Hi Drew and others, if you want SatPC32 to start off the center of the passband of an SSB/CW satellite do the following: Run the program choose that satellite. Tune the radio to the start frequency you want - say 8 kHz above the center of the passband. Then click menu CAT > Change/Store Data File > RX/TX Freq. Data.
From the next program start the program will start at the new downlink and
uplink frequencies. 73s, Erich, DK1TB

Let me clarify a little. Previous to SatPC32 being the ubiquitous way to operate the transponders, people tended to spread out much more on the linear sats. CW was generally in the lower third to maybe middle, and voice was often spread out over much more of the passband. Now...I love Sat PC32, and I like full Doppler tuning, but just because the program defaults to the middle of the passband doesn't mean everyone should operate within 10 KHz of there.

Spread out and use the VFO! There's no reason to pile up like sardines in the middle. Maybe even (GASP) edit the doppler.sqf file to put you elsewhere in the passband to fine tune things at the start of the pass? Got a schedule, or operating from a rare grid? Let everyone know where to look (i.e. 25 khz up from the middle) and save yourself and others some QRM?

Or just work the transponders (not the FM repeaters) and avoid the lids. That normally means being somewhere other than the exact middle of the passband. I have a few stations that I will absolutely not work until they clean up their operating style. Otherwise, I go out of my way to look for new ops.
If I happen to hear a QSO in progress when I'm checking for my downlink on, say, FO-29, I move further up into the band and continue. I might miss some potential contacts but I'm not in anyone's way.
