me too. i do only manual tuning and experienced same problem. i also prefer to manually move my rotor as crossing the end of rotation always has it magically move 360 degrees at the time you either hear the best or just went to work someone.

Tim,
Speak for yourself :-) In the 20+ years I have been a satelliteoperator, I have never gotten computer doppler control to work right on the linear birds. It works great on FM, but I always wind up fighting it on the linear birds. As soon as I tune the other guy in the computer moves me off frequency. It's so much easier to just listen and adjust on the fly.
Maybe there is some secret, but I have yet to be clued in... If someone wants to write a "Dummies Guide" for this I would be willing to be your test subject.

Alan, John and all,
There is no question that computer-controlled Doppler tuning makes working the linear satellites easier. That being said, I am glad that my lack of a computer to dedicate to ham radio forced me to learn and use manual tuning by following the one true rule of always tuning the higher frequency.
These days, I often use SatPC 32 for computer control when I use my two FT-817 QRP rigs for the satellites. But last year, right after Field Day, the CAT plug on my FT-857D stopped working. Because of the choices I've made about my station setup (i.e., a totally portable station that I can set up and operate anywhere at any time), I need to use the 857 as a transmit radio in order to work the DX into Europe and Africa that I have on AO-7 Mode B. And without its higher power on 2 meters, I would not have gotten Hawaii into the log earlier this year on FO-29 from Adrian, AA5UK/KH6. Since the CAT plug died on the 857, I have been manually tuning on every pass during which I use that radio.
