Hey again everybody--I just took delivery of my own copy of "This Thing Called Broadcasting" (by Goldsmith & Lescarboura, published in 1930 by Henry Holt and Company). The book has the best account I've ever read about how transcontinental broadcasting became possible and how it all came together from a logistic standpoint. Here's a section about how the link was finally made to the Pacific coast (from pages 170-171):
For a Permanent Country-wide Hook-up
For a time the country was divided into two definite radio audiences, namely, that east of the Rockies, and that of the Coast States. On special occasions both audiences were joined together through the use of the transcontinental telephone lines, but so great was the expense that a combined audience was out of reach of routine programs. [WOULD LIKE TO KNOW MORE ABOUT THOSE 'special occasions'--DATES, CIRCUMSTANCES, ETC.]
However, the demand for a national audience by the largest sponsors brought about the permanent linking of both radio groups on December 24, 1928, when a nation-wide program inaugurated the twenty-four-hour coast-to-coast circuit of the NBC. The final link in the chain between Denver and San Francisco required intensive work for more than a year, and was the final operation in connecting by special wires the fifty-eight transmitters then comprising the NBC chain.
The first span in this transcontinental link was completed on June 1, 1928, when the line was extended from Omaha to Denver. Maintenance of the permanent circuit was estimated at $220,000 a year [ROUGHLY $2.7 MILLION IN 2008 DOLLARS]. Successful installation of this circuit was regarded by engineers as an achievement of the first magnitude, recalling that the first telephone circuit between New York and San Francisco was not completed until 1915, and that it was comparatively simple to instal (sic) telephone circuits in comparison with permanent, specially engineered lines capable of carrying musical tones without distortion. Experiments were made for eighteen months before the circuit was ready. Extensive tests were made to assure uniform transmission of programs to and from the coast.
The new circuit served two intermediate transmitters, KSL Salt Lake City, and KOA Denver, and provided the entire country with network programs. Amplifiers or repeater points in five States serve to check the transmission of each program as it passes along the 1,600-mile line to the Pacific Coast. From Omaha the circuit goes to North Platte and from there to Rawlings, Wyoming. Next it is checked at Salt Lake City and then at Winnemucca, Nevada. The next tests on the transmission occur at Sacramento, California, and then it goes into San Francisco for distribution to the NBC Pacific Coast network.
It was estimated at the time of the inauguration of the permanent national hook-up that the NBC Eastern circuits served 69.4 per cent of the radio audience in the United States, while the Pacific Coast system reached an additional 12.1 per cent. The new link added 1.2 per cent and brought to listeners in the mountain district the same programs heretofore heard only in the East and on the Pacific Coast. Before this link was made, these listeners heard only special network programs and events of national importance.
