[00:31] <MLow-werk> i suppose radiometrix will take a few days to get back to me
[00:31] <MLow-werk> should probably refrain from refreshing email
[00:37] <fsphil-laptop> they'll all be asleep
[00:47] <fsphil-laptop> does this work for anyone? http://spooky.sanslogic.co.uk/radio.php
[00:47] <fsphil-laptop> in theory it's my radio, remote controlled
[00:47] <fsphil-laptop> may only work in firefox
[00:48] <Lunar_Lander> I'm there
[00:48] <Lunar_Lander> :P
[00:49] <fsphil-laptop> can you hear it?
[00:49] <Lunar_Lander> yeah and it was damn loud!
[00:49] <Lunar_Lander> xD
[00:50] <Lunar_Lander> damn I missed the callsign
[00:50] <fsphil-laptop> I didn't catch it either
[00:50] <Lunar_Lander> --1O-Q
[00:50] <Lunar_Lander> and something with South Korea
[00:50] <fsphil-laptop> I got Korea, that's about it
[00:50] <Lunar_Lander> yes
[00:51] <Lunar_Lander> DS1OSQ
[00:51] <fsphil-laptop> you've a better ear than me
[00:51] <Lunar_Lander> DS and DT is indeed SKR
[00:51] <Lunar_Lander> thanks :)
[00:51] <Lunar_Lander> UAZLEN
[00:51] <Lunar_Lander> actually that one guy doesn't really sound like a Korean
[00:51] <Lunar_Lander> more like a Mexican or so
[00:52] <Lunar_Lander> but fsphil-laptop the allocation of the D prefix is a question in the german radio exam
[00:53] <Lunar_Lander> correct answer is that DA to DR belong to Germany, DS and DT south korea and DU to DZ is Philippines
[00:53] <fsphil-laptop> strange they never settled with country codes
[00:54] <Lunar_Lander> yea
[00:54] <Lunar_Lander> QRZ has neither callsign
[00:54] <Lunar_Lander> but the second guy UAZLEN should be a Russian
[00:54] <fsphil-laptop> actually the amateur callsigns probably pre-dated country codes
[00:54] <Lunar_Lander> yea
[00:54] <Lunar_Lander> SV is Greece
[00:54] <Lunar_Lander> nothing like GR or Hellas or so
[00:56] <Lunar_Lander> (01:50:51) fsphil-laptop: I got Korea, that's about it
[00:56] <Lunar_Lander> there is only one Korea that is possible in this situation :P
[00:57] <fsphil-laptop> true, it's not a popular hobby in the north :)
[00:58] <Lunar_Lander> XD
[00:58] <Lunar_Lander> QH0ARM or so
[01:02] <fsphil-laptop> not sure what that last noise was
[01:02] <Lunar_Lander> yeah
[01:02] <MLow-werk> what are yall talking about?!
[01:02] <Lunar_Lander> you know what the noise reminds me of?
[01:03] <Lunar_Lander> fsphil-laptop:
[01:03] <fsphil-laptop> rtty ? :)
[01:03] <Lunar_Lander> Stephen Tyler singing AND I DONT WANNA MISS A THING
[01:03] <fsphil-laptop> MLow-werk, I've put my radio online: http://spooky.sanslogic.co.uk/radio.php
[01:03] <Lunar_Lander> KC9MWX or so
[01:03] <fsphil-laptop> listening to the local echolink node
[01:04] <Lunar_Lander> fsphil-laptop: what does that mean (found on QRZ) ""QSL only when requested, U.S.,Green stamp, $$, sufficient to meet postage costs. PLEASE, NO IRCs, thanks "
[01:06] <MLow-werk> QSL cards
[01:06] <Lunar_Lander> ah
[01:06] <MLow-werk> im at work but we have a local echolink here
[01:06] <Lunar_Lander> and the NO IRCs?
[01:08] <MLow-werk> no idea
[01:08] <Lunar_Lander> fsphil-laptop: morse and telephone
[01:08] <Lunar_Lander> XD
[01:09] <fsphil-laptop> someone's having fun there
[01:09] <Lunar_Lander> LQA or so
[01:09] <fsphil-laptop> NWX
[01:09] <Lunar_Lander> KC9NWX
[01:09] <Lunar_Lander> yea
[01:10] <fsphil-laptop> you can retune it but there's not much else going on
[01:10] <Lunar_Lander> yea
[01:11] <Lunar_Lander> other than BBC Ulster?
[01:11] <Lunar_Lander> :P
[01:11] <fsphil-laptop> ah they just play rubbish
[01:11] <Lunar_Lander> XD
[01:11] <Lunar_Lander> Ruth Jones is hot
[01:11] <Lunar_Lander> do you know her?
[01:11] <fsphil-laptop> no :p
[01:11] <Lunar_Lander> ah well, yea
[01:11] <Lunar_Lander> you don't like Gavin & Stacey
[01:13] <Lunar_Lander> so those people, the Russian, KC9NWX and the South Korean don't talk to you directly?
[01:13] <Lunar_Lander> UA0LAN
[01:13] <Lunar_Lander> or so
[01:13] <Lunar_Lander> UA0LAN yea
[01:13] <Lunar_Lander> UA0LEN
[01:14] <fsphil-laptop> I could talk to them
[01:14] <Lunar_Lander> ah
[01:14] <Lunar_Lander> but it's via another station right?
[01:14] <Lunar_Lander> that echolink
[01:14] <fsphil-laptop> yea
[01:14] <fsphil-laptop> each echolink node is linked to the internet
[01:14] <Lunar_Lander> there is one at the roof of uni
[01:14] <Lunar_Lander> ah
[01:14] <fsphil-laptop> this one is about 15 miles from me
[01:15] <Lunar_Lander> and mattltm could talk to my Stabo via the Uni link
[01:15] <Lunar_Lander> :P

[01:29] <Lunar_Lander> 4S7SWP maybe
[01:30] <fsphil-laptop> I better get some sleep
[01:31] <Lunar_Lander> yes

[08:24] <cuddykid> the skies look snowy
[08:24] <cuddykid> and indeed there is snow forecast
[08:28] <eroomde> therefore
[08:28] <cuddykid> it probably won't snow :D
[08:28] <cuddykid> lol
[08:28] <cuddykid> yay - on page 3 today ;)
[08:32] <eroomde> ahem
[08:37] <cuddykid> fortunately it's not the sun et al
[08:38] <fsphil> we've had one day of snow here. *annoyed*
[08:39] <fsphil> I don't remember such a mild winter before
[08:43] <cuddykid> snow still hasn't melted here, most fields are white over :(
[08:43] <cuddykid> it's just annoying how they can't cope for a day or so after the small amount of snow falls
[08:44] <fsphil> yea that is annoying
[08:44] <fsphil> it's almost like they don't expect it, and have never seen it before
[08:44] <cuddykid> yep
[08:45] <cuddykid> it's also annoying trying to bike to lectures in the snow!
[08:45] <cuddykid> talking of lectures, I've got my first and last one for today now :P bbl
[08:53] <costyn> cuddykid: IRCing during class eh? :)

[09:05] <gonzo_> I used to use good old packet AX25 during lectures, which was cutting edge at the time.
[09:05] <Darkside> during lectures?
[09:06] <gonzo_> (I'm risking another old farts nostalgia session here!)
[09:06] <Darkside> were you a lecturer or a student...
[09:06] <gonzo_> yep, email was pretty much unheard of then
[09:06] <gonzo_> hehe, I'm old but not THAT old!
[09:07] <gonzo_> a TNC and radio in an ali camera case and what passed for a laptop of iot's day
[09:08] <Darkside> lol
[09:08] <Darkside> niiiice
[09:10] <gonzo_> it seemed so 'james bond' to most people that I was often asked 'what ARE you?'
[09:10] <Darkside> loool
[09:10] <Darkside> i get enough strange looks with my Kenwood TH-D72 on me bag-strap
[09:20] <fsphil> what radio gonzo_?
[09:21] <fsphil> I can't imagine it was a very subtle setup :)
[09:22] <gonzo_> nope it was a bit bulky and wires everywhere.
[09:22] <gonzo_> From mem it was a trio/kenwood TH21e
[09:23] <gonzo_> tiny for it's day. But the tiny2 TNC and gel cell batt were a bit bigger
[09:24] <gonzo_> the laptop did have a whole 7 lines of 40chr though. Big league
[09:24] <fsphil> "G0NZO> lecture boring, lolz"
[09:25] <gonzo_> my stuff did seem to get more interest than the lecture so had to stop usiong it, was getting 'looks' from the lecturer
[09:26] <fsphil> I was caught with a pocket TV in RE class in high school
[09:26] <gonzo_> the halls of rez did have a dumb term into the vax on a leased line. How things have moved on!
[09:27] <gonzo_> fair enough, some people thuink tv is a releigion in it's own right
[09:28] <fsphil> aah wish I'd thought of that at the time
[09:28] <fsphil> wonder if that teacher is still there...
[09:29] <fsphil> that tv will be useless by the end of the year, no more analogue
[09:32] <fsphil> I've got a very very expensive device, and the serial port and power supply socket are exactly the same
[09:32] <fsphil> that's terrible

[10:26] <cuddykid> LOL daveake_
[10:27] <cuddykid> Hi Bill, the ntx2 has stopped transmitting rtty!
[10:28] <number10> cuddykid: when tracking habe and cloud at the weekend, I noticed that clouds decodes were far more reliable when the signal strength was a lot lower compared to yours - I was wondering if you still had some timing issues on rtty
[10:29] <daveake_> "HABE 3 - Sponsosred by Red Bull"
[10:32] <eroomde> Upu: does your eagle part library for the neo6 and max6 parts exist somewhere?
[10:32] <UpuWork> hey eroomde yep
[10:32] <eroomde> more generally, we should maybe have a ukhas eagle library in the vein of sparkfun's
[10:33] <cuddykid> number10: yeah, I noticed that the signal was far far poorer than my last flight - I'm putting it down to dodgy connections to antenna - I tried to botch up by connecting the board to old antennas - code hasn't changed since last flight, so I don't think it would be the code
[10:33] <cuddykid> eroomde: that would be good
[10:33] <UpuWork> https://github.com/Upuaut/Eagle-Libraries/blob/master/ava.lbr
[10:33] <UpuWork> Yeah considered that eroomde
[10:33] <eroomde> really just for the radiometrices and ubloxs
[10:33] <eroomde> ah monster
[10:33] <eroomde> thanks UpuWork
[10:33] <UpuWork> if you use the MAX6 can you buy them off me pretty pls when I get them in stock
[10:33] <eroomde> yes indeed
[10:33] <UpuWork> thx
[10:34] <eroomde> you'll see i asked you that the other day :)
[10:34] <UpuWork> oh ok :)
[10:34] <eroomde> when you were getting some as i'd rather get them off a fellow habber
[10:34] <UpuWork> They will be considerably cheaper than from Alphamicro direct
[10:34] <UpuWork> Almost there with the online shop
[10:35] <UpuWork> just need to test the breakout boards when "monkey" returns them from Seeed
[10:35] <eroomde> cool
[10:35] <UpuWork> The NEO-6 has been tested and works, the MAX-6 isn't tested but looks correct when I print it out
[10:35] CovBalloon (CovBalloon@cpc7-cove12-2-0-cust297.3-1.cable.virginmedia.com) joined #highaltitude.
[10:35] <eroomde> what will they cost, approximately?
[10:36] <UpuWork> £17.23 inc VAT for the MAX6 with UKHAS discount
[10:36] <eroomde> grand
[10:37] <eroomde> are you getting the 6Qs?
[10:37] <cuddykid> UpuWork: do you think we can do something similar with RFM22Bs?
[10:37] <UpuWork> MAX6Q 3V module yes
[10:37] <UpuWork> yes cuddykid
[10:38] <UpuWork> I've also asked Radiometrix for a quote on NTX modules in volume
[10:38] <cuddykid> brill
[10:38] <cuddykid> our little HAB shop :D
[10:39] <UpuWork> putting some of the other bits on there too like SMA connectors
[10:39] <eroomde> so, the atmegaxxxP's will do 1.8V
[10:40] <eroomde> the max units (q varient) will do 1.8V
[10:40] <cuddykid> eroomde: is there any advantage of 1.8V?
[10:40] <eroomde> SD cards have a 1.8V mode, but i think you need 3.3V initially to tell them to go into 1.8V mode
[10:40] <eroomde> cuddykid: power consumption
[10:40] <cuddykid> ahh right
[10:40] <eroomde> i don't know about 1.8V radios though
[10:40] <cuddykid> 1.8v GPS?
[10:40] <eroomde> ntx2 drops out of the running
[10:40] <eroomde> yep
[10:40] <cuddykid> :D
[10:41] <eroomde> the 1.8V max6 has a power save mode (1hz updates) where it consumes 22mW
[10:41] <eroomde> compared to 36mW for the 3.3v mode
[10:41] <cuddykid> that sounds good - could be powered easily by one of my teeny solar panels :)
[10:41] <cuddykid> average power for the flight was 58mW
[10:41] <cuddykid> with max power coming out around 450mW
[10:41] <eroomde> an energizer lithium ultimate is 1.5V, 3AH = 4500mWh juice
[10:42] <eroomde> so if you could get your payload to the 60mW mark in its entirity (gps + atmega + radio) then you could be looking at about 3 days of running from a single AA
[10:43] <eroomde> which would be a win for pico, long duration payloads
[10:43] <eroomde> but it's definitely more faff than sticking with 3.3V
[10:43] <eroomde> which i will be doing
[10:43] <eroomde> and so will be buying a few modules off upu
[10:44] <UpuWork> Ok I mailed hoperf about the RFM22B's
[10:44] <UpuWork> see what they come back with
[10:44] <daveake_> Make sure they send rfm22bs and not a bluetooth module :p
[10:44] <cuddykid> haha
[10:44] <UpuWork> that probably wouldn't work
[10:45] <eroomde> ah upu is that library eagle6?
[10:45] <daveake_> Nope. Sent mine back yesterday
[10:45] <UpuWork> yes eroomde
[10:45] <eroomde> ah tits
[10:45] <UpuWork> they've fixed Eagle 6 now
[10:45] <UpuWork> so you're ok to upgrade
[10:45] <eroomde> i have a paid for license for 5 though
[10:45] <eroomde> well, i'll give it a whirl
[10:46] <UpuWork> I might have the library for 5 somewhere still
[10:46] <UpuWork> but it won't have the MAX in it
[10:46] <eroomde> it's ok
[10:46] <eroomde> this module i'm building is 50mm x 30mm, 2 layer
[10:46] <eroomde> so it's no biggie
[10:47] <eroomde> work will upgrade my license when i need it
[10:47] <UpuWork> I think this pico board I'm doing for jcoxon is going to be about 34mm x 30mm
[10:47] <UpuWork> maybe larger if this chip antenna works
[10:47] <eroomde> i don't know how much of a squueze my one will be
[10:48] <eroomde> hopefully not too much
[10:48] <eroomde> i want the basics in there though
[10:48] <UpuWork> well loosing the NTX2 and using RFM22B saves a huge amount of space
[10:48] <eroomde> SD card, a pyro channel with continuity testing, temp/pres, and an ntx2
[10:48] <eroomde> yeah, that would be the sensible thing to do - loose the ntx2
[10:48] <eroomde> but, the vco is just too damn nice
[10:49] <gonzo_> btw Upu, I went back over my figures for GPS signal strengths and looks like I was out by 25dB
[10:49] <eroomde> as i want to start flying more intelligent modes like dominoex
[10:49] <UpuWork> only a small amount ?
[10:49] <eroomde> and you just need that fine grained freq control that the vco gives you
[10:49] <gonzo_> prob explains why your small helix works when my calcs said it shouldn't
[10:49] <UpuWork> Helix works amazingly
[10:49] <eroomde> looking at gps signal strength is pretty depressing isn't it
[10:50] <eroomde> it's like 15dB beneath the noise floor at best
[10:50] <UpuWork> only downside is they are relatively heavy for pico applications
[10:50] <daveake_> " pyro channel with *continuity testing*" what a good idea
[10:50] <UpuWork> Ava has one of those
[10:50] <eroomde> oh all our payloads definitely have that now and have had for a while
[10:50] <eroomde> it's *so* useful
[10:50] <daveake_> Something I wish I'd thought of :)
[10:50] <eroomde> just to be able to sanity check before launch
[10:50] <daveake_> Yep
[10:50] <UpuWork> Helpful as well so the controller knows if the pyro has fired sucessfully
[10:51] <daveake_> yep
[10:51] <gonzo_> well, the figues I had were wrong. Someone posted them as -130dBm on the surface and infered that that was per3^2
[10:51] <eroomde> especially with something like our parachute test vehicle where the pyros really really need to work
[10:51] <UpuWork> mind you the sudden rapid decent should also be a give away
[10:51] <gonzo_> but is actually isotropic
[10:51] <daveake_> :)
[10:51] <eroomde> UpuWork: yes indeed that too
[10:51] <daveake_> NMust put my accelerometer back on too
[10:51] <UpuWork> I'm trying to work out how to solder these BMP085's on
[10:51] <eroomde> my other pyro tip, which is not a particularly non-obvious one, is to stick a ballast resistor in series with the pyro
[10:51] <eroomde> like, 1 or 2 ohms
[10:51] <UpuWork> without spending £2000 on a reflow oven
[10:52] <eroomde> because often form a plasma for a few ms when they fire (maybe 10-20ms) which can be a nasty short and reset your flight comp quite easily
[10:52] <daveake_> oo
[10:52] <UpuWork> good tip
[10:52] <zyp> I spent £200 on a reflow oven
[10:52] <eroomde> UpuWork: we use a £19.99 toast oven from argos
[10:52] <eroomde> works like a charm
[10:52] <UpuWork> haha
[10:53] <UpuWork> well I am considering an electric skillet
[10:53] <eroomde> we did all the badger flight computers (2 and cub) with it
[10:53] <UpuWork> did you use a mask and solder paste ?
[10:53] <eroomde> yes
[10:53] <UpuWork> where did you get the mask made ?
[10:53] <gonzo_> I've done similar on a hot plate, which was a lumop of steel on a camping stove
[10:53] <eroomde> a stencil is well worth the money if you're doing more than 1 or 2 of a board
[10:53] <eroomde> UpuWork: pcb train
[10:54] <gonzo_> use leaded solder, makes the temps lower
[10:54] <eroomde> they will do you a stainless steel one (worth it) for like £25 inc p&p 2 day servic4
[10:54] <UpuWork> just send them the Gerbers ?
[10:54] <eroomde> yep

[10:55] <UpuWork> cheers
[10:55] <UpuWork> ok quick meeting back soon
[10:56] <eroomde> the nice thing about the solder oven is you can heat evenly
[10:56] <eroomde> so all the solder paste tends to melt at once
[10:57] <eroomde> whereas with an iron or hot air, once side of a passive will likely melt before the other and the surface tension from the first-melted pad will drag the passive into some annoying new position
[10:57] <eroomde> or make it tombstone
[10:57] <eroomde> and you wish you had 4 hands
[10:57] <eroomde> to hold everything down, apply iron, apply solder
[11:00] <eroomde> right, eagle 6 won't install on ubuntu
[11:00] <eroomde> that sucks
[11:00] <fsphil> same with fedora
[11:00] <fsphil> some libpng problem
[11:00] <eroomde> yes exactly
[11:00] <gonzo_> I used to find that the surface tension used to help pull chips into place. That was qfp though
[11:00] <eroomde> gonzo_: that's true in the oven i find
[11:01] <eroomde> you can see them all wiggle into place when the solder melts
[11:01] <eroomde> but if you can only melt one half of the pads at a time, it doesn't work so well - the forces on the part are assymetric
[11:01] <gonzo_> I was using an IR rework station. That heated the board from underside and a shuttered IR source on top
[11:01] <eroomde> ah nice
[11:02] <eroomde> fsphil: the ubuntu repos only have up to libpng12-dev
[11:02] <gonzo_> was a work unit though, not mine infortunatly
[11:03] <fsphil> they'd be better compiling it with a static libpng
[11:07] <eroomde> agreed
[11:10] <eroomde> oh whyyyy

[11:32] <number10> trying stuff on
[11:43] <fsphil> eroomde, stencil just lets the solder paste onto the pads doesn't it? then all the parts are placed at once, and the entire board oven'd?
[11:44] <zyp> yep
[11:45] <zyp> http://bin.jvnv.net/f/bIChx.jpg <- my first attempt at stencil, paste and reflow
[11:47] <eroomde> fsphil: correct
[11:47] <eroomde> you want to get the board in the oven within a few hours of getting the paste down ideally
[11:47] <eroomde> an hour ot two, say
[11:48] <eroomde> cos solder paste goes off quite quicky
[11:48] <eroomde> which is why you should keep it in the fridge
[11:48] <eroomde> also it's generally not a good thing to have lying around, i find
[11:48] <eroomde> it seems to get everywhere and it's toxic and quite unpleasant
[11:49] <eroomde> i got a mouthful of it once when building badger2
[11:49] <eroomde> someone put the stencil down (paste side down) ointo my coffee mug
[11:49] <eroomde> then took it off to clean up
[11:49] <daveake_> lol
[11:49] <eroomde> and i took a swig from my mug without really looking at it first
[11:49] <daveake_> ugh
[11:49] <eroomde> and wondered why my throat started to get a burning sesation
[11:49] <eroomde> flux and lead, was why
[11:51] <zyp> wtf, that's silly
[11:51] <UpuWork> £11.04 for an NTX2 inc VAT
[11:51] <UpuWork> any good ?
[11:52] <daveake_> !!
[11:53] <eroomde> blimey
[11:53] <daveake_> So that's £9.20 + VAT, and Farnell are £25.18+VAT
[11:53] <WillDuckworth> not bad at all
[11:53] <eroomde> i'll tap that
[11:53] <UpuWork> My concern is
[11:53] <UpuWork> I'd have to buy 50 and if you all start using RFM22B's :)
[11:53] <daveake_> lol True :)
[11:54] <eroomde> i'll buy one UpuWork :)
[11:54] <eroomde> not interested in to frmblah
[11:54] <eroomde> frm*
[11:54] <daveake_> Remember though the NTX2 is easier to use and needs no libraries, so it'll still have a use for HAB
[11:54] <eroomde> it's actually a lot more capable
[11:54] <UpuWork> I'll consider it
[11:55] <eroomde> it'll wipe the floor with rfm22bs as soon as you go for a more efficient modulation scheme
[11:55] <eroomde> eg dominoex
[11:55] <daveake_> for a memoment I thought you typed ... oh, never mind :)
[11:55] <daveake_> *moment
[11:56] <eroomde> a memoment

[12:18] <number10> I could do with one of those
[12:26] <cuddykid> just put a tesco employee who was trying to fob me off back in her place :D
[12:28] <cuddykid> spotted a misprice error on the orange juice, then she tried to tell me that the label was about something else - clearly not when word for word name was the same! She was having none of it, and told me to get the "smooth" version instead (which she thought the name was pointing at), I told her to scan it and yes, I was right, there was a pricing error on that too! Oh dear, sometimes I wonder where they get these people from
[12:29] <daveake_> from the "Value" line at the job centre
[12:30] <number10> they dont get paid very much. I overheard a couple of conversations in tesco - If they need a pen, the staff have to suplly their own,

[14:00] <fsphil> the last site wanted me to register as a business, these guys don't mind individuals?

[14:01] <daveake_> No, not at all
[14:01] <fsphil> are they a boc retailer?
[14:01] <fsphil> if so then I can collect from the place up the road from here

[15:45] <Lunar_Lander> UpuWork: how far do you think do the frequencies of two transmitters have to be?
[15:45] <Lunar_Lander> could one use two NTX2 with .650 and .075 in the same payload?
[15:46] <daveake_> With separate aerials, no problem. With one aerial someone else will need to advise.
[15:47] <gonzo_> you should be able to use any frequencies as long as they don't thermally drift into each other
[15:47] <Lunar_Lander> yea
[15:47] <Lunar_Lander> I thought of two antennas
[15:47] <Lunar_Lander> but was only a thought
[15:47] <Lunar_Lander> one transmitter should be enough
[15:47] <Lunar_Lander> :)
[15:47] <daveake_> With one I think you'd lose a bit of power
[15:47] <Lunar_Lander> yea
[15:48] <daveake_> But yes the frequencies themselves no problem at all. They'd have to get really close to interfere
[15:48] <Lunar_Lander> true
[15:48] <gonzo_> if you used the IQ modulator idea, you could theoretically put multiple carriers into a downlink
[15:49] number10 (d42c14ce@gateway/web/freenode/ip.212.44.20.206) left irc: Quit: Page closed
[15:49] <Lunar_Lander> ah
[15:50] <gonzo_> you could reasonably easilly combine a couple of ntx2 modules, with a hybrid ring combiner. It's how the amsat satelites do it
[15:51] <gonzo_> but separate antennas is safer. more redundancy
[15:53] <Lunar_Lander> yea
[15:56] <fsphil> Lunar_Lander, I've seen two ntx2's on the one payload - .650 and .075, two antennas (one top, one bottom) - worked fine
[15:56] <Lunar_Lander> cool!
[15:57] <gonzo_> you could put one on .076 and 0.75, if you could be sure they would not drift at different rates and bump into eachother
[15:57] <daveake_> cloud3 has 2 transmitters at .65 and .2, different payloads of course.
[15:58] <Lunar_Lander> yea
[15:58] <gonzo_> lots of redundancy there dave
[15:58] <daveake_> needed it :)
[15:58] <gonzo_> if it can go wrong it will
[15:58] <gonzo_> and an incoming tide!
[15:58] <daveake_> Indeed, and the smaller payload was best in the air but died on splashdown, so I did need both :)
[15:59] <Lunar_Lander> yeah and we need to make a HAB motion picture
[15:59] <Lunar_Lander> in HD and 3D
[15:59] <gonzo_> it was suprisingly strong
[15:59] <daveake_> Yeah, I knew before launch that the wind would be in my favour if it did splashdown, but I didn't think of checking the tide tables
[15:59] <gonzo_> better antenna pattern on the RFM22?
[16:00] <gonzo_> it was quite raspy keyimg though, any idea what that was?
[16:00] <daveake_> Both were the same idea - 4-wire ground plane + 1/4 wave
[16:00] <gonzo_> synth relock on freq change?
[16:00] <daveake_> raspy? "they're all like that, Sir" :)
[16:00] <gonzo_> hehe
[16:00] <gonzo_> what was the antenna orientation?
[16:00] <daveake_> jcoxon reported the same, and it was his code I was using
[16:01] <daveake_> antenna straight down; gp at 90 degrees
[16:01] <fsphil> Lunar_Lander, 3D?
[16:01] <gonzo_> suspect it's intrinsic to the way you key the unit
[16:01] <daveake_> buzz was a few metres lower but it won't be that @D
[16:01] <daveake_> yes
[16:02] <gonzo_> Didn;t seem to cause any problems thoygh. The ntx2 was very clean
[16:02] <daveake_> the rfm22 was certainly stronger in the chase car. Suspect the ntx2 aerial was bent
[16:03] <daveake_> I'll flow both again ina few weeks
[16:03] <gonzo_> well power measurement is notoriously inprecise, so a few db up on one and a few down on the other could explainpart of it
[16:03] <Lunar_Lander> fsphil: yeah 3D for cinemas
[16:03] <Lunar_Lander> :)
[16:04] <gonzo_> the rfm22 was 10db stronger at my rx (reasonably accurate measurement using the SDR)
[16:05] <daveake_> We lost the rfm22 signal at about 600 metres up. Even when we got close to the beach there was nothing (the salt water killed it). So I was more than a bit relieved to see the ntx2 signal when I re-tuned
[16:05] <Lunar_Lander> yea
[16:05] <Lunar_Lander> Radiometrix Rocks!
[16:05] <daveake_> In that instance it went from "oh shit I lost another one to the sea", to "I'm gonna get this one back, one way or another" :)
[16:06] <Lunar_Lander> yeah
[16:06] <daveake_> Didn't realise it was going to make its own way home
[16:06] <Lunar_Lander> fsphil: another idea would be, now that James May attended a launch, that we could invite Rowan Atkinson

[16:13] <Lunar_Lander> is there some sauce with the fish & chips?
[16:13] <daveake_> salt (well not for me) & vinegar
[16:13] <Lunar_Lander> ah
[16:14] <fsphil> chips need either red or brown sauce
[16:14] <Lunar_Lander> or majonaise?
[16:14] <daveake_> Are you from Belgium?
[16:14] <Lunar_Lander> no
[16:14] <daveake_> (and yes we did have chips and mayo in Bruges)
[16:14] <Lunar_Lander> yay

[20:41] <nigelvh> Ah. I don't wear those. So all my clothes are wearable in public.
[20:41] <Lunar_Lander> ah
[20:41] <nigelvh> Makes life a little easier
[20:42] <nigelvh> Also less laundry.

[20:49] <cuddykid> lol, looked at my blog stats and found out that I had 6 views from some random french website - went there and it was a french ham radio website
[20:50] <cuddykid> they were complaining that they couldn't do similar projects in france
[20:50] <Lunar_Lander> XD
[20:50] <daveake_> That's because of the danger that anyone seeing a HAB fall out of the sky will probably surrender to it
[20:51] <Lunar_Lander> LOL
[20:51] <daveake_> cuddykid How did the easymodem testing go?
[20:51] <daveake_> easyradio I mean
[20:51] <cuddykid> daveake_: not good, I'm ditching them
[20:51] <cuddykid> range was terrible
[20:51] <daveake_> ok. Unsurprised.
[20:51] <fsphil> daveake_, er, find
[20:51] <daveake_> Good fsphil. Just checking :)
[20:52] <cuddykid> however, I didn't manage to do the testing I wanted though, as it was so cold and a quick pack up and drive
[20:53] <fsphil> they recommend wetting the balloon during filling
[20:54] <Lunar_Lander> yeah

[20:54] grummund (~user@unaffiliated/grummund) left irc: Ping timeout: 252 seconds
[20:54] <Lunar_Lander> when they put the balloons into boiling water before inflation, they climbed higher than if they were stored in diesel
[20:54] <fsphil> each time I read something like that I start to think that really Helium is probably the better way to do it
[20:55] <fsphil> although the two recommendations there are quite easy -- anti-flame coat and wetting the balloon

[20:56] <Lunar_Lander> fsphil: well yeah, a H2 inflation with a diesel soaked balloon
[20:56] <daveake_> :D
[20:56] <Lunar_Lander> would be bad

[22:00] <cuddykid> and poor daveake having to deal with most of them!
[22:00] <Lunar_Lander> I read about fuses that have to be set
[22:00] <Lunar_Lander> rofl
[22:00] <Lunar_Lander> is that like that there a fuses in the chip?
[22:00] <Lunar_Lander> fuses like in an electrical box?
[22:00] <cuddykid> hmm - not sure
[22:00] <cuddykid> never heard of any :S
[22:00] <fsphil> I'm not sure what they physically are, but they can be unset
[22:00] <Lunar_Lander> ah
[22:01] <Lunar_Lander> what happens if set incorrectly?
[22:01] <fsphil> depends on the fuse and its function
[22:01] <fsphil> I suspect there are combinations that would stop it working

[22:09] <fsphil> on windows yea
[22:10] <Lunar_Lander> yes
[22:10] <Lunar_Lander> but you have to write a program that you want to put into the chip
[22:12] <MLow-werk> probably easier to make a hackuino
[22:12] <MLow-werk> arduino 1.0 ide uploads using a programmer now, instead of needing the ftdi chip for serial programming
[22:12] <Lunar_Lander> yes
[22:15] <MLow-werk> put a atmega on breadboard with a usb programmer
[22:16] <MLow-werk> usbtinyisp is 15$
