»DX-60 Phone & CW Transmitter: The DX-60 Amateur Transmitter with its many design features offers more in quality, performance, and dependability than any other unit in its price and power class! Superbly designed throughout, the DX-60 with its high quality components, clean, rugged construction and thoughtful circuit layout makes it an ideal 'first' transmitter for the novice.
Construction proceeds smoothly from start to finish with the complete, informative instructions furnished. All parts are easily identified and a precut, cabled wiring harness eliminates much of the tedious wiring. The completed unit with its neat, functional panel layout provides for maximum ease of operation.
Circuit-wise, the DX-60 features a built-in low pass filter for harmonic suppression, neutralized final for high stability, grid block keying for excellent keying characteristics and easy access to crystal sockets on the rear chassis apron. A front panel switch selects any of four crystal positions or an external VFO.
Controlled-carrier modulator and silicon diode power supply are built in. Single knob bandswitching for 80 through 10 meters and pi network output coupling provide complete operating convenience. A high-quality panel meter shows final grid or plate current to aid in tuning. In every way, the DX-60 represents an outstanding amateur 'buy.' May be run at reduced power for novice operation. Less crystals.
SPECIFICATIONS: Power output: 90 watts peak, carrier controlled phone or CW.
Output Impedance: 50-72 ohm (coaxial).
Output coupling: Pi-network.
Operation: CW or AM phone, crystal or VFO control.
Band coverage: 80 through 10 meters.
Power Requirements: 105-125V, 50-60 cps, 225 watts.
Dimensions: 13¼' W x 11½' D x 6½' H.
HG-10 VFO: The new Heathkit HG-10 VFO covers from 80 through 2 meters with each band separately calibrated on a rotating drum-type slide-rule dial. The circuit uses the popular series-tuned Clapp oscillator with a cathode-follower output for isloation and regulated plate voltage for maximum stability. Its vernier tuning has a 20 to 1 gear drive […] and there's a 'spot' switch for off-the-air-tuning.
The circuit is designed for grid-block keying with the new Heathkit DX-60 or for cathode keying with other transmitters. Everything is mounted on a rigid steel chassis for superior mechanical strength and freedom from chassis instability […] and it's all wrapped up in a handsome cabinet to match the DX-60. Power is obtained from the transmitter […] just plug it into the DX-60, or make simple changes to use with other transmitters. All cables are supplied.
Specifications: Band coverage: 80, 40, 20, 15, 10, 6 and 2 meters.
Load impedance: 50 K ohms or more.
Output voltage: 5 volts R.M.S. or more, with no load.
Output connections: phono plug.
Front panel controls: Function Switch (Stby/Opr/Spot), VFO tuning & Band selector.
Tube complement: 6CH8--oscillator--cathode follower; OB2--Voltage regulator.
