A few screenshots of today's flight EDUHAB4 . Seems to be a pattern to my successful reception now. Roughly green at around 8,000 metres and losing it over about 10,000. Once balloon descends I regain contact around 10 again, and keep so until around 4 or 5000. I believe this is due to my Diamond X510N antenna having a low radiation patten. This ties in with the fact that I can only decode the Funcube satellite at a low angle. The simple white stick was better at near overhead Funcube passes, but the Diamond, with it's far better gain, despite the low angle, is more suited to balloon reception up country I think.
