[14:20] <jcoxon> hey all
[14:20] <jcoxon> wow 17
[14:21] <jcoxon> i'm back now, all the theatre stuff finished
[14:24] <neontube> hi
[14:24] <neontube> hws it going
[14:25] <jcoxon> not bad
[14:25] <jcoxon> got to bed at 6 this morning after the final show party
[14:26] <neontube> lol fair enough
[14:26] <jcoxon> had a really good time, though was tiring fitting in everything and still going to all my teaching
[14:26] <neontube> have u got a regkey for wxtoimg ?
[14:26] <jcoxon> yup
[14:27] <neontube> how much is it?
[14:28] <jcoxon> 39
[14:29] <neontube> is t worth it
[14:29] <neontube> it seems to go most stuff u might want it to
[14:31] <jcoxon> i'm not too sure
[14:59] <Hiena> http://www.youtube.com/watch?v=rYUgHIEGvMA&feature=related <= Almost related.

[16:55] <RocketBoy> heya jc - hows it going?
[16:56] <Hiena> Groan...

[16:57] <jcoxon> not bad thanks RocketBoy
[16:57] <jcoxon> finally have some time to do some ballooning
[16:57] <jcoxon> how about you?
[16:58] <RocketBoy> yep - still working on things - I have been running a lot of simulations to get cutdown polygon code working
[16:58] <RocketBoy> its all working now
[16:58] <jcoxon> nice
[16:58] <jcoxon> amazing
[16:58] <jcoxon> is it in c?
[16:58] <RocketBoy> yep
[16:59] <RocketBoy> i'll have to put it up on the wiki
[16:59] <jcoxon> hehe,
[16:59] <RocketBoy> I'm just integrating the landing spot predictor
[16:59] <jcoxon> hmmmm everything i do is in python :-p
[17:00] <RocketBoy> so that if the landing spot goes over the polygon the cutdown fires
[17:00] <RocketBoy> python looked quite C line to me
[17:00] <RocketBoy> line = like
[17:01] <RocketBoy> there were some python examples for knl generation I was looking at
[17:01] <jcoxon> its not so good at the maths
[17:01] <jcoxon> its very good for strings
[17:01] <RocketBoy> ah ok
[17:01] <jcoxon> a gps parse would be a lot simpler then in C
[17:01] <jcoxon> for example
[17:01] <RocketBoy> is there scanf in python (there seems to be printf)
[17:02] <jcoxon> as in read from an input stream?
[17:03] <RocketBoy> yep
[17:03] <jcoxon> yes, but i don't think in the same form
[17:04] <RocketBoy> humm
[17:04] <jcoxon> hmmmm apparently it depends, for simple input parsing you can just split the string then convert in to numeric values
[17:05] <jcoxon> for more complicated you can use regular expressions
[17:05] <RocketBoy> cos parsing NMEA with scanf is simple
[17:06] <jcoxon> true
[17:06] <jcoxon> RocketBoy, got my ft-790
[17:07] <RocketBoy> unfortunatly the PIC libary im using doesn't support floating points - so parsing NMEA is a real pain
[17:07] <jcoxon> (might have told you that actually)
[17:07] <jcoxon> urrggghhhh
[17:07] <RocketBoy> nope - you said you won it - does it work OK
[17:07] <jcoxon> that must be annoying, actually the gm862 doesn't do floats ever
[17:08] <jcoxon> RocketBoy, yeah it seems to, i'm about to finish my radio transmitter for firefly so i guess that'll test it
[17:08] <jcoxon> there doesn't seem to be much between 430 and 440mhz
[17:08] <RocketBoy> yep thats par for the course these days
[17:09] <jcoxon> need to get some C batteries
[17:09] <RocketBoy> hang on i'll look for your local ham repeater frequency
[17:13] flowolf (n=flowolf@87.13.187.42) joined #highaltitude.
[17:15] <RocketBoy> GB3PY RB08 433.20 Cambridge (52.21521095,0.037551694)
[17:17] <RocketBoy> 433.20MHz is the output frequency
[17:18] <jcoxon> RocketBoy, i ain't in cambridge though
[17:19] <RocketBoy> nah - just outside
[17:19] <RocketBoy> I'd expect you to be able to hear it
[17:20] <jcoxon> but i'm in london!
[17:20] <RocketBoy> you might have to wait a few mins before it sends its callsign (if its not in use)
[17:20] <RocketBoy> doh
[17:20] <jcoxon> :-)
[17:20] <RocketBoy> must put brain in gear
[17:20] <jcoxon> hehe
[17:20] <jcoxon> well you only ever see me when i am in cam
[17:20] <RocketBoy> well there is loads in london
[17:21] <jcoxon> is there a database?
[17:25] <RocketBoy> GB3LW 433.15 Central London (51.50730861 -0.110911386)
[17:25] <RocketBoy> yep - http://www.ukrepeater.net/repeaterlist2.htm
[17:25] <jcoxon> what setting should that be?
[17:26] <jcoxon> FM?
[17:26] <RocketBoy> yep
[17:26] <RocketBoy> put it on the middle position (simplex?) and twiddle the dial to 433.15
[17:29] <jcoxon> on the readout it ignore the first two digits?
[17:30] <jcoxon> sorry that makes no sense
[17:30] <jcoxon> so it should read 3.15000?
[17:30] <jcoxon> or 3.31500?
[17:31] <RocketBoy> 3.15000
[17:31] <jcoxon> okay
[17:31] <jcoxon> done
[17:31] <RocketBoy> the last MHz digit is displaye before the DP
[17:31] <jcoxon> thats what i remember
[17:32] <RocketBoy> should get somthing within 5 mins or so
[17:32] <jcoxon> okay, i'm listening]
[17:32] <RocketBoy> hissssssssssssssssssssss
[17:34] <RocketBoy> GB3LW is near the south bank
[17:35] <jcoxon> not far from me then
[17:35] <RocketBoy> yep thats what I guessed
[17:46] <jcoxon> what does the outerdial on the volume knob do?
[17:48] <RocketBoy> thats squelch - if you rotate it you should hear the channel hisssssssssssss
[17:49] <RocketBoy> turn it until the his just dissapears
[17:54] <jcoxon> hmmmmm haven't heard anything
[17:55] <RocketBoy> humm
[17:55] <RocketBoy> perhaps its off the air - or you are in a bit of a blackspot
[17:56] <RocketBoy> you could try scanning - you can use the up/down buttons on the microphone to start scanning
[17:57] <RocketBoy> but the squelch needs to be on (i.e. no hiss) 1st
