My Midland 79-290 shows a FM mode when toggling through the different modes (AM-USB-LSB SINCE I DID THE CHANNEL MOD.) It receives and transmits on AM though, even when the indicator shows FM. I, believe that there is simply a part of my radio disabled to be accepted by the FCC for use in our country. Since it also has the 10 meter band, I figured that it may very well have a frequency discriminator in it, but it is bypassed. Or I could be completely wrong. Any info would be appcd!!
Thanx Guys,
Dan

Hmmm...Do you have "swing" on FM? If so it is most definatly on AM. If you have no swing when modulation is presented to the mic on FM , it is deviating correctly. The FM is crappy on those radios and you may hear AM on it.

Rule...AM , swings with audio , FM no swing with audio (in simple terms)
