[amsat-bb] Tuning HuskySat-1 telemetry signal

[JoAnne K9JKM]

I'm using an SDRPlay RSP2 and SDRuno software to receive HuskySat here. 
Antenna is a 7 element yagi fixed elevation on a TV rotor for azimuth. 
This contraption is running on manual doppler tracking ... man does that 
move fast ;-)

I seem to see about equal number of decodes between Costas and DP as 
long as I track the tuning accurately enough. Thanks for pointing out 
the different display between the two decoders. I thought I wasn't 
tuning correctly when I first saw the different eye.

This is just me ... but when using Costas it seems I'm closer in tuning 
as long as I can maintain a steady eyeball. For the DP decoder I'm 
appearing to get better decodes when I keep the phasor display as steady 
as possible.
