NRS100 - Norwegian Radio Station 100

The Norwegian home guard used mostly German radio equipment after the WW2.
This radio station NRS100 is designed in 1951 by Radiosalg A/S in Oslo for the Norwegian home guard for replacement of the German equipment. 1000 set was later produced by Størens Radiofabrikk in Oslo. Price in 1952 was 855 NOK.




The NRS100 is mounted in a wooden transport case.
Each Home Guard soldier had equipment and weapons at home.
The radio was located at the home of communications officer in the Home Guard Company.

The radio seems to be brand new.
Do not think it has been used.
First MF was tuned to 455kHz, the second MF was tuned to 388kHz.
It worked great after I replaced the capacitors in the second MF transformer.



You'll find the component list in Tore Moe's article in NRHF's magazine Hallo Hallo no. 5 1990

Here's wooden box with spare parts. Tubes and vibrator.




Headphones, microphone and morse key included in the box.
A special power connector to mount a lamp is also included.




The red label says that it is forbidden to listen to broadcast stations.
One had in Norway pay money to the state broadcasting company (NRK) to get permission to listen to the radio.
National Guard did not pay this fee, so it was forbidden to listen to the broadcast stations with this radio.




Here is NRS100 in my radio room and will be tested on air for the first time.
