This is the stereophonic counterpart to the transmission system structure A52-E for determining the physical origin of the telluric signals. The distance between structures is approximately 200 miles.
The major effort was digging guy a guy anchor hole five feet deep in the rock to replace a dead end guy on a telephone cable facility. Also, the effort was made to gather up approximately five miles of abandoned open mile line to use in constructing the new transmission structures. Much more is still needed and no availability has been found yet.
Broken poles and dangling wires, missing guy wires, etc. being cleaned up and preparations made for installing the new open wire facilities for the Alexanderson-Beverage Earth Signal Receiving Antenna. (ASW – Advanced Seismic Warning System). The repairs were done by myself (Eric Dollard) and Justin Miller (member of EPD Labs).
Part of this project consists of removing two miles of no longer used well pump control lines of open wire construction. Wire is 8 awg open wire subscriber telephone line. This wire will be used later as well as the cross arms on the overall Long Line Project.
This is a continuation of the previous DBR photo gallery. This facility amplified the signal and regulated the gain of the auxillary repeaters along the line. Repeater spacing 50 miles. Shown is the O Carrier terminal facility equipment from inside the building shown.
