Product Details:
Rare, WWII jammer transceiver / receiver from 1944. New in the original box!! Apparently, one of the first iterations of a number of jammer projects initiated during the war. Covers 14 to 50 MHz. Designed to allow listening to locate German ground transmissions and then transmit to jam them.

Appears to be a TRF receiver. Transmitter appears to be a 6J5 oscillator, 6AG7 driver and an 807 final. Should be good for a very conservative 20 watts output. Uses a combination of a 2X2 and a 931A photomultiplier tube as a noise generator producing about a 40 - 150 KHz wide signal. Also has a 5Y3 and 5R4 rectifier. 11 tubes total.

Operates on 80 or 115v AC, 400 to 2600 Hz. Includes spare fuses, pilot lights, tuning indicator lamp and a brief operating manual. No technical manual available.

Measures 10-1/4"W x 7-7/8"H x 21-3/4"L.
