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 haven't done anything with AO-73, but I understand it's transmitting the
FEC format I originally designed for AO-40.
How well is it working? What fraction of the frames are successfully
decoded? How bad is the fading? I designed my format specifically for the
spin fading on AO-40, and if the fading due to the tumbling of a cubesat is
too slow my format won't be able to fix it.
