Bob, As I understand it now -- after some expert tutelage -- in your scenario you would see just what you describe. Indeed, that was what we have been seeing with the 1610 test signal.
All of the other signals I was describing were simply the result of the interaction of the uncommon situation of a steady test tone signal with the receiver BFO. Switch everything back to AM and quit trying to be so clever and presto, you have a 1kHz tone on 1610. It would seem under normal circumstances because of proximity to the carrier, no one would be looking so closely as to see those offset signals. And of course with a normal AM signal the modulation is all over the place so what you hear and see does not give the impression of offset carriers. What I failed to recognize -- amongst other things -- was that last night when I could not hear the 1kHz test tone but could detect the main carrier, I did not see any apparent offset carriers. Tonight when the audio was strong, those signals were there. When talk of 1609 and 1611 began, sure enough, there they were right in front of me. Sorry I muddied the water with my details, should have stuck to something I understood, like, "I heard a tone too."
