Does anyone know which three stations were on cable in the early 70s? I'm going to guess it was WKZQ, WMYB and WNMB. Or perhaps WLAT-FM could have been one of them.
We had broadcast stations on channels 2-8. NOAA Weather Radio was on Channel 9 with a camera going across gauges with ads at both ends. I forget what was on Channel 10. The list of channels, which was the size of a business card, showed "FM Music" on 10, 11 and 12 but that was an old list. The music was on 11, 12 and 13.
