TRF receiver with reaction control
with brown bakelite case and cardboard back. Made since
1938 by a number of companies in Germany, Austria and
Poland.
Lorenz came up with the best design of a low-cost radio
and also played an important role in its further
development. The receiver only has two valves: the
rectifier VY2 and the VCL11 triode/tetrode. Hungary had
its own version of the DKE, the Orion
011 Néprádió.
Nick-name for the radio was
"Goebbelsschnauze", or Goebbels' snout.
The left
knob operates the input coils coupling, the right knob
operates the reaction variable capacitor. In the middle
the tuning knob with a 0-100 scale in white (200-600
meters) and red (800-2000 meters). By turning the tuning
knob to the red part of the scale, the radio switches
from medium to long wave.
There is also a battery version. An
identical version of the
radio, the DKE50, (without the eagle and swastika) was produced after the war until 1950.
The loudspeaker is made from
synthetic resin bonded paper.
On the right the silver
coloured VCL11, on the left the smoothing
capacitors and the VY2 rectifier. Below the
smoothing capacitors a simple on/off switch is
visible.
Operating voltages (110-130, 150
and
220-240) can be adjusted by using
the taps of the ballast resistor in the middle.
Four sockets for antenna
and earth (left) are situated below the ballast resistor.
An adjusting screw for grid voltage is situated between
the on/off switch and the sockets.
