Perhaps there was a lost opportunity to make the new channels in the 8.3khz radios FM?
I've heard old stories that the reason aside from history was that in the event of a double, with AM you hear both. But with FM the stronger signal may capture the receiver and you would not know that the second guy was there.
HAM's definitely are better at communicationg than the aircraft folks.
Another issue with 2M Ham radios is that you need, at a minimum, an FCC amateur technician license to transmit legally.
