[amsat-bb] [Florida Weak Signal Society] 10 meter satellite PSK

[Robert Bruninga]

Its more interesting that that too.

The reason the 28.118 MHz user uplink has Doppler on it, is because he is
using N0SM's pre-compensated Doppler uplink software.  See
http://aprs.org/psat.html

With this software, you can run your normal PSK31 software for monitoring
the 435.350 MHz FM downlink and run full duplex with N0SM's TX software
for your 28.1xx uplink.  And the uplink is pre-shifted for Doppler so that
everyone seeing the downlink will see your signal constant.

And since it is full duplex, you can be typing with comments to everyone
in the passband at the same time while watching their comments too.  Bob,

NO-84 has a PSK transponder, 10m up and UHF FM down.

calling CQ satellite with drift, but since it says CQ satellite, I guess
it could have been Doppler shift.  Anybody know how this could happen?
