Permanent Restoration of Repeater
On July 3, 1961 the TD-2 repeater stations at Cedar Mountain, Utah and Wendover,
Nevada, were restored to permanent operation 35 days after an explosion
destroyed them on May 28. The new facilities replace the temporary arrangements
that had been quickly se up following the disaster, including temporary towers
and wooden buildings to house the equipment.
On July 5 the K carrier repeater station at Knolls, Utah was restored to
DESTROY REPEATER STATIONS
Early Sunday morning, May 28th, the TD-2
repeater stations at Cedar Mountain, Utah and Wendover, Nevada and the K carrier
repeater station at Knolls, Utah were blown up and virtually destroyed, severing
both the central transcontinental microwave and K carrier routes. Cedar Mountain
is the second and Wendover the first TD-2 repeater station west of Salt Lake
City. More than 2200 telephone and telegraph circuits and two television
channels were interrupted.
Many private line circuits were made good
within a short time and the first TD-2 systems were rerouted around the damaged
section by way of Los Angeles within two hours. By Sunday evening, most of the
circuits had been rerouted spare facilities and protection radio channels. One
TD-2 channel was made available between Salt Lake City Junction and Los Angeles
(via Turquoise) Tuesday night, May 30th, by expediting installation of new
equipment on which work was nearing completion. This released some protection
channels that had been used for reroutes.
Portable TE equipment was brought in to
restore service across the breaks. By June 2nd, four two-way TE repeaters had
been set up at each of the microwave locations to restore two message, one
television, and one protection channel. Portable scaffolding type towers were
used to support the antennas.
Within one week after the blasts, temporary
wooden buildings were constructed and six two-way AC-operated TD-2 were
installed at each station to maintain normal service until a permanent one can be
made. The temporary towers with parabolic antennas will be used until permanent
towers and can be replaced. Permanent of the TD-2 stations is expected to be
completed by July 18.
According to recent news reports, the FBI believes the sabotage
was the work of two men who stated their intention was to destroy cartels, such
as the American Telephone and Telegraph Company, and to focus attention on an
organization called "American Republican Army" which advocates political
overthrow of the United States.

at the Wendover and Cedar Mountain locations.
