Thanks Dave, that clarifies it for me, and thanks for the attached example. Ive heard of tones being used before in itc devices. Ive recently heard that Bill Chappell uses two sweeping tones in his inductive cross talk device. They sweep fast back and forth in opposite directions from each end of the speech band. Sounds like a slow modem, but as you say, it eliminates the vocal factor from the argument! JEFF
