When FUNcube was first launched, I went out to listen to it on the first
pass that I was home for (orbit #11 I believe). Since I live in an
apartment building, I have to go outside to hear most satellite passes. I
recorded the audio on my normal MP3 voice recorder and to my great
surprise, when I

Hi Phil et All
I can copy and decode the beacon at 30 mw EIRP using the M^2 yagi at very
low SNR ~ 10 db SNR I do not see much fading

I guess I was lucky I dont recall any fading with AO 40

Phil,
That is an interesting question. I have fooled with a simple 1/4 wave
vertical, and observe very bad fading with a period of 10's of seconds
(5 to 10 times longer than individual frames). It seems to my ear that
signals need to be pretty strong in order to decode on AMSAT-UK's
Overall I'll take funcubes telemetry over any AFSK bird It's extremely
simple to receive and in my opinion it's much better than I've ever had
luck on an AFSK bird.

How well is it working? What fraction of the frames are successfully
decoded?
