The FHM-3 hand mic incorporates a high gain, wide frequency response condenser microphone element and with its ergonomic design and a low resistance PTT button, the FHM-3 with the TRS/RCA connector is a perfect complement to the FLEX-6600, FLEX-6600M, FLEX-6400 and FLEX-6400M software defined radios.
Notes:
The bias voltage setting in SmartSDR will need to be enabled to use the FHM-3 hand mic.
The FHM-3 requires the Y Cable Kit (https://www.flexradio.com/products/maestro-c-y-cable-kit/) in order to function with the Maestro C.
