Wispdde is misbehaving, and I'm looking for advice about whether it can be fixed, or whether I should give up with it and try gpredict.

I'm trying to control two SDR radios via orbitron and wisp on Windows 10. The receive radio is run with sdr#, with a cat control client providing bidirectional control from wisp. So wisp/orbitron tracks the doppler, and I can click on the waterfall to select a frequency, which then gets sent back to wisp as the new RX frequency. That by itself seems to be working, although it's kind of slow to respond.

The uplink frequency from wisp gets sent to another radio via cat control. That by itself also works.

The problem is when I use it all together. When I start out wisp, it all works, with the correct uplink sent to the TX radio and the downlink sent to the RX radio. However, after the very first frequency update, wisp puts in an uplink frequency in the same band as the downlink! So for example for RS-44, I start with 145.939 and 435.668, but then it changed to 435.668 in both uplink and downlink.

Has anyone else seen this behavior?
