Reid,
You could fake up a geostationary satellite. Theoretically the Doppler shift would be zero. Practically, very close to zero, depending on how good your tweaking is.
If you placed it below your horizon, say on the other side of the earth, the antennas would point at the desired parking position between passes. The rig would remain in satellite mode however, but maybe that is enough?

It's a thought. I don't mind the sat mode as long as the idle frequencies and modes are the ones (2 meter and 70cm) are the ones I want to continue to monitor when not tracking an active satellite. I believe SATpc does allow prioritizing the satellites in the SQF files, so that could work making the fake geo bird a lower priority. WISP32 use to allow you to do this and use a priority number. However, using SATpc to control the rig now.
Still use WISP32 for a fast check on in range satellites. However, it goes flaky on Windows 10 64-bit sometimes and I have to renter at least one satellite and the rest show back up. It appears to be how the new registry is used by WISP32.
Will experiment some and see what I come up with.
