[amsat-bb] SatPC32 - need help with configuration of Doppler.SQX file

[Bill Dzurilla]

 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.

 It may also help if you save the file with the correct name as
Doppler.SQF rather than as Doppler.SQX

To save, I clicked on Change/Store Data File and then clicked RX/TX Freq. Data. I thought this was all I needed to do, but on the next pass my TX and RX were again out of sync. On every pass, I need to start over, and each time the uplink frequency is several thousand hertz off. My current line is: RS-44 (DOSAAF-85),435631.85,145970.86,USB,LSB,NOR,0,0,SSB
