 + 
 +==== General ==== 
 + 
 +  ​***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. 
 + 
 +==== Receiver ==== 
 + 
 +  ***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). 
 +  ***AGC:** audio derived 
 +  ***I-F:** 11 MHz on 80 and 40 meter models, 14.32 MHz on 30 meter model, 6.14 MHz on 20 meter model. 
 +  ***Audio:** 300 mW @ 4 ohms. Built-in 4" speaker in top of cabinet. 
 + 
 +==== Transmitter ==== 
 + 
 +  ***RF Output:** 3 watts, no external adjustment. 
 +  ***T/R Switching:​** solid state, full break-in. 
 +  ***CW Offset and sidetone:** Adjustable 400-1000 Hz sidetone automatically tracks offset frequency. Sinewave sidetone has internal adjustment.
