Pick a band...new 80, 40 and 20 meter SSB transceivers from Heathkit! These single band transceivers have more features and better performance ... at one third the cost of three-band units. Buy only the bands you need. Employs a crystal filter type SSB generator for clean operation. Features include Automatic Level Control (ALC) and low frequency VFO (1.5—1.7 mc) for greater stability than comparable units. Vernier tuning assures smooth and accurate frequency location.
These transceivers are designed for easy assembly and include a heavy-duty circuit board, rugged steel chassis and wiring harness, a welded and braced one-piece steel chassis & cabinet, and gimbal mounting bracket. Provision has been made to accept a Heathkit HRA-10-1 100 KC Crystal Calibrator as a plug-in accessory. The transceivers use the GH-12 push-to-talk microphone and operate with the HP-13 (DC) or HP-23 (AC) power supplies or the Heathkit HP-10 (DC) or HP-20 (AC) power supplies.
