mon, may nakuha ka na ba ng FM |TX. I suppose you want to receive it in an ordinary FM radio. The problem is really keeping your TX frequency stable. It is best to have a xtal controlled oscillator which most wireless mic type do not have.

I am in RC electronics and we use FM TX at.5 watts lang ut can be picked up by our dedicated receiver at more than a km up in the air.
