While using Satpc32 for doppler correction (IC-910H) often I have to "tweek" the calibration using the CAT function. The amount of "tweeking" can vary between satellites and orbits. At times I will simply turn off the auto function and just go manual. Is there a method I can depend more on the computer or am I just getting lazy? 73 Bob W7LRD
I sometimes use the R I T to tweak the receive on each pass. Set it at the beginning of the pass and it usually stays right through the whole thing. I do wish the 910 had a little more range on the RIT.

VO-52 seems to have a different offset per pass, but usually stays constant for the pass, AO7 likewise.
I calibrate when the pass starts by using XIT and usually it stays constant for the whole pass.
That being said, the last 2 VO-52 passes I was on this week, calibration did change during the pass by as much as 400Hz
I've observed this with SATC32 and HRD SAT tracker
