mrjbernard,
You're way off base. There's absolutely nothing wrong with using an AM set up, and there would probably still be a lot more of them if people didn't believe as you do.

The fact that a transmitter is AM has nothing to do with the frequency on which it broadcasts, and an AM transmitter on 72.850 (channel 53) will do the same thing as an FM transmitter on 72.850.
