Hello Paul, 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": Model: IC-821H, 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". 55 + 73s, Erich, DK1TB ----- Original Message ----- From: "Paul Delaney - K6HR" <[email protected]> To: <[email protected]> Sent: Sunday, February 06, 2011 7:06 PM Subject: [amsat-bb] Doppler Tuning IC-821H > > I just acquired an ICOM IC-821H as I plan to build a satellite capable > station.
