/ SUBJECT:

SEBASTIAN JOHN LA ROCCA, aka

AR

(00: PITTSBURGH)

In the above-captioned case Pittsburgh has conducted a MISUR

survey and submitted FD-142 requesting authority to install a MUTT

transmitter in subject's office.

The Laboratory has studied the survey results and concludes

that the environment, from an electrical standpoint, into which it is

proposed that the installation be made is generally unsuited for a

radio transmitter installation. The concealed equipment and antenna

must be placed directly under a corrugated sheet steel roof. Electrical

machinery in the adjoining elevator building, banks of high tension

transformers adjacent to the point of installation, the transmission

distance along with the high industrial area noise are all considered

to be disruptive elements insofar as obtaining successful transmissions

from this area is concerned. However, due to the importance of this

particular subject, the Laboratory suggests that an installation attempt

be made in spite of the adverse electrical conditions surrounding the

area." In the event the environment precludes successful transmissions

out to a monitoring point, then the equipment would have to be removed

and the plant discontinued. In the event the installation can be made to

function adequately, then, of course, it will be continued by the

Pittsburgh Office.

REG- 4

92-2940-64

•If the Investigative Division agrees that an attempt should be

made under these conditions to establish the MISUR recommended by

Pittsburgh, the Laboratory suggests that an engineer of the Electronics

Section proceed to Pittsburgh in order to supervise the installation.

RECOMMENDATION:

T8, JAN 301961

That the Laboratory's evaluation of the Pittsbursh Survey in this

case be forwarded to the attention of the Investigative Division.
