ICOM R20
 

I just purchased an R20 that I want to use more for signal detection
rather than receiving. I was disappointed to see that it will not
demodulate SSB or CW at 470 MHz and above. (It's easier to hear the
signal in these modes.) Does anyone know of a mod that can fix this?
Also, are there any mods out there to unblock it?

Thanks,
Jim
