AR-3

[Kenneth G. Gordon]

I had an AR-3 once. It was my first ham receiver. Never could get the 
BFO to work. Now, nearly 50 years later, I figure out why: the BFO is 
part of the audio stage. It is hooked up in a "reflex" connection where 
ONE tube amplifies the audio AND oscillates as the BFO, but ONLY 
when the AF volume is all the way up.

Hmmm...think I should have had an AR-2 instead. At least THAT has a 
separate BFO tube.

Shucks...
