Hi Tom, the program updates both radio frequencies for Doppler correction as soon as the Doppler shift of the higher band changed by a certain amount of Hz (interval). You can set the interval in menu "CAT", separatedly for FM and SSB. Set the FM interval to - say - 100 Hz and the SSB interval to 50. With SO-50 the program will then update both radio frequencies when the Doppler shift of the UHF downlink changed by 100 Hz or more. 73s, Erich, DK1TB

Thanks to the response from the group. The V+ setting worked fine. I knew I was missing something.

The CAT control via the Virtual Serial Port Emulation software is a bit finicky and sometimes may take 5 or 10 seconds to update SatPC32 as Doppler changes, Then it will seem to catch up and be pretty current. Oh well. I think though it will work for what I need.

Thanks to all.
