I am sure this has been hashed over in the past but as a novice to the birds I am not sure how to proceed when operating one of the linear transpondesr.
I looked at the latest editions of two ARRL publications: ARRL Operators Manual, edition 9, copyright 1007-2011 ARRL Satellite Handbook, copyright 2010 Both are very clear about how one should allow for Doppler shift on the linear transponders. One clearly says find your spot and then use the downlink VFO to adjust for Doppler shift, don't touch the uplink VFO after the initial setting of the frequency. The other clearly says find your spot and then use the uplink VFO to adjust for Doppler shift, don't touch the downlink VFO after the initial setting of the frequency. Color me confused...
