Hi John, W0JAB
On AO40 you should remember mostly the fading due of spin modulation...... WOW..........WOW.............WOW...... because of rotation of the satellite over the Z axis ! !

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

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.
