You used some form of audio processing in the AM Max II and I am not sure if it was something that you offered as a separate product or not. Us old hams that play with AM transmitters on the ham bands need some form of control over the frequency response to limit our bandwidth. There are times when 4.5 khz is the max audio frequency that we want our transmitter to see and there are the other times (3 AM

Was it ever a product by itself?
