Frequency Coverage: VFO tuning of any 50 kHz segment of CW sub-band. Tuning range is selected during winding of one toroid in the VFO circuit.
Frequency Control: Varactor tuned oscillator with potentiometer control. Temperature compensated LC components stabilize VFO.
Power requirement: 12-14 Vdc, 35 mA receive (no signal present), 80 mA receive (S-9 signal), 800 mA on transmit.
Antenna: 50 ohm unbalanced, SO-239 connector.
Construction: Black texture painted clamshell type steel top and bottom. Aluminum chassis, sub-panel and heatsink. One 3.5" x 5" double-sided circuit board.
Board mounted-components: 216 including 4 IC's, 19 transistors, 13 diodes.
Front panel controls: main tuning, RIT, volume, power on-off toggle switch.
Connectors: front panel 1/4" stero phone jack; rear panel SO-239 for antenna, 3 RCA-style phono jacks for key, dc input, accessory dc output.
RIT: +/- 1.5 kHz.
Dimensions: HWD 2.75" x 6" x 6". Weight 2.25 lbs./1.02 kg.

Type: single conversion superhet, JFET mixer
Sensitivity: .25 uv typical for 10 dB S/N
Selectivity: 4 pole crystal ladder filter (1 kHz nominal bandwidth).
