We recently looked at the Knight-Kit Star Roamer Receiver from 1964. It was a beginner’s general coverage receiver and was quite popular. The February 1965 issue of Popular Electronics announces another popular general coverage receiver for beginning SWL’s and hams, the Heathkit GR-64 shown here. It covered 550 kHz through 30 MHz in four bands, and made do with four tubes, a mixer-amplifier, IF amplifier, detector-audio amplifier, and audio output. The power rectifier consisted of two silicon diodes.
The kit retailed for $39.95. The assembly manual is available for download at this link.
