Designed for FM and HDFM radio broadcast, Res-Ingeniums FM550-108 FM pallet broadcast amplifier supplies CW output power from 500 W to 600 W while using Freescales MRF6V2300NBR1 LDMOS transistor. The Class B component offers harmonic suppression of -

I built an FM radio transmitter (if you need the schematic I will scan it) and every once in the while use to broadcast some music. The problem is it only broadcasts within a very (I mean very!) short distance. How could I increase the distance? I am
