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

Subject: [amsat-bb] satpc32 doppler ??

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?
