[Milsurplus] BC-9 Loop Test: Scratching My Head.

[Richard]

I think someone said the last change was higher voltage on transmit.  
Some dim bulb who knew a thing or two, but not enough, probably proposed 
it for more output, and it was accepted by a supervisor who knew less.  
I've seen this happen on big electrical equipment, with disastrous results.
