[08:28] <arko> Yes it is
[08:28] <arko> Very cool
[08:28] <fsphil> it's one of those sstvcams
[08:28] <jonsowman> was there a ukhas mail list about Bill's flight?
[08:28] <fsphil> little camera that puts out ssdv directly
[08:28] <fsphil> jonsowman: nope, he's just done the gpsl list
[08:28] <fsphil> I'll forward it
[08:28] <arko> Sweet, I need to talk to him about that. I want to do that for my pici
[08:28] <arko> Pico
[08:29] <jonsowman> ah that'll be why, thanks fsphil
[08:29] <jonsowman> arko: the ocean current predictor is great -- what's it for?
[08:29] <arko> For funz
[08:29] <griffonbot> Received email: Philip Heron "[UKHAS] Fwd: Huntsville AL Balloon with SSTV this Sunday morning"
[08:29] <jonsowman> :)
[08:30] <arko> We are talking about building a beacon to track ocean currents
[08:30] <fsphil> sstv* pictures directly
[08:30] <arko> Build it on the cheap
[08:30] <arko> So I decided to break out of the ee world for a change this week and write up a predictor for ocean :)

[08:33] <arko> Haha!!
[08:33] <arko> Nice
[08:33] <jonsowman> nessie (server's) replacement was (is) kraken
[08:33] <jonsowman> and now there's another ocean drifter project called kraken
[08:33] <arko> Ah! That's awesome
[08:33] <arko> Yeah kraken launches April 7
[08:34] <fsphil> does that mean I have to name mine tiamat?

[08:52] <M0TVU> Can anyone tell me the details for SP9UOB
[08:53] <chrisstubbs> 0900 UTC Gliwice, Poland SP9UOB/SR0FLY 50.807Mhz RTTY / 437.600Mhz RTTY according to spacenear
[08:53] <fsphil> 50.807 MHz RTTY 50 baud, 7n1, shift 470 Hz
[08:53] <G0DJA> There was me frantically loading FLDigi and refreshing the flight docs, refreshing Tracker to see which way to point the antenna for HORUS...
[08:53] <fsphil> hah
[08:53] <Upu> M0TVU its unlikely you're going to receive that one
[08:54] <Upu> haha
[08:54] <Upu> yes Horus is a little out of our range in the UK
[08:54] <M0TVU> I think so
[08:54] <fsphil> 50mhz can travel quite far if conditions are good
[08:54] <fsphil> I'm gonna have a listen
[08:54] <M0TVU> I have a full size 3 ele for 6m
[08:54] <M0TVU> with a VERY good take off to the east
[08:54] <Upu> swing it round and take a listen
[08:55] <Upu> be an impressive range
[08:55] <M0TVU> I can hear something with a wide shift
[08:55] <chrisstubbs> Has speed been added to spacenear.us as a server side calculation?
[08:55] <Upu> don't think so chrisstubbs I think its from the payload I might be wrong though we were talking about it
[08:56] <G0DJA> I thought it was the Polish one that had 50MHz
[08:56] <chrisstubbs> ah ok
[08:56] <Upu> it is the polish one that has 50Mhz
[08:57] <Upu> Horus is RTTY on 2meters
[08:58] <M0TVU> I have something on 50.810 with an 820 shift
[08:58] <fsphil> this is 470 hz
[08:59] <M0TVU> Where do you find the details?

[12:03] <GMT> if you've got it set-up correctly FLDIGI will tell you bearing and distance to balloon

[12:09] <chrisg7ogx> got her tks all
[12:09] <Willdude123_> I've lost it completely.
[12:09] <Babs> well, I have to say for a first go I am enjoying myself immensely. The neightbours do not know what the bejesus is going on as I walk around my roof terrace holding a bit of wire above my head.
[12:09] <eroomde> Willdude123_: and what about the balloon?
[12:09] <mfa298> where's the wind to blow this a little to the west when you want it - I think I've lost it now due to the local re-inforced concrete
[12:09] <Willdude123_> What?
[12:09] <Willdude123_> I've lost signal.
[12:10] <eroomde> i was being silly
[12:10] <Willdude123_> For AVA.
[12:10] <eroomde> ignore me
[12:10] <Willdude123_> I shouldn't have.
[12:10] <Geoff-G8DHE> <Babs> They don't even realise you have a balloon attached to the wire .....
[12:10] <GMT> Will, you're the closest to it! stay with it, the sig will come back
[12:10] <Willdude123_> It's quite close.
[12:10] <Willdude123_> What frequency should I be on?
[12:10] <GMT> 434.555
[12:10] <mfa298> Willdude123_: you mighe need to tune around a bit as it's been drifting a bit
[12:11] <chrisg7ogx> by comparison with yesterday ava is a wee bit unsteady on her feet!
[12:11] <eroomde> Babs: could you remind me if your flickr url?
[12:11] <GMT> but AVA has a superb signal, HABE was crap (sorry Cuddy!)
[12:11] <eroomde> i want to show someone
[12:11] <Geoff-G8DHE> But it was short of an aerial!
[12:12] <daveake> Yeah AVA is more wibbly than I'd expect
[12:13] <Willdude123_> Getting nothing at all.
[12:13] <chrisg7ogx> eromode you can get locked up for that
[12:13] <Willdude123_> I'll move the antenna about.
[12:13] <GMT> Wull: what receiver ... RTL dongle isnt it?
[12:13] <Willdude123_> FCD.
[12:14] <Babs> Geoff-G8DHE - arf
[12:14] <GMT> okay, what kind of aerial?
[12:14] <Willdude123_> Quarter Wave
[12:14] <Babs> eroomde http://www.flickr.com/photos/91049302@N00/
[12:14] <eroomde> chrisg7ogx: we're both consenting
[12:14] <eroomde> Babs: thanks
[12:14] <chrisg7ogx> ava great sigs' it was me trying to calibrate fcd pro plus...way off freq
[12:15] <Babs> no worries
[12:15] <chrisg7ogx> lol. will dude u prob have to tune abt a bit zare you familiar with the the rtty sounds?
[12:15] <mfa298> chrisg7ogx: my experience is the FCD+ is fine if you've done the correct settings in sdr# (reverse IQ and remove the default frequency correction)
[12:16] <Willdude123_> chrisg7ogx: Yep.
[12:16] <Willdude123_> I could receive earlier.
[12:17] <Willdude123_> I might call it a day.
[12:17] <GMT> maybe because AVA is above you so not so good signal to your aerial?
[12:17] <Willdude123_> Wait, I don't have line of sight.
[12:17] <chrisg7ogx> mfa298 where is is default rf correction on sdr# not familiar with itb but using it now
[12:18] <Willdude123_> But my sister wouldn't let me put an antenna out her window.
[12:18] <gonzo_> Willdude123 if you are anywhere near a built up area, you could look at 433.900 That shoudl be full of pops and chirps
[12:18] <gonzo_> a useful sanity check
[12:18] <GMT> OGX, 'stop', and its under Configure button
[12:18] <mfa298> chrisg7ogx: it's something like config or settings next to the radio dropdown at the top of the window
[12:19] <craag> chrisg7ogx: It's labelled the 'Frequency Correction' in ppm.
[12:20] <Willdude123_> I'll stop trying to track now
[12:20] <craag> Willdude123_: Have you got a view out to the horizon in the direction that it is?
[12:20] <daveake> Willdude123_ Can you see the signal at all?
[12:20] <Willdude123_> Nope, and nope.
[12:20] <chrisg7ogx> yes got it tks. have to leave now will set it up to playalone
[12:21] <daveake> Have you changed anything since earlier when it worked?
[12:21] <Willdude123_> Nope, but I don't have LOS anymore.
[12:21] <daveake> Well if something is in the way, wait till it clears that, which it will
[12:21] <daveake> Remember it's got a long way upwards to go
[12:22] <chrisg7ogx> willdude..u may be in ur blind spot if ava is close to u persevere matey!
[12:22] <Willdude123_> I'll have to just move my house one second.
[12:23] <Willdude123_> :)
[12:23] <craag> Complete blockage to the south?
[12:23] <Willdude123_> Yep.
[12:23] <mfa298> Willdude123_: just keep at it, hopefully it will get to a position where you can get it again.
[12:23] <daveake> I'd expect you to be able to get a signal from outside quite easily
[12:24] Action: mfa298 is surprised i'm still getting strings with the amount of re-inforced concrete in the way
[12:24] <Maxell> woot, decodeds

[12:24] <craag> Maxell: Great, and it's coming your way!
[12:24] <GMT> Maxell: impressive distance
[12:25] <mfa298> Maxell: well done and it shoud only get stronger for you!
[12:25] <Willdude123_> I'll see if I can get my antenna anywhere better.
[12:25] <GMT> I will make a phone-call to the AVA-naut in his capsule under the balloon, and get him to point the beam antenna in your direction
[12:25] <mfa298> Willdude123_: at this point it's a case of playing around (and the waterfall should make it easier)
[12:25] <chrisg7ogx> deep qsb here now
[12:26] <mfa298> with weak signals I've found very small movements can make a big difference

[13:19] <jcoxon> Hey all
[13:19] <jcoxon> updates?
[13:20] <daveake> AVA doing well; ascent rate a tad higher than we'd hoped. Half a zillion listeners.
[13:20] <costyn> cuddykid: does the IOS app update the payloads by itself? I had started it earlier today when AVA wasn't on the map yet, but it's not appearing now... or should I be more patient
[13:20] <cuddykid> costyn: updates automatically
[13:20] <costyn> ok
[13:21] <cuddykid> give it 30 secs, if it's not there let me know :)
[13:21] <willdude123> It'll be interesting if it goes over the channel to see if the ITU code works.
[13:21] <jcoxon> And sp9uob?
[13:21] <cuddykid> might take a little longer actually on startup now because there's so much telemetry to download
[13:21] <costyn> cuddykid: ok, it's not actually saying it's doing anything (like usually at startup)
[13:22] <cuddykid> hm, is it spinning in top right corner costyn ?
[13:22] <costyn> cuddykid: yea just saw that appear and dissapear followed by a check mark
[13:22] <mfa298> mattbrejza: just tried a different java version and it looks like it's loaded :D
[13:22] <cuddykid> ok, give it 10 secs costyn and try the flights list again
[13:22] <mfa298> now to hope the signal returns strong enough and I can try decoding
[13:22] <costyn> cuddykid: it's been 2 minutes now :)
[13:23] <cuddykid> hm, right - can you close the app and remove it from multitasking? double click home button and remove it?
[13:23] <costyn> sure
[13:23] <cuddykid> then try again - I'll have a look into it
[13:23] <costyn> ok
[13:24] <willdude123> How many receivers are there in britain?
[13:24] <costyn> cuddykid: it'd be cool, as a feature, to have a progress meter on the downloading/processing, but I'm not sure how hard that would be
[13:25] <costyn> cuddykid: hmm still no AVA, just XABEN, HABE and SR0FLY
[13:25] <cuddykid> costyn: that would be nice, problem is habitat doesn't give the size of data to be downloaded (I think - unless it's embedded in http headers)
[13:25] <cuddykid> hm, costyn let me start up mine again

[13:30] <eroomde> what did you do to it before launching it daveake?
[13:30] <costyn> Maxell: Radio resets every 20 telemetry lines.
[13:31] <willdude123> Does that mean the count restarts
[13:31] <Geoff-G8DHE> lot of fading on the signal at present

[13:33] <craag> willdude123: The RFM22 radio module has it's own computer in it, and sometimes gets into a strange mode, rebooting it resets it.
[13:34] <costyn> yea I have that on mine too. every 50
[13:34] <costyn> seems to solve it
[13:34] <Hix_> hurrah, home brew 2.4GHz birdcam is a success :)
[13:34] <costyn> willdude123: and the counter doesnt restart, it's only the radio

[13:39] <Maxell> craag: whats the 32 then?
[13:40] <craag> Maxell: 32 means gps lost lock
[13:40] <eroomde> well, there are some cold places with bad atmosphere on the ground too

[13:41] <Geoff-G8DHE> OK just getting a lot of gradual fading
[13:42] <daveake> Quite weak here now
[13:42] <craag> mattbrejza: I changed dial freq and your app didn't change to the new freq. Restarted it and it still doesn't lock on :/

[13:44] <mfa298> craag: I don't suppose your websdr is running is it ?
[13:45] <M0UPU> back
[13:45] <craag> mfa298: Not today.
[13:45] <Maxell> It's getting stronger >:)
[13:45] <craag> Dokkum globaltuner is running though.
[13:46] <mfa298> I'll have to wait to see if the signal comes back to me.
[13:46] <mfa298> Might have to give that a try then
[13:47] <craag> Hopefully getting up on Zepler roof next week to recce placement of websdr discon though :)
[13:47] <craag> *discone
[13:48] <M0UPU> the Geofence should change -F when it enters france

[13:58] <M0UPU> no problems it was an experiment
[13:59] <gonzo_> did you get any useful geofence results?

[13:59] <craag> Should still cross french coast?
[14:00] <costyn> can we still set the predictor for the landing spot?
[14:00] <M0UPU> yeah putting it on now

[14:00] <Maxell> HA! 6,0,-#,46*68A
[14:00] <Maxell> Thats geofence right?
[14:00] <eroomde> maybe it was shot down by a berk from Berck

[14:10] <costyn> shouldn't the france geofence be triggering now?
[14:11] <M0UPU> boundaries are rough

[14:13] <chrisstubbs-NSE> mfa298, when i tested my sound card on the pi with audacity recordingit was very choppy.
[14:13] <M0UPU> should report France as it clears Berck

[14:19] <DHutchkinn> i was reading through the Ukhas page and was interested in making a high altitude balloon system

[14:22] <GMT> he supposed to be!

[14:23] <GMT> what would you rather he said - ooh look, a mountain goat!
[14:23] <willdude123> Then you go, just kidding, I'll pull up.

[14:25] <M0UPU> nope
[14:25] <M0UPU> well unless one of our French chums wants to go get it
[14:25] <GMT> leave it up to you Will ...
[14:25] <DHutchkinn> so the gps module on the payload sends the data to the receiver which reflects it onto the fdigi software, so how do you get the positioning onto the website
[14:26] <willdude123> Automagically.
[14:26] <chrisstubbs-NSE> M0UPU, 64rpm
[14:26] <eroomde> DHutchkinn: the receivers on the ground have a radio receiver and a PC
[14:26] <GMT> Daveake has a supply of magic fairy dust
[14:26] <DHutchkinn> is there a link between the software and the website
[14:26] <Geoff-G8DHE> the dl-fldigi program sends it to a server for display
[14:26] <M0UPU> YEah I suspect the parachute is very very tangled if working at all
[14:27] <M0UPU> it was a big chute for a small payload
[14:27] <willdude123> DHutchkinn: We use fairies to take the GPS data to our center in Cambridge.
[14:27] <fsphil_MI0VIM> oh, it burst
[14:27] Nick change: fsphil_MI0VIM -> fsphil
[14:27] <chrisstubbs-NSE> you would think just the drag of the tangled chute would slow it up more than that
[14:27] <M0UPU> yes fsphil
[14:27] <eroomde> the fldigi software that you mentioned runs on the PC. When it sees a valid telemetry string (one which passes the test for errors) it will send that over the internet to a server that UKHAS has
[14:27] <fsphil> I thought I had time for lunch :)
[14:27] <chrisstubbs-NSE> well 10m/s isnt too bad now i suppose

[14:46] <willdude123> I reckon the beagle board would make a good modem.
[14:46] <eroomde> for the 1/4 wave with ground plane we usually fly, maybe 6dBi?
[14:46] <eroomde> if the grounding is good

[14:49] <DHutchkinn> will it be ok if you have >10dB antenna gain?
[14:49] <Geoff-G8DHE> <DHutchkinn> most aerials on the balloons are simple 1/4wave with groundplane, the payloads spin and shake so no high gain is possible, also want the signal to head earthwards so groundplane is normally inverted as to a ground station
[14:49] <mattbrejza> i suppose if you have a wide BW you wont need to do AFC and so wont need FFT
[14:50] <fsphil> I was reading about the FFT this-morning again. Suspect that's why I have a headache again
[14:50] <DHutchkinn> understood
[14:50] <fsphil> I get what it's doing, not how it does it
[14:51] <mattbrejza> yay for maths
[14:51] <eroomde> it's worth doing an example by hand on paper with say 9 samples
[14:51] <eroomde> and drawing arrows around the place for each butterflying stage
[14:52] <eroomde> 9 samples!?
[14:52] <eroomde> 8 samples
[14:52] <eroomde> sorry
[14:52] <fsphil> yes, has to be a power of 2 doesn't it?
[14:52] n8cgy (18b4fe92@gateway/web/freenode/ip.24.180.254.146) left irc: Quit: Page closed
[14:52] <fsphil> which I sorta get why
[14:52] <fsphil> I'm getting there
[14:53] <fsphil> doing it on paper is a good idea
[14:53] <eroomde> yes, so you can keep halving the sets
[14:53] <fsphil> yes
[14:53] <eroomde> until you end up with indivual ones
[14:53] <fsphil> in my head I have it doing a single wave across the sample set
[14:53] <fsphil> then dividing it, and doing the same for each
[14:53] <fsphil> etc.
[14:53] <eroomde> if you don't actually have 2^n samples for interger n, then you can just buffer the array of samples with zeros until it's big enough
[14:53] <eroomde> works just as well
[14:54] Action: eroomde mubles something about windowing
[14:54] <fsphil> yes that will create high frequency bits :p
[14:55] <fsphil> what I'm not sure about is the bit reversal thing I've seen in some C examples
[14:55] <fsphil> not sure what that is doing at all
[14:57] <eroomde> hmm, it sort of falls out if you draw the 8-sample diagram
[14:57] <eroomde> hang on
[14:59] <eroomde> http://i.imgur.com/Ld9Eild.png
[15:00] <eroomde> so to get the FT (capital X) points out in the right order, you have to shuffle then time-series samples (lower-case x) on the input
[15:01] <chrisg7ogx> sorry bout chase car symbol....using/learning about Hab tracker on my tablet
[15:02] <eroomde> hmm maybe there's a better way to explain it
[15:02] <eroomde> for a one stage of butterlying, you have the even terms and the odd terms
[15:03] <arko> Upu flying?
[15:03] <DHutchkinn> also one last question, if i had a string on the dl-fdigi, displaying lon,lat,alt, time,... and was testing it and check on the map, do i have to go through the habitat/habhub website?
[15:04] <eroomde> the over terms (x0,x2,x4,x6...) and then the odd terms (x1,x3,x5...). you can see how that would shuffle the order away from just numberical order (x0,x1,x2,x3...)
[15:04] <eroomde> sorry crap fingers - s/over/even
[15:04] f5apq (02055fe0@gateway/web/freenode/ip.2.5.95.224) joined #highaltitude.
[15:05] <eroomde> well, if you have to split the even terms up into individual DFTs and the odd terms up into individual DFTs, then the 'even terms (say x0,x2,x4,x6) themselves become a set that you have to split up into even and odd terms
[15:06] <eroomde> so x0 and x4 are the even ones (occupying the even position in that array) and then x2 and x6 become the 'odd' terms, because thuey occupy the odd positions in that array
[15:06] <eroomde> input[] = {x0, x2, x4, x6}
[15:06] <eroomde> eveninput[] = {input[0], input[2]}
[15:07] <eroomde> oddinput[] = {input[1], input[3]}
[15:07] <chrisstubbs-NSE> DHutchkinn, you have to set up a payload doc on habitat to tell the server what order your sentance is in, and what each value means
[15:08] <chrisstubbs-NSE> then a flight doc when you actually want to send it up
[15:08] <eroomde> so now you do a DFT in the eveninputs (which happen to be x0, x4) and the odd inputs (which happen to be x1, x3)
[15:08] <eroomde> i'm not sure if i'm explaining this weell
[15:09] <eroomde> but basically each array you want to DFT gets split into two arrays, one with the terms at even indexes in the first array, one with the terms at odd indexes in the first array
[15:10] <eroomde> and then you do successive splits on those new arrays too in the same way, which rejigs them into more smaller arrays of odd and even terms. and if you follow that through you end up with the reording of the original input that you started with, as in that diagram
[15:11] <eroomde> and if you look at that rejigged pattern, it just so happens that they correspond with the bits being reversed of their original index
[15:12] <eroomde> which is kind of pretty cool
[15:12] <eroomde> here endeth my hand wavy explanation
[15:15] <Geoff-G8DHE> <DHutchkinn> Not sure if I follow you, if you are "on-line" then as soon as a valid string, or even a recongnisable one is received then it is sent to the server as defined in the dl- config tabs.

[18:46] <chrisstubbs> i guess the payload still has to run at 3v3 though becuase of the RFm22b
[18:47] <Upu> no RFM22B can run at 1.8v
[18:47] <willdude123> Could you power a ublox by PWMing at 3.3v?
[18:48] <Upu> hmm ?
[18:48] <Upu> Ublox MAx6Q runs at 3.3V
[18:48] <Upu> 6G at 1.8v
[18:48] <Upu> and no you couldn't drive it via PWM for power I don't think that would work

[22:04] <lz1dev> its been hours
[22:04] <Upu> nope you probably will
[22:05] <Upu> seriously Will if that antenna had been on the roof (and I know you can't put it there just saying) you'd have probably got it all the way to France
[22:05] <daveake> Yup
[22:07] <mfa298> willdude123: it's always worth trying to recieve balloons if you're around. I didn't expect to get anything today after the balloon started to head east but I was recieving it for quite a long time after that.
[22:07] <Upu> I couldn't believe how strong the signal was on your setup
[22:08] <Upu> quite chuffed as I made that antenna :)
[22:08] <Upu> for the record my first attempt at receiving a HAB I got 3 lines from jcoxon's ATLAS
[22:09] <Upu> so you beat me
[22:09] <lz1dev> Upu: whats that balloon over kazakhstan ?
[22:09] <Upu> lz1dev that is some really dubious GPS positions :)
[22:09] Action: Upu looks at Maxell
[22:09] <lz1dev> why GO hasn't overtaken Source and 1.6
[22:09] <lz1dev> because people don't like change, and like to be stubborn about not changing and that their older debatably inferior version is better. Throw some nostalgia in there too.
[22:09] <lz1dev> erp

[22:10] <Upu> as Arko pointed out physics don't seem to apply to that one
[22:10] <Upu> well thank daveake for the antenna
[22:10] <Upu> he made it
[22:10] <Upu> was running at the 12.5db setting on the RFM22B
[22:10] <daveake> :-)
[22:11] <Upu> err
[22:11] <Upu> 12.5mW
[22:12] <Upu> interesting I had a good e-mail conversation with a very enthusiastic RF Engineer at Silabs and he was saying 1/4 waves were the way to go
[22:12] <Upu> that Si4464 has been used in cube sats
[22:12] <lz1dev> most cubesats use 1/4 waves
[22:13] <lz1dev> from what i've read
[22:13] <mfa298> 1/4 waves like that have the benefit of being easy to make and a decent radiation pattern
[22:14] <lz1dev> and their deployment mechanism is simple
[22:14] <mfa298> I started trying use eznec to see how things might perform (after the discussions a few days ago about 868/434 antennas). I probably ought to play a bit more.

[22:27] <Upu> interesting
[22:28] <Upu> just make sure the GPS antenna "hangs over" the edge
[22:28] <Upu> so its not got ground plane under it
[22:28] <Lunar_Lander> cool
[22:28] <Upu> are you getting that made as a PCB ?
[22:29] <PaulCDR> i think the antenna hangs over the edge, but think ill move it up to be sure,
[22:29] G8KNN-Jon (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) joined #highaltitude.
[22:29] <PaulCDR> yeah, getting it made as a pcb, using sprint circuits
[22:30] <Upu> which GPS module are you using ?
[22:31] <PaulCDR> the one i bought off you, ubloc6
[22:31] <Upu> ok in that case I would rotate the GPS 90'
[22:31] <Upu> so the antenna sticks out over the edge
[22:32] <Upu> other than that should work fine
[22:32] <PaulCDR> yeah, thats a good idea, it would hang out the back
[22:32] <Upu> didn't know you could do PCB in Fritzing
[22:32] <Upu> let me introduce you to Eagle sometime :)

[22:33] <Lunar_Lander> how would you mount a Sarantel on a PCB so that it sticks up vertically?
[22:33] <Upu> don't need too Lunar they work fine horizontally
[22:33] <Lunar_Lander> hm
[22:33] <PaulCDR> yeah, i tried it in eagle, not quite there yet though. fritzing lets you build it up on a breadboard then produces the PCB to set your parts
[22:34] <PaulCDR> using a motorola phone to text the location data also. serial port built into the earphone socket
[22:34] <Upu> what is Bn1 ?
[22:35] <Upu> the RF connector
[22:35] <PaulCDR> didnt label that right, just the bnc connector for the antenna
[22:35] <Upu> just an odd pad layout
[22:35] <Upu> if there is an SMA connector use that
[22:36] <Upu> you can solder directly to the PCB or put a SMA on it
[22:36] <PaulCDR> using this part from cpc http://cpc.farnell.com/te-connectivity-greenpar/1-1337542-0/socket-bnc-ins-pcb-50r-white/dp/CN14901
[22:37] <PaulCDR> sma would be a lot smaller too i suppose
[22:37] <Upu> will work BNC's seem over kill for this
[22:37] <Upu> the LCD connector is right over the USB header so just check the pins don't stick down and short on the USB header
[22:37] <Upu> likewise your GPS is close to the ICSP header
[22:37] <Upu> on a Duemilanovo anyway

[22:45] <arko> oh wow
[22:45] <Upu> had a nice flight path mattbrejza
[22:45] <arko> what was the payload mass?
[22:45] <Upu> 100g
[22:45] <PaulCDR> yeah, upu, i think your right about the lcd location
[22:45] <Upu> 55g which was parachute :/
[22:45] <arko> dude, thats pico for murica
[22:45] <mattbrejza> its like it went on a tour of places ive been to

[22:47] <arko> wow thats slow
[22:47] <Upu> last one we did at 2m/s floated at 39km
[22:47] <Upu> this burst at 39km
[22:47] <Upu> it happens
[22:47] <mattbrejza> i would have expected it to start to level off a 33km but it kept stretching and going up
[22:48] <Upu> no we expected it to float at 39km
[22:48] <Upu> it did start to slow at 39km
[22:48] <arko> interesting
[22:48] <Upu> ascent rate
[22:48] <Upu> as you'd expect
[22:48] <mattbrejza> maybe a bit slower ascent next time?
