I don't know if this is what your looking for, but I recently bought a wireless microphone from Radio Shack that broadcasts on an unused FM radio station.
It is small (about  1 inch x 0.5 inch x 0.5 inch), and it has a clip on the
back as well. You tune it to the frequency you desire, and it costs $20.
If you haven't already, maybe you should consider it.
