Yeah, they do, but that doesn't mean you get it from your local affiliate. The time is not on a line that is normally broadcast, like closed captions are. It's up higher in the vertical interval. Typically, locally generated test signals are placed there by the time it's broadcast. I remember some years ago that channel 5 in Boston had test signals there but channel 9 across the border in New Hampshire transmitted the network time code. (These are both ABC outlets.) None of the Boston stations transmit the time code, so I dropped the idea of building a decoder for it. Bob Clements, K1BC, clements@bbn.com
