[06:44] <jcoxon> Darkside, you working on any projects these days?
[06:45] <Darkside> not much ballooning stuff recently
[06:45] <Darkside> lots of uni work
[06:45] <Darkside> and now doing some bitcoin miner ASIC testing
[06:46] <jcoxon> i appreciate all the bit coin stuff
[06:46] <Darkside> im not that into it
[06:46] <jcoxon> but is all the mathematical churning actually useful
[06:46] <Darkside> this job just givs me into a chance to play with some new chips
[06:46] <Darkside> and learn some new PCB design techniques
[06:46] <jcoxon> or are we just wasting cpu/gpu time
[06:46] <jcoxon> and therefore energy
[06:47] <Darkside> i dont have much of an opinion on the matter
[06:48] <jcoxon> fair enough
[06:49] <jcoxon> interesting pico data from yesterday
[06:50] <Darkside> mm
[06:50] <Darkside> and that floater from victoria has a 140g payload
[06:50] <Darkside> 100g hwoyee
[06:51] <jcoxon> 100g hwoyee
[06:51] <jcoxon> wow
[06:51] <Darkside> i did the same a few weeks ago
[06:51] <Darkside> but with a 45g payload
[06:52] <jcoxon> so is ascent rate the key
[06:52] <Darkside> well i would have thought with a 140g payload you'd need to put in too much gas to get the ascent rate
[06:52] <jcoxon> with the pico it seems that its harder to get them to float during the day
[06:53] trn (~trn@adsl-065-007-181-160.sip.bct.bellsouth.net) returned to #highaltitude.
[06:53] <jcoxon> i suspect due to continous heating of the balloon
[06:53] <Darkside> yeah
[06:53] <jcoxon> which keeps it slowly rising
[06:53] <Darkside> i had that problem when i tried a foil
[06:53] <Darkside> i filled inside
[06:53] <arko> ~200W/m^2 yo
[06:53] <Darkside> then took it outside, and i could see the gas volume increasing
[06:53] <arko> thats a good amount of heat

[07:53] <daveake> The flight went straight towards the dish and was then repelled, er, changed direction :)
[07:54] <Martin_G4FUI> I would guess that the dish is out of use being at that elevation, unless it's just a "novelty oversize raingauge"!

[07:56] <Martin_G4FUI> Regrettably I don't have first hand information as I was "otherwise occupied", but I understand it was a cracking day all round
[07:56] <daveake> Horizon and Purley/Kingsley were recovered

[07:59] <Upu> was pretty much flying down LBA runway at 600 meters
[07:59] <Upu> and I can't get a prediciton today
[08:00] <Martin_G4FUI> Couple of weeks ago I was flying down LBA runway at 0 metres heading for sun ... :)
[08:00] <eroomde> you could unleash the 200/300mbar map on wunderground
[08:01] <eroomde> and maybe chew some tobacco as you estimate where it's going to land from the colours and isobars
[08:01] <eroomde> that's how we did it before we wrote the predictor
[08:02] <eroomde> it was good, like asking middle-aged men in a pub about how to drive from one location to another location, you'll get a lot of strong and heated opinions about the best route
[08:02] <eroomde> same with estimate the flight path from the maps
[08:02] <Martin_G4FUI> LBA is challenging enough for airliner jockeys with out having to dodge inflated lumps of latex, apparently ...
[08:03] <eroomde> i bet they hate the flights to ibiza then

[08:11] <Geoff-G8DHE> No sign of it after it closed down but it was quite cold by that time -30
[08:12] <Martin_G4FUI> Is that likely to be a "cold crystal" issue?

[08:21] <eroomde> fz: do each other those devices on VCC have decoupling caps?
[08:21] <eroomde> if noy, add them
[08:21] <eroomde> if not*
[08:22] <daveake> fz No you need all 4 cells in series
[08:22] <eroomde> sorry i briefly went northern-irish
[08:22] <jcoxon> haha
[08:23] <eroomde> fz: the antenna arrangement here might be more cartoony than real but i'd ensure you use a proper aerial, which uses the gnd pins either side of the rf pin on the ntx2 to provide ground for the antenna
[08:23] <fz> eroomde: yup
[08:23] <daveake> fz And you need to look up how to drive an NTX2 (it's in the wiki)
[08:23] <eroomde> jcoxon: recovery is probably the only question-mark for me

[08:25] <jcoxon> Martin_G4FUI, if you want a ntx2 have a chat with upu before ordering
[08:25] <daveake> and the i2c lines from the GPS just go to some regular GPIO pins not the i2c ones (because Pi i2c doesn't (or didn't) work with UBlox)
[08:25] <eroomde> jcoxon: yes that's interesting

[08:59] <fz> eroomde: Sorry for the noob question I'm about to ask but, how do I calculate the uF I need for the decoupling cap?.
[09:00] <fsphil> I'm sure there is a proper answer, but I've always just copied what other circuits have used
[09:00] <eroomde> fz: that's actually a good question and not a n00b one
[09:01] <eroomde> it somewhat depends slightly on the switching frequency, but actually you only have to care about that for really really high freuqnecies. but nor normal chips really all that matters is that they have a low equivalent series resistance
[09:01] <eroomde> as their job is to supply large amounts of current for a very short time
[09:01] <eroomde> so that means a ceramic capacitor
[09:02] <eroomde> and basically everyyone just uses 100n
[09:02] <eroomde> or 0u1 (same thing)
[09:02] <eroomde> i use 100n for everything. don;t really have to think about it unless it's something super-niche
[09:02] <eroomde> also i'd make sure the voltage rating for the capacitor you choose it at least twice your intended operating voltage
[09:03] <eroomde> and get it as physically close as possible to the power input pins of your device

[09:04] <eroomde> yes poss
[09:04] <eroomde> or the following
[09:04] <eroomde> which i also do sometimes
[09:05] <eroomde> is to provide a bigger one near say a whole chip
[09:05] <eroomde> maybe something like 1u
[09:05] <eroomde> i.e. biggish
[09:05] <eroomde> to basically decouple that entire region of pcb that the chip occupies
[09:05] <eroomde> then local decouplers by each power pin pair
[09:06] <eroomde> you have to get the layout right for that to help though, i.e. the power to the decouplers must come from the bigger 1u one
[09:06] <eroomde> and not from somewhere else

[09:07] <fz> gotcha, thanks eroomde.
[09:08] <ibanezmatt13> Would it be a good idea to put a capacitor on the Pi's 5v line to smooth out noise? I'm using the 5v line with a servo motor so switching directions can cause noise which'll make the Pi short out.
[09:08] <eroomde> oh god yes
[09:08] <eroomde> servos are a nightmare
[09:08] <ibanezmatt13> what capacitor will I need?
[09:08] <eroomde> ideally an LC filter

[09:10] <fsphil> morning LeoBodnar
[09:10] <ibanezmatt13> eroomde, would a 100uf ceramic be ok?
[09:10] <Jess--> morning LeoBodnar, I left the rx active all night, nothing heard later on
[09:11] <eroomde> ibanezmatt13: that'll help yes
[09:11] <eroomde> that's a big ceramic tho
[09:11] <LazyLeopard> B-3 seems to have stopped rather suddenly... 14 stations on the last position.
[09:11] <eroomde> electrolytic would help
[09:11] <LeoBodnar> Looks like transmitter cut off suddenly, I was watching it on the waterfall when it suddenly switched off
[09:11] <ibanezmatt13> Are they the cylindrical ones eroomde ?
[09:12] <eroomde> #yes
[09:12] <ibanezmatt13> I'm not sure which I should use, I have many
[09:12] <Jess--> it stopped at 1799 from memory, wouldn't that be where the reset was meant to happen?
[09:12] <eroomde> 100u would be plenty
[09:12] <LeoBodnar> I will modify the tracker and try again XD
[09:12] <eroomde> ideallyrated at least 10V
[09:12] <eroomde> should be printed on the case
[09:12] <ibanezmatt13> I'll have a look
[09:13] <fsphil> how big an inductor?
[09:13] <LazyLeopard> It went through a number of previous resets OK, didn't it?
[09:13] <ibanezmatt13> eroomde, 47uf?
[09:13] <eroomde> inductor size tied to cap
[09:13] <eroomde> cutoff freq of LC filter, in hz, is 1/(2*pi*sqrt(L*C))
[09:14] <eroomde> so you pick and C and L that does the job
[09:14] <eroomde> decision not entirely arbitrary, as inductors have other properties
[09:14] <ibanezmatt13> So all I need to do is connect the positive side to +5v and the negative side to ground, and that's done?
[09:14] <LeoBodnar> Yes, something was not right, I will investigate.
[09:14] <eroomde> like saturation current (make twice as high as nominal current) and DC resistance (which you'd want to keep low for motor stuff)
[09:15] <LeoBodnar> Memory protection address traps, etc.

[09:20] <eroomde> which can be the same as the supply voltage again

[09:44] <LazyLeopard> Apparently B-3 stopped transmitting after line 1799. There's some suspicion that something went terminally wrong with the reset due at line 1800, which is a better scenario than others I can imagine, given its last known location.
[09:44] <Upu> temperature wasn't too low either
[09:45] <mfa298> fsphil: from what he was telling me yesterday they had some good contacts on 70cm, probably just depends on what the conditions are like later
[09:45] <LeoBodnar> B-3 have used below spec power for the PIC, this might have played off eventually.
[09:46] <Herman-PB0AHX> PE2G yes it is a pity that he is out of range but there will be more of challenge or you know
[09:46] <LazyLeopard> Local net reported some good DX "on 70". I didn't think til after the net that he might have meant either 70cms or 70MHz...
[09:46] <fsphil> heh
[09:47] <LazyLeopard> VHF NFD station on local Net...
[09:47] <mfa298> if you're going to fly over heathrow middle of the night is probably the right time to do it (from watching the Airport Live stuff the other week they shutdown the runways for a few hours overnight)
[09:47] <Tommo> waiting for Cheapo flight, i've got two ssb contesters... around the 434.300 mark and one is PA6NL
[09:48] <LazyLeopard> Yeah, last flights tend to leave around midnight-ish, and first ones in are around 0500.

[10:57] <Geoff-G8DHE> Oxygen free ? with or without a green stripe ?
[10:57] <Wouter-[pa3weg]1> stranded also has lower radiation resistance
[10:57] <Martin_G4FUI> Paradoxically, solid is better for crimping on RJ45 connectors than stranded, in my experience, but that's a different ballgame!
[10:57] <Wouter-[pa3weg]1> but I wonder how much that matters on UHF...
[10:57] <Wouter-[pa3weg]1> depends on your RJ45s

[11:18] <kokey> we're into sending email marketing messages so we might as well send some high

[11:19] <kokey> and I don't think I'll be organised enough to get one up when I'm in the UK at the end of the month
[11:19] <GMT> not too sure of the rules and regs in SA, but there are restrictions in the UK
[11:19] <Wouter-[pa3weg]1> greens, hooraay!
[11:19] <Geoff-G8DHE> dl-fldigi does it for you, if its valid then the bar goes green
[11:19] <kokey> yeah I know about the UK situation, was planning a launch there before I moved down the SA
[11:20] <GMT> well, depending upon when and where you are in the UK (when you visit), I'm sure that there will be a weekend launch somewhere, they might be glad of the help
[11:20] <kokey> I've got a tracker using the 434 ISM where I could probably use APRS in south africa
[11:21] <fsphil> WIlldude223: you're not sending a ukhas string. it ignores everything else
[11:23] <G0TDJ_Steve> Can someone confirm Cheapo's freq.? 434.300 yes?
[11:23] <Herman-PB0AHX> yesssssss the first green lines from cheapo
[11:23] <Geoff-G8DHE> 434295050 for 1K25Hz centre
[11:23] <fsphil> cheapo has quite a number of receivers!
[11:24] <fsphil> and only 3.4km up
[11:24] <jcoxon> whats teh Dx field?
[11:24] <G0TDJ_Steve> Blimey! Cracking sig! Thanks Geoff-G8DHE
[11:25] <G0TDJ_Steve> GREEN From Cheapo! Excellent
[11:26] <G0TDJ_Steve> Very solid signal from CHEAPO here in Crayford. Green all the way.
[11:28] <G0TDJ_Steve> Guys, how come the predicted flightpath is so far off? I've never seen that before on Tracker.
[11:28] cuddykid (~acudworth@5.151.1.191) joined #highaltitude.
[11:28] <jcoxon> G0TDJ_Steve, the NOAA servers are down
[11:28] <jcoxon> so we don't have prediction data
[11:29] <G0TDJ_Steve> Oh OK jcoxon
[11:29] <chrisstubbsM6EDF> jcoxon, Dx is the distance from launch location in Km
[11:29] <jcoxon> oh cool
[11:29] <LeoBodnar> Good going chrisstubbsM6EDF !
[11:30] <chrisstubbsM6EDF> Its about 10% out due to the way arduino was handling floats. Only added it last night so didnt have time to mess about tweaking it
[11:30] <GMT> that 'dx' value is an interesting feature
[11:30] <Geoff-G8DHE> Is it Range or Ground track distance ?
[11:30] <chrisstubbsM6EDF> Uses the haversine formula
[11:31] <jcoxon> i guess its ground track
[11:31] <chrisstubbsM6EDF> as the crow flies between launch and current GPS coords
[11:31] <jcoxon> inc altitude Chrisstubbs?
[11:31] <Geoff-G8DHE> yes for a Pico doesn't make much difference
[11:31] <chrisstubbsM6EDF> jcoxon, no
[11:31] <chrisstubbsM6EDF> I guess that could have been applied with a simple bit of pythag
[11:32] <jcoxon> right so now we want it to slow down
[11:32] <jcoxon> ascent rate wise
[11:32] <chrisstubbsM6EDF> Yeah dosent look like its leveling off
[11:33] <fsphil> very slight curve in the ascent graph
[11:33] <jcoxon> give it a chance, when it does it does it quite quickly
[11:33] <chrisstubbsM6EDF> the altitude graph has quite a range on the x axis from testing last night
[11:33] <LeoBodnar> it's hot from the Sun now.
[11:33] <jcoxon> if someone was feeling clever we could delete that point
[11:33] <Geoff-G8DHE> Line of sight now ..
[11:34] <G0TDJ_Steve> chrisstubbsM6EDF: What do you think CHEAPO's max altitude will reach?
[11:34] <chrisstubbsM6EDF> 3500 was the first guesstimate by LeoBodnar
[11:34] <chrisstubbsM6EDF> smashed that now :P
[11:34] <LeoBodnar> Do you know fee lift at launch chrisstubbsM6EDF ?
[11:34] <G0TDJ_Steve> :-)
[11:34] <LeoBodnar> free lol
[11:35] <chrisstubbsM6EDF> LeoBodnar, nope, did it by eye in the garage :(
[11:35] <jcoxon> LeoBodnar, i did some calcs from pico yesterday
[11:35] <LeoBodnar> Right way then!
[11:35] <jcoxon> average ascent rate was 0.9 in the end
[11:35] <jcoxon> for the main part of ascent
[11:35] <Martin_G4FUI> As they say "TLAR" ...
[11:35] <chrisstubbsM6EDF> Its hard to get it neutral, it was sinking, put a puff more in and it was going up at a reasonable rate
[11:35] <Martin_G4FUI> That Looks About Right ...
[11:36] <kokey> has CHEAPO been launched where the Cambridge launches tend to land?
[11:36] <kokey> is this some kind of elaborate recovery? ;-)
[11:36] <Geoff-G8DHE> No sign of it leveling off yet http://360.g8dhe.net/hab_flights/CHEAPO_20130707/
[11:36] <chrisstubbsM6EDF> kokey cambridge launches tend to head towards thetfordish area
[11:37] <chrisstubbsM6EDF> ah darn, GE makes a pretty good graph haha

[11:38] <G0TDJ_Steve> In greenwich! :D
[11:39] <jcoxon> LeoBodnar, we should have a pico theory round table discussion
[11:39] <LeoBodnar> Definitely! I like picos
[11:39] <Darkside> you are also the record holder for lightest payload i think :P
[11:39] <Geoff-G8DHE> LeoBodnar, How are you contrlloing the Tx freq from the GPS ?
[11:40] <jcoxon> i'm not sure that lighter is better in regards to float duration
[11:40] <G0TDJ_Steve> Oh coolio, Thanks zeusbot I'm gonna do my best to go. If only to meet you lot :D
[11:40] <Martin_G4FUI> Forgive a newbie, but is Pico defined as something "impossibly small and light" ?
[11:40] <jcoxon> ascent rate is dropping
[11:40] <chrisstubbsM6EDF> LeoBodnar's picos are almost on the impossible side
[11:40] <Geoff-G8DHE> Pico = Foil balloon
[11:41] <Martin_G4FUI> Ah - thanks!
[11:41] <LeoBodnar> Geoff-G8DHE: sorry I might have misunderstood the question. PIC microcontroller ties GPS and UHF transmitter together.
[11:41] <Martin_G4FUI> Latex has a funny smell anyway ...
[11:41] <chrisstubbsM6EDF> Martin_G4FUI, the one I am flying today: http://bit.ly/16g3NJF http://bit.ly/16g3PkF
[11:41] <Geoff-G8DHE> Yes but how are you controlling the Xtal freq. huffPuff stabliser or ....?
[11:42] kpiman (56b3b7ec@gateway/web/freenode/ip.86.179.183.236) joined #highaltitude.
[11:42] <Geoff-G8DHE> Phase LL or Freq. LL ?
[11:43] <LeoBodnar> No, just correcting PLL divisors knowing actual TCXO offset from referencing it to GPS. Pulling xtal would be too crude and also you need to get PID controller tuned right
[11:43] <Martin_G4FUI> Chrisstubbs, Will you be updating your blog after this flight?
[11:43] <chrisstubbsM6EDF> Martin_G4FUI, of course :)
[11:43] <Martin_G4FUI> Good reading, mate! :)
[11:44] <Geoff-G8DHE> Ah right it was solid last night and it would be nice to see others use the same method!
[11:44] <chrisstubbsM6EDF> LeoBodnar, I forgot to congratulate you last night actually, domino worked very well! How much do you think one of those boards costs you all soldered up?
[11:44] <LeoBodnar> I think it is just a question of time, it's not difficult
[11:45] <Darkside> im certainly interested in the raw Si4460 stuff
[11:45] <Darkside> and how you're doing the disciplining
[11:45] <Geoff-G8DHE> Agreed Domino is excellent! Just need a way to capture the Status text in dl-fldigi
[11:46] <LeoBodnar> Cheers chrisstubbsM6EDF I will let you know the cost after I have calculated the expenses.
[11:46] <LeoBodnar> I have lost count of revisions, versions and updates.
[11:47] cuddykid (~acudworth@5.151.1.191) left irc: Ping timeout: 256 seconds
[11:47] <LeoBodnar> You can use fldigi to see the text at the bottom. It does not overwrite it with status updates like dl-fldigi
[11:48] <jarod> cheapo, nice name :-)
[11:48] <kpiman> What happened to B-3 last night?
[11:48] <Geoff-G8DHE> Ah right, I was hoping it might be saved in the raw text but it doesn't in dl-fldigi
[11:48] <LeoBodnar> transmitter died over Heathrow
[11:49] <kpiman> It was doing so well
[11:49] <Martin_G4FUI> LeoBodnar, do you suspect the cold temperature, or battery life or ...
[11:49] <G0TDJ_Steve> LeoBodnar: Quick question. The lines of text that are received on FLDigi, are they in general GPS format?
[11:49] <LeoBodnar> I think the cold killed it. It was -10C inside the transmitter chip that is usually 10C over ambient PCB temp
[11:49] <Martin_G4FUI> I guess that's one of the tradeoffs when you shed payload weight (lack of insulation)?
[11:50] <LeoBodnar> G0TDJ_Steve: no, they are not NEMA, but derived from GPS output.
[11:50] <LeoBodnar> yes Martin_G4FUI
[11:51] <G0TDJ_Steve> OK Cheers. I do recognise the Lon and Lat in the text. Can you point me to somewhere that explains the rest?
[11:51] <LeoBodnar> I might run processor at higher speed and not let it go to sleep to keep itself warm
[11:51] <Darkside> G0TDJ_Steve: http://ukhas.org.uk/communication:protocol
[11:51] <G0TDJ_Steve> Thanks you Darkside
[11:52] <jcoxon> refresh spacenear.us to get better altitude graph
[11:53] <Geoff-G8DHE> On B-3 it gave the decriptor line as Lat, Lon, Alt, Sat, Vbatt, TempC
[11:53] <Geoff-G8DHE> in the text
[11:53] <Darkside> each payload is slightly different
[11:53] <LeoBodnar> Very gentle decrease in ascent rate
[11:53] <Darkside> payload engineers set up payload profiles in the 'Habitat' backend system, which lets the system decode their telemetry
[11:54] <Darkside> however, the first few elements are usually the same
[11:54] <Darkside> callsign, count, lat, long, alt, sats
[11:54] <Darkside> after that, its usually custom

[11:54] <ibanezmatt13> Anyone know how an NE555 timer could work with a Pi?
[11:55] <Martin_G4FUI> I think it's very apt
[11:55] <LeoBodnar> I'll talk to you later about Si4460 Darkside, I am assembling tonight's payload at the moment
[11:55] <Darkside> kk
[11:55] <Darkside> ibanezmatt13: err
[11:55] <Darkside> why
[11:56] <ibanezmatt13> Well I found one in an old electronics box and I've never used one before
[11:56] <Geoff-G8DHE> Come on everybody has to learn how to design with a 555
[11:56] <ibanezmatt13> Thought I'd see what it can do :)
[11:56] <Darkside> a 555 is generally used as an oscillator
[11:56] <Darkside> analog
[11:56] <Darkside> not really somethign you do wi th ap i
[11:56] <Darkside> with a pi*
[11:56] <LeoBodnar> 555 will make a great hardware watchdog
[11:56] <ibanezmatt13> I saw something about using it to control the timing between turning things on and off. Like a flashing LED
[11:56] Elwell (~elwell@freenode/staff/elwell) left irc: Remote host closed the connection
[11:56] <ibanezmatt13> But the tutorial wasn't very well explained
[11:57] <Geoff-G8DHE> Get the datasheet down for a 555, its a very flexible little beast for doing any timeing sort of function
[11:57] <ibanezmatt13> OK :)
[11:58] <ibanezmatt13> http://www.ti.com/lit/ds/symlink/ne555.pdf
[11:58] <ibanezmatt13> snap
[11:58] <Martin_G4FUI> The temp coefficient of any timing components may well be an issue at extreme altitude (?)
[11:58] <Darkside> yeah
[11:58] <Darkside> resistors will change value
[11:58] dutchtux (~hansh@dhcp-089-098-191-235.chello.nl) joined #highaltitude.
[11:58] <Darkside> caps may too, depending on the substrate
[11:59] <chrisstubbsM6EDF> the xtal on this RFM22B seems much more stable than before
[12:00] <Martin_G4FUI> Something else to chuck into the mix (I hadn't thought of that until now!)
[12:00] <chrisstubbsM6EDF> It uses a SMD HC49 unline the very small ones from habsupplies
[12:00] <Geoff-G8DHE> yes have to say its oly drifiting a little today, maybe temp better ?
[12:00] <Darkside> chrisstubbsM6EDF: thats interesting
[12:00] <Geoff-G8DHE> *only
[12:00] <Darkside> you have a RF22B with a HC49 crystal?!
[12:00] <chrisstubbsM6EDF> cheap ones from alibaba, will take a pic
[12:00] <Darkside> sure its not a RF12?
[12:01] <chrisstubbsM6EDF> silkscreen looks different actually, its probably a fake :
[12:01] <chrisstubbsM6EDF> :P
[12:01] <chrisstubbsM6EDF> seems to be working okay on the balloon though
[12:01] <Darkside> pic already :P
[12:02] <Darkside> but yes, the HC49 will have more thermal mass
[12:02] <Darkside> should drift less
[12:02] <chrisstubbsM6EDF> thats what im thinking
[12:02] <Martin_G4FUI> HABing does remind me of F1 racing, absolutely everything seems to be on the edge of failing all the time!
[12:02] <Darkside> haha
[12:02] <Darkside> not really

[12:03] <Darkside> hrh
[12:03] <Darkside> heh
[12:03] <Darkside> RF22S
[12:03] <Darkside> thats interesting
[12:03] <Darkside> considering the chips on the RF22B's don;t have that on them
[12:03] <Darkside> they have Si43somthing
[12:03] <Darkside> probably a clone
[12:03] <chrisstubbsM6EDF> my one from upu says RF22S too
[12:03] <Darkside> hrm
[12:04] <Darkside> ok maybe not then
[12:04] <Darkside> weird
[12:04] <chrisstubbsM6EDF> unless I mixed it up with another alibaba one
[12:04] <chrisstubbsM6EDF> pretty sure its a habsupplies one

[12:12] <chrisstubbsM6EDF> which is a nice way of doing it, however the rfm22b board takes some of that complexity (and fidly soldering) out so it would be cool if the hc49 crystal was a good compromise

[12:38] <jcoxon> i think we need to resign ourselves to evening launches
[12:38] <jcoxon> to get float
[12:38] <chrisstubbsLTP> only have one 12v socket in the new car
[12:39] <chrisstubbsLTP> yes last nights flight was very successful
[12:39] <Wouter-[pa3weg]1> no 12V radio?
[12:39] <jcoxon> all the floating flights have been so that they start floating around sunset
[12:39] <Wouter-[pa3weg]1> or no splitter, therefore converting back and forth?
[12:39] <LeoBodnar> We need to black out the Sun
[12:39] <jcoxon> eclipse launch
[12:39] <chrisstubbsLTP> lol
[12:40] <Wouter-[pa3weg]1> black out the sun? grabs rifle...everyone shoorts at 3 right?
[12:40] <LeoBodnar> Yeah, float staying in the shadow
[12:40] <Martin_G4FUI> What kind of height do temperature inversions occur during periods of anticlyclonic weather?
[12:40] <Upu> lol
[12:40] <chrisstubbsLTP> mount a parasol above the balloon, doubles up as a chute
[12:40] <LeoBodnar> Extra layer of mylar will do
[12:40] <LeoBodnar> Good at least for something
[12:41] <Geoff-G8DHE_> Fly two balloons one above the other
[12:41] <Geoff-G8DHE_> actually what about cutting loose a Pico from aLatex at say 5.5Kms
[12:42] <chrisstubbsLTP> Hm 1 hour till land at this rate
[12:42] <chrisstubbsLTP> which side of the river will it land, that is the question

[13:03] <Lunar_LanderU> can it be that Win 8 can't use IDE anymore?
[13:03] <Lunar_LanderU> googled and I'm a bit inconclusive
[13:03] <chrisstubbsM6EDF> I will just take 4 laptops and switch between them as the half dead batteries run out

[13:54] <Laurenceb_> wtf
[13:54] <chrisstubbsM6EDF> just cranked the radio volume up, i can still get decodes from chelmsford :O

[13:54] <Laurenceb_> a thermal
[13:54] <Upu> wow
[13:54] <SpeedEvil> Somewhere around dansom park?
[13:54] <GMT> I've got the signal back!
[13:55] <Jess--> it's climbing again GMT
[13:55] <Laurenceb_> it must be in a thermal
[13:55] <Lunar_LanderU> LOL there is a road called Love Lane
[13:55] <Jess--> gained almost 100m
[13:55] <chrisstubbsM6EDF> Silly balloon, stop these games, you have floated past all the easy landing positions!
[13:55] <LeoBodnar> going around, TOGA
[13:55] <chrisstubbsM6EDF> cmon clear these trees

[14:01] <Wouter-[pa3weg]1> hmzzz...trees?
[14:01] <Wouter-[pa3weg]1> not moving on the map
[14:01] <SpeedEvil> May just clear them, dunno.
[14:01] <Geoff-G8DHE> no more updates .....
[14:01] <SpeedEvil> Wouter-[pa3weg]1: There is nobody with signal
[14:01] <SpeedEvil> Did it fade - or cut out instantly?
[14:02] Action: craag_G3KMI_P goes QRT.
[14:02] Nick change: craag_G3KMI_P -> craag
[14:02] <LazyLeopard> Wouter-[pa3weg]1: Yeah, signal went from strong to nothing in about 7 seconds.
[14:03] <chrisstubbsM6EDF> Jess--, your predicion wasnt bad
[14:03] <SpeedEvil> So probably just fading, not impact.
[14:03] <G0TDJ_Steve> chrisstubbsM6EDF: I'm off to find my mate. Keep you're fngers crossed
[14:03] <chrisstubbsM6EDF> would have been bang on if it wasnt for the thermals
[14:03] <eroomde> oh cool we decided to bomb london
[14:03] <chrisstubbsM6EDF> fantastic, thank you very much!
[14:03] <chrisstubbsM6EDF> keep me posted
[14:03] <chrisstubbsM6EDF> will give you a call if we get any updates
[14:03] <LeoBodnar> great flight
[14:04] <G0TDJ_Steve> Roger... gone!
[14:04] <Lunar_LanderU> good flight chrisstubbsM6EDF
[14:04] <SpeedEvil> The trees look to me to not quite be high enough to catch it - if it continued at that slope.
[14:05] <SpeedEvil> Assuming canopy ~= height
[14:05] <chrisstubbsM6EDF> they look about 25m from street view
[14:05] <Geoff-G8DHE> At the last point 69m high the ground is at 34m
[14:05] <SpeedEvil> Oh - I forgot about ground height
[14:05] <SpeedEvil> Ignore the above
[14:05] <Jess--> I can't beleive the prediction was that good apart from the thermals at the end
[14:06] <Geoff-G8DHE> and it had trees so another 10m
[14:06] <chrisstubbsM6EDF> OS map says about 30m
[14:07] <SpeedEvil> I'll agree then - it's in the trees - or at best it _barely_ missed them
[14:07] <SpeedEvil> How long will the batteries last?
[14:07] <LazyLeopard> It's a balloon. It's in the trees. ;)
[14:07] <chrisstubbsM6EDF> last voltage was 4.62

[14:08] <Jess--> A while I should think SpeedEvil, beleive it was meant to float
[14:08] <SpeedEvil> So a really fair amount of time
[14:08] <SpeedEvil> Oh - 1.55V on the cells
[14:08] <SpeedEvil> Bloody ages

[14:18] <WIlldude223> Hi.

[14:19] <chrisstubbsM6EDF> Jess--, ah cool thats not too bad then
[14:19] <chrisstubbsM6EDF> I need to install another 12v socket in the boot at some point
[14:19] <chrisstubbsM6EDF> the splitters are usually so badly made the wire gets hot when you run an inverter from them
[14:19] <WIlldude223> mfa298, daveake: Apologies for being short-tempered and not listening to your advice. I have working RTTY code now and will proceed to try and find a good book on C.
[14:20] <Lunar_LanderU> lol have a look what sorts of ads are on youtube now http://s.gullipics.com/image/i/j/1/ji1rd83-ks10xt-2p5e/WindowsXPYoutubeAdvertisement.png
[14:20] <WIlldude223> How do I get dl-fldigi to check the checksum?
[14:20] <Lunar_LanderU> do they have do do that to sell Windows nowadays?
[14:20] <Lunar_LanderU> xD
[14:20] <chrisstubbsM6EDF> WIlldude223, it will check it automatically
[14:20] <WIlldude223> It doesn't.
[14:20] <chrisstubbsM6EDF> if your sentance is like "$$TEXT*CSUM\n"
[14:21] <Geoff-G8DHE> provided it looks like a standard HAB record
[14:21] <WIlldude223> Ah right.
[14:21] <chrisstubbsM6EDF> I think it needs the double $
[14:21] <daveake> WIlldude223, good stuff. You need to get comfortable with C so you understand how to use it properly otherwise coding will continue to be a big frustration
[14:21] <chrisstubbsM6EDF> and the newline
[14:21] <fsphil> I'm sure I mentione dthis earlier WIlldude223

[14:21] <WIlldude223> fsphil: Sorry, I had to leave in a rush.
[14:21] <Geoff-G8DHE> $$ isn't in the checksum I believe ?
[14:21] <WIlldude223> I probably didn't catch that.
[14:21] <Lunar_LanderU> Geoff-G8DHE: indeed
[14:22] <fsphil> everything between, but not including, the $ and *
[14:22] <Lunar_LanderU> but it needs that to recognize that it is a HAB sentence
[14:22] <chrisstubbsM6EDF> the $$ isnt in the checksum, but dlfldigi needs it to know its a string
[14:22] <daveake> checksum area starts after the last $ and stops before the checksum
[14:22] <daveake> oh yeah before the *
[14:22] <fsphil> it's often easier to construct the strings without those
[14:22] <fsphil> then make one with them, jsut for transmitting
[14:22] <Lunar_LanderU> nice the 2012 GPS from Upu still works
[14:23] <Lunar_LanderU> the one we dunked in the river
[14:23] <Lunar_LanderU> xD
[14:23] <fsphil> the gps I had in the tree for 3 weeks mostly works
[14:23] <fsphil> it'll work for a wihle, then things go weird
[14:24] <Lunar_LanderU> yeah
[14:24] <Geoff-G8DHE> LeoBodnar, Is flight around 1900 again ? Have to work this around the F1 ....
[14:24] <Lunar_LanderU> like the powershot we flew
[14:24] <Lunar_LanderU> it now asks for date and time on a daily basis
[14:24] <fsphil> yea, my Canon didn't survive that flight
[14:24] <fsphil> it switches on, but the screen is destroyed
[14:24] <fsphil> and the sensor just returns a black image all the time
[14:24] <LeoBodnar> Yes, 19:00-ish exactly
[14:24] <Lunar_LanderU> yeah
[14:24] <Geoff-G8DHE> of course what else ;-)
[14:24] <WIlldude223> Well this is peculiar. After adding a callsign, it only txes once.
[14:24] <Lunar_LanderU> I had a stuck aperture in April or so
[14:25] <Lunar_LanderU> then I hit the lens against the desk and it worked again
[14:25] <fsphil> could be that
[14:25] <Lunar_LanderU> :P
[14:25] <eroomde> the gps we put in the north sea for 4 months didn't work
[14:25] <chrisstubbsM6EDF> G0TDJ_Steve, is on the golf course!
[14:25] <fsphil> shocking
[14:25] <Lunar_LanderU> no that caused the pictures to be all white
[14:25] <Geoff-G8DHE> Hope he shouted FORe
[14:25] <Lunar_LanderU> well yeah it stuck open
[14:25] <Lunar_LanderU> if yours is shut then it might well be the case with yours also
[14:26] <WIlldude223> Ah just having the callsign doesn't work.

[14:31] <WIlldude223> Is there a way to make my NTX2 tx on 434.075 instead of '.069?
[14:31] <jdtanner> Why?
[14:32] <WIlldude223> Just cos.
[14:32] <Geoff-G8DHE> not easily is the answer
[14:33] <fsphil> it probably wouldn't stay at 434.075 anyway

[14:37] <fsphil> just different frequency

[14:38] <daveake> Here, 075 is cleaner but it varies
[14:38] <fsphil> yea, opposite here
[14:38] <fsphil> 434.075 is like listening to an old arcade game
[14:38] <daveake> or at least it was cleaner yesterday :p
[14:39] <fsphil> actually a matter of perspective. to anyone else nearby me, 434.650 would be rather noisy :)
[14:39] <daveake> lol
[14:39] <daveake> Also, IIRC 075 stops Upu's car from working, so that's a plus
[14:39] <fsphil> lol
[14:39] <WIlldude223> I hear car keys can be jammed with the ntx2.
[14:40] <fsphil> yea
[14:40] <WIlldude223> But how do I
[14:40] <WIlldude223> :D
[14:40] <Upu> haha
[14:40] <fsphil> I've done it to myself a few times

[14:42] <fsphil> erg, people nearby eating sandwiches -- I can smell onions
[14:43] <WIlldude223> Has anyone ever flown a breadboard tracker before?
[14:43] <fsphil> hopefully not, cause that would be stupid
[14:43] <WIlldude223> :)
[14:43] <WIlldude223> I'm gonna leave my NTX2 on and hope it jams a few car keys.
[14:44] <daveake> breadboard is barely suitable for breadboarding
[14:44] <WIlldude223> Can ntx2s be connected to very large antennas? How do they connect?
[14:45] <Lunar_LanderU> back
[14:45] <Lunar_LanderU> both GPS have lock
[14:45] <daveake> Deliberate interference would also be stupid
[14:45] <eroomde> they can be connected to a radiator or a pet dog

[14:46] <fsphil> I use myself as an antenna sometimes

[15:16] <Lunar_LanderU> yeah more like 600

[15:16] <Lunar_LanderU> the resistor values are OK

[16:19] <G0TDJ_Steve> I was lucky, a guy was walking his dog walking past and passed the balloon over the fence to me
[16:20] <G0TDJ_Steve> I reckon, it was very close to landing, went over the fence and the vortexes from traffic forced it back to the fence.
[16:20] <chrisstubbsM6EDF> Possibly, but it seems like it just made a 90deg turn
[16:20] <chrisstubbsM6EDF> Maybe it landed in the road further up and got blown back down by the oncoming traffic, i dread to think.

[18:27] <Lunar_Lander> ?
[18:27] <LeoBodnar> Upu_M0UPU: new doc number is ee00b5b1db6f3d8067ccaa8e679d5e87
[18:27] <tibs01> i go down there alot :)
[18:27] <Lunar_Lander> Upu_M0UPU, yeah and if it works generally, responding to Navmode and stuff
[18:27] <G0TDJ_Steve> Lunar_Lander: Yes :-) It's here with me
[18:27] <Lunar_Lander> cool!
[18:27] <tibs01> my son lives in dartford
[18:27] <LeoBodnar> is DanielRichman still there?
[18:28] <LazyLeopard> Right on the blue circle up it comes. ;)
[18:28] <Upu_M0UPU> yeah he's sorting it Leo
[18:28] <LeoBodnar> Cheers, you guys are great to be there right when neded!
[18:28] <tibs01> :)
[18:28] <LeoBodnar> needed
[18:29] <G0TDJ_Steve> B4 over a hill to me. It needs to be higher for me to receive
[18:29] <M0CJM_Neil> Lost ot just now
[18:29] <tibs01> crayford hill
[18:29] <M0CJM_Neil> it
[18:29] <tibs01> massive
[18:29] <tibs01> :D
[18:29] <LazyLeopard> Getting about one line in 10 here
[18:29] <tibs01> northend road anyone up there pick it up
[18:30] <Upu_M0UPU> DanielRichman approved the doc LeoBodnar so the auto tracking is now working
[18:30] Action: Upu_M0UPU sits back with a beer
[18:30] Action: Upu_M0UPU raises it to DanielRichman "Team HABHUB"
[18:30] <Lunar_Lander> yay
[18:30] <tibs01> still aint getting nothing in gillingham
[18:30] <LazyLeopard> ...and then it comes clear.
[18:31] <Lunar_Lander> Upu_M0UPU, yes if the ublox gets a fix, accepts commands and stuff
[18:31] <Lunar_Lander> that was the question
[18:31] <Lunar_Lander> :)
[18:31] <LeoBodnar> I'll crack open some spirits later on too! XD
[18:31] <Upu_M0UPU> well if you use NMEA you can use the serial as an interrupt trigger
[18:31] <Upu_M0UPU> Laphroaig 18 sat here :)
[18:32] <M0CJM_Neil> back again :-)
[18:32] <Upu_M0UPU> however I request positions via UBX so I don't use interupts for that

[18:32] <Lunar_Lander> yeah
[18:32] <LeoBodnar> Launch has been delayed by 7 minutes XD
[18:33] <Lunar_Lander> the idea was that we take data while we transmit
[18:33] <LeoBodnar> Due to technical issues
[18:33] Action: tibs01 sits drinking skool larger
[18:33] <Lunar_Lander> and we save those interim lines

[18:34] <G0TDJ_Steve> Nothing heard form B4. Well within the blue footprint now.
[18:35] <Willdude123> Upu_M0UPU: Why does the UBX hardware serial example say to connect TX to TX and RX to rx?
[18:35] <Geoff-G8DHE> Upu_M0UPU, refreshing tracker is not loading B-4 ?
[18:36] <Upu_M0UPU> Geoff-G8DHE do you have a filter on its working for me

[18:37] <M0CJM_Neil> For me with audio centered on 1200 its 434.500.51MHz
[18:37] <Upu_M0UPU> DominoEX16 so starts decoding as before you realise you're not looking at noise
[18:38] <LeoBodnar> Guys, here is DominoEX tip for dl-fldigi: if you want to nudge RX frequency a little bit, use playback <| and |> buttons around center modem frequency (e.g.1200). Clickin with the mouse seems to break currently receiving line.
[18:38] <G0TDJ_Steve> Upu_M0UPU: Generally, what voltage power supply is flown on a HAB? 12v, 5v? Max current?
[18:39] <Upu_M0UPU> G0TDJ_Steve I don't think there is a standard, it depends on the regulator in use
[18:39] <tibs01-2E0SGG> ive just had a flick through 434.300 to 500 nothing yet
[18:39] <Lunar_Lander> btw
[18:39] <Upu_M0UPU> personally I fly single cell AA boosted to 1.8V
[18:39] <G7UXW--Kevin> cool just been tanked by some srever for my data
[18:39] <G7UXW--Kevin> thanked
[18:39] <Lunar_Lander> Upu_M0UPU=daveake=RocketBoy=COOL
[18:39] <Lunar_Lander> xD
[18:39] <G0TDJ_Steve> Upu_M0UPU: OK Had an idea. I expect I'll have to make it useable from 3.3v upto 12v
[18:40] <Upu_M0UPU> well the current draw isn't massive
[18:40] <Upu_M0UPU> <100mA usually
[18:40] <G0TDJ_Steve> OK
[18:40] <Upu_M0UPU> some Linear regulators aren't very "L"DO
[18:40] <Upu_M0UPU> example to run an Arduino you need 6 cells minimum really

[18:41] <Upu_M0UPU> but you can power it for 12 hours from 2 cells with a step up
[18:41] <tibs01-2E0SGG> christ dcs005 b is busy on dstar
[18:41] <G0TDJ_Steve> I was thinking AVR, not a whole Arduino board.
[18:41] <mfa298> ooooh, Is that another DominoEX floater I see (having just returned for NFD)
[18:41] <Lunar_Lander> Anthony, what about the switching that a booster does?
[18:41] <Lunar_Lander> or is that no problem with a good capacitor?
[18:41] <Upu_M0UPU> how do you mean Lunar ?
[18:41] <Upu_M0UPU> I've never had an issue
[18:42] <Upu_M0UPU> the HABDuino board I'm working on has a step up on it
[18:42] <Lunar_Lander> as far as I know these boosters like do rapid switching of a coil or so
[18:42] <Lunar_Lander> yea
[18:42] <LeoBodnar> Not sure about floater but yes G0TDJ_Steve
[18:42] <Lunar_Lander> and you get voltage ripples
[18:42] <LazyLeopard> This one's frequency is drifting a little more than the previous B-*s
[18:42] <Upu_M0UPU> to bypass the onboard Arduino regulator
[18:42] <Lunar_Lander> yea
[18:42] <LeoBodnar> sorry, mfa298
[18:42] <Lunar_Lander> and I wondered if we could power our solid-state counter which needs 9 V from the 3.3V supply and a booster
[18:42] <LeoBodnar> Sorry Mr Gorsky
[18:43] <tibs01-2E0SGG> has the it got a solar panel on board ?
[18:43] <tibs01-2E0SGG> or is it once the batterys flat thats it game over ?
[18:43] <Lunar_Lander> and I think that one needs a good flat voltage on that
[18:43] <LeoBodnar> How much drift LazyLeopard?
[18:43] <mfa298> I'll have to go plug the radio back in.
[18:43] <Lunar_Lander> you know how I mean?
[18:44] Action: tibs01-2E0SGG talks to himself..
[18:44] <Lunar_Lander> tibs01-2E0SGG, normally there are batteries only

[18:54] <tibs01-2E0SGG> how much it cost todo the pcb for it ?
[18:55] <tibs01-2E0SGG> ok steve what other repeater can u get ill tune in can u get any essex ?
[18:55] <Upu_M0UPU> its a long story Leo
[18:55] <tibs01-2E0SGG> gb3ER or gb3DA

[18:55] <tibs01-2E0SGG> lol
[18:55] <LeoBodnar> Why dose it show a detour in location/alt. It is an earlier data but somehow server inserted it in line with the current ones. Does it not sort them by sequential number?

[19:02] <G0TDJ_Steve> £64ish
[19:02] <tibs01-2E0SGG> that it
[19:02] <LeoBodnar> At least some money end up with the community! XD
[19:03] <tibs01-2E0SGG> do you have to get an nov from the rsgb or ofcom to fligh them ?

[19:03] <tibs01-2E0SGG> ahhhhh
[19:03] <G0TDJ_Steve> The Tx's are exempt tibs01-2E0SGG but I think you need CAA clearance

[19:23] <G4MYS-Andy> Shirley Southampton I am the most southerly of the trackers in the city
[19:23] <LeoBodnar> Would investigate why it is drifting. I might expand telemetry data with some geeky stuff since reception seems to be OK for this mode/speed.
[19:24] <fsphil> not a bad idea. do an occasional status dump
[19:24] <fsphil> could even query the gps, get some low level details
[19:25] <fsphil> often when a gps fails we never know what happened
[19:25] <G4MYS-Andy> note there are places called TWAT in Scotland and a little place called Shitlington in Dorset dont have a place name up as people keep nicking it its near Bere Regis

[19:28] <Maxell> do want DomEX flight above Netherlands
[19:28] <fsphil> a float at 5000 would be sad
[19:28] <fsphil> 7000m float would keep it in range
[19:29] <fsphil> though none of them seem all that fast
[19:29] <fsphil> the winds are so slow atm
[19:29] <Wouter-[pa3weg]1> If I would do one, it Would be BPSK1200 with FEC
[19:29] <LeoBodnar> Maxell: more will come! The setup is not optimised for long TX time just yet either. 12-13 hours maybe?
[19:29] <Wouter-[pa3weg]1> (FUNcube modulation)
[19:30] <Maxell> Wouter-[pa3weg]1: does dl-fldigi support that? :P
[19:30] <Laurenceb_> slightly offtopic
[19:30] <Laurenceb_> anyone know of linux video deshaking software?
[19:30] <Maxell> Youtube!
[19:30] <Laurenceb_> ive been trying to use cinelerra
[19:30] <Laurenceb_> but it segfaults without fail
[19:31] <fsphil> Wouter-[pa3weg]1: I give that a go, wasn't able to decode anything
[19:31] <fsphil> though it seems like an interesting mode
[19:32] <LeoBodnar> Unfortunately HABHUB does not have it in the list of modes. Only RTTY, Domino and Hell
[19:32] <fsphil> yea it was never added to fldigi
[19:32] <fsphil> unlikely to be too
[19:32] <jcoxon> LeoBodnar, actually you can use any mode
[19:33] <jcoxon> it just won't autoconfigure it
[19:33] Monty__ (5ac4cee0@gateway/web/freenode/ip.90.196.206.224) joined #highaltitude.
[19:33] <fsphil> any mode in fldigi anyway
[19:33] <fsphil> unless you fancy writing a new modem :)
[19:33] <LeoBodnar> THat's what I wanted to say too
[19:33] <fsphil> hell is a fun mode
[19:33] <fsphil> and by fun, I mean interesting to watch
[19:33] <G0TDJ_Steve> Still nothing heard from B4 here. I live in hope...
[19:33] <fsphil> not so much with the data entry
[19:34] <LeoBodnar> Yes, maybe dual freq tracker?
[19:34] <Maxell> LeoBodnar: Hellscriber? how is it going to parse that?
[19:34] <fsphil> I doubt it offers much over dominoex
[19:34] <fsphil> other than just being neat
[19:35] <g4sgx-iain> Bang, just popped over my horizon, nice sigs and green

[19:35] <LeoBodnar> XD
[19:35] <Maxell> :P
[19:35] <Maxell> Best FEC: human brain
[19:35] <fsphil> it's like the opposite of human computer interface
[19:35] <Maxell> visual cortex
[19:35] <fsphil> computer human interface
[19:35] <SpeedEvil> The human brain sucks at some tasks.
[19:36] <Upu_M0UPU> I'll copy some wind data from 0600 yesterday to try get a prediction
[19:36] <SpeedEvil> Unless you can present it with a task at which it can leverage machinery designed for other stuff.
[19:38] <LeoBodnar> Has anybody studied ascent rate vs free lift dependence for foils? My predictions based on standard drag fail miserably (off by 50%) It is probably the strange shape that makes it difficult
[19:39] <SpeedEvil> Foils?
[19:39] <SpeedEvil> Oh.
[19:39] <SpeedEvil> i read 'aero' before that.
[19:39] <LeoBodnar> It's in invisible ink :)

[19:39] <Wouter-[pa3weg]1> Maybe one day we will put 1200bd BPSK in FLDIGI
[19:40] <Lunar_Lander> hi mclane
[19:40] <Wouter-[pa3weg]1> I´ll propose it to the FUNcube software team
[19:40] <Wouter-[pa3weg]1> so you can track a satellite with FLDIGI ;)
[19:40] <fsphil> that would be cool
[19:41] <Wouter-[pa3weg]1> anyway, it would also be really nice if it could support IQ input, now you always have to put other software in between
[19:41] <Upu_M0UPU> woah live prediction
[19:41] <Maxell> AX.25 packets/APRS is MFSK1200 right?

[19:41] <Wouter-[pa3weg]1> no manchester
[19:42] <Maxell> ah
[19:42] <Upu_M0UPU> no still buggered I copied from an hourly predictor
[19:42] <Upu_M0UPU> from yesterday
[19:42] <Wouter-[pa3weg]1> the trouble is that BPSK is too difficult on the HAB side
[19:42] <LeoBodnar> Haven't seen this for ages Upu_M0UPU :)
[19:42] <Wouter-[pa3weg]1> as in: with the NTXes
[19:42] <fsphil> rtty at 1200 baud has been used
[19:42] <fsphil> FSK
[19:42] <G0TDJ_Steve> I see that Tony
[19:43] <G0TDJ_Steve> No line track though
[19:43] <Wouter-[pa3weg]1> yup, FSK is easy enough
[19:43] Martin_G4FUI (~Martin@mjrigby.demon.co.uk) joined #highaltitude.
[19:43] <Wouter-[pa3weg]1> I think Tim Zaman was doing 1200 on one of his SSDV channels
[19:43] <fsphil> yea
[19:43] <fsphil> for a few larger images
[19:44] <Upu_M0UPU> 1200 RTTY
[19:44] <Wouter-[pa3weg]1> correct
[19:44] <fsphil> it sort of worked, but the main limitation was fldigi's limited bandwidth
[19:44] <LeoBodnar> Few ready made (or not) transmitters would allow phase modulation
[19:45] <LeoBodnar> DDS probably is the way to go there
[19:45] <Chetic> anybody know how to make gnu radio receive and interpret RTTY?
[19:45] <Upu_M0UPU> G4VXE should pop outside and see if he can see it
[19:46] <Chetic> I can't find an example or description anywhere
[19:46] <Wouter-[pa3weg]1> here we go, green on B-4
[19:46] <Upu_M0UPU> Chetic go grab source code for dl-fldigi
[19:46] <Wouter-[pa3weg]1> second one today...
[19:46] <Upu_M0UPU> thats an impressive range Wouter
[19:46] <Upu_M0UPU> you're way out of the horizon
[19:46] <jcoxon> eroomde could prob see it
[19:47] <Chetic> Upu_M0UPU: I'm hoping to find .grc-files rather than reimplementing
[19:47] <Upu_M0UPU> GNU Radio ?
[19:47] <Chetic> yes
[19:47] <Upu_M0UPU> actually LeoBodnar this actually upto date live data
[19:47] <Upu_M0UPU> not familiar with that
[19:49] <LeoBodnar> Servers have deborked?
[19:49] <Wouter-[pa3weg]1> I am familiar with GNURADIO bit to my knowledge it does not have RTTY decoding by default
[19:49] <Upu_M0UPU> still very very slow
[19:49] <Upu_M0UPU> but working
[19:49] <Upu_M0UPU> predictor is working again as well
[19:50] <Maxell> Wouter is cheating, his reciever isn't at the maps position :P
[19:50] <Wouter-[pa3weg]1> I bet some faforable propagation my way + some elevation over ground level + close top the sea
[19:50] <Maxell> yeah
[19:50] <Maxell> it's doable
[19:50] <Chetic> Wouter-[pa3weg]1: thanks that helps
[19:50] <Maxell> DomEX can be decoded even if it's in the noise floor :P
[19:50] <Wouter-[pa3weg]1> it very close to PB0AHXes location
[19:50] <Upu_M0UPU> confirming that
[19:50] <Upu_M0UPU> S/N -17db
[19:51] <Upu_M0UPU> decoding fine
[19:51] <Maxell> lol
[19:52] <Maxell> horay for spreadspecrum
[19:52] <g4sgx-iain> Yep, mine decodes as soon as -17db, not there all the time yet tho.

[20:59] <Relz> G0TDJ_Steve: embedded message?
[20:59] <Upu_M0UPU> well if my test works
[20:59] <LeoBodnar> It beauty is very low S?N decoding. Better than CW

[20:59] <LeoBodnar> *Its
[20:59] <eroomde> yes, i did a calibration and LUT for temp compensation when i did it

[21:31] <Upu_M0UPU> in fact you need Isopropanol to get it off

[21:32] <Upu_M0UPU> the no clean is totally BS
[21:32] <eroomde> S_Mark: do note though that solder has flux builtin
[21:32] M0NSA_A (~HeliosFA@2001:470:6a6f::2000) left irc: Ping timeout: 260 seconds
[21:32] <eroomde> so you often don't need a flux pen to solder down
[21:32] <LeoBodnar> Is it flowing liquid or jelly Upu_M0UPU ?
[21:32] <eroomde> it's useful for reworking though
[21:32] <Upu_M0UPU> like a gel
[21:32] <LeoBodnar> Ordered
[21:32] <Upu_M0UPU> lol
[21:33] <S_Mark> yeah, just the solder I got is quite thin so wanted to get extra incase it burns off before I actually solder
[21:33] <Upu_M0UPU> you need flux
[21:33] <chrisstubbsM6EDF> Ah that sounds like good stuff then
[21:33] <eroomde> well, i wouldn't add too much extra for the first soldering down
[21:33] <chrisstubbsM6EDF> the no-clean i have is like IPA is dries off so quickly
[21:33] <eroomde> if you're having a problem with the builtin flux then you're probably doing the soldering wrong
[21:33] <eroomde> too high a temp or taking too long or something

[21:34] <S_Mark> OK yep
[21:34] <Upu_M0UPU> I tend to put solder on the iron then place iton the comp
[21:34] <eroomde> if the solder leaks little spikes/peaks as you withdraw the iron then that's a sign that you're doing one of those two
[21:34] <Upu_M0UPU> sometimes
[21:34] <eroomde> i dislike doing that too much unless you're quick
[21:34] <eroomde> as the flux sits there boiling off
[21:35] <Upu_M0UPU> regardless of the built in flux additional flux helps in my experiene
[21:35] <Upu_M0UPU> I wouldn't solder without it anyway
[21:35] <LeoBodnar> If anybody still using IPA to clean flux off I urge you to come to your senses and get a liquid flux remover. It's been a long road for me
[21:36] <Upu_M0UPU> hmm
[21:36] <Upu_M0UPU> thats me :)
[21:36] <eroomde> it's also called Flux-Off

[22:03] <Chris_M6CSV> LeoBodnar - Only minor amounts for me. Enough to get bad decodes.
[22:03] <Willdude123> Probably evem harder than rtty code.
[22:04] <LeoBodnar> It's usually OK if it drifts +-100Hz on Domino
[22:04] <Geoff-G8DHE> LeoBodnar, in 45 mins approx the B-4 Tx has drifted 300Hz, compared to last night when it never visibly shifted ?
[22:04] <Willdude123> Upu, is it harder than rtty code?
[22:04] <daveake> yes
[22:04] <daveake> but by then you'll be better
[22:05] <Willdude123> Doubt it,.
[22:05] <LeoBodnar> Something is wrong up there. I have been hacking the code left and right today. Thanks for letting me know. I will include this freq correction in future telemetry to see what it is doing.
[22:06] <Willdude123> Might get an arduino code book instead, there's probably a lot of irrelevant stuff.
[22:06] <LeoBodnar> Geoff-G8DHE: it has probably stabilised by now. It's freezing there! But luckily no wind :)
[22:07] <Geoff-G8DHE> I centerd it at 22:16 and when I just came back up it was just outside the alignment bands in dl-fldig which are jus a bit less than 3ooHz

[22:11] <Geoff-G8DHE> Just interested, mines a dongle but I have another channel being monitored and that hasn't shifted at all its a repeater output!
[22:12] <LeoBodnar> It is the temperature inside the UHF transmitter chip. It is dissipating about 70mW in heat so it's a bit nippy out there. Other chips are colder. Outside temperature is -30C and you have seen the [lack of] insulation.

[23:00] <Geoff-G8DHE> Yes it did cool for a while, but I've not done much coding for the last 5-6 years!
[23:01] <LeoBodnar> You should be able to pick it up again quickly.
[23:02] <Geoff-G8DHE> I suspect so! Its getting enthused into something thats the key!
[23:05] <Herman_PB0AHX> I can not sleep so I thought I'd see if ff b4 still flies and yes he still flies schiterend how that flies
[23:05] <Geoff-G8DHE> The prediction looks good as well if its true!
[23:06] <LeoBodnar> Magic gas!
[23:06] <LeoBodnar> I wonder where B-3 is now?
[23:06] <Herman_PB0AHX> yes it is a pity that I have so much interference on 434
[23:07] <Geoff-G8DHE> it was due to be heading my way but never saw it ;-)
[23:07] <LeoBodnar> It would be cool to have uplink with command to change the TX then we could vote here and change it
[23:07] <LeoBodnar> the TX freq
[23:08] <Geoff-G8DHE> Not so silly all the time we have to use the ISM band!
[23:08] <Herman_PB0AHX> yes that is nice pse do it hihihihihi
[23:08] <Herman_PB0AHX> in the next 1
[23:08] Nick change: GMT -> GMT_afk
[23:10] <LeoBodnar> I guess you can RX somewhere on ham band so it can be blasted up with full ham power allowance by one of the licensed guys here.
[23:10] <LeoBodnar> Is remote control technically illegal?
[23:10] <LeoBodnar> What if it is wrapped in human readable format?
[23:11] <Geoff-G8DHE> well if its in band then we can choose and assign a couple of channels dedicated to HAB work, thenno need to use lots of power either :-)
[23:11] <LeoBodnar> Interesting idea. Patch bugs live?
[23:12] <Geoff-G8DHE> We have remote control of sations built into the licence now so you can have a remote station controlled from elsewhere if you want!
[23:12] <LeoBodnar> Perfect! :)
[23:12] <LeoBodnar> THat would be fun
[23:13] <Geoff-G8DHE> Its the nice thing abou something like 2m - 144-146 (and possibly 147 shortly) we can create our own bandplans and assign as requied
[23:13] <LeoBodnar> Can you use it as a repeater for HAM transmission if TX power is within ISM rules?
[23:14] <LeoBodnar> I think ISM rules do not stipulate what information you transmit as soon as it is 10mW
[23:14] <Geoff-G8DHE> Yes we have lots of repeaters, and also lots of mobile rigs can be switched into a repeater mode - but not normally allowed without reason otherwise there would be too many stations rpeating for no real purpose.
[23:16] <Geoff-G8DHE> All the digital modes allow store and forward as in packet and AX25, its just that radio links are not ideal for TCP/IP
[23:16] <Willdude123> What's HaTTY?
