Receiver Type Ukw.E.d1. (Germany)
The German HF receiver type Ukw.E.d1 was a component
of Wireless Station No. Fu.3 and Fu.7 in the German Army, and was used by
signal troops and armoured troops for air-ground co-operation. It
would have been used in conjunction with transmitter type 20 W.S.d.
The receiver covers
a frequency range of 42.1 - 47.8 MHz and uses 9 side-pin valves type RV12P2000.
The internal construction is very advanced for
its time, using a system of aluminium alloy die castings to contain and screen
the circuits. The valves are plugged directly into the screening sections
of the castings with their bases flush with the top surface.
