You don't need to stay parked in the center. Most people who don't use cat control or operate half duplex come up with an offset that is NOT in the center of the passband, but off to the side. Staying parked off to the side is less of a problem for everyone else trying to use the bird...

I’m in a unique situation with 1 cat controllable radio (817) and another that can’t be CAT controlled. Maybe this is non standard. I think it is probably equivalent to using a SDR for receive and a 817 for TX. I don’t think I can leverage the power of tuning around and the software adjusting for me. I will stay parked in the center

And you move around the passband with your VFO, you don't change the .sqf file.

Brian,
Typically the frequencies in the doppler.sqf are center of the passband.

For setting the uplink and downlink frequencies in doppler.sqf, do I set it to one of the many frequencies starting with the AOS and the software will adjust from there?
For example, using ke0pbr frequency cheat sheet for XW-2F, if I wanted to stay approx center, in Doppler.SQF, I would set the file to 435330.0 for uplink LSB and downlink I would set it to 145990.0
If on another pass I wanted to start somewhere else, I could set it to 435340.0 and 145980.0.
In example 1, the software would adjust from 435330.0 to 435350.0 as the satellite passes over me. (AOS to LOS). -- Brian Wilkins KO4AQF _______________________________________________ Sent via [email protected].
