictor likes that
[21:32] <Dan-K2VOL> had to zoom out
[21:32] <G8NSV> the predicted drop is getting ever so closer to Holland! if it keeps on floating it may not get its feet wet!!
[21:32] <jonsowman> 3mi from coast
[21:32] <OZ1SKY_Brian> still 434647.0 for waterfall center?
[21:32] <Upu_2E0UPU> yep
[21:33] <Upu_2E0UPU> tune up and down a little though
[21:33] <Dan-K2VOL> who's dutch mill
[21:33] Action: Upu_2E0UPU points at Dutch-Mill
[21:33] <fsphil_2I0VIM> it transmits a clear carrier now and then, you'll see that first
[21:33] <Upu_2E0UPU> the person who will be picking it up if it bursts in about 10 mins
[21:33] <OZ1SKY_Brian> ok then i might have seen it, please say when
[21:33] <danielsaul> Gas sensors: work on hot wire, more gas, hotter the wire: but no atmosphere means nothing to cool the wire so just gets hotter, falsely showing more gas - thats our theory :)
[21:33] <cuddykid> Upu_2E0UPU: not sure whether you got my question earlier - just wondering how long it took your PCBs to arrive in total from ordering to receiving?
[21:33] <Dutch-Mill> Yes
[21:34] <OZ1SKY_Brian> now?
[21:34] <Dan-K2VOL> ah Hello Dutch-Mill
[21:34] <Dan-K2VOL> good luck
[21:34] <Upu_2E0UPU> cuddykid 2-3 weeks
[21:34] <cuddykid> taa
[21:35] <Laurenceb_> gas sensors are being interesting
[21:35] <OZ1SKY_Brian> fsphil is the clear carrier the lower og upper rtty tone?
[21:35] <Dutch-Mill> Hi there bad signal overhere... don't know why .. keep an eye on the tracker and the radio
[21:35] <danielsaul> Gas sensors: work on hot wire, more gas, hotter the wire: but no atmosphere means nothing to cool the wire so just gets hotter, falsely showing more gas - thats our theory :)
[21:35] <danielsaul> Whoops
[21:35] <fsphil_2I0VIM> OZ1SKY_Brian, it's the higher tone
[21:35] <OZ1SKY_Brian> ok thanks
[21:36] <OZ1SKY_Brian> 50/300 baud is both 425Hz shift, right?
[21:36] <fsphil_2I0VIM> 31km, soooo nearly a float
[21:36] <fsphil_2I0VIM> yea
[21:36] <OZ1SKY_Brian> rgr
[21:36] <Upu_2E0UPU> its floating fsphil
[21:36] <NigeyS> i call float, 0.1m/s
[21:37] <Upu_2E0UPU> that would have triggered my float detection code and cut away
[21:37] <NigeyS> on the + side, speed is 55kph, it may hit land after all
[21:37] <RocketBoy> oh wow - its right over the met balloon launch station at hemsby
[21:37] <fsphil_2I0VIM> now it's a float!
[21:37] <cuddykid> float!

[21:38] <priyesh> Randomskk: thanks :)
[21:38] <Matt_soton> is the hat thing valid if it lands in eu, or was that just the UK?
[21:38] <Dutch-Mill> Well call LunarLander it goes to Germany ;-)
[21:39] <cuddykid> this looks to be quite a stable float - at the moment anyway
[21:39] <Randomskk> Matt_soton: "land" surely
[21:39] <jonsowman> Matt_soton: float
[21:39] <jonsowman> to add insult to injury, i don't have a hat
[21:39] <jonsowman> so i have to buy one and then eat it
[21:39] <Matt_soton> buy a chocolate one
[21:39] <jonsowman> great
[21:39] <priyesh> jonsowman: i'll buy you one
[21:39] <nigelvh> It's picked a pretty round number to do it at as well. 31km
[21:39] <NigeyS> buy a rice paper hat jon ;)
[21:39] <danielsaul> Randomskk will provide one, I,m sure
[21:39] <jonsowman> NigeyS: you're a genius
[21:40] <NigeyS> :p
[21:40] <RocketBoy> was the 1500 a recent purchase?
[21:40] <jonsowman> RocketBoy: was shipped over in the last couple of weeks from totex directly
[21:40] <priyesh> RocketBoy: it was sponsored from Totex themselves
[21:40] <priyesh> it got shipped from japan to us
[21:40] <Randomskk> maybe they made you an extra thick one

[21:41] <cuddykid> too expensive :(
[21:41] <RocketBoy> well somone ordered 8 today
[21:41] <number10_2E0DBR> maybe they want it back and its extra extra thick
[21:41] <NigeyS> :o
[21:41] <NigeyS> 8 :|

[21:42] <jonsowman> Randomskk: oh i see
[21:42] <jonsowman> RocketBoy: hmm yes
[21:42] <NigeyS> well if we suddenly see 8 balloons on the tracker...lol
[21:43] <fsphil_2I0VIM> it's over the water, arrrr
[21:43] <cuddykid> this would've got some impressive photos too
[21:43] <fsphil_2I0VIM> it's dark lol
[21:43] <danielsaul> If it wasnt dark, yeh
[21:43] <jonsowman> the sunset in cambridge was amazing
[21:44] <jonsowman> i bet it got some really good pics of it
[21:44] <fsphil_2I0VIM> that's true
[21:44] <fsphil_2I0VIM> some of my best pics where at sunset
[21:44] <NigeyS> might get some sunrise pics instead

[21:45] <RocketBoy> damn - its gonna be a pain if both totex and hwoyee don't reliably burst
[21:45] <jonsowman> that's what i was thinking
[21:45] <futurity> has the shift changed?
[21:45] <NigeyS> gonna make a cutdown pretty essential i think :|
[21:45] <jonsowman> NigeyS: agreed
[21:45] <RocketBoy> reah
[21:45] <RocketBoy> yeah
[21:46] <Upu_2E0UPU> well in fairness
[21:46] <upix> shouldn't they burst if you added more gas?
[21:46] <fsphil_2I0VIM> got a sudden boost in signal strength
[21:46] <Upu_2E0UPU> launch after sunset
[21:46] <Upu_2E0UPU> with a slow ascent rate
[21:46] <Upu_2E0UPU> I though you were aiming for a float
[21:46] <jonsowman> Upu_2E0UPU: true
[21:46] <jonsowman> ascent rate shouldn't have been that low
[21:46] <futurity> looks like the signal is to faint for me now :(
[21:46] <danielsaul> And we werent planning on launching after sunset
[21:47] <jonsowman> yeah that was due to some issues, caused by someone's transmitter. ahem.
[21:47] Action: jonsowman looks at Matt_soton
[21:48] <NigeyS> lol
[21:48] <danielsaul> We're going to sell Matt_soton a bill for everything in the payloadf
[21:48] <fsphil_2I0VIM> fading again
[21:48] <Matt_soton> well my transmitter didnt damage the GPS antenna lead :P
[21:49] <fsphil_2I0VIM> right, gonna get some supper. don't let it burst!
[21:49] <danielsaul> We damaged that taking it out the box - still yor fault :P
[21:49] <danielsaul> lol
[21:49] <jonsowman> fsphil_2I0VIM: we'll.. try?
[21:49] <jonsowman> danielsaul: we sat around with that thing inflated for 2 odd hours
[21:50] <jonsowman> and it still floated
[21:50] <priyesh> jonsowman: hat
[21:50] <jonsowman> leave me alone
[21:50] <Upu_2E0UPU> lol
[21:50] <priyesh> hehe
[21:50] <danielsaul> We like floaters here at apex
[21:50] <danielsaul> Accidental floaters
[21:51] <Matt_soton> the gps lead was taped to the side, so it wouldnt have been daamged once it was put in place danielsaul
[21:51] <jonsowman> it does seem to happen with alarming frequency
[21:51] <Matt_soton> and im still not convinced coiling the antenna lead was a good idea, but probably not the issue
[21:51] <Matt_soton> though
[21:51] <OZ1SKY_Brian> is the rtty pretty unstable ?
[21:52] <Upu_2E0UPU> no quite stable
[21:52] <Upu_2E0UPU> but not the strongest
[21:52] <priyesh> Matt_soton: well it's been coiled for weeks while i was testing it and it's fine
[21:52] <Upu_2E0UPU> the 50 baud is fine
[21:52] <Matt_soton> yea apex II was coiled, although not as lightly
[21:53] <priyesh> Matt_soton: i'm not convinced the gps antenna's coiling is to blame
[21:53] <Matt_soton> anwyay the late launch may make it float because it hasnt been exposed to the sun :P
[21:53] <upix> so whats going to happen with baloon? will burst somewhere above central europe and native team will pick up?
[21:53] <danielsaul> Forgot GPS was still running and showing chase car on spacenear...
[21:53] <Matt_soton> yea should probably ignore the coiling
[21:53] <priyesh> Matt_soton: agreed
[21:53] <SpeedEvil> So, 4 hours till .nl.

[21:54] <jonsowman> junderwood_M0JCU: Matt_soton spectrum analysed the HF txer i think
[21:54] <Matt_soton> the output was tested, but i didnt check to see what was being emitted from the rest of the board
[21:54] <Matt_soton> but then you never check the emissions from your AVR's crystal
[21:55] <junderwood_M0JCU> 'C' is the important bit - do all the transmitters and receivers get on nicely together

[21:56] <OZ1SKY_Brian> yes
[21:56] <PD3EM_shack> What's your setup OZ1SKY_Brian ?
[21:56] <OZ1SKY_Brian> IC910 preamp and comet gp9
[21:56] <_Hix> popped?
[21:57] <jonsowman> _Hix: no...
[21:57] <_Hix> nah
[21:57] <_Hix> just sink
[21:57] <Matt_soton> the output of the tranmsitter was 5th order butterworth filtered, the attenuation at 1.5GHz would have been massive
[21:57] <Upu_2E0UPU> its bobbing about
[21:57] <PD3EM_shack> OZ1SKY_Brian: Nice! Amazing with a GP!
[21:57] <OZ1SKY_Brian> when it does 300baud it looks like 3 lines on the waterfall here?
[21:57] <Upu_2E0UPU> burst will be rate -1 or lower really
[21:57] <Matt_soton> OZ1SKY_Brian: the middle one is the 3rd harmonic of the inputted square wave

[21:57] <Matt_soton> (probably)
[21:58] <Upu_2E0UPU> OZ1SKY_Brian 300 baud looks like a mess sometimes
[21:58] <_Hix> Upu_2E0UPU, briefly glitched a -3
[21:58] <Upu_2E0UPU> 50 baud just then
[21:58] <Upu_2E0UPU> now going back to 300
[21:58] <PD3EM_shack> still not geting a 100% copy with my FT-847 and Diamond X-50
[21:58] <Upu_2E0UPU> now
[21:58] <chris_99> so it's definitely 50/300 baud 8N2 right?
[21:58] <_Hix> landing prediction keeps going weird
[21:58] <Upu_2E0UPU> 300
[21:59] <OZ1SKY_Brian> shift on 300 is 425 or?
[21:59] <OZ1SKY_Brian> 50baud looks like 400Hz
[21:59] <junderwood_M0JCU> Matt_soton, the GPS could pick up IF or products from anywhere. You really need to test all the kit together at the same time.
[21:59] <Upu_2E0UPU> I have it on 325
[21:59] <chris_99> what freq is it on now?
[22:00] <Upu_2E0UPU> 434.647.48
[22:00] <chris_99> cheers
[22:00] <Matt_soton> junderwood_M0JCU: that board was i was minute thing, i probably should have done. the gps IF is only 12MHz or so thouhg
[22:00] <Matt_soton> my previous 6.78MHz one worked fine next to the GPS on the ground though
[22:00] <Upu_2E0UPU> 50 baud now OZ1SKY_Brian
[22:01] <junderwood_M0JCU> GPS is really sensitive. Look at all the trouble Lightsquared are having in the US
[22:01] <PD3EM_shack> It's floating great!!
[22:01] <Matt_soton> i thought that was because the freqencies used were near 1.5GHz so the front end couldnt remove them, this will be for a different reason, but GPS is still very sensitive
[22:02] <_Hix> Pretty slow up there. Nothing like Tims sunday German dash
[22:02] <junderwood_M0JCU> true in that case.
[22:04] <PD3EM_shack> Nice to see it's staying steady on frequency while floating!
[22:04] <OZ1SKY_Brian> got a carrier just a few hz above the high tone, not making it easyer
[22:04] <Upu_2E0UPU> yes the frequency is very stable
[22:05] <Matt_soton> that isnt a NTX2 mind you

[22:08] <jonsowman> Dutch-Mill: are you decoding?
[22:08] <_Hix> Then I'm into a whole world of coding pain
[22:09] <PD3EM_shack> isn't it more stable due to the floating? (stable temp)
[22:09] <MLow> over the sea now i see
[22:09] <MLow> uh
[22:10] <Dutch-Mill> Nope I want to grab a 300 just fiddeling with my antenna's at the moment
[22:10] <Matt_soton> when it was ascending i dont think it drifted as much as usual, dont know what others thought
[22:10] <cuddykid> pretty chilly inside -35
[22:10] <MLow> is it now predicted to float over the sea
[22:10] <jonsowman> MLow: we don't know
[22:10] <cuddykid> due to the low ascent rate
[22:10] <MLow> germany ?!
[22:10] <_Hix> warmed up by 10degC
[22:10] <OZ1SKY_Brian> allmost a good decode on 50b
[22:10] <cuddykid> hopefully it will float

[22:15] <MLow> 0.1m/s is crazy

[22:15] <MLow> somtimes it's in germany, sometimes the water
[22:16] <fsphil_2I0VIM> we should add an "if floats for another hour" mode
[22:16] <_Hix> What is predicted sunrise @ 31000m?
[22:17] <jonsowman> _Hix: depends where it is
[22:17] <jonsowman> at a _very_ rough order of magnitude estimation, an hour before on the ground
[22:17] <_Hix> yeah, true but at 50.5/h not going to be too far really
[22:17] <MLow> did it go down?!
[22:17] <fsphil_2I0VIM> yea
[22:17] <jonsowman> MLow: by a couple of metres perhaps
[22:18] <MLow> wtf indeed
[22:18] <fsphil_2I0VIM> it's oscillating

[23:00] <daveake> Yep
[23:00] <Dutch-Mill> yee 50 works fine why 300

[23:00] <Randomskk> 300 can be a lot better when driving for instance
[23:00] <fsphil_2I0VIM> no gap at all
[23:01] <Randomskk> much less prone to failure due to fading
[23:01] <G0DJA> Not criticising, I couldn't make up a payload, but swapping from one baud rate to another was a bit frought with hit and miss possibilities

[23:02] <PD3EM_shack> Thanks APEX for the flight!!!
[23:02] <Matt_soton> it would also help if it doesnt transmit the same data twice, it might as well get new data
