Fred,
I will tell you that I get at times some similar types of conditions with SatPC32 12.8C and my FT847. The radio will flip USB modes on the main band and sometimes the transmit sub band while I am tuning the passband. I have assumed that this might be a feature of tuning too fast and the data stream getting confused. I can see this happening whether I set the radio/Com port to 9600 or 57.6 but think it is a bit more prone at 57.6 Kb/s.
Any body have suggestions?

Hi folks,
I am trying to get back into the satellites and have a Kenwood TS-790A which I am using with SatPC32 Ver12.8c. I am using THIS http://www.ebay.com/itm/261186601463cable for CAT control (after research it seemed to be one of the best and reliable cables for the purpose).
During the operation of the radio during a pass using AO-85 I have found that SatPC32 keeps switching the mode from FM to USB. It stopped doing that when I disconnected the USB to accessory plug but of course it stopped correcting for doppler as well. When I investigated this I noticed that the
AO-85 line in the DOPPLER.SQF file seemed to be missing a comma, see below:
; For Hints look at the end of this file.
; Do not remove or modify these first
; 3 lines of the file, starting with ';'!
AO-85,145980,435180FM,FM,Nor,0,0,Voice U/V
AO-10,145900.0,435100.0,USB,LSB,REV,0,0
AO-73,145960,435140,USB,LSB,REV,0,0,Voice U/V AO-73,145935.0,,USB,,,,TLM ........
I corrected that and saved it and restarted the computer and the program.
It continues to do it and I can't figure out why. So, on this radio there is a "Main" channel which is on 70 cm which I transmit on and there is a "Sub" channel which is on 2 meters which I receive on. The "Main" channel tracks the doppler correctly and remains on FM but the "Sub" tracks the frequency correctly but keeps switching to USB. Does anyone have any thoughts on how to correct this or am I doing something wrong?
Thanks so much for your time.

I saw that with a USB serial port which wasn't able to keep up with the data. I switched to a "real" PCI serial port, and that cleared it up. There is also a CAT delay parameter in SatPC32 which is worth exploring.

I have an ongoing issue with my Arduino rotor controller (K3NG software) in that SatPC32 appears to send it weird az/el info, sending the rotors to their full stops. It's kind of a pain in the backside. Adjusting the frequency of antenna aiming changes has some effect -- similar, perhaps, to the CAT delay.
Yes Alan, it definitely is an issue at the 57K baud rate but still is at times at 9600. And you would thank that a USB to serial adapter would work happily at 9600. The only way to be portable for me is with a USB only laptop. I do currently have the cat delay set to 30 but I can try with some different numbers.
