[ARC5] Type 185 Radio Receiver?

Mon Jan 8 02:31:38 EST 2018

Hey Bart!  I have a reproduction P-51 pilots manual and it talks about the
"Detrola" nav receiver.  The pilot is reminded that he can't *talk *to
towers or range stations with it !  HiHi
I think those receivers use 28 VDC for the tube plates.  Simple..

That "A-N" system was simple and apparently effective back then, a good
solution as technology developed...  Those grab-and-go receivers (etc.)
must have helped keep the dry cell industry going....yikes!

The guy who has this 185 receiver is flying an F4F so I hope he has
something better in it!
