found the glitching issue, need help solving it

FM and AM are in the same carrier band, both are susceptable (sp?) to mechanical vibrations. This is supposed to be the advantage of the newer 2.4GHz systems.

As for the problem. does you antenna wire run under the chassis and then up through the antenna mount? Is the receiver padded from the aluminum chassis? I am with the guy above who suggested trying a regular receiver pack once to see what happens. be sure to remove power from the Ubec when you do this experiment.

That is true, but AM has the actual signal modulated on the top of the carrier frequency, which is the worst place to be noise-wise. FM shifts the carrier frequency by the signal amount. Also, FM [should] chops the top and bottom on the carrier wave. These together help eliminate a lot of RF noise. But if the noise (or harmonics) is close enough to the radio frequency and is powerful enough, FM still suffers. But AM is worse to be sure. Granted, I am assuming AM and FM radios work like regular radios (the music kind).

Aside from the 2.4GHz systems being at such a high frequency, the radio and receiver employ error correcting in the digital packet transfer (at least in the ones I am familiar with). Both of these together make for a very reliable link.
