I guess this is how it worked in the good old days. \n \nSo, when I faced this situation, I would tune to the calling station then turn OFF my auto-correction and adjust only the uplink slightly to hear myself when transmitting. It worked in most cases. If the calling station puts out a very short CQ, like in FM sats, just TX and ask them to do a longer call. \n \n \nGL es 73! \nUmesh, k6vug \n \n \n On Thursday, May 9, 2019, 1:08:16 AM PDT, Hans BX2ABT via AMSAT-BB <[email protected]> wrote: \n \n How to deal with signals (CW/SSB) where the other party doesn't seem to \ndo doppler correction?
