TUD in 4r VA.L t
SEB/OC-E net with o
in the Building. The purpose of the meeting was to determine T38
requixwm9snts for two-way mobile type VHF equipment.
explained, to the parties present, that the Office of Com-
cunications wishes to standardize on certain types of VHF equipment to
better facilitate support to R88 and 0/C operations.
A discussion of the type operations performed in field use of VHF mobile
equipment, by the Foreign Division, disclosed that it is difficult to ascertain,
in advance, what exact type of equipment would best meet an operational ra-
quirement. it was agreed, however, that in order to best meet a requirement
the equipment should be as flexible as possible.
TSS operational needs for two-way VHF communications equipment can be
categorized as follows:
25X1A9a
25X1A9a
25X1A6a
25X1A9a
a. Vehicular mounted VHF unit, Frequency modulated, in the range of
144 to 179 Mcs. Approximate 25 watt power output. Dash and trunk
type mounts, quick disconnect.
b. Base station unit compatible to the above to operate on 117 VAC 50/60
CPS current with the same approximate output.
c. A walk unit, low power, suitable for concealment
25X1 C
compatible to the above units.
indicated that the General ELectric series 33 mobile units
25X1A9a
would aptly fit ssary when using this unitfon above, However,, a special
50 CPS current otherwise
power supply is necessary .,,r untetl Init. W.

Office of Coeunications.
The problem of obtaining specified drystals for operation in the subject
equipment was brought up. It was agreed that it would be impossible to predict
the crystal frequency needed for a future operation and the necessity of
obtaining proper crystals from manufacturers imposed a certain amount of delay.
The possibility of providing crystals for the equipment through O/C crystal 25X1A9a
grinding facilities was discussed and indicated that
this could be worked out.

 next discussed certain modifications that are made to the 25X1A9a
subjec equiMeaent before operational use. Such things as 25X1 C
fabrication for the insertion of a 'walk-unit' and cabling changes etc. to
mobile equipment were mentioned. felt that as o/c would provide 25X1A9a
equipments rt O/C coul- e necessary modifications to the
equipment. felt that any decision to be made on 25X1 A9a
this subject could not be made by the. - indicated that
or modifications made to the equipment after issue by O/C was their rogaeonrQ5X1 A9a
as they would accept full accountability. Derogattivve'
brought up the desirabilit of distribution to TSS of I4bdifieatioa 5X1 A9a
Work Orders Prepared by OC-g. agreed to be placed on distribution 25X1 A9a
for future W O's as various O/C standardized equipments could filter through
their shop.
at the present time, is preparing an evaluati
f
25X1 A9a
on o
various
VHF mobile and Utility units with the ultimate standardizing of one type in
mind. Results of this evaluation will be forthcoming in the near future.
