From United States Army in World War II,
The Signal Corps: The Outcome, Thompson and Harris, Office of Chief of
Military History Untied States Army, 1966, pp. 5, 345, 346...
"Gen Stoner headed the Signal Operating Services during WWII. The
responsibilities included the Army Command and Administrative Network (ACAN),
signal security, training, and organization.
He was considered a communication systems specialist and continually
emphasized communications security: "...protect our communications by
every means at our command. We of the Signal Corps are charged with the
security of communications, but we need the full cooperation of everyone
who comes in contact with those communications, either directly or
indirectly...Aside from the fact that one slip, one bit of carelessness,
may endanger an entire operation, the compromise of a system invariably
means the loss of hundreds, even thousands of manhours that went in the
development of that system..."
This exciter was used in a Titan Missile Silo
for tactical communications.

interested in the exciter ..
It was originally developed in 1961 by the U.S. Navy for the Radio

exciter T-827( ) /URC unit of these equipment's. USAF purchased units
and renomenclatured them and in some silos they were painted black for
some reason. Developed and originally produced by General Dynamics,
The AN/URT-23( ) is still in use today!!!!
