[ARC5] U boat radar detector

[Robert Eleazer]

"Early British aircraft used the 176 Mc ASV Mk II radar until the Germans
developed the Metox receiver which detected the signal from the airborne
radar thus allowing the sub to dive and escape detection."

When the microwave radar came out the Germans noted that the Metox set (made 
in France by the Metox company) was not detecting the radar and decided that 
the Allies had found out how to home in on the LO of the Metox receiver and 
so turned them off.
