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
Did you enter the frequencies in your doppler.sqf file? Please read the manual. It explains exactly what you need to do.
