[AMRadio] BC-610

Mon Nov 21 15:05:35 EST 2011

Hey Warren,
I wasn't saying they "Don'T" talk back, just that I have not experienced 
that
with the ones I own. I have refurbed and placed several BC-610(*) models
and ran them thru the wringer before letting them go as working units.

I understand "Talk-Back", got an RCA BTA1-M it had the problem
when I got it, checked the frame bolts to all the trannies, removed excess
paint from the frames, put new hardware on them and NO MORE talk-back
from them. Mostly I find the problem to be mounting configuration and 
hardware.

My I Model sealed mod tranny has "talked back" from day one (five years on 
air), reminds me of the
broadcast boxes I was around as a 3dclass endorsed kid reading meters in the 
60ies...

My beast sits 6 feet behind my operating postion...but I've operated sitting 
in front of it as well, and never found the talk back to be a problem...
