[amsat-bb] Problem with SatPC32 Doppler Frequency Control

Dear Folks:
I can't get Doppler correction to work on my SatPC32 program /for most
of the satellites./ Let me be clear that, for SO-50, my Doppler
frequency correction works just fine. That tells me that the hardware,
and some of the software, is set up properly.
Here's the difference that I see. On the top of the SatPC32 screen,
there is a section that shows "Downlink" and "Uplink" frequencies, right
next to the portion where the pushbuttons exist to shift frequencies by
20khz, etc. When I bring up SO-50 on SatPC32, the box below the
"Downlink" and "Uplink" sections is populated with the actual
frequencies, and they change during the course of a pass. On the other
satellites, that box is a complete blank. What do I need to do to get
the data to populate in that box, since I suspect that's what needs to
happen in order for Doppler correction to occur?
Thanks and 73 de Bernie, KF0QS
