Any Icom folks that might know if these radios can be programmed manually? I have two of these that were programmed some years ago that I now need to make changes to (just changing some tones). I have the programming software and cable, but am having problems with serial port chipset / drivers (PL2303HXA driver, running on Win 10), so haven't been able to get it to work. User manual doesn't address manual programming. Thanks in advance if you can help, or have driver suggestions.
Thanks!
