[amsat-bb] SatPC32 Ver12.8c and CAT Operating

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.

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.

<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/261186601463>cable 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.
<
