You save the "Uplink Calibration."

 Thanks to all for the replies. I am in Slovakia, JN88, until 14 December,
so if I can get this sorted I can hopefully give out a few transatlantic
QSOs on AO-7 and RS-44 (from this QTH, I once once held the AO-7 record for
longest QSO, with KC0RA in Iowa). 
Two other quick questions:
1) What is the best source for the latest Doppler.SQF file? The JE9PEL file
linked on the AMSAT UK website
(https://amsat-uk.org/satellites/satpc32-doppler-sqf-file/) is not accurate.
In addition to incorrectly showing RS-44 as NOR, it also is incorrect for
CAS-4A and CAS-4B, and perhaps others.
2) Any tips for fine tuning the frequencies on SatPC32? I was very active on
the sats about 10 years ago, and I recall it being an easy process,
just click the Uplink Calibration buttons in the CAT Control window while
TXing until the voice sounds natural, then save by clicking Change/Store
Data File and then RX/TX Freq. Data. Am I forgetting something? Seems to
require recalibration on every new pass, in was not like that 10 years ago.
