[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? 73 Bob W7LRD
