FuMB10 - Borkum a crystal detector passive warning receiver covering 7 - 300cm wavelength transmissions. https://books.google.co.uk/books?id=LoeQCgAAQBAJ&pg=PA343&dq=FuMB10&hl=en&sa=X&ved=0ahUKEwjL87GYs5zKAhVCPxQKHc2gBWQQ6AEIRDAG#v=onepage&q=FuMB10&f=false (100 Years of Radar page 344). Many WW2 German radars received geographic location nicknames. E.g. Flensburg (Germany), Naxos (Greece). The FuMO series were I believe active radars; see table at the bottom of the same page DaveP
In the fascinating U-boat logbook, I see several references to "Borkum" - as in:
Fu.M.O. continuously manned with Borkum all around sweep every 5 minutes.
In addition to "Borkum", I find "Fu.M.O." cryptic, though from context it may be a reference to a radar set. Have I guessed right?
