We have all gone fm and everyone says they hear me great but all I hear is the same louder interference. Could someone explain how fm works and what am I doing wrong. Thanks!!

I would guess that a lot of the export radios added FM is an after thought and is using circuits that where made for AM, and they need to filter out all the amplitude modulation then they have a FM part that will decode the frequency modulation. You are still hearing the same interference pass through because it is not getting all the AM out...
What do you hear when you tune in to an AM station in FM mode? I know on my RCI-2990 people can hear me on AM when I am in FM mode...
I don't know the answer I am just taking a crack at it.....
if you mean you don't hear your buddies on fm only hash sounds but they hear you ok somebody may have twiddled the fm quadrature coil.
The only different between modes is the detector circuit.Everything else is the same in any radio. By it's nature an FM detector does not demodulate AM very well at all but you can still hear FM on an AM receiver by what is called "slope detection". As the frequency of the signals varies up and down in frequency according to its modulation, the signal moves up and down within the passband of the receiver's filter. This causes the amplitude of the signal to vary in line with the frequency variations. In fact at this point the signal has both frequency and amplitude variations and an FM signal can be heard for this reason.
You will never be able to 100% completely reject another mode.
yes several people or all say they hear me great all I hear is the higher hiss and buzz but I do see their signal readings the same but no audio?
