The reflex circuit
in this radio has a problem with the reception
of stronger stations. A strong aerial signal
causes the rf/lf tube (E444) to overload and
switch to anode detection. The signal then goes
directly to the control grid of the output
valve. Volume control is then no longer
possible. The automatic volume control (AVC)
also does not function properly in this
situation. The AVR only works on the mixer tube
(AK2), making the situation even worse.
This problem can
only be solved by using an antenna attenuator in
case of strong signals or by using a small
antenna.
At the time the radio was produced this problem
must have existed too, but to a lesser extent.
Transmitters were not as powerful as today, and
modulation was not as intense.
