[amsat-bb] PSAT PSK31 transponder

[David W0DHB]

This last pass of PSAT I was able to successfully decode myself and others
(KI4ENY, K0RJV) using DM780 and MixW.

 

Couple of observations:

1)      MixW is the only PSK31 program I could find which can do full
duplex, 2 running copies of DM780 and fldigi work also.

2)      Using SATPC32 Doppler Shifting Uplnk and Downlink, set to 10 Hz
interval with "times 10" selected kept the downlink signals fairly stable
frequency wise.

3)      Probably due to TLE's, Uplink signal downlinks about 400 Hz High.

 

A recording of the pass can be found here:
