Re: Automatic Doppler Compensation



You didn't mention which satellite you were experiencing this on....  if it 
was FO-29, the downlink doesn't exactly "line up" with the uplink as one 
would expect.  Even with zero doppler shift, it is off by a few kilohertz. 
I have not played with Ham Radio Deluxe much, but suspect that you must 
simply enter a different uplink frequency, shifted by whatever amount you 
found necessary when compensating manually.  You should be able to save it 
once you find the right offset.
