Hi
All radios with a analog CAT port can be used, RS232, CI-V etc. There is a few new radios which only have USB CAT, they can not be used.
You can test how it will work if you connect a serial cable (RS232 ) from the PC to the radio without Remoterig. If you do not have a RS232 port at the computer you can use a USB to serial converter.
