I thought the PBY used the DW Loop Coupler with the RU-*.

I initially thought the same thing, Meir, but the RU (actually the GF)
est meter has square rear flanges and has a black face. I'm inclined
o think it's a signal strength "tune to max" meter for the RDF-2
irection Finding equipment - note the white faced meter and the remote
zimuth dial to its right. These are normally mounted on the top of the
oupler, but may be remoted. You can see the L-1678 coupler unit above
he LM-*. Somewhere around there should be a dial that turns the loop
ntenna through a hydraulic rotator. I uploaded a system drawing to
ttp://aafradio.org/docs/RDF-2-1.png if you're interested.
nterestingly enough, the RDF-2 is ancient - it's detailed in that 1936
RL aircraft radio training manual.
