[00:00] <AL0I_Todd> PBH -18 sendiing telemetry now
[00:00] <AL0I_Todd> Very weak
[00:00] <AL0I_Todd> on 30M
[00:00] <Upu> whats your QSL AL0I_Todd ?
[00:01] <Morseman_G0DJA> OK jcoxon I'll try and find it - GN
[00:01] <AL0I_Todd> I'm in Boone, NC, USA
[00:01] <Upu> ok
[00:01] <Upu> anyone noticed PBH is consistantly decending
[00:01] <Upu> ?
[00:02] <Dan-K2VOL> yes, it's the sunset loss of lift
[00:02] <Upu> so it should settle ?
[00:02] pjm (~pjm@ joined #highaltitude.
[00:02] <Dan-K2VOL> yes, it will sink until it drops ballast or until the sun comes up
[00:02] <Dan-K2VOL> or until the water comes up
[00:02] <Upu> haha
[00:02] <Dan-K2VOL> whichever comes first
[00:02] <Lunar_Lander_> is there info on the payload?
[00:02] <Lunar_Lander_> xD
[00:02] <Dan-K2VOL> PBH is always tight-lipped about their stuff
[00:03] <Upu> I'm glad you're more open about your project Dan
[00:03] <Lunar_Lander_> yeah
[00:03] <Lunar_Lander_> is that because of Lockheed?
[00:03] <Dan-K2VOL> well

[00:04] <Dan-K2VOL> honestly they're training lockheed systems engineers, and publishing the specs to the public won't be in their job description when they get back to the job
[00:04] <Upu> yeah understood
[00:04] <Dan-K2VOL> so I don't really blame them, they aren't secretive if you ask them directly, but they just don't take time to publish
[00:04] <Lunar_Lander_> yea
[00:04] <Lunar_Lander_> but I never found an e-mail on their site
[00:04] <Dan-K2VOL> I've had coffee and many phone calls with John, the director there, nice guy.

[00:05] <Dan-K2VOL> haha upu you're awesome
[00:05] <Upu> ribbon cable is because I can't afford the crimpers atm
[00:05] <Morseman_G0DJA> OK so if they don't want to tell me what/where then I'm stupid to be up this late looking for their balloon?
[00:06] <Morseman_G0DJA> DOH! - Good night
[00:06] <Upu> nn :)
[00:06] <jonsowman> Upu: that's amazing
[00:06] <Dan-K2VOL> it really is!
[00:06] <Upu> its not perfect
[00:06] <Lunar_Lander_> good night
[00:06] <Upu> nn LL
[00:06] <Lunar_Lander_> no
[00:06] <Upu> I'd redoing it
[00:06] <Lunar_Lander_> good night Morseman_G0DJA
[00:06] <Dan-K2VOL> how's the weight?
[00:06] <Lunar_Lander_> I meant
[00:06] <Lunar_Lander_> Upu,
[00:06] <Upu> err not a lot
[00:07] <Upu> it doesn't work from 1 AAA due to the step up inefficiency
[00:07] <Lunar_Lander_> yea
[00:07] <Upu> so going to have to put 2 cells on it
[00:07] <Upu> it *should* work
[00:07] <Lunar_Lander_> are there really AAAA batteries btw?
[00:07] <Upu> but it doesn't
[00:07] <Randomskk> Upu: step ups are tricky buggers
[00:07] <jonsowman> Upu: that's a shame
[00:07] <Randomskk> you might be able to change inductors or layout to make it wokr
[00:08] <Upu> its 7g without the batteries
[00:08] <Upu> I think 2 x AAA is the way to go
[00:08] <Randomskk> yea probably
[00:08] <Upu> so designing it round that, might be a little larger
[00:08] <Randomskk> better capacity that way too
[00:08] <Upu> yeah
[00:09] <Upu> and if you want to power it from something else just don't put the battery clips on
[00:09] <Lunar_Lander_> are there really AAAA batteries btw?
[00:09] <Dan-K2VOL> is that an energizer lithium AAA though?
[00:09] <Upu> yes Dan-K2VOL
[00:09] <Upu> not aware of AAAA Lunar_Lander_
[00:09] <Lunar_Lander_> ok

[08:17] <Graeme_SHARP> (Not me - Andrew that is)
[08:18] <Graeme_SHARP> Haha Dave. Must have been classic!
[08:19] <daveake> Well my launch site is 200m from home, so no problem
[08:25] <navrac> hi daveake - you got your payload back then. Was it far across the fields to get it
[08:29] <daveake> Took a while to find which field. We lost the internet connection and the telemetry and we didn't have a local paper map.
[08:29] <daveake> Evenetually we got a map up showing the roads near where we thought it was, so we made our way closer and then started to pick up the signal.
[08:30] <daveake> This was very rural and I think someone called the police because a police 4z4 turned up to ask what we were doing!
[08:30] <Dutch-Mill> Morning Y'all Graeme_SHARP what's the expected altitude ?
[08:30] <daveake> Once we had a fix we put that into my phone for directions.
[08:31] <Graeme_SHARP> Morning Dutch, not that high, around 26-28km likely. If we go any higher we start getting dangerously close to gatwick!
[08:31] <navrac> we did wonder how you were going to find it whaen we lost the chase car signal and reckoned you were in a no mobile zone
[08:31] <daveake> Got to the road nearby, went back and forth till the position on the phone was as close as we could get to the payload.
[08:31] <daveake> Then found somewhere to park and headed out with torches
[08:32] <navrac> how the the police?
[08:32] <daveake> Followed a track by and through the field and it was right next to that
[08:32] <navrac> were
[08:32] <daveake> Oh fine
[08:32] <daveake> "We're chasing a balloon"
[08:32] <daveake> [confused look]"OK, have fun"
[08:32] <navrac> didnt ask you to bloww in one of theirs when you said that
[08:32] <daveake> 5 mins later a "security" 4x4 turns up
[08:32] <daveake> "Oh, are you the ones chasing a balloon?"
[08:33] <daveake> "Yes"
[08:33] <daveake> "Seeya"
[08:33] <daveake> navrac no lol
[08:34] <navrac> was it one balloon deflated as we suspcted?
[08:34] <daveake> yes
[08:34] <Dutch-Mill> Oke thanks that's high enough... standby for tracking
[08:34] <navrac> burst or leak
[08:35] <daveake> Not looked closely but it was still partially inflated but the gas escaped as I squeezed
[08:35] Graeme_SHARP (~Graeme_SH@ left irc: Ping timeout: 244 seconds
[08:35] <number10> paload damaged or was there enough gas in it
[08:35] <number10> to land lightly
[08:35] <daveake> Payload fine
[08:35] <navrac> hmm, i wonder if pico floating is just a case of luck rather than design.
[08:36] <navrac> I think i might try to replicate ozzie to see if its repeatable or leaks
[08:37] <navrac> or possibly it was the fast ascent rate that saved it - so it didnt so high so it didnt burst.
[08:38] <navrac> but then it had more gas in to start so surely higher pressure.
[08:38] <navrac> I need to think more on this
[08:38] <daveake> Yeah, I was confidently expecting mine to float with that ascent rate
[08:39] <navrac> so was i - funnily the first drop looked like night cooling - very similar to ozzies curve
[08:39] <navrac> so the second step change happened at a lower height
[08:39] <navrac> strange

[09:35] <Upu> any plans to get it out ?

[09:35] <Upu> ineeed
[09:36] <Upu> indeed

[09:38] <Graham_G3VZV> thats interesting - there is a bit of a lift on 70cms this morning and there is a strong ?Dutch FM station coming thru on 434.650MHz

[11:56] <jcoxon> thats what twitter reports

[11:58] <Laurenceb_> oh wow
[11:58] <Laurenceb_> i didnt know that
[11:58] <Laurenceb_> thats slightly odd
[11:58] <radicalbiscuit> how so?
[12:00] <Laurenceb_> well when the solar heating goes youd expect it to drop and keep dropping
[12:01] <Laurenceb_> the altitude profile looks like they dropped ballast
[12:01] <Laurenceb_> oh wait - polythene envelope?
[12:01] <navrac> no - not necessarily - the temp stabilises so a balance is found
[12:01] <Laurenceb_> as long as its not superheated itll lose lift
[12:01] <navrac> interesting is how much it recovers when solar heating starts - ie the loss of he overnight
[12:01] <Laurenceb_> but it might be absorbing some IR from the ground
[12:02] <Laurenceb_> e.g. gulf stream in the ocean
[12:02] <Laurenceb_> its laready hit daybreak

[14:58] <Colin-G8TMV> ok, I have it here in Cambridge
[14:58] <Graham_G3VZV> yup
[14:58] <Udin_SHARP_> yep we are up
[14:58] <daveake> got one
[14:58] <Colin-G8TMV> .648.22
[14:58] <Udin_SHARP_> sorry about the delay
[14:58] <daveake> Oh, sentence duplicated?
[14:58] <Colin-G8TMV> yup 40 secs of the same thing then 20 secs of silence
[14:59] <Graeme_SHARP> Launch!
[14:59] <Colin-G8TMV> Graham_G3VZV: old news
[14:59] <Colin-G8TMV> I'm tracking
[14:59] <Upu> lol
[14:59] <Lunar_Lander_> daveake can hear it too says the tracker
[15:00] <daveake> Yeah, nice and clear
[15:00] <fsphil-laptop> I can hear birds tweeting
[15:00] <daveake> However ... leaving Tx off completely for several seconds is going to be a pain when it drifts
[15:01] <Upu> trackers doing silly things with names again
[15:01] <Upu> ping jonsowman
[15:01] <daveake> As it stands I lose the first sentence when it comes back on
[15:01] <Colin-G8TMV> yup
[15:01] <fsphil-laptop> no preamble?
[15:01] <Colin-G8TMV> daveake: they need the window for uplink
[15:01] <daveake> The tx takes a moment to get on frequency
[15:01] <Upu> can see it in Yorkshire
[15:01] <Colin-G8TMV> but an extra few $'s or dots would have helped
[15:01] <Matt_soton> oh it duplicates, surely better to get a new GPS posistion and send that instead :/
[15:01] <fsphil-laptop> definitely
[15:01] <daveake> Understood
[15:01] <priyesh> got it too
[15:02] <pjm> copying in poole
[15:02] <daveake> Just got a good sentence but "upload failed"
[15:02] <daveake> OK this time 1st sentence was fine
[15:03] Nick change: number10 -> number10_M0MDB
[15:03] Nick change: Upu -> Upu_2E0UPU
[15:03] <Matt_soton> oh its going home :P
[15:03] Nick change: fsphil-laptop -> fsphil_2I0VIM
[15:04] <Upu_2E0UPU> massive gap
[15:05] <Matt_soton> hmm needs more preamble
[15:06] <Matt_soton> the case is supposed to keep the payload >0 so hopefully we wont need to retune
[15:06] <Colin-G8TMV> does anyone know how to fix the list of Rx's on the tracker again?
[15:06] <Upu_2E0UPU> yeah DanielRichman but not sure he's about
[15:06] <jonsowman> hi Upu_2E0UPU, what's up?
[15:06] <Upu_2E0UPU> decoding it from Yorkshire
[15:06] <Upu_2E0UPU> hi jonsowman same issue as yesterday
[15:06] <number10_M0MDB> not too sure daniel know exactly how the list came back

[15:08] <jonsowman> Upu_2E0UPU: i'm not in a position to fix at the moment
[15:08] <Lunar_Lander_> got a question if possible?
[15:08] <Colin-G8TMV> DanielRichman thought it was something to do with dupes of packets and with sharp xmitting dupes it's made it worse
[15:08] <jonsowman> not that i even know what to do
[15:08] <Upu_2E0UPU> not a problem jonsowman
[15:08] <jonsowman> since DanielRichman fixed it yday
[15:08] <Lunar_Lander_> what does "Cutdown: 9650" mean?
[15:08] <Lunar_Lander_> as I read that the cutdown has been removed
[15:08] <Upu_2E0UPU> I should do a bug request for it really

[15:43] <fsphil_2I0VIM> isn't it ironic calling a balloon project "sharp"
[15:43] <F6AGV> GPS is out on SHARP BALLOON ?
[15:43] <Graeme_SHARP> We do and there is a second transmitter that just pulses and should last a day or so.
[15:43] <daveake> Good! I have my yagi in the car too :)

[15:45] <Colin-G8TMV> Hmm.. GPS packed up at 12000 m - is that some sort of lock-out height?
[15:45] <andrew_apex> Bob: we're wondering if the aerial has got too cold
[15:45] <benoxley> andrew_apex: too cold?
[15:45] <andrew_apex> The gps aerial is active
[15:45] <x-f> what GPS is it?
[15:45] <Graeme_SHARP> Datasheet say 50km lockout, so shouldnt do!
[15:46] <Colin-G8TMV> some sort of active ant?
[15:46] <priyesh> Colin-G8TMV: isn't the lockout alt 18km?
[15:46] <Bob_G8NSV> wouldnt think that would stop it its just an amplifier cooling thiose normally improves the noise fig

[15:48] <daveake> Graeme_SHARP - Do you know if the ublox was switched to flight mode?

[15:49] <Colin-G8TMV> priyesh: ok, I assumed that if the server accepted them then they would count for chaser stats - after all they are valid if the checksum is ok

[15:52] <DeaneyBabey> Probably a good think the cutdown went when it did! Altitude of 12000 to 0 is more than your 500m drop to cut the balloon...
[15:52] <Graeme_SHARP> Deany, we'd taken account of that.

[16:17] <mfa298> Let me know if another tracking vehicle might be of use there might be a few from soton who can join in.
[16:17] <junderwood_M0JCU> I seem to recall that if a uBlox is in the wrong mode above 12 km, it will try to work out a position at about 12km altitude. Sometimes it manages, others not.
[16:17] <fsphil_2I0VIM> burst?

[16:33] <jcoxon> it'll come back

[16:44] <Udin_SHARP> ok it seems that it is going up very slowly now
[16:44] <Udin_SHARP> is that to be expected?
[16:44] <Upu_2E0UPU> no
[16:44] <Upu_2E0UPU> should be consistent
[16:44] <Udin_SHARP> because our predictions had the burst in about 10m at 28k
[16:45] <Udin_SHARP> and we are only at 21k now
[16:45] <Udin_SHARP> so pressure reading might be wrong
[16:45] <Upu_2E0UPU> actual accent rate might be slightly lower
[16:45] <upix> Udin_SHARP: could it be the pressure sensor. maybe it's not getting accurate measurement on low pressure
[16:45] <Upu_2E0UPU> usually +/- 1000 meters ?
[16:45] <Lunar_Lander_> what pressure sensor do we have?
[16:46] <Upu_2E0UPU> just shy of 20k
[16:47] <Lunar_Lander_> that disagrees with the extrapolation from the ascent rate
[16:47] <Lunar_Lander_> strange
[16:47] <Udin_SHARP> yes
[16:47] <Lunar_Lander_> the extrapolation has it near 30k

[17:29] <Graeme_SHARP_Mob> It should be transmittin some CW on 433.921 aswell.
[17:30] <Graeme_SHARP_Mob> 923*
[17:30] <Colin-G8TMV> there is something there - but it isn't cw
[17:31] <r2x0t> 433.92 is frq for OOK transmitters for temperature sensors and other stuff
[17:31] <Matt_soton> all i heard on 433.92 was a whole load of crap
[17:32] <Graeme_SHARP_Mob> Its a bird tracker just repeating a phrase, our back up for direction finding it. :)

[17:38] <pjm> nearly hit the wife on the head
[17:38] <upix> :D
[17:39] <upix> how did they manage to land so accurately
[17:39] <upix> or did u join this channel after that

[17:41] <benoxley> got a final lat/long?
[17:41] <Matt_soton> paste the gps coordinates?
[17:41] <pjm> upix it was a weather sonde, not ham payload ;-)
[17:41] <upix> pjm: oh :D
[17:42] <upix> did you give the zond back?

[17:45] <fsphil-laptop> the gps is not a complete unit
[17:45] <Matt_soton> http://g.co/maps/6nzwv
[17:45] <r2x0t> also I think pressure sensor would be reusable
[17:45] <r2x0t> if you recallibrate it
[17:45] <fsphil-laptop> it doesn't transmit position - it I think transmits the phase of the gps signals
[17:45] <Matt_soton> the GPS is a helicodal thing tahts part of the main pcb
[17:45] <fsphil-laptop> or something like that
[17:45] <r2x0t> yes, it doesn't have full gps
[17:46] <r2x0t> only sends pseudoranges
[17:46] <upix> what about parachute
[17:46] <Matt_soton> it has a small one
[17:46] <r2x0t> depends on where they launch it
[17:46] <upix> you can use many... :D
[17:46] <r2x0t> some use chutes
[17:46] <r2x0t> some dont lol
[17:47] <Udin_SHARP> both teams should be within 200m
[17:47] <upix> how many deaths are there by those zonds
[17:47] <r2x0t> decoded sonde going down 80m/sec
[17:47] <r2x0t> that would hurt

[18:03] <priyesh> with a yagi
[18:04] <r2x0t> going for a signal with yagi would be better
[18:04] <mfa298> if they've got the yagi on something portable it should be possibly to DF it.

[18:40] <Bob_G8NSV> very dificult as pocsag pagers are on 138mhz and the stuff i want to hear is on 137!
[18:40] <Lunar_Lander_> we need to set the hex commands for the airborne mode in void setup() when using arduino
[18:41] <Lunar_Lander_> but I heard that it might be that the ublox can restart or so
[18:41] <Lunar_Lander_> has the command to be moved to the loop?
[18:41] <jcoxon> it doesn't reset with the airborne code
[18:41] <jcoxon> Lunar_Lander_, you can check the ublox is set correctly

[19:00] <Randomskk> because depending on how you want to cost it I can think of some pretty expensive payloads ;)
[19:01] <Matt_soton> ok, standard launches only :P
[19:01] <Randomskk> :P
[19:01] <Matt_soton> case materials were >£240 for a start

[19:02] <Matt_soton> or am i making that up :\
[19:02] <Upu> James May had 3 per payload
[19:03] <WB8ELK> I flew 4 GoPros last April....Up Down and two horizon ones
[19:03] <jonsowman> i think the ESA vehicle wins this game
[19:04] <Matt_soton> just because of the camera?
[19:04] <Matt_soton> what else was on board?
[19:04] <jonsowman> the whole thing was custom built
[19:04] <LazyL_M0LEP> That an "add a few zeros" price tag?

[19:04] <Randomskk> and the parachutes
[19:05] <Randomskk> which were also custom
[19:05] <jonsowman> i would guess at about £5-7k
[19:05] <Randomskk> and the main flight computer which was in the triple digits for parts alone
[19:05] <Randomskk> the pyrotechnics were not cheap

[19:09] <WB8ELK> I did copy the altitude...it's at 31500 meters
[19:09] <Matt_soton> tbh that processor would have put out no more heat then smart phone launches, it wasnt that powerful
[19:09] <jcoxon> i got 2XE S N EODU6 316 E EE E M6
[19:09] <Matt_soton> what power is it putting out?
[19:09] <NSS-WB9SBD> 30 meters? what tims now is it transmitting at?
[19:09] <WB8ELK> so 31600 meters now
[19:09] <WB8ELK> 00, 20 and 40 minutes past
[19:10] <WB8ELK> 10.145 USB will put it about 1580 Hz in the waterfall display
[19:10] <NSS-WB9SBD> OK, any idea of lt long?
[19:10] <WB8ELK> about 35 seconds each transmission
[19:10] <WB8ELK> sometimes sends a second frame a minute later
[19:11] <NSS-WB9SBD> Seemed to have dropped bit in freq.
[19:11] <WB8ELK> not really...still 1014658
[19:11] <WB8ELK> hasn't shifted much since I started to copy it last night
[19:11] <NSS-WB9SBD> oops duh he he he
[19:12] <WB8ELK> my ears are ringing....tough pulling that data out with the volume up full
[19:12] <NSS-WB9SBD> that noise was driving me nuts,
[19:12] <WB8ELK> hop onto the Nova Scotia GlobalTuners radio....James is there with me at the moment
[19:13] <WB8ELK> they are much weaker than the last time they flew
[19:13] <NSS-WB9SBD> the noise reminded me of the sound on the 7UP commercial that lttle CEE-LO Greene mkes when he was small and his ma opens up a can of 7UP.
[19:13] <griffonbot> Received email: "Re: [UKHAS] Solar balloon volume query"
[19:13] <WB8ELK> I had to record each frame and play it back several times to extract the data
[19:14] <WB8ELK> at sunrise it got to a decent signal strength but had to go to bed at that point
[19:14] <jcoxon> WB8ELK, whats the solution do you think
[19:14] <NSS-WB9SBD> 6 inutes I'll see if I hear it directly, band is pretty quiet right now, ahh the "MT" is being transmitterd again.
[19:14] <jcoxon> wow that was strong
[19:14] <WB8ELK> better antenna match?
[19:14] <jcoxon> more often tx'ing
[19:14] <WB8ELK> that was their ground station sending a command for a status update
[19:15] <upix> is there another baloon?
[19:15] <daveake> Home :)
[19:15] <WB8ELK> at least every 10 minutes and repeat each transmission
[19:15] <jcoxon> do you think hellschreiber would help?
[19:15] <NSS-WB9SBD> I was last night thinking it was "Ballast Dump"
[19:15] <WB8ELK> DominoEX would be the way to go at those signal levels
[19:16] <jcoxon> WB8ELK, when are you going to launch?
[19:16] <WB8ELK> Hellscreiber would work as well but not as low into the noise as DominoEX
[19:16] <NSS-WB9SBD> Agreed,
[19:17] <WB8ELK> We're launching 5 student balloons in a row next Saturday...so I'll probably fly my long duration after that...I'll be testing my Iridium modem on one of those
[19:17] <jcoxon> i really want to test the dl-fldigi/spacenear.us with a long flight
[19:18] <NSS-WB9SBD> long as in distance or duration?
[19:18] <WB8ELK> I will be contacting you about how to link my Iridium data to spacenear....I looked over your Perl code but have some questions about how to do that on a Windows machine
[19:18] <jcoxon> oh it'll be easy

[19:18] <jcoxon> NSS-WB9SBD, well an HF flight like this
[19:18] <WB8ELK> I'll have 30 meters on it as well

[19:28] <jcoxon> upix, confusion regarding position
[19:28] <upix> ah
[19:28] <fsphil-laptop> I wonder why they didn't use a frequency agile radio
[19:28] <fsphil-laptop> or do they have weight limits?
[19:30] <upix> I have some questions hoping you could help with. The problem is with getting a decent radio tranceiver as expenses is a major concern. So I am thinking of something like putting a more powerful transmiter and catching signal with a handheld radio. I assume the radio would be FM and so does anyone have an idea how powerfull should the transmitter be if chase team could be in ~50km radius. Any other alternative suggestions are welco
[19:32] <WB8ELK> I'll be flying a frequency agile transmitter in a week or two
[19:32] <WB8ELK> I still think it was -46 deg W....not sure...it took a fade
[19:33] <fsphil-laptop> the rfm22b might be an option upix -- the range seems to be quite good, but it hasn't been well tested
[19:33] <WB8ELK> it might be -36
[19:33] <jcoxon> we can confirm in 7 minutes
[19:33] <WB8ELK> yep
[19:33] <fsphil-laptop> I must fire up my radio, solar inverter is off now
[19:33] <jcoxon> i'm suprised if its -36

[19:36] <upix> manchester? I am not from UK :)

[21:45] <Lunar_Lander_> this one
[21:45] <Lunar_Lander_> Elmar_PD3EM, Dan-K2VOL http://groups.google.com/group/ukhas/browse_thread/thread/fffc57345ee85b38
[21:46] <Elmar_PD3EM> Lunar_Lander_: I haven't received any further news/info from them...
[21:47] <Lunar_Lander_> ah ok
[21:47] <Lunar_Lander_> thanks
[21:47] <Elmar_PD3EM> Lunar_Lander_: Maybe you can ask Bill N5VEI for more info
[21:48] <Dan-K2VOL> he follows me on twitter lunar lander, Bill Richardson
[21:48] <Dan-K2VOL> i'm @steamfire
[21:48] <Dan-K2VOL> er he may be following the @LVL1WhiteStar, let me check
[21:49] <Lunar_Lander_> OK
[21:49] <Lunar_Lander_> I have to open a twitter account once I think
[21:49] <Dan-K2VOL> he's @n5vei
[21:49] <Elmar_PD3EM> Dan-K2VOL: now following you from @PD3EM ;-)
[21:49] <Dan-K2VOL> :-)
[21:50] <Dan-K2VOL> got you too
[21:50] <Elmar_PD3EM> haha...
[21:51] <WB8ELK> sunset now on PBH....it has dropped to 30000m now
[21:51] <Elmar_PD3EM> got to go... it's 1 hour later than I think it is.... #$#@ Summertme, allmost midnight now
[21:51] <WB8ELK> Yes...Bill N5VEI....he also flew one of my 20 meter multi-mode transmitters
[21:52] <WB8ELK> it transmits sometimes at 45 minutes past the hour for some reason
[21:52] <WB8ELK> it also shifted 1000 Hz lower in frequency during the last transmission
[21:54] <Lunar_Lander_> was that the Pell City flight?
[21:55] <Lunar_Lander_> or the two Pell City flights of which the first landed in the atlantic ocean
[21:55] <Lunar_Lander_> I mean what is said in the google groups list
[21:55] <Elmar_PD3EM> good night all ! 73
[21:56] <Lunar_Lander_> good night Elmar_PD3EM

[22:05] <WB8ELK> hi Dan
[22:05] <WB8ELK> and Todd
[22:06] <AL0I_Todd> Hey Bill
[22:06] <WB8ELK> I heard it all night long but was at the noise level
[22:06] <WB8ELK> only hearing it via the Nova Scotia GlobalTuner at the moment
[22:07] <AL0I_Todd> The last hour has been the best reception I have had. Shifted dipole antenna to East-West orientation at 2100 UTC.
[22:07] <WB8ELK> good...maybe I'll start to hear it here soon

[22:20] <Lunar_Lander_> back home?
[22:20] <Udin_SHARP> yep
[22:20] <Udin_SHARP> or mission control as it was called today
[22:22] <Lunar_Lander_> ah
[22:22] <Lunar_Lander_> and you got everything back
[22:22] <Lunar_Lander_> :)
[22:23] <Udin_SHARP> yes we picked up all the hardware
[22:23] <Udin_SHARP> and have a couple of bugs to fix

[22:28] <Lunar_Lander_> yeah
[22:28] <Lunar_Lander_> with the same hardware?
[22:29] <Udin_SHARP> yes
[22:29] <Lunar_Lander_> ah
[22:29] Wil5on (~Wil5on@compsci.adl/eternalpresident/wil5on) joined #highaltitude.
[22:29] <Udin_SHARP> fresh batteries though
[22:29] <Lunar_Lander_> hopefully the GPS works correctly that time
[22:29] <Lunar_Lander_> yeah :)
[22:29] <r2x0t> so 2nd try to get it on tree :)
[22:30] <r2x0t> hope you fix that GPS, otherwise it was good flight
[22:30] <Udin_SHARP> :)
[22:30] <r2x0t> maybe also updating position more often then once a minute?
[22:30] <Udin_SHARP> Well there were a couple of other issues
[22:31] <navrac> any idea of launch time (ish) so i can fire up the receiver
[22:32] nickle (5d608f53@gateway/web/freenode/ip. left irc: Ping timeout: 245 seconds
[22:33] <Udin_SHARP> navrac from our past experience it is probably better to not make too many assumptions about launch time
[22:33] <Udin_SHARP> but we will aim to leave Southampton at the same time as today
[22:33] <navrac> well i was going to add a couple of hours on... i waited for todays but had to leave in the end so missed it
[22:33] <Udin_SHARP> so if we have less to sort out on launch site we will launch earlier than today
[22:34] <Udin_SHARP> sorry about that navrac
[22:34] <navrac> well second time will be a lot easier - you will have found at least 3 of the 100 ways a launch can go wrong!
[22:35] <Udin_SHARP> Well technically today was our 2 and a half time
[22:35] <Udin_SHARP> actually 3.5
[22:37] <Udin_SHARP> but as a guideline navrac
[22:38] Nick change: heathkid|2 -> heathkid
[22:38] <Udin_SHARP> our launch window closes after 4pm ish so we will launch before that
[22:39] <Randomskk> is that "ish" or "ISH"? :P
[22:39] <NigeyS> lol
[22:39] <NigeyS> hey Adam
[22:39] <Randomskk> heya :p how's it?
[22:39] <NigeyS> argh checksums...
[22:39] <NigeyS> need i say more? :D
[22:39] <Randomskk> hehe
[22:39] <Randomskk> what kind?
[22:39] <Randomskk> checksums are great :P
[22:40] <NigeyS> fletcher 8 bit for ublox, trying to do them without a copy/paste job, failing to see a pattern though
[22:40] <Randomskk> ?
[22:40] <Randomskk> are you writing code for them or what?
[22:40] <Randomskk> you can just copy the C code they give as an example, that's pretty canonical fletcher
[22:40] <NigeyS> well im doing same as what jons done for joey
[22:40] <Randomskk> didn't he just copy it?
[22:41] <NigeyS> turning off all the gps crap and polling indiv commands
[22:41] <Randomskk> ah right
[22:41] <Randomskk> yea, that's what I did on wombat :P
[22:41] <Randomskk> afaik joey copied the wombat checksum code
[22:41] <Randomskk> and wombat copied the ublox manual
[22:41] <Randomskk> it's a lot better like htis
[22:41] <NigeyS> hah i got the manual etc, itll sink in soon!
[22:41] <Randomskk> way way easier to parse plus you don't have to wait for it to send you stuff
[22:41] <Randomskk> still, the checksum bit should be easy
[22:41] <NigeyS> exactly
[22:41] <NigeyS> im just dumb heh
[22:41] <Randomskk> https://github.com/adamgreig/wombat/blob/master/misc/ubx_checksums/chk.c
[22:42] <Randomskk> that was my example code to calculate the checksum for a given four byte message (for polling)
[22:42] <NigeyS> thats the 1, i was going the whiteboard manual route though
[22:42] <Randomskk> though the same C works fine to calculate checksums on the fly if you wanna do that
[22:42] <Randomskk> how come?
[22:42] <Randomskk> oh
[22:42] <Randomskk> trying to work out what it's doing would be a total pain, it really is just an iterative thing
[22:42] <NigeyS> mainly to give myself a bit more understanding of how it works
[22:42] <Randomskk> ah
[22:42] <Randomskk> good luck with that :P
[22:43] <NigeyS> haha not as easy as i thought
[22:43] <Randomskk> I don't think it's entirely obvious why it's a strong checksum without fairly rigorous maths
[22:43] <NigeyS> looking that way, and im really not good at maths
[22:43] <Randomskk> it doesn't obviously mix up the input data
[22:44] <Randomskk> I would just implement it and be safe in the knowledge that in theory it's good :P
[22:44] <NigeyS> what i couldnt figure...
[22:44] <NigeyS> is how on 1 of the commands the checksum has a letter
[22:44] <NigeyS> like D
[22:44] <Randomskk> the checkum is hexadecimal
[22:44] <Randomskk> it's two bytes, so four hex digits
[22:44] <NigeyS> ahhh
[22:44] <Randomskk> (same as the CRC16 we use)
[22:44] <Randomskk> (CRC16 is a bit more fun to do on a whiteboard once you understand how the structure of it works, btw)
[22:44] <Randomskk> (but still very messy and complicated)
[22:44] <NigeyS> ok so maybe doing it in my head just isnt going to work lol
[22:45] <Randomskk> well you can do hex in your head
[22:45] <Randomskk> or you could do it decimal and then convert
[22:45] <Randomskk> but it's probably not worth doing
[22:45] <NigeyS> true, at least know how the commands are made up, and what bit does what i guess, so not a total failure
[22:47] Udin_SHARP (59f3cf18@gateway/web/freenode/ip. left irc: Ping timeout: 245 seconds
[22:47] <Randomskk> yup
[22:47] <NigeyS> how much do i regret not listening in school right about now! :/
[22:48] <Randomskk> meh, if schools taught it like this it'd be way more interesting and I'd be way happier to pay attention
[22:50] <NigeyS> couldn't agree more
[22:51] <SpeedEvil> School is largely a failure.
[22:51] <Randomskk> well - depends on your criteria for success
[22:51] <SpeedEvil> It teaches you minutia which you will lose in a few months of not using it.
[22:51] <Lunar_Lander_> are you just discussing the GPS checksum?
[22:51] <SpeedEvil> To a large degree.
[22:51] <Lunar_Lander_> yea
[22:51] <navrac> isnt the gps checksum a single digit?
[22:51] <Randomskk> not NMEA checksums
[22:52] <Randomskk> UBX checksums
[22:52] <Randomskk> which are fletcher-16
[22:52] <Lunar_Lander_> which means?
[22:52] <Randomskk> it's a different algorithm to calculate a checksum
[22:52] <navrac> using remote desktop how do you swap to the second monitor? anyone remember?
[22:52] <Randomskk> NMEA uses XOR
[22:52] <Randomskk> we often use a specific CRC-16
[22:52] <Randomskk> UBX uses fletcher-16
[22:52] <Randomskk> there are others
[22:53] <NigeyS> navrac: good question!
[22:53] <Lunar_Lander_> ah
[22:53] <Lunar_Lander_> that CRC16 I have seen in some codes
[22:53] <Lunar_Lander_> is that the thing that does the checksum?
[22:53] <navrac> i wrote a quick checksum calculator for the ublox - but the program opensd in the wrong window

[23:00] <NigeyS> bah you beat me!
[23:00] <Lunar_Lander_> ?
[23:00] <Lunar_Lander_> anyone could answer the question?
[23:01] <NigeyS> it calculates the checksum yup
[23:02] <Lunar_Lander_> yea
[23:02] <Lunar_Lander_> I need the one page on the wiki, right
[23:03] <Lunar_Lander_> the one with shows how the string has to be
[23:09] <navrac> When I get 5 minutes I'll stick some kind of front end on it and puit a link on the wiki
[23:10] <navrac> at the moment you enter the values in the source code which isnt pariculary efficient - but as a programmer thats just as easy for me
[23:10] <navrac> right bed time for me

[23:48] <AL0I_Todd> Reception here (Boone, NC) has gotten worse since 2300 UTC
[23:49] <AL0I_Todd> PBH-18 flight team was telling some idiot to stop sending commands to the balloon. The offending party stepped on the last status message.
[23:50] <AL0I_Todd> This was on 30 meters about 2342 UTC.
[23:50] <natrium42> haha
[23:50] <Lunar_Lander_> someone else has the command set?
[23:50] <AL0I_Todd> Well, I doubt it, but you can hear the flight team sending commands, so anybody can parrot the commands.
[23:51] <AL0I_Todd> Somebody sending commands now on 30M
[23:51] <Lunar_Lander_> yea
[23:51] <Lunar_Lander_> would it be better if they'd ecrypted their commands or so
[23:51] <Lunar_Lander_> ?
[23:52] <AL0I_Todd> Anybody can still hear them, and there is no way to stop somebody from sending them.
[23:54] <Randomskk> AL0I_Todd: that's not really how encryption works though
[23:54] <Randomskk> you entirely could encrypt the commands in a way that stopped other people sending them
[23:54] <Randomskk> however, you're not allowed to send encrypted data under an amateur radio license
