2KC dial calibration--6" of bandspread
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.
