[AMRadio] BC-610

[Warren Elly]

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...

73, and AM,
