Here's an idea. How about talking to the senior radio technician on the
military base? Just maybe he/she would have the answer.

Or borrow a handheld scanning receiver. It could well be that a nearby
transmitted signal ,not necessarily on or near 'your ' transmitted frequency
affect the RC receiver (which probably has limited immunity in respect of
strong harmonics/mixing sigs.)

I appreciate the replies, but the problem is NOT with the receiver,
it's with the transmitter.

I admit this was more or less the response I expected, but I really
hoped someone would say 'oh, I had the exact same problem and designed
and built a filter for my transmitter that fixed everything, and I'd
be happy to show you how to do the same'. But thanks for the replies,
I do appreciate it.
