There is a good possibility that the 144.16 is not the primary frequency, but a sub-harmonic of the output (times 4, 5  or 6). Time to be a good neighbor, and help them with it. Many folks, for whatever reason, think that only they can receive their particular wireless microphone. When I show them that I can hear it on a $ 30 radio, they are stunned.

But do let them know they have a problem.

A local church has a FM microphone that is transmitting on 144.160MHz, and I can also hear it 20kHz above and below that frequency. I'm not sure if 144.160MHz is the principal signal or if it's some mixing product. Would anyone know what brand/model wireless microphone would cause this?
