In my earlier response to Dick Granges' complaint about WNBC's broadcast of a stereo signal, I missed an obvious clue in his note. He said that when he turned on his decoder that he got the TV audio in one channel, and WNBC-FM in the other. This is not possible to do with the "main" audio channel, as the stereo signal consists of a Left+Right signal (what non-MTS TVs decode), and a L-R signal. If the station was really broadcasting one program on the left channel and another on the right, mono TVs would hear garbage. What I think has happened is that Dick's decoder is set to the "both" position. My decoder, along with most others, has an option where you can hear mono in one channel and SAP (secondary audio program) in the other. I have heard elsewhere that WNBC broadcasts their FM station in the SAP signal. Dick should check the settings on his decoder to make sure he is listening to "main" and not "both". Steve Lionel
