AT&T Coaxial Cable Network

T

The King Bee

Where can I find information and maps of the old AT&T Television Coaxial Cable System? I'd like information such as build dates, what times the network reached certain cities, and the like. Here in Louisville, we're approaching the 60th anniversary of regular TV service (WAVE-TV, 11/24/48) and I'd like to share this history with my broadcasting students.

(I am aware that in 1950, Louisville was the closest coaxial cable point to several cities, including Nashville, TN...WHAS-TV in Louisville sent the TV signal south to WSM-TV via a 180 mile long microwave link with five repeater stations to help open up Tennessee to television until the coaxial network was extended to the south.)

It's not comprehensive, but there is a lot of interesting information there (including some maps).
 
Not only that....I would also like to see some vintage photos of the inside facilities of those mircrowave radio-relay stations that used to feed all of the television and radio networks from the 1950s up to the 90s....particularly the ones located in Botkins,Fletcher and Springfield, Ohio.

Whenever you travel down the highway,most (if not all) of these 300 some odd foot towers have been abandoned..some with the humongous horn shaped antennas from on top of these massive structures removed leaving only a stump of what it used to be. Many of them don't even use their beacon lights at nighttime anymore.
 
I have to ask: From what aspect of this massive network of coaxial cable lines, if any, did the "pinched" 50 Hz-5 kHz "telco" audio sound as heard on network feeds in most places except New York City and Los Angeles (but only, in the latter city, on shows that originated there) up to early 1978? Anyone who's seen network promos from before and after 1978 on places like YouTube will know what I mean, audio-wise.
