A. Trouble Reports
1. The Wire Maintenance Shops in the Washington area have
reported a total of two hundred and forty nine (2149) troubles
for the month of December. The troubles as broken down for
the different locations are as follows:
Signal Center
200
1717 "H" Street
15
OCI
24
Outside Area
10
2. This total shows an increase of nineteen (19) troubles
over last month. The Signal Center had a considerable
amount of 131-B2 table troubles this month which resulted
in this marked increase.
13. Daily Activities
1. The 0 teletype circuit GT-7085 was replaced by
teletype circuit G!2-7420. This circuit was checked out at
the three local signal centers and between each of these
signal centers to the
2. Due to the unfamiliarity of the 0 equipment by our
technicians in this area, troubles that developed have
taken considerable time to repair. Mechanical and electrical
adjustments seem to be very critical.
3. During the first part of the month, troubles on the KW-26
equipments ran quite high. Two core boards were found bad
and several tubes needed replacing. Tubes in all units were
checked in a tube checker, with bad tubes being replaced.
This resulted in numerous troubles appearing shortly after
placing units back in operation. It has been decided that
unless troubles develop , all tube and core board servicing
will be done by means of the marginal check method,
4. A Dial Door Lock was installed on the watch officer's
door "Q" Building as per request, Chief, OCI.

5. The maintenance shop for "Q" Building Signal Center is
nearly completed. All parts have been stored and location

in the process of being wired-up. The only other item still
necessary for completion is the rack shelving, which should
be delivered during January.

writer School in New York. Four men comp leted an eleven
week course at the on the KW-26.
7. Three men received instruction on the repair and main-
tenance of the Plexowriter. This course lasted one week.
The unit was stripped down and the operation and adjust-
ments were explained. Two weeks is normally the time needed
to complete this course. From the above, it can be-seen
that very little time was expended on the theory of operation
and this instruction does not constitute a thorough knowledge
of these equipments.
8. A Modell was delivered to "I" B ildin Signal Center for
25X1C4a use on the It is being
used as a monitor for additional copies. This was done to
