you didn't purchase the wrong radio, hi.
SatPC32 supports CAT control of the IC-821H. A friend of mine and I myself
used the IC-821H for several years. I have just tested CAT control of this
radio once again under Windows 7, 32-bit, and Vista, 64-bit. CAT control
works flawlessly. With SSB-satellites I could tune the RX frequency with the
radio's VFO knob and the program tuned the TX Vfo to the right uplink
frequency (transparent tuning).
My settings in menu "Radio Setup":
CAT baudrate: 19200,
Icom address: $4C (both values, default address of the IC-821H).
COM port number of the USB-to-Serial adapter,
CAT delay: 70,
Option "Satellite mode" checked, all other options unchecked.
I usded a C-17 compatible home build CAT interface (see sub folder "Icom" in
the SatPC32 program folder) and a Prolific and also a FTD single port
USB-to-Serial adapter. Both adapters work. It is most important, however,
to use Vista and Windows 7 compatible drivers.
My PC has a genuine serial port and 2 additional serial ports on a PCI card
and they work also with 32-bit and 64-bit Windows.
For detailed instructions read the "Hints[Radio] ... for Icom users"
(SatPC32 menu "?"). Regarding Vista and Windows 7 compatible drivers for the
USB-to-Serial adapters see my website www.dk1tb.de, English page
"Downloads", "Vistad and Windows 7 Compatiblity".
