[amsat-bb] SDR for fm sats

Hi Paul,

I occasionally use my SDRPlay RSP1A to just listen to linear and FM sats.
I'm very happy with how it works as I can see any signal on the band and
just click on it to listen.
I haven't attempted to setup doppler correction yet because I don't have a
good transmitting antenna to use in that setup and it is no problem to
adjust the doppler correction manually when listening. Another neat feature
is that the software (SDRUno) can record the entire bandwidth that you are
looking at. For example you could be recording the entire downlink while
the sat is passing and then listen to every QSO from the recording and
decode the telemetry.

I did synchronize the frequency control for when I use the SDR receiver on
HF and that used SDRUno with Omnirig, so I guess any software package that
works with Omnirig will be able to control the frequency. Or if you need
something else, there are other software packages for controlling the SDR,
other than SDRUno.

Best wishes,
Milen KG2C
