[amsat-bb] Uplink Calibration in SatPC32

I've been learning to operate my station using SatPC32. I'm finding I need
to constantly adjust my uplink calibration in the CAT Tuning menu or I
start to lose myself. On the most recent pass of XW-2A it required
adjustment of about 150 Hz over the duration. This seems like a lot to me -
I know its normal to make fine adjustments at the beginning of a pass but
thought I could then leave it. Is this normal or is something amiss?
If anything I suspect it is related to keps - I update these manually by
going to Satellites and clicking Update Keps. Then selecting the nasa.all
file and Download. Have I missed something?
Station details: Icom IC-9700 transceiver (firmware 1.21), SatPC32 version
12.8d, Windows 10. Crossed yagis on a G-5500 rotator, K3NG based interface.
Thanks in advance and 73,
