Ukw. E. m (Ultrakurzwellen Empfänger m) |
|
The Ukw.E.m is a modified version of the Ukw.E.e receiver. It operates in the frequency range of 40.3-44.7 MHz, or roughly the 7.5-6.3 meter band. The Fu 7 configuration overlapped with the FuG 16 Z aircraft transceiver by only 200 kHz. So a new configuration was developed called the Fu5 (Luft), with the 10W.S.m and the Ukw.E.m devices that operated from 40.3 to 44.7 MHz. This is a heterodyne receiver and a Telefunken product. Receiver chassis is contained in a strong case, and has a cover that clips to the front panel. There are no lugs or projections since mounting hardware is built into tanks. On top of the case are a pair of brass stripes for grounding purposes. Two cables provide the necessary connections between transmitter and receiver - one for side tone, and the other for the antenna. |
