[14:34] <rjharrison> the way they split it all up
[14:35] <edmoore> ok - I can try and put it together from this end if you'd like
[14:36] <rjharrison> PM addy
[14:37] <rjharrison> 211.53

[17:19] <russss> heh
[17:20] <edmoore> yep, we won it a couple of years ago, and weren't going to enter 'another' space piccy
[17:20] <edmoore> but apparently they were a bit low on entrants this year and we got asked if we could submit the teds. They did all the paperwork too so really it was about the most passive means of entering a competition possible
[17:21] <SpeedEvil> Get with those people. http://xkcd.com/585/
[17:21] <edmoore> also, we won money rather than an N95, which I think is much better!
[17:21] <SpeedEvil> There is clearly a synergy.

[17:38] <neontube> evening all
[17:44] <neontube> just looking at a load of photos from payloads of loads of different launches
[17:44] <neontube> common problem is spinning payload... how do we stop that?
[17:45] <SpeedEvil> A) Don't
[17:46] <SpeedEvil> Use a fast enough shutter speed - and say 'meh'.
[17:46] <SpeedEvil> It usually doesn't matter if all you want is pretty pictures.
[17:46] <SpeedEvil> B) A massive sail.
[17:46] <edmoore> neontube: hang huge drapes from your payload to damp it

[18:04] <neontube> whats a good irc client to use on linux?
[18:05] <jcoxon> xchat
[18:05] <neontube> not used linux in years, installed it on sunday so i can use some of this tracking software when u next do a launch
[18:06] <neontube> using seamonkey at the mo
[18:06] <neontube> seems to run ok,
[18:06] <jcoxon> oh great - need as many trackers as possible
[18:06] <jcoxon> have you seen the tracking guide
[18:06] <jcoxon> ?
[18:07] <neontube> yer, not sure my current scanner is up for the job though
[18:07] <neontube> on look out for a better one anyway
[18:07] <neontube> current one won't do ssb
[18:07] <jcoxon> oh with out ssb it ain't going to work
[18:07] <jcoxon> unfortunately
[18:08] <neontube> yer i read that
[18:08] <neontube> i thought the transmitter modules were fm though...
[18:08] <jcoxon> indeed they are but we are cheating a little to do what we want
[18:08] <jcoxon> so you need ssb to receive
[18:09] <neontube> i c
[18:09] <neontube> time to crack the lid off it then.. see if it can be modded:P
[18:09] <SpeedEvil> I'm unsure if need is correct - assuming no noise in the capture band.
[18:10] <SpeedEvil> It won't be recievable with fldigi - anyway
[18:10] <SpeedEvil> you'd need your own decoder software that would demodulate the high-pass-filtered RS232 output
[18:10] <jcoxon> SpeedEvil, :-)
[18:10] <jcoxon> ssb is required
[18:12] <neontube> either way, i have an excuse to find a better radio
[18:13] <neontube> well i'm after a couple of different ones
[18:13] <neontube> want something thats a bit better in the upto 30mhz range
[18:14] <neontube> been messing with weatherfax reception
[18:14] <gordonjcp> neontube: general coverage, or amateur bands?
[18:14] <neontube> general
[18:15] Action: gordonjcp saw a really nice FRG-7700 at the Crianlarich rally
[18:15] <neontube> i'm always interested in any sort of data transmission that i can recieve and decode in some way
[18:15] <neontube> done a bit with weather sats and pagers etc
[18:15] <gordonjcp> trunking ;-)
[18:16] <jcoxon> SpeedEvil, have you ever used a biffer board?
[18:16] <jcoxon> i know you advocate them
[18:16] <SpeedEvil> jcoxon: I've looked at them, and am considering buying one.
[18:16] <SpeedEvil> I have not actually used one.
[18:16] <neontube> saw a biffer on a board at the beach
[18:17] <gordonjcp> cute
[18:17] <SpeedEvil> jcoxon: why is SSB required?
[18:17] <SpeedEvil> jcoxon: FM will of course have a low output voltage due to the small swing - and will have a high-pass filtered output that will be comparatively noisy.
[18:18] <SpeedEvil> The performance will be rather poorer with a FM reciever.
[18:18] <jcoxon> SpeedEvil, i understand what you are saying but for people who plan to track our paylods ssb is required
[18:18] <SpeedEvil> (assuming that the signal is strong enough to lock and there are no other signals in the passband)
[18:18] <SpeedEvil> yes - fair enough
[18:18] <SpeedEvil> with the current software anyway.
[18:19] <SpeedEvil> hmm - something to try next time - record a few seconds of audio with FM mode
[18:19] <SpeedEvil> see just how bad it is
[18:21] <jcoxon> yeah
[18:24] <neontube> not that i have a need but... you recon my nieghbours would complain about a set of thease on the house
