IC-9700 and SATPC32 linear tuning
Hello folks:
I just upgraded my tired FT-847 for a new IC-9700. FM birds are not a problem but I'm wondering if someone has a good method of finding your signal on the linear birds while using SATPC-32 revision 12.8d. The only way I can vary the TX frequency is under the CAT Tuning menu Upl Calib field. It seems to work but it's a bit clunky and not very quick. If I try to change the transmit frequency on the radio it only gives me a few seconds then reverts back to what is on the main screen of the PC. If I try changing the receive frequency, the transmit frequency changes as well. Probably new radio operator error but I would appreciate any suggestions.
Thanks//Dave WB9YIG
Hi Dave,
On my 9700 I have SATPC32 V+ (VFO Mode On) selected which allows me to tune up and down the band with the radio's VFO knob and SATPC32 freq display follows that and changes accordingly. I also look for my CW signal on the waterfall with CW+ (CW MODE ON) and use the up/down Cal to get synced up then it's a mouse click to CW- to get back to SSB. I'm a newbie but that's what I found so far works for me.

Dave, the "Uplink Calibration" feature has been unchanged for at least 15 years, hi. You are right, the calibration has to be done via the "Upl. Calibr." controls in menu "CAT" (the FT-847 is the only radio that allows uplink calibration additionally by its Sub VFO knob). The program does not cancel the uplink corrections you made "after a few seonds" but continues with the changes until the program is shut down. Of course, it continues with Doppler correction but on the base of the new uplink frequeny. Track an SSB sat - say FO-29 ' . Then correct the uplink frequency in menu CAT until you hear your own signal with the best audio pitch. Then click "Change/Store Data file" and then "Uplink Calibration". That will save the changes in Doppler.SQF (watch the frequency list in menu CAT to see the modification). At the next program start you should immediately hear your signal with the right audio or very close to it. Little remaining deviations (100 - 300) Hz, due to temperature changes etc.) can then be corrected without new storage by the +/- keys of the keyboard (that works only if the main window has the "focus" = dark header line). I tested the IC-9700 during a few passes of FO-29. The audio of my signal remained constant during the whole passes without any corrections.
