VARA FM and SATPC32 Setting Conflict
I had been having some issues with SATPC32 and my iCOM IC-9700.Β Whenever I was running SATPC32 and RS-44 was active, for some reason if I used the rigβs VFO knob to tune around the passband, it would sometimes caused the Doppler adjustments to stop working.Β All the other satellites were just fine.
I went back to the recommended settings from the SATPC32 documentation and discovered I was twice their recommended baud rate.Β So I lowered things to 57600 baud.Β On my first test, that seemed to fix the problem with RS-44.
However, I also use that radio with WinLink and VARA FM.Β I knew that I was using CAT for PTT, so I needed to drop the baud rate down on that as well.Β Imagine my surprise at finding that 57600 baud didnβt exist as a valid value.
The fix was simple; change from PTT CAT control to COM control.Β I used the same COM port as I had used for CAT control (COM4 in my case), and selected the PTT pin as RTS.Β That worked just fine.
