For 2 meter up- and downlink (the normal mode for ISS), you must use the special ISS version of SatPC32, SatPC32ISS, which puts the transceiver in "split" mode, rather than satellite mode. You must also provide a handshaking signal to your serial port to prevent the software from trying to change frequencies while transmitting.
See the file SatPCISS.txt in the program folder for details.
Good luck!!

Is SATPC32 supposed to switch the IC-910 to the correct VHF TX/RX frequencies (as it does for sats) in mode U/V? If so, how do you do it. I was just playing with the radio and software and it seems to command the RX frequency but the TX frequency isn't correct. I was thinking about trying to talk to the ISS sometime.>Thanks
