[08:16] <daveake_> lol
[08:16] <Upu> The safe temperature range for a NiCd battery in use is between 20°C and 45°C.
[08:17] <Upu> from Wikipedia...
[08:17] <daveake_> I know ... I read that just now :)

[09:00] <Darkside> hahaha

[09:01] <daveake_> Launch(es) today RocketBoy?
[09:01] <RocketBoy> soon say 45mins
[09:01] <daveake_> cool :)
[09:01] <LazyLeopard> Two on the tracker now. ;)
[09:01] <RocketBoy> 800g balloons
[09:01] <SpeedEvil> RocketBoy: :)
[09:02] <LazyLeopard> ...though header is still saying PICO.
[09:02] <daveake_> I'm too lazy to look on the tracker, LazyLeopard
[09:02] <Colin-G8TMV> the tracker still has the info panel for Picoatlas - where is the data for the current launch? (apart from in email)
[09:03] <LazyLeopard> http://ukhas.org.uk/general:upcoming_launches ?
[09:03] <Colin-G8TMV> are the payload systems running yet? I should be able to hear them from here I think
[09:04] <fsphil> then only you can tell atm :)
[09:04] <fsphil> and RocketBoy
[09:05] <Upu> I'll fix the tracker headings

[09:08] <Upu> there you go fixed
[09:09] <natrium42> it's still in Bill Time? :D
[09:10] <Upu> eh ?
[09:10] <Upu> whats bill time ? :)
[09:10] <Upu> <a title="Bill Time">
[09:10] <Upu> Had no idea what that mean so just left it :)
[09:11] <natrium42> :D
[09:11] <natrium42> whenever wb8elk is launching, you have to add a few hours to calculate actual launch time :D
[09:11] <Upu> fixed
[09:11] Nick change: LazyLeopard -> LazyL-M0LEP
[09:14] <LazyL-M0LEP> If these launches are simultaneous(-ish) then I guess we should make sure they're bot being tracked...
[09:15] <m1x10> everybody does SSDV !
[09:16] <LazyL-M0LEP> ;)
[09:16] <number10> Up have they launched or is that old data has yesterdays date on tracker?
[09:16] <number10> Upu*
[09:17] <Darkside> looks like they're on the ground

[09:18] <Upu> number10 they are on the ground at the moment
[09:18] <Upu> I'm tracking on 434.650Mhz
[09:18] <Upu> as 075 is noisy here
[09:18] <Darkside> when it gets higher i might have a listen
[09:18] <number10> ic - looked like xaben1 was at 27K - I was about to bin th AOR
[09:18] <Darkside> though i'll probably bee at an apiary at that point
[09:19] <Upu> refresh number10 those tracks have gone
[09:19] <natrium42> Darkside: you're still in the UK?
[09:19] <Upu> what browser are you using number10 ?
[09:19] <Darkside> yes natrium42
[09:19] <Darkside> i fly back tomorrow night
[09:19] <number10> firefox
[09:19] <Darkside> someone do a launch at 11pm!
[09:19] <Darkside> and i'll track it from the ir
[09:19] <Darkside> air*
[09:19] <natrium42> haha
[09:19] <natrium42> how long is your flight?
[09:20] <Darkside> too fucking long
[09:20] <number10> just refreshed page - tracks mnow clear Upu
[09:21] <Colin-G8TMV> is it two payloads on the same balloon or two seperate balloons?
[09:21] <natrium42> eek, well have a nice flight!
[09:21] <number10> may try to track from car - off to woodbridge today
[09:21] <natrium42> g'night all, good luck with the launch!
[09:22] <number10> night
[09:22] <daveake_> 2 balloons
[09:22] <daveake_> Totex vs Hwoyee
[09:23] <m1x10> ping RocketBoy
[09:23] <Upu> he'll be busy atm I suspect m1x10
[09:24] <LazyL-M0LEP> I'll listen on 434.075 then...
[09:24] <LazyL-M0LEP> Is there any difference other than callsign in the configs?
[09:25] <Upu> don't think so Lazy, different balloons
[09:25] <daveake_> Silly Vodafone dongle ... the dongle cost £20 including 60 days usage, but after that they want to charge £15 *per month*.
[09:25] <LazyL-M0LEP> Upu: That makes sense.
[09:25] <Upu> 800g Hwoyee vs 800g something else
[09:25] <Upu> not sure which is which though
[09:25] <fsphil> m1x10, not everyone :)
[09:26] <Upu> daveake_ I have a Three one that is £4 a month with a fixed IP then 4p a Mb

[09:27] <daveake_> Unfortunately the laptop's sound device doesn't work with dl-fldigi
[09:27] <LazyL-M0LEP> Darkside: So arriving Tuesday morning?
[09:27] <daveake_> So I bought this dongle for my netbook. Obviously I got the wrong one!
[09:27] <Darkside> yup
[09:27] <m1x10> Upu: ok
[09:28] <m1x10> fsphil: who does not?
[09:28] <fsphil> m1x10, ssdv? so far only me and tim are using it :)
[09:28] <daveake_> Upu I tried to unlock it but failed; I'll try again.
[09:29] <m1x10> An Creagan, Omagh, N.Ireland
[09:29] <m1x10> that guy too
[09:29] <Upu> thats fsphil
[09:29] <fsphil> that's me :)
[09:29] <m1x10> lo
[09:29] <m1x10> l
[09:29] <daveake_> lol
[09:29] <fsphil> my launch site is in the middle of nowhere ... but oddly has a cafe there :D
[09:30] <LazyL-M0LEP> Hmmm.... wind here's blowing my antenna about a bit...
[09:30] <m1x10> I very curious if i send the jpeg bytes to afsk modulator routine if they will be all transmitted and i get a picture on my aprs receiver station
[09:30] <Colin-G8TMV> it's quite blowy here too
[09:30] <fsphil> I'm tempted to track from the mountain
[09:30] Nick change: Upu -> Upu_2E0UPU
[09:31] <fsphil> m1x10, you'd need to pack the jpeg into the ax25 packets somehow
[09:31] <m1x10> yes i already do this
[09:31] <fsphil> well then yes, that could work
[09:31] <m1x10> in my telemetry routine
[09:32] <fsphil> it might be more data than amateurs would like though :)
[09:32] <fsphil> they're a grumpy lot ;-)
[09:32] Nick change: fsphil -> fsphil_2I0VIM
[09:32] <fsphil_2I0VIM> look I'm grumpy already
[09:32] <m1x10> well I need to finish that receiver thing. Still didnt buy an antenna. but i guess the magmount will be a first to buy next week
[09:33] <Upu_2E0UPU> I bought one of those spinny wheels for my 817
[09:33] <fsphil_2I0VIM> also if you lost any part of the image, you don't decode the rest unless you do some funky programming
[09:33] <m1x10> are those your callsigns?
[09:33] <fsphil_2I0VIM> yea
[09:33] <fsphil_2I0VIM> Upu_2E0UPU, for the fine tuner knob?
[09:33] Nick change: m1x10 -> m1x10_SW2HYX
[09:33] <Upu_2E0UPU> yeah
[09:33] <m1x10_SW2HYX> :p

[09:33] <fsphil_2I0VIM> yay :)
[09:34] <fsphil_2I0VIM> lol
[09:34] <Colin-G8TMV> lol indeed
[09:34] <m1x10_SW2HYX> i can hear only 144.8
[09:34] <fsphil_2I0VIM> I can hear my tummy...brb
[09:34] <m1x10_SW2HYX> tummy?
[09:34] <LazyL-M0LEP> m1x10_SW2HYX: Yeah, but generally only use a callsign-containing nick during launches.
[09:35] <Upu_2E0UPU> the bit where the food goes after your mouth m1x10_SW2HYX
[09:35] <LazyL-M0LEP> He wants his breakfast! ;)
[09:35] <daveake_> That can be a very strong signal
[09:35] Nick change: m1x10_SW2HYX -> m1x10
[09:36] <m1x10> Upu_2E0UPU: you are tricky! your callsign ends with UPU
[09:36] <Colin-G8TMV> didn't get a choice of calls when I got mine
[09:36] <Upu_2E0UPU> Well we could pick it so I took M6UPU and 2E0UPU
[09:36] <Upu_2E0UPU> Going to try get M0UPU next
[09:36] <Colin-G8TMV> about time - ;)
[09:37] <Upu_2E0UPU> I need more practice in complaining and generally wingeinh about stuff :P
[09:37] <Upu_2E0UPU> spelling
[09:39] <LazyL-M0LEP> Hmmm... G8KHW is switching between 1 and 0, and is on 0 at present. Which one are you listening for, Colin-G8TMV ?
[09:39] <Upu_2E0UPU> best stick on 1
[09:39] <Colin-G8TMV> I've got one on each vfo so I can switch between them - that assumes the data formats are identical of course
[09:40] <Colin-G8TMV> 817 having 2 vfos is handy for that
[09:40] <Colin-G8TMV> can't hear either yet though
[09:41] <LazyL-M0LEP> Good idea. Done likewise...
[09:44] <Colin-G8TMV> Is there a prediction somewhere?
[09:44] <Upu_2E0UPU> how do you switch VFO's ont he 817 ?
[09:44] <Colin-G8TMV> get into the menu with a quich push of "f"
[09:44] <LazyL-M0LEP> It's one of the functions on "A"
[09:44] <Colin-G8TMV> then it's the first set
[09:44] <Colin-G8TMV> button "A"
[09:45] <LazyL-M0LEP> labelled "A/B"
[09:45] <Upu_2E0UPU> oh yeah
[09:45] <Upu_2E0UPU> lol never used VFOb :)
[09:45] <Colin-G8TMV> you should use them equally to avoid wearing one out ;)

[11:08] <fsphil_2I0VIM> that's a fair bit
[11:09] <Colin-G8TMV> yeah, I keep having to re-tune to keep the signal in the passband

[11:11] <Upu_2E0UPU> afc seems to be working
[11:12] <Colin-G8TMV> No - but it drifted up to the top so I need to keep shuffling down
[11:13] <Upu_2E0UPU> has the ascent rate gone down for XABEN1 ?
[11:13] <Colin-G8TMV> yes afc keeps moving the decoder but it doesn't re-tune the rig!
[11:13] <daveake> Getting packets here, but only if I hold the Yagi up high next to the window ...
[11:13] <daveake> ... don't think my arm can hold out for long :-)

[11:16] <fsphil_2I0VIM> Colin-G8TMV, newer version of dl-fldigi have a feature to retune the rig to keep the signal within a set range
[11:17] <Colin-G8TMV> that would be good
[11:17] <LazyL-M0LEP> ...given a CAT connection and working hamlib... ;)
[11:18] <Colin-G8TMV> yeah, I've got that - I'm retuning by mouse clicking on the freq digits
[11:19] <LazyL-M0LEP> Config->dl-client->Enable may have the necessary, then...
[11:19] <fsphil_2I0VIM> if you want to try it can you try the beta version: http://sanslogic.co.uk/files/dl-fldigi-3.21.13-fsphil-github-20110813_setup.exe
[11:19] <Upu_2E0UPU> thats what I have set
[11:19] <Upu_2E0UPU> and it works fine
[11:20] <RocketBoy> upu ta
[11:20] <Upu_2E0UPU> nps thats based on XABEN1 current ascent rate and location

[11:21] <fsphil_2I0VIM> d'oh :) this then ;-) https://github.com/fsphil/dl-fldigi
[11:21] <Upu_2E0UPU> upgrade to Windows :)
[11:21] <GW8RAK> Is Xaben0 on 434.075?
[11:21] <Upu_2E0UPU> somewhere near that
[11:21] Action: fsphil_2I0VIM throws a penguin at Upu_2E0UPU
[11:22] <GW8RAK> Well I've got strong signals, but absolutely no decode. How many bits should there be etc?
[11:22] <Upu_2E0UPU> RV checked ?
[11:23] <GW8RAK> What does RV do? Now checked, but nowt
[11:23] Action: LazyL-M0LEP catches a passing SOTA point along the way...
[11:23] <Upu_2E0UPU> have you picked XABEN0 ? and auto configure or XABEN ?
[11:23] <Upu_2E0UPU> reverses the decoding
[11:23] <GW8RAK> Yes, done that.
[11:23] <fsphil_2I0VIM> you shouldn't need RV for this one if the receiver is in USB mode
[11:23] <Colin-G8TMV> USB on the rig?
[11:23] <GW8RAK> Yes.
[11:23] <Upu_2E0UPU> does it sound like RTTY ?
[11:24] <Upu_2E0UPU> xaben1 is spinning alot I suspect
[11:24] <GW8RAK> Sounds completely normal, no need for the preamp at all, but just rubbish
[11:25] <fsphil_2I0VIM> hmm
[11:25] <fsphil_2I0VIM> no trace here yet
[11:25] <Colin-G8TMV> you have got rtty selected? bottom left box in the status window
[11:25] <GW8RAK> Got a $$Xaben0 there, so not completely wrong.

[11:25] <GW8RAK> Pershaps I'll try the preamp after all
[11:26] <fsphil_2I0VIM> I bet the baud rate isn't exactly 50 :)
[11:27] <GW8RAK> That's better. It seems to be very critical of the shift
[11:27] <Rob_M0DTS> shift is about 370 xaben0
[11:27] <fsphil_2I0VIM> indeed
[11:27] <GW8RAK> Currently on 380 and getting decode
[11:27] <GW8RAK> And now a good one
[11:27] <fsphil_2I0VIM> what dial freq. for xaben0?

[11:29] <Upu_2E0UPU> Decoding fine at 425 so left it alone
[11:29] <Upu_2E0UPU> ok I need to walk the dog so back in a bit
[11:29] <GW8RAK> Don't think I'll have time for the yagi today
[11:29] <fsphil_2I0VIM> I think I see it
[11:30] <fsphil_2I0VIM> oh aye, that's it
[11:30] <Rob_M0DTS> Very good signal, s/n 25dB at times
[11:30] <LazyL-M0LEP> Almost always widen the receive filter bandwidth (which then resets itself whenever anything else changes)...
[11:31] <Rob_M0DTS> yes when it's fair strength wider bandwidth helps with drift
[11:33] <Colin-G8TMV> LazyL-M0LEP: How wide do you set it?

[12:39] <SpeedEvil> I wonder if the dip in ascent rate in the 10-20km range is due to temp
[12:40] <Upu_2E0UPU> Steve said check the decent rate and 10km and divide it by 2 and thats what it should hit the ground with
[12:40] <Upu_2E0UPU> or something like that
[12:40] <LazyL-M0LEP> Lost ben0 at 821 metres
[12:40] <SpeedEvil> I guess 1 should head north soon
[12:41] <Upu_2E0UPU> Xaben0 should be just off the A143
[12:42] <Upu_2E0UPU> Xaben1 looks like it should clear Bury St Edmunds now
[12:43] <SpeedEvil> Very different looking paths - but they may not end up that far apart

[12:43] <RocketBoy> can someone do another land spot for 0 - based on last known pos
[12:43] <RocketBoy> i had to move the car as it was just landing:-(
[12:44] <Upu_2E0UPU> RocketBoy should be off the A143 somewhere between Brandroad and Heath lane
[12:44] <RocketBoy> cheers upu
[12:45] <RocketBoy> just gonna wait here until 1 is down and go to nearest 1st
[12:45] <Laurenceb_> not bad altitude at all :P

[12:45] <Upu_2E0UPU> whats your current location RocketBoy ?
[12:46] <LazyL-M0LEP> Laurenceb: Yep.
[12:46] <SpeedEvil> RocketBoy: Looks like in the middle of a large field with no trees. Ideally.
[12:46] <RocketBoy> 3 miles up the A140
[12:46] <RocketBoy> from the A14
[12:46] <LazyL-M0LEP> ...but there's a rectangular patch of woodland not far away...
[12:47] <Upu_2E0UPU> ok XABEN0 I'll stab a guess at 52.2948, 0.7972
[12:47] <RocketBoy> cool
[12:47] <Upu_2E0UPU> yeah fields with a small patch of woods
[12:48] <Upu_2E0UPU> if the decent rate at 10km is say 18m/s what should I put in the predictor ?
[12:48] <Upu_2E0UPU> 9 ?
[12:48] <RocketBoy> yes
[12:48] <Upu_2E0UPU> k
[12:48] <LazyL-M0LEP> I'll stab at 52.2925 0.7920
[12:49] <SpeedEvil> Density of the atmosphere roughly quadruples every 10km. So rate of descent halves

[14:33] <Upu> it wasn't super slow
[14:34] <LazyL-M0LEP> 5.5-ish?
[14:34] <Upu> didn't note it but ~4.5 - 5.5
[14:34] <jcoxon> what could a 2kg howyee do?
[14:34] <Upu> Under inflated ?
[14:34] <Upu> Probably have to issue a NOTAM to ISS

[14:38] <jcoxon> according to the lighest payload weight picoatlasIV is the lightest
[14:38] <jcoxon> before we added ballast
[14:39] <Upu> just updated UK records
[14:39] <Upu> I think Steve should submit that
[14:40] <Upu> jcoxon you should fit a picoatlas to a 1600g Hwoyee
[14:40] <jcoxon> :-)
[14:40] <Upu> Just to get the world record
[14:41] <jcoxon> its okay
[14:41] <GW8RAK> There'll be a few thinking along those lines
[14:42] <jcoxon> is interesting
[14:42] <jcoxon> the inital thinking would be that to break the records you'd need a light payload + luck
[14:42] <jcoxon> i don't think anyone predicted new balloons
[14:44] <Upu> no
[14:44] <Upu> not even people who should know like Inventek who's high altitude build GPS designed for balloon use tops out at only 2000feet above the current record
[14:44] <Upu> I can see I'm going to have to ask them to increase it
[14:45] <GW8RAK> Get one of Darkside's specials
[14:45] <Upu> whats the GPS ?
[14:46] <GW8RAK> Don't know, but he was talking about it yesterday. His simulator had the GPS at 200km doing 17000mph I think, or something similar
[14:46] <Upu> sounds like someone isn't going to be exporting that from the USA any time soon
[14:47] <jcoxon> ublox are rated to 50km
[14:47] <Upu> I might switch GPS when I redesign Ava's mainboard
[14:47] <GW8RAK> Anyone got a use for xtals on 3180KHz or 3636.5KHz? Just found a bag of them and don't more than a couple each
[14:48] <GW8RAK> QRP rigs on 3636?
[14:50] Action: jcoxon is a bad mood
[14:50] <jcoxon> someone went into the back of my car

[14:50] <jcoxon> on the motorway
[14:50] <Upu> everyone ok ?
[14:51] <jcoxon> yeah
[14:51] <jcoxon> a lorry pulled into the lane and then braked to a stop

[14:51] <Colin-G8TMV> jcoxon: I'm sure that if you were American you'd have a stiff neck by now and be talking to your lawyer
[14:51] <jcoxon> the car behind has a bent bonnet
[14:52] <Upu> I'm sure if you lived in Bradford that would be the case too

[17:57] <danielsaul> It's on an anemometer (wind-speed)
[17:57] <Darkside> it could be some kind of pickup for a rotating magnet?

[20:11] <Darkside> good god, you guys are only getting these now?

[20:11] <Darkside> almost every house in australia has one of those
[20:11] <Darkside> :P

[20:34] <Darkside> i can probably cut the weight down a bit
[20:34] <Darkside> my camera is damn heavy

[20:35] <Darkside> i'm a bit reluctanc to put my SLR in checked luggage

[20:37] <LazyLeopard> Carry the camera by itself?
[20:38] <number10> did you receive over there fsphil?
[20:38] <fsphil> Hwoyee even
[20:38] <fsphil> received but not decoded
[20:38] <fsphil> seemed weaker than normal
[20:39] <fsphil> the one that burst first was stronger though. very odd
[20:39] <number10> what were the specs
[20:40] <fsphil> not sure
[20:40] <number10> did you go to the mountain?
[20:40] <fsphil> nah, too early in the morning :)
[20:40] <number10> :)
[20:41] <fsphil> I found a good spot up there though, line-of-sight to my house. might be able to get wifi
[20:42] <number10> not far from where you live then?
[20:42] <fsphil> 10km-ish
[20:42] <fsphil> should be within range with a good antenna
[20:43] <Darkside> whaaaaaat theres no 'normal' takeaway within heathrow
[20:43] <Darkside> thats weird
[20:43] <fsphil> I'll do some live video next time I'm up there :)
[20:43] <LazyLeopard> Signals seemed reasonable here most of the time. I got BEN0 down to 821 metres and BEN1 down to 708 metres
[20:44] <number10> yes, would be nice to see
[20:44] <fsphil> be cool to launch a balloon on the east coast of the US atm
[20:45] <LazyLeopard> There was a patch up around 25kms where the payloads got spun about a bit, and other occasions when there was fairly deep fading, possibly from wet trees and rain...
[20:45] <number10> dont think you would need the He there

[20:47] <Upu> all payloads from today recovered ?

[20:48] <Upu> anyone decided to wind up ARHAB and post RocketBoy's 4th place ? :)
[20:48] <fsphil> muhaha
[20:48] <fsphil> with such a small balloon too. they'll think it's unpossible
[20:48] <number10> what was payload?
[20:48] <RocketBoy> I'm thinking about it :-)
[20:49] <Upu> Do it Steve pls, if nothing else for the Queen
[20:49] <RocketBoy> for queen and country then
[20:49] <Upu> so what was the payload weight today out of interest ?
[20:49] <fsphil> was there any difference between them RocketBoy? I can't explain the difference in signal strength
[20:50] <LazyLeopard> RocketBoy: You got them both back OK?

[20:51] <RocketBoy> pink pony - sure
[20:51] <fsphil> yay!
[20:51] <Upu> was that the one that came in faster ? Balloon reminants ?
[20:51] <fsphil> oops.. bit of a quick descent? I missed that bit
[20:52] <Darkside> RocketBoy: pinkie pie?
[20:52] <RocketBoy> yeah - the totex almost all came back
[20:52] <LazyLeopard> Yeah, BEN0 came down quite fast...
[20:52] <Upu> came in about 12m/s fsphil
[20:52] <RocketBoy> (must weigh it later)
[20:52] <fsphil> eek
[20:52] <Upu> as opposed to a much more sedate 3.5m/s for the Hwoyee
[20:52] <Upu> or lack of Hwoyee

[20:53] <Lunar_Lander> hi Upu
[20:54] <Upu> evening Lunar_Lander
[20:54] <Lunar_Lander> how are you?
[20:54] <RocketBoy> cant explain the signal strength difference at the mo - might have bent the radials on launch
[20:54] <Upu> very well thanks
[20:54] <Lunar_Lander> hi RocketBoy fsphil NigeyS W0OTM
[20:54] <Lunar_Lander> nice to hear
[20:54] <fsphil> lol
[20:55] <Upu> the difference between the two balloons was way over what I was expecting
[20:55] <fsphil> same ere
[20:55] <Upu> what was the payload weight or have yuo answered this and I've missed it ?
[20:56] <LazyLeopard> BEN1 went up a bit more slowly than BEN0

[20:56] natrium42 (~xela@171.66.88.191) joined #highaltitude.
[20:56] <RocketBoy> yeah - I think that it was mostly due to different drag coefficent
[20:57] <RocketBoy> I think the hwoyee's tend to go up slower
[20:57] Action: SpeedEvil feels much happier towards the current government due to a recent email.
[20:57] <RocketBoy> (for the same fill)
[20:57] <SpeedEvil> 'My associate has helped me to send your first payment of $7,500 USD to you as instructed by the Malaysian Government and Mr. David Cameron the United Kingdom prime minister after the last G20 meeting that was held in Malaysia, making you one of the beneficiaries. '
[20:57] <Upu> can we use any of the data to amend the burst predictor ?
[20:57] <SpeedEvil> That's nice of him.
[20:58] <SpeedEvil> The two balloons were different brands?
[20:58] <RocketBoy> upu - sure thats what I'm intending to do with all the data I have been capturing with flights
[20:58] <SpeedEvil> ah
[20:58] Action: SpeedEvil reads backscroll.
[20:58] <RocketBoy> yeah totex and hwoyee

[20:58] <SpeedEvil> The totex burst at the expected place?
[20:58] <RocketBoy> more or less the same fill - within 50g or so
[20:59] <RocketBoy> identical payloads
[21:00] <RocketBoy> SpeedEvil: just checking that now - but about where I expected
[21:00] <Upu> did you see the altitude the Hwoyee burst at SpeedEvil ?
[21:05] <RocketBoy> the totex was almost exactly to my model - model says burst at 32926 - actual was 33206
[21:05] <RocketBoy> hwoyee was 39500 odd
[21:05] <RocketBoy> :-)
[21:05] <Lunar_Lander> yeah
[21:05] <daveake_> Need a new model for these Hwoyees :)
[21:06] <Lunar_Lander> that means you are near the top of the UK record list once more RocketBoy?
[21:06] <RocketBoy> 2nd !
[21:06] <daveake_> :)
[21:06] <Lunar_Lander> yay!
[21:06] <Lunar_Lander> well done
[21:06] <Lunar_Lander> :)
[21:07] <daveake_> And with a balloon half the size of that Aussies ;)
[21:07] <RocketBoy> (actually 1st if you discount colonialists)
[21:07] <daveake_> lol
[21:07] <Lunar_Lander> xD
[21:08] <m1x10> lol
[21:08] <daveake_> I forsee an increase in sales of Hwoyees very soon
[21:08] <RocketBoy> yeah - i'll need to get even more in
[21:08] <m1x10> RocketBoy: did u get my mail ?
[21:08] <Lunar_Lander> there are no 1500s by Hwoyee, right?
[21:09] <m1x10> Lunar_Lander: just 1000 and 1600
[21:09] <Lunar_Lander> ah
[21:10] <RocketBoy> m1x10 - nope sorry have been balloon chasing all day
[21:10] <SpeedEvil> This payload wasn't very light was it?
[21:10] <RocketBoy> i'll look for it later
[21:10] <RocketBoy> SpeedEvil: yes
[21:10] <m1x10> RocketBoy: sure take your time.
[21:10] <Darkside> how light?
[21:11] <SpeedEvil> ah
[21:11] <daveake_> RocketBoy did you retrieve both of them?
[21:11] <RocketBoy> 200g inc chute line etc
[21:11] <Darkside> RocketBoy: and you got to 39km!
[21:11] <Darkside> WOw
[21:11] <SpeedEvil> 39km - at a fast ascent rate
[21:11] <daveake_> Impressive
[21:11] <natrium42> RocketBoy: any idea where to buy the hwoyee ballons in the US?
[21:11] <m1x10> did it float?
[21:11] <SpeedEvil> m1x10: no
[21:12] <m1x10> so its a myth that hwoyee float?
[21:12] <RocketBoy> natrium42: yes i have - drop me an email and i'll pass on the details
[21:12] <natrium42> ok, cheers!
[21:12] <SpeedEvil> m1x10: IF they are properly filled - like any other latex - it seems that floating may be possible.
[21:12] <RocketBoy> m1x10: no they sometimes float
[21:12] smea (~smealum@85-171-203-85.rev.numericable.fr) left irc: Ping timeout: 240 seconds
[21:12] <RocketBoy> I had it happen to me on the XABEN13 flight
[21:13] <SpeedEvil> Float is made easier the bigger the nonlinearity is before burst in terms of pressure^3/diameter
[21:13] <SpeedEvil> Or something
[21:13] <RocketBoy> i think there is a critical minimum anout of gas needed to burst them
[21:13] <SpeedEvil> Not quite that simple
[21:13] <RocketBoy> but that may vary a bit balloon to balloon
[21:13] <SpeedEvil> It's also payload dependant.
[21:14] <Lunar_Lander> btw
[21:14] <RocketBoy> yeah - probably - a combination of both
[21:14] <SpeedEvil> The nonlinearity before burst acts like it's a net around the balloon, stopping it expanding. This means it has lower volume, and less lift.
[21:14] <Lunar_Lander> how in the world do you pay Hwoyee?
[21:14] <Lunar_Lander> they don't have paypal or so
[21:14] <RocketBoy> you have to do a telegraphic transfer
[21:15] <RocketBoy> personally I'd buy them from me - cos I have all that lot sorted
[21:15] <SpeedEvil> If the magnitude of the lift decrease is more than the free lift - you have a floater.
[21:15] <SpeedEvil> RocketBoy: Sounds sensible. :)
[21:16] <SpeedEvil> The lift decrease is 'constant' only at one altitude though - less gas, less payload, and you can float at a higher altitude.
[21:16] <RocketBoy> SpeedEvil: I need to think about it a bit more - also a differential pressure guage would help understand it
[21:16] <SpeedEvil> Indeed!
[21:16] <SpeedEvil> Differential pressure guage would be awesome.
[21:17] LazyLeopard (~irc-clien@chocky.demon.co.uk) left irc: Quit: Bye
[21:17] <SpeedEvil> What you ideally want is a pressure/diameter graph for a few temperatures.
[21:17] <SpeedEvil> Differential internal pressure
[21:18] smea (~smealum@85-171-203-85.rev.numericable.fr) joined #highaltitude.
[21:18] <SpeedEvil> Though 'just' burst pressure would be good.
[21:18] <RocketBoy> upward facing cam - temp and pressure (via pipe) - all doable
[21:19] <m1x10> the predictor is not working for >35km ?
[21:19] <Lunar_Lander> RocketBoy : at the Lake Constance launch they had a solar powered module in the balloon neck which sent the data down to the main payload by a radio link
[21:20] <SpeedEvil> I don't see the pressing need to avoid a wire.
[21:21] <Lunar_Lander> true
[21:21] <m1x10> oh lol. on 29th is the ideal day for flight. balloon lands 1km away from lauch site!!!
[21:21] <RocketBoy> Lunar_Lander: thats a cool way of doing it

[21:21] <Lunar_Lander> or have that neck payload with an individual SD?
[21:22] <SpeedEvil> Or just stick the payload inside the balloon.
[21:22] <fsphil> I love it when that happens m1x10 :)

[21:38] <Lunar_Lander> RocketBoy : why are the flights of today XABEN 0 and 1 and not 14&15 ?
[21:39] <RocketBoy> well there is a difference between the callsign and the flight number - otherwise we would have to update the tracker for each flight
[21:40] <RocketBoy> actually I used to do that in the early days
[21:40] <RocketBoy> re-prog the payload each flight
[21:41] <RocketBoy> but since there were 2 payloads i needed 2 different calls

[22:36] <RocketBoy> upu - some of the others floated too - darkside's one - and a couple of others were showing a tendancy toward faot just before they burst
[22:37] <Upu> ok
[22:37] <Upu> guess we need more launches to build up a picture

[22:37] smea (~smealum@85-171-203-85.rev.numericable.fr) left irc: Ping timeout: 260 seconds
[22:37] <Upu> I suspect the answer is the flight computer being able to detect a float situation and being able to terminate the ascent
[22:37] <Upu> not using the work pyro any more :/
[22:37] <Upu> word
[22:38] <RocketBoy> a timer would do
[22:38] <RocketBoy> or geofence if you are not worried about duration/chase
[22:39] <Upu> timer has draw backs
[22:39] <Upu> I like the idea of the flight computer being able to detect its going no higher and call it a day
[22:40] <RocketBoy> yep - all doable
[22:40] <RocketBoy> pics from today http://www.flickr.com/photos/16828840@N07/
[22:40] <Darkside> i'd preer to control that from the ground
[22:40] <RocketBoy> say darkside - what do you generate your rtty with?
[22:41] <Upu> would be nice Darkside but adds a whole layer of complexity to it
[22:41] <Darkside> NTX2
[22:41] <Darkside> Upu: yes, but a cutdown device can be made very simple
[22:41] <RocketBoy> yeah - but whats driving it?
[22:41] <Lunar_Lander> but you need the uplink
[22:41] <RocketBoy> DAC
[22:41] <RocketBoy> ?
[22:41] <Darkside> RocketBoy: resistors
[22:41] <Lunar_Lander> if you want to control it
[22:41] <Upu> I've got some code in place
[22:41] <Darkside> Lunar_Lander: yes
[22:41] <Upu> which I'm going to test and see if it makes the correct call
[22:42] <Darkside> NRX2 -> DTMF Decoder 0> Micro
[22:42] <Darkside> and you blast 50W of RF up to it using a yagi
[22:42] smea (~smealum@85-171-203-85.rev.numericable.fr) joined #highaltitude.
[22:42] <Lunar_Lander> yeah
[22:42] <RocketBoy> I have a feeling thats "illegal" in the uk
[22:43] <Darkside> there was a discussion about putting the input to the cutdown on the output of our airborne repeater
[22:43] <Darkside> so if you can hit the repeater, youcan hit the cutdown
[22:43] <Darkside> but then you hav the danger of people accidentally triggering the cutdown
[22:43] <Upu> as you've found out we are very restricted in the UK
[22:43] <Darkside> or not so accidentally
[22:43] <Darkside> Upu: you can do 50W on 2m right?
[22:43] <RocketBoy> cant use a ham radio licence to communicate with something outside the amateure radio service
[22:43] <Upu> with an intermediate license
[22:43] <Darkside> you're transmitting from the ground
[22:44] <Darkside> oh ffs
[22:44] <Darkside> just do it anyway
[22:44] <Upu> lol
[22:44] <Darkside> if its RX on the payload only...
[22:44] <RocketBoy> oh I'm not saying don't do it
[22:44] <Upu> I'll leave it up to the flight computer
[22:45] <Darkside> yeah
[22:45] <RocketBoy> just that I think its technically not allowed
[22:45] <Darkside> i dont like the idea of having a preset limit in the flight computer
[22:45] <Upu> its not rocket science to get it to make the same decisions that we make on the ground
[22:45] <Darkside> i'd like to have the ability to make the decisions during teh flight
[22:45] <russss> wait, is it illegal to have an amateur radio receiver airborne?
[22:45] <Darkside> what i really want is a 2-stage payload system
[22:45] <Upu> My code makes a call based on the rate of ascent
[22:46] <Darkside> where you keep a telemetry transmitter and cutdown/gas-release device at the balloon neck
[22:46] <RocketBoy> russ - don't think so - you planning on going up in a HAB
[22:46] <RocketBoy> ?
[22:46] <Darkside> and you never actually cutdown that telemetry transmitter, only the secondary payload below it
[22:46] <russss> heh
[22:46] <Darkside> so suddenly every flight becomes an opportunity to get an altitude record
[22:47] smea (~smealum@85-171-203-85.rev.numericable.fr) left irc: Ping timeout: 260 seconds
[22:47] <Darkside> as you can drop the secondary payload, release gas until the ascent rate slows, and continue to ascend
[22:47] <russss> well, it's not illegal to (without a license) receive amateur radio
[22:47] <russss> so if your payload happens to be doing that, then it's fine
[22:47] <Darkside> "oh sorry mister ofcom guy i was trying to trigger an IRLP node but i was on the wrong frequency"
[22:48] <Upu> However all my code is mute with out David Miller sorting himself out
[22:48] <fsphil> poor 'ol dave
[22:49] <RocketBoy> well there is reciving it and acting on it
[22:50] <Upu> anyway I best get some sleep night all
[22:50] <Lunar_Lander> gn8 Upu
[22:50] <Darkside> nn
[22:50] <Lunar_Lander> having some accelerometer or so could also be an idea
[22:51] <Lunar_Lander> with that you could also cut the balloon rest away after burst
[22:51] smea (~smealum@85-171-203-85.rev.numericable.fr) joined #highaltitude.
[22:51] <RocketBoy> I don't think there is any issue with it picking up a ham transmission - but if that tx was directed at doing something then the ground station is trying to communicate with somthing outside the amateur radio service
[22:52] <RocketBoy> because the balloon payload is not part of the amateur radio service
[22:53] <RocketBoy> anyways - thats just the way I read it
[22:53] <RocketBoy> your milage may vary
[22:54] <Darkside> i won't have these problems in about 48 hours
[22:54] <Darkside> :P
[22:55] <RocketBoy> so darkkside are you driving the NTX2 with a DAC
[22:55] <RocketBoy> ?
[22:55] <Darkside> no, just the usual resistor network
[22:55] <Darkside> 47K and a 39K
[22:55] <RocketBoy> no shaping?
[22:55] <Darkside> nope
[22:55] <Darkside> i'll be doing some experimentation with the PWM output and some filtering on the MicroNut board
[22:55] <RocketBoy> wow - looked remarkably good
[22:56] <Darkside> i've got the spots there to put in a first order filter to add to the filter already in the NTX2
[22:57] <RocketBoy> yeah - thats too wide for 300baud (or 50)
[22:57] <RocketBoy> more like 4800
[22:57] <Darkside> yeah
[22:57] <RocketBoy> but you did'nt have a filter on the last flight?
[22:57] <Darkside> nope
[22:58] <RocketBoy> cool
[22:58] <RocketBoy> will give it a go myself
[22:58] <Darkside> the aim with the micronut board is to have it able to work APRS too
[22:58] <Darkside> i want a ridiculously small APRS transmitter
