I just tested my TS-790E with 12.8c (I hadn't used that radio for a
longer time). With my settings CAT control works flawlessly.
Frequencies and modes are set and updated correctly when I choose a
satellite. When I switch between u/v and u/v sats it is necessary to
click the satellite ident letter twice to activate the changed RX band.
My settings in menu "Radio Setup":
CAT delay 70,
option "Satellite mode" checked (only in the program, not at the radio),
option "RTS +12V" checked. That simulates RTS high and may be necessary
with 12.8c in some cases. So, try wethert that helps. With 12.8c I use
a new component for COM port control witch allows port numbers up to 100
(the old MSComm32.OCX supported only up to 16 port numbers).
I use the Kenwood IF-232c interface connected to the PC via a
USB-to-Serial adapter with FTDI chipset. The cable betwen USB-to-Serial
adapter and interface is a (homemade) straight forward RS-232 cable (no
null modem) with lines ground, RxD, TxD, RTS and CTS wired. Recently
another user (Paul, LB2BG) reported that he got his TS-790 working with
SatPC32. I will forward his mail to you. Perhapas he can tell you how he
has connected the radio to the PC.
With the TS-790 the the downlink must appear in the right window (SUB).
