Thanks Lynne and direwolf for taking a look. Jameskg, there were a couple of small tracks marked silence, I guess from the tape lead-ins/lead-outs that have no magnetic material on them. These were truly silent, with nothing much in them at all. I guess that rules out problems on playback.

I don't think it is the pilot tone either, but your idea is that during the recording the cables could have been acting like antennas and picking up on some interference? Unfortunately I looked through the whole show, and besides those lead-in/lead-out tracks not a silent place anywhere to check...crowd noise everywhere in the background, and the same ~16 KHz stripe.

I guess the main thing I wanted to do is rule out FM broadcast...these are supposed to be from the masters...but I am still sure damn curious about that stripe.

Not having the original tapes makes this pretty hard to figure out.
