When TV cable suddenly started stretching wire in big cities, in the late 1970s or so, I happened to notice that Little Rock, Arkansas, had a very active Cable FM Band, including BBC World News, Bureau of Standards Time, and custom radio stations from individual broadcasters.
Coming home to my own town I found that cable FM was being used to provide stereo audio for major TV channels, but nothing of the radio kind.
Since then it seems nothing at all has been done with cable FM in this market, but the potential that I first realized caused me to register the call signs KDX with the intention of starting a cable FM radio station.
What actually happened is that KDX became a streaming station on the internet as well as a part 15 radio station.
Now we come back to the question of cable FM, these many years later. Does it still exist? Is anyone doing it?
