Key Features

The FM 100C can serve as a reliable 125 watt stand-alone FM transmitter
Computer-optimized phase locked loop greatly improves low frequency response
Contains a 250 watt MOSFET as the output device
Optional N+1 board allows selection of up to 10 different frequencies in local or remote locations
Frequency range of 87-109 MHz digitally programmable in 10 kHz increments
Performance specifications feature a dynamic range that rivals CD players with harmonic and intermodulation distortion values so low they are virtually immeasurable.
