Hamtronics 220MHz Exciter.

Tuned and Tested; 1.54Watts out at 13.6VDC (at less than 400mA).

Please note this is NOT easily frequency agile. It is currently programmed for 224.620MHz. Hamtronics is no longer in business and the programming software was never freely available.

Pre-Emphasized and Flat audio inputs (tuned to provide ~ 4.1kHz deviation with 40mV pk-pk on pre-emphasized input, and 1V pk-pk on flat audio input for full 5kHz deviation).
