[GreenKeys] AN/FGC-38 Torn-Tape Relay Equipment

[Nick England]

Indeed, the AN/FGC-38 Receiver Group included 4 reperfs to service 3
incoming lines - for the explicit purpose of changing tape reels (and
substituting for a broken reperf of course).
Maybe Dave's Army tape apes weren't allowed to patch in a substitute
reperf, but Navy tape apes could indeed be entrusted with this delicate
operation :-) :-)

>From the first page of the "Operation" section of the 1954 AN/FGC-38 manual
-
"Since replacing the roll of tape in a particular operating
reperforator may result in the loss of messages,
a spare reperforator is provided in each receiver group.
The spare reperforator in this instance becomes the operating
reperforator while the new roll of tape is being
placed on the reel in the tape container. The spare reperforator
is placed in the circuit in order that any incoming
message may be recorded with no interruption
in the service. To accomplish this, a jack panel on the
front and rear of the receiver cabinet and a patch cord
are provided. Removal of the patch cord from the jack
panel on the front or rear of the cabinet removes the
spare reperforator from the line."
