RS 1/20 DM/43 - FuMB5 "FANO" Radar Detection Receiver! This was used by most U-Boats (as well as larger vessels). The SAMOS heterodyne receiver was used to detect enemy radar beams and find their location. It was used primarily for maritime service on U-boats and large battleships such as the Bismarck and the Prince Eugen.
The most frequent use was on U-boats, since the detection of enemy radar predicted an eminent attack, allowing the U-boat to dive and take evasive action. By attaching a direction finder antenna, the receiver can also be used to find the source of enemy radar signals. Similar to the SAMOS radio, but with a frequency range of 400 to 800 MHz in four overlapping ranges. With harmonic operation, reception up to 1600 MHz. Made of aluminum and steel, this.
Er is in EXCELLENT used condition! Though there are some marks, scratches, dents and wear to the outer casing, it still retains 90% of its original wartime paint! Appears to be fairly complete internally, and mechanically functional!
I have not tested it for electrical functionality, but it should be a good candidate for anyone wishing to get it to work. All switches and dials work as they should. Data label is 100% complete, as well as an internal tag indicating " ncv ", for "the manufacture " Rohde & Schwar z.
The two lower case attachment bolts are missing, but those could be replaced. I have shown its location in the sound room of U-995 in the last image. A VERY RARE radio it would make a FANTASTIC addition to.
