The Lafayette Model HA-1200 is a compact, self-contained transceiver designed for the 2-meter band. The universal power supply makes the unit ideally suitable for operation as a 12 volt DC mobile unit or fixed station operation from a 117 volt, 50/60 cycle AC power source.
Requires an external 8 ohm speakers.
