[07:44] <Darkside> \o
[08:00] <fsphil> morning all
[08:01] <fsphil> all still good for today
[08:01] <Darkside> goddamnit i have no idea about C
[08:02] <Darkside> i.e. how to instantiate a struct

[08:07] <fsphil> yea struct's can be a bit weird
[08:09] <Upu> got some nasty noise on 4434.075
[08:09] <Upu> clicks and pops
[08:09] <fsphil> betcha someone's cutting their grass
[08:09] <Upu> brb off to stab a neighbour
[08:14] <cuddykid> fsphil, best of luck! You launching from your garden?
[08:14] <fsphil> nah, just testing before I leave for the site
[08:15] <cuddykid> oh cool
[08:16] <ingersol> iv'e also got S9 noise on 434.075 from my neighbours oil tank level monitoring device! my own oil tank comes out on 433.970!!!!!
[08:17] <fsphil> euuu
[08:17] <Upu> had this noise last night
[08:23] <fsphil> checking I haven't forgotten anything
[08:24] <fsphil> can someone clear the tracker if they get the chance, get rid of that test data
[08:25] <Upu> was cleared last night
[08:25] <Upu> oh yours
[08:26] <Upu> hopefully someone will wake up
[08:26] <jonsowman> fsphil: cleared
[08:26] <Upu> see :)
[08:26] <fsphil> thanks
[08:26] <fsphil> lol
[08:27] <fsphil> tomorrow's prediction is a bit naff now, glad I'm launching today
[08:27] <Upu> good luck with it fantastic day for it
[08:27] <fsphil> nice here too -- few clouds about, but dry and calm

[08:43] <chembrow> hi upu. any news on the launch yet?
[08:43] <chembrow> I still need to brave it up in the loft to put my antenna up
[08:43] <Upu> still on
[08:43] <Upu> you have time
[08:43] <chembrow> good
[08:43] <chembrow> thanks. need to go up before it gets TOO hots
[08:43] <chembrow> hot
[08:49] <fsphil> still to leave for the site, we'll probably get there about 10:15
[08:49] <fsphil> hopefully still launch at 11:00
[08:50] <fsphil> I'm actually ready in time for once :)

[09:03] <MNSP> Hello all :)
[09:06] <chembrow> hi MNSP
[09:06] <MNSP> Am at work :( Are we on with fsphil?
[09:06] <chembrow> yeah, he left for the site just before you arrived
[09:07] <MNSP> Cool, thanks chembrow
[09:11] <MNSP> Hmm strange though... He's not appearing on spacenear.us
[09:11] <chembrow> might not be there yet. give him a bit
[09:12] <Darkside> oh cool, a launch
[09:12] <Darkside> has anyone here done PSK on an arduino?
[09:12] <Darkside> or does everyone just use the NTX2 modules
[09:13] <jonsowman> ive thought about it a bit darkside
[09:14] <jonsowman> are you talking about phase shifting the carrier?
[09:14] <Darkside> yes, not using a NTX2 tho
[09:14] <Darkside> i'm using a DDS IC, for HF work
[09:14] <jonsowman> no, that would be hard :P
[09:14] <jonsowman> oh right
[09:14] <Darkside> i can easily shift the phase on the DDS
[09:14] <jonsowman> i was wondering if you could DDS a 1kHz sine with an arduino and then phase shift that
[09:14] <Darkside> i'm just figuring out how to implement the PSK varicode
[09:15] <jonsowman> then transmit the resulting waveform using an NTX2
[09:15] <Darkside> that would be sending APSK though
[09:15] <Darkside> i.e. FM modulated PSK
[09:15] <jonsowman> yeah
[09:15] <Darkside> no good for long distances
[09:15] <jonsowman> hmm ok
[09:15] <Darkside> well, not as good
[09:16] <Darkside> anyway, i have the varicode, just need to work out how to use it
[09:16] <Darkside> first step is sorting out a way of parsing the data to be transmitted
[09:16] <jonsowman> yeah
[09:16] <Darkside> and i've got a FIFO working for that
[09:16] <Darkside> the fifo will be useful for RTTY too i guess
[09:17] <Darkside> also all my transmitting functions are interrupt based, driven from an external clock source
[09:17] <Darkside> in my case i'm using the ublox modules timepulse, reprogrammed to output a 100Hz square wave
[09:17] <jonsowman> oh that's neat
[09:19] <Darkside> i'm hoping to get a rough time-of-flight esimate using it
[09:19] <jonsowman> sounds very clever :)
[09:19] <jonsowman> right bbl

[10:55] <fsphil-laptop> lovely signal this time
[10:55] <fsphil-laptop> antenna works ;-)
[10:55] <Upu_2E0UPU> thats because you didn't launch it in a storm this time :)
[10:58] <Rob_M0DTS> Anyone tried 2.4G data transmitters for more data bandwidth?

[10:59] <fsphil-laptop> hmm,, I'm duplicating images
[10:59] <Randomskk> Rob_M0DTS: dubiously legal to fly, and there's significantly more free space path loss at higher frequencies
[10:59] BrainDamage (~BrainDama@dynamic-adsl-94-36-235-37.clienti.tiscali.it) joined #highaltitude.
[10:59] <Randomskk> fspl goes with the square of the frequency
[11:00] <Randomskk> that said, people do fly FPV rc planes and such with 2.4ghz video
[11:00] <Randomskk> you'd need a pretty sensitive receiver.
[11:00] <Rob_M0DTS> true but when it's not far away from launch site the pictures/live video could be interesting!
[11:00] <Randomskk> yea it'd be pretty cool
[11:00] <junderwood_M0JCU> could probably push above 300 baud on 70 cm. Just need the software to decode.
[11:00] <Randomskk> and something a little more sophisticated than rtty perhaps
[11:00] <junderwood_M0JCU> the line of sight seems to be the limiting factor
[11:00] <Randomskk> we have about 1khz bandwidth in the audio pass
[11:01] <Randomskk> though 25khz ish in the channel, just that everyone uses audio receivers :P
[11:01] <Rob_M0DTS> have a 3m dish and good preamp here waitng for anyone to try... ;-)
[11:01] <Randomskk> any guesses on snr?
[11:02] <Rob_M0DTS> i've received the balloon that goes up in holland on ATV before at ~500km
[11:02] <Randomskk> pretty neat
[11:02] <Rob_M0DTS> but thats 1W of power output not 10mW

[11:38] <BrainDamage> have you ever tried to make a web page?
[11:38] <Randomskk> professionally, yes

[11:38] <BrainDamage> except for the rest of the browsers, they behave 99% the same
[11:39] <BrainDamage> with a single exception
[11:39] <Randomskk> have you tried using IE8+?
[11:39] <BrainDamage> no, I stopped
[11:39] <BrainDamage> not interested anymore
[11:39] <Randomskk> I mean, you know, I just use Chrome personally, I don't even run Windows
[11:39] <Randomskk> but I don't think people should be punished for what browser they use
[11:40] <chembrow1> IE6 was an abomination. from IE8 it became much better. still not fully standards compliant, bu
[11:40] <chembrow1> but much better
[11:40] <chembrow1> Randomskk unless they're still using IE6 :P
[11:40] <Darkside> you wouldn't drink 9 year old milk
[11:40] <Randomskk> haha yes, that's a special case :P
[11:40] <cuddykid> should be turning to the west soon according to the predictor, otherwise it may be in trouble with the ocean
[11:40] <Darkside> but then again, i wouldn't drink 2 month old milk either
[11:40] <Randomskk> IE6 is an atrocity
[11:40] <chembrow1> IE6 users need to be beaten with the education stick
[11:41] <Randomskk> though then again a lot of people have no choice - schools and workplaces where IE6 is enforced as the only option

[11:41] <Randomskk> the users are the ones suffering
[11:41] <chembrow1> yeah. we still have to run critical apps which only support IE6 and don't work in anything else. that's what Citrix is for tho
[11:42] <SamSilver> IE6 is big with big biz a lot of them still use it

[12:32] <SpeedEvil> Ah. Local noise?
[12:33] <SamSilver> from the live images it seems to show that the earth is not all that flat but has some-what of a curve in places!! could this be true??
[12:33] <kf5kwe> SpeedEvil, .....? i figured i need some pvc, a downsize fitting, flexible tube, pvc glue and some kind of cap on the end to screw onto the regulator
[12:34] <SpeedEvil> On the low-pressure side, the piping is really non-critical.
[12:34] <Randomskk> SamSilver: nah, of course the earth is flat, it's just a fisheye lens

[13:36] <SpeedEvil> I say again.
[13:36] <SpeedEvil> The predictor is awesome.
[13:36] <SpeedEvil> (also awesome are the pics so far)
[13:37] <junderwood_M0JCU> oops. Wrong turn on the chase car

[13:42] <SpeedEvil> It was transmitting for at least two minutes on the ground
[13:42] <phil__> lost the signal here
[13:42] <phil__> think it landed on a small mountain
[13:43] <junderwood_M0JCU> It's in a small forest to the ENE of you
[13:43] <junderwood_M0JCU> turn right at the T junction in Aghansillagh
[13:44] <jgrahamc> phil__: you'll know you're getting close when you see those two big radio towers along the road.
[13:44] <phil__> we;re passing a wind farm atm
[13:45] <phil__> got a weak signal again
[13:45] <junderwood_M0JCU> about 400 yd beyond the radio towers you need to head towards the forest
[13:45] <MrCraig> think those radio towers are the reason for loss of signal?
[13:46] <jgrahamc> Yeah the closest point on the road is after the radio towers as junderwood_M0JCU says
[13:47] <phil__> found the radio towers

[13:49] <jgrahamc> That looks like a good place to stop

[13:50] <SpeedEvil> I make the trees where it's hit 12m+
[13:50] <SpeedEvil> Which could be fun.
[13:50] <cuddykid> only another ~100m and it would be out in the open

[13:52] <SpeedEvil> It's been transmitting post-landing
[13:52] <cuddykid> doesn't look good terrain, very marshy by the looks on street view
[13:52] <jgrahamc> That's what happened on GAGA-1. Thank goodness I painted it fluorescent yellow and that eroomde has the eyes of a hawk

[13:53] <cuddykid> trees look big too
[13:53] <SpeedEvil> Look at the shadows of the trees.
[13:54] <SpeedEvil> Now, look at the shadow of the buildings around the radio mast
[13:54] <mnsp> I remember it was flourescent colour but didn't know the batteries popped!
[13:56] <jgrahamc> Camera was still running but the transmitter had no power. Happily there was telemetry from very close to the ground.
[14:02] <mnsp> HOpefully recovery shouldn't take too long
[14:02] <MrCraig> idk, it's pretty deep into that forrest
[14:06] <SpeedEvil> And they only have a small chainsaw.
[14:06] <mnsp> bloomin' trees!
[14:07] <MrCraig> A climbing harness might be better placed.
[14:08] <mnsp> On the bright side, at least hadie didn't get wet feet
[14:08] <MrCraig> it did seem to bounce around a fair bit at the tree line, could that be good news, that potentially it was bouncing between trees rather than hooking? *here's hopes it's within reach*
[14:09] <SpeedEvil> Naah,.
[14:09] <SpeedEvil> It's far more likely i's just the GPS signal
[14:09] <SpeedEvil> It will have lost lock on some sats, moving the solution a bit.

[14:22] <mixio> so i dont use batteries all the time
[14:23] <gerry__> Has the An-Cregan payload been recovered?
[14:23] <SpeedEvil> No.
[14:23] <SpeedEvil> They are on their way now - it's 900m from road, in trees
[14:24] <gerry__> the search is still in progress?
[14:24] <SpeedEvil> Probably.
[14:24] <SpeedEvil> They haven't reported back anyway

[14:24] <SpeedEvil> The trees where it landed look ~12m tall - so... But it is still transmitting

[17:36] <fsphil> yea just looking through them properly for the first time
[17:36] <fsphil> they turned out well for such a little camera
[17:37] <fsphil> really chuffed that other people where able to receive the images too

[17:56] <mixio> hi fsphil, did u recover the spacecraft?
[17:57] <fsphil> hi mixio, found it but was 10m up a tree
[17:57] <fsphil> going back for it next week with something to persuade the tree to give it back
[17:58] <mixio> omg throw some rocks to fall
[17:59] <fsphil> think it may be tangled, will get a long pole with something to grab onto the balloon, can pull it down
[18:00] <mixio> mhh
[18:10] <mixio> time to check battery life with AA alkalines
[18:11] <mixio> but i dont have the jpeg cam and radio connected

[20:31] <jgrahamc> Evening all.
[20:32] <jgrahamc> Did hadie:3 get recoverd in the end?
[20:34] <fsphil> not yet jgrahamc, but we know exactly where it is
[20:34] <jgrahamc> Did you manage to see it?
[20:34] <fsphil> going back next weekend with some tree torture tools :)
[20:34] <fsphil> yea, spotted the balloon and parachute
[20:34] <fsphil> no sign of the payload but the coordinates told me it was there too
[20:34] <jgrahamc> Cool. At least you know where it is. That's good.
[20:35] <fsphil> still, 10-15m up :)
[20:35] <jgrahamc> Nice long flight today.
[20:35] <fsphil> it was! a bit longer than I expected
[20:35] <fsphil> was getting a bit worried about how close to the coast we where getting
[20:35] <fsphil> was glad when it turned west
[20:36] <jgrahamc> Well done anyway. Pictures were great.
[20:37] <fsphil> yes that bit worked finally lol
[20:37] <jgrahamc> My 5 element Yagi wasn't really up to getting your signal from 577km away
[20:37] <fsphil> Someone managed 520km, no idea how though
[20:37] <fsphil> where you able to hear it it all?
[20:38] <jgrahamc> OK. Off to do other things. Congrats on a nice flight.
[20:38] <fsphil> thanks!
[20:38] <jgrahamc> I heard CW at one point
[20:38] <fsphil> not sure what that was, the cw module didn't fly this time
[20:39] <jgrahamc> Fair enough.

[21:42] <Dan-K2VOL> oh I see
[21:42] <SpeedEvil> How far around is the trunk?
[21:42] <fsphil> nah I can't cut it down, too many trees around it

[21:45] <Lunar_Lander> cause I didn't
[21:45] <fsphil> they're floating about
[21:45] <Lunar_Lander> ah
[21:45] <Lunar_Lander> that is good
[21:45] <Lunar_Lander> so what is ballooning doing fsphil Dan-K2VOL?
[21:45] <fsphil> Lunar_Lander, http://www.sanslogic.co.uk/ssdv/live.php
[21:45] <SpeedEvil> We're discussing trees again.
[21:45] <SpeedEvil> That should give you a hint.
[21:45] <SpeedEvil> :)
[21:46] <fsphil> lol
[21:46] <Lunar_Lander> damn a failed landing again
[21:46] <SpeedEvil> It's only failed if it's not recovered eventually!
[21:46] <fsphil> well it technically landed fine
[21:46] <Lunar_Lander> yea
[21:46] <fsphil> :)
[21:46] <fsphil> a failed landing is an orbit
[21:47] <Lunar_Lander> xD
[21:47] <Dan-K2VOL> any pics from the flight?

[21:48] <fsphil> the proper pics are stuck up the tree with the camera
[21:48] <fsphil> hopefully get them next weekend
[21:48] <Lunar_Lander> ah so it is still up there
[21:48] <fsphil> yea I didn't have anything that could reach it
[21:48] <Lunar_Lander> damn
[21:48] <fsphil> I've got a 10m pole here, bring that
[21:48] <Lunar_Lander> yea
[21:48] <Lunar_Lander> COOL the SSTV worked
[21:50] <Dan-K2VOL> SSTV or JPEG over RTTY?
[21:50] <fsphil> jpeg-ish over rtty
[21:56] <Lunar_Lander> cool
[21:56] <Lunar_Lander> fsphil I was in the bath yesterday
[21:56] <fsphil> good good
[21:56] <Lunar_Lander> and then I thought: "Oh man, we are soon going to the stratosphere for real!"
[22:00] <fsphil> pretty nifty part of the atmosphere
[22:01] <Lunar_Lander> yeah
[22:02] <Lunar_Lander> I meant that in the way that I recently had no idea of electronics and so on
[22:02] <Lunar_Lander> and you all here helped me with that
[22:02] <Lunar_Lander> that is awesome and I want to thank you all
[22:04] <fsphil> when are you launching?
[22:05] <Lunar_Lander> well I am still preparing
[22:05] <Lunar_Lander> september maybe?
[22:05] <BrainDamage> got the detonator ready?
[22:05] <BrainDamage> airplane tickets?
[22:05] <Lunar_Lander> xD
[22:06] <junderwood> fsphil, nice flight today. Very impressed with the error correction code. It even put packets together when they were wiped out by QRM
[22:07] <fsphil> really? that's a good test!
[22:07] <fsphil> the signal was quite strong here so I never really got a chance to test the error code
[22:08] <junderwood> I kept getting two seconds of static completely swamping the signal
[22:08] <junderwood> The SSTV window said x bits corrected but the picture was fine
[22:08] <fsphil> it can handle 16 bad bytes per packet
[22:09] <junderwood> from about 20km up I only lost a few packets
[22:09] <junderwood> not bad at >500 km
[22:09] <fsphil> so you where able to get complete images?
[22:10] <junderwood> I got a total of 7.5
[22:10] <SpeedEvil> http://fatpita.net/?i=2595 - the truth about space.
[22:10] <fsphil> sweet!
[22:10] <junderwood> I was amazed
[22:10] <fsphil> you got a bigger than usual antenna setup?
[22:11] <junderwood> 9 element yagi at 9m AGL
[22:11] <junderwood> and a good horizon
[22:11] <junderwood> The good video packets seemed to start before the good telemetry packets :)
[22:11] <fsphil> haha, I noticed that in the car

[22:12] <junderwood> Shame about the trees.
[22:12] <junderwood> Probably better than the Irish Sea, though
[22:13] <fsphil> and yorkshire :)
[22:13] <fsphil> at least there I get to go back and try again
[22:13] <junderwood> did that ever turn up?
[22:13] <fsphil> never heard anything about that one
[22:13] <fsphil> probably up a tree too
[22:13] <junderwood> :(
[22:13] <junderwood> not where it landed
[22:14] <junderwood> sunk in a peat bog maybe
[22:14] <fsphil> mm
[22:14] <fsphil> eaten my a sheep
[22:14] <fsphil> by*
[22:14] <junderwood> (rofl)
[22:14] <fsphil> the fields around that forest is pretty boggy too
[22:15] <fsphil> got very wet feet
[22:15] <junderwood> need to write a page for the Wiki: recovery team equipment.
[22:15] <Lunar_Lander> damn
[22:15] <junderwood> Waders
[22:15] <junderwood> Long pole
[22:15] <junderwood> chainsaw
[22:16] <fsphil> should have thought about the long pole, I have one here
[22:16] <junderwood> ditto. It was holding the antenna up
[22:16] <Dutch-Mill> dynamite
[22:16] <junderwood> LCC
[22:16] <fsphil> haha
[22:17] <fsphil> I think if I can get a hold of the balloon, the rest can be dragged out of the branches
[22:17] <fsphil> most of the tree is dead apart from the very top, so it breaks apart pretty easily

[22:20] <fsphil> next weekend is possible, though I'd rather spend that trying to get this one

[22:22] <Lunar_Lander> it's interesting how the predictions change over time
[22:22] <fsphil> quite quickly sometimes too
[22:24] <Lunar_Lander> yeah
[22:26] <junderwood> fsphil, weather forecast says hadie:3 may be washed out of its tree.
[22:26] <fsphil> oh ek
[22:27] <fsphil> rain all week
[22:27] <junderwood> that bog will be fun next weekend
[22:28] <fsphil> guess this camera won't be flying again :)
[22:28] <fsphil> as long as the sd card survives
[22:28] <junderwood> I've only ever once managed to destroy a SD card
[22:29] <junderwood> it was part of a 3600 lb test vehicle which landed without a parachute
[22:30] <junderwood> after a drop from 5000 ft :)
[22:30] <fsphil> I imagine that made a dent
[22:31] <junderwood> not too much of a dent. Solid ground.
[22:31] <junderwood> But the remains of the payload were about 2/3 of their original height
[22:31] <fsphil> I imagine it was a pretty big chute
[22:32] <fsphil> well, should have been a pretty big chute
[22:32] <junderwood> it was. Then it wasn't!
[22:33] <junderwood> You learn far more from the tests that go wrong
[22:34] <fsphil> that's true
[22:36] <fsphil> most of this flight was to test changes made from previous failures :)
[22:38] <junderwood> Most of which worked (very) nicely
[22:38] <fsphil> better than I expected
[22:38] <fsphil> I didn't think too many people would be able to get the image packets
[22:39] <junderwood> I didn't expect to after Hadie:2
[22:39] <junderwood> Maybe it would be an idea to release a small lead weight on a thin cord immediately after landing. Then you have something to pull on if the thing gets stuck in a tree?
[22:41] <fsphil> I'm reasonably sure hadie:2 was flying with no antenna - I suspect it broke off very early
[22:42] <fsphil> weight might work
[22:42] <fsphil> also a sonic locator
[22:42] <fsphil> I walked around the tree for about 10 minutes before I spotted it
