The receiver is a single conversion superhet receiver covering the frequency range 100-156 Mc/s. The set is a single channel crystal locked receiver, with front panel tuning to obviate quick channel changes.
Being crystal locked, the receiver had minimum appeal for post war users. Frequently these receivers were converted to vfo operation, the operator having to track the aerial and oscillator circuits for peak performance.
The R1392 has 15 valves, functions including 2 rf amplifiers and 3 if amplifiers, as well as a bfo stage. The audio amplifier is a 6J5, designed to drive headphones. Line output at 600 ohms is also available.
The power supply was external to the receiver, and was usually a Type 3. (Power requirements were 250v (80ma) HT and 6.3v (4A) L.T.
The receiver would have been an easy way to receive on the 2 metre band. (144 Mc/s)
The R1132 is somewhat similar, covering the range 100 -125 Mc/s, with vfo control.
