Description: Picture, description and specifications.
The Johnson Viking I transmitter was made from 1949 to 1952, and was sold as a kit for $209.50 or assembled for $259.50. It is crystal-controlled and covers the 160-10M amateur bands. The tube lineup is a 6AU6 oscillator, 6AQ5 buffer/doubler, 4D32 final amp, 6AU6 microphone amp, 6AU6 driver, and push-pull 807's in the modulator. Power input to the final is 115W CW and 100W AM, although some examples use an 829B as the final with inputs of 100W CW and 85W AM. The final amplifier is tuned continuously by a pi-network using a rotary inductor ganged to a variable capacitor, and the oscillator and driver are bandswitched.
