Fu.H.E.d Telefunken WW2 German Army Monitor Receiver

A whole series of such receivers was developed in 1939.
They had different frequency ranges.
This one has a frequency range of 25.5 - 61 MHz.
Lower part of the VHF area.
It was used extensively to intercept enemy communications.
A lot of resources were used for this.
The advantage of this is that it was done in seconds to scan a large frequency range.
Then they could use the fine tuning to fine listen to what one has found.






It uses 2V and 90V DC, so here I use a NA6a as power.
