[R-390] R390A Turns Counter BFO option?

Bob,

The bug eye counter is referred to as a micro dial after company that made 
the counters. It was used on receivers that were used to copy RTTY. The dial 
has no relation to BFO pitch and dial count. But it offered a count that 
would let you dial the BFO with better resolution than the stock knob. Once 
you found the correct counter number to use for your receiver you could redial 
and thus retune for RTTY operation faster than without the dial. It was 
popular on a lot of receivers used in a lot of applications. The signal corps 
used a lot of RTTY links and used the dial. The spooks used a lot of the 
dials also. NASA used a lot of the receivers as standard communication equipment 
to tie links into military nets around the world to communicate with the 
military for launch, recovery, tracking and weather information.

Enjoy you historical receiver.
