[ARC5] Re: [Milsurplus] South America Mil Radio in WWII?

[Gordon White]

Somewhere in my research years ago I found reference to using the LF 
receivers in blimps and PBYs operating
out of Coco Solo in the CZ and out of Newfoundland.  Of course  the 
four-course Adcock radio ranges were in use then, at those frequencies.

You may be too young to remember, but there were radio dramas and even a 
popular song about "being on the beam." The pilot would hear A or N in 
Morse  .- or -. depending which side he was on and a steady tone when 
right on the beam. I well recall the difficulty when crossing a station 
in being certain which outbound leg you were on, especially if the beams 
were not arranged at 90 degree angles.

I think it was the fact that in South America the Adcock ranges lasted a 
lot longer than in the U.S. after Omni and DME came in that kept the LF 
receivers in USAF planes into the 1970s.
