[R-390] Wullenweber Coupler CU-1280/FRD-10A(V)

[Les Locklear]

They are probably as rare as the LF Converter for the R-1051's.

I had one of those antenna couplers, ran pretty hot when in use. Got rid of it years ago. Nicely built though.

Keep trying, someday somebody will find one that wasn't burned or shredded.

  Anchorites,

  There have been requests before for information about the receiving  
  antenna coupler used in the "Elephant Cage" Wullenweber direction  
  finding system:

  CU-1280/FRD-10A(V)

  If there are any manuals out there, I'd appreciate hearing about them.

  For pictures of the coupler, and other info about the FRD-10, see:

  Roy
