It was great meeting you, Joe. The reason the Zenith 'skips' most channels is that the motorized tuner makes use of presets. Whoever installed it back in the early '70s set it up for the local channels received in the area (2, 4, 5, 7, 11, 25, 38, 44, 56, etc.), installing a little placard in the tuner identifying what channel the preset was set for. I never got around to figuring out how to re-tune the presets for other channels; the Fine Tuning knob didn't seem to do a whole lot, and I had no idea what the controls on the back of the tuner might do, so I didn't mess with them. Hopefully, it shouldn't be too hard to figure out, and most VCRs and such at least offer a switch for channel 3/4 output, so the 4 preset should do the trick. Good luck, and have fun!
