Re: Radio Survivior #051 on AM Carrier-Current History!

Oh yeah, I was surprised to see that they were doing a whole piece on carrier current, mainly historical, starting with the gas pipe networks, where college students broadcast AM radio into gas pipes in their school in the 1930s. Somehow the method for carrier current broadcasting got changed to a building's electrical wiring and the practice spread and became popular enough by the 1970s and '80s, that record companies courted them and sent music to be played. Nowadays there are probably only a few carrier current stations in the country!

I do carrier current broadcasting to my neighborhood and I love it! I found out about it long ago when we would go to our local drive-in theater and they were running a station at 530 with the movie's audio on it. The station could be heard in that neighborhood too, and way up the road, and I thought that was very cool! About the same time I read about carrier current in electronics magazines, but didn't know how it was done or what kind of transmitters were used.

I read Radio Survivor regularly, lots of articles about smaller radio and sometimes pirates or squatter's radio, they're not afraid lesser known topics or other types of radio than commercial broadcasting.
