[TenTec] Orion AM ALC

[Rob Atkinson]

Hi Jerry,

Kindly expand upon your statement re "DC offset."  You lost me with that one.

I think what you are writing below has to do with vacuum tube plate
modulated rigs?  A number of asymmetric peak limiter processors for AM
have come to market since the early 1970s.  Yes, some of the older
broadcast rigs had a hard time with them.

Merle:  Too bad Ten Tec assumes everyone wants to be limited to 100%
positive and negative.   The power is in the audio.
