[Milsurplus] LO radiation

Re:
>> Any specs on the Metox?

Metox-Empfänger R-600, 113-484 MHz. to counter the ASV Mark II radar at 200 
± 15 MHz.  When traversing the Golf von Biskaya they were being surprised on 
the surface at night with no warning from the R-600, because the Brits had 
gone to the ASV Mark III radar at approx 3000 MHz.  A centimeter radar was 
recovered from a wreck the night of 2-3 Februar 1943 bei Rotterdam and all 
was made clear.  Before that they were concerned that the Metox might be 
radiating, as it had no rf stage.  They conducted tests with a plane, and 
found it did indeed radiate and could be detected in 12 sea miles at 500M 
altitude, 18 sea miles at 1000M, and 25 sea miles at 2000M altitude.  On 
this basis they pulled them from service. (Which in hindsight didn't matter 
as no-one was listening for them.)
