Re: [amsat-bb] Doppler correction?

["Robert Turlington" <rob_g8ate@xxxxxxxxxxx>]

Hi John
All I can say is make sure the PC clock is within one second and make sure 
the AFC window in Hamscope is set to 100Hz (this is the maximum). Also you 
can control the Rx audio frequency in hamscope manualy using the up/down 
keys just to fine tune things now and again if the Rx signal goes out of the 
AFC window.
