The first P:7 indicated that there was a transmitting and receiving sta-
tion on the southern edge of Petrozavodsk (61?491 N/314?20' E), Karelo-
Finnish S.S.R., on a high hill, just east of the river which flows through
the town. This station consisted of an old installation and a new one.
According to a German from the Baltic States, a radio technician, who
worked as a foreman in a Soviet construction detail dispatched by a Moscow
enterprise, the old installation relayed and amplifiediroadcasts from
Moscow. The transmissions, presumably made Lb radiotelephony, were beamed
to the Petrozavodsk area. the area covered by the
radio station was to be enlarged to include the Scandinavian countries since,
according to the German radio technician, the output of the transmitt

been increased four times. (1)
2, The old antenna system had four wooden masts, each 30 meters high, set up in
two groups, one off each side of the radio station. Each mast was 50 meters
from the other mast in its group and interconnected with it by two wires.
Each of the groups of two masts was connected with the radio station by an
overhead line. Parallel to this system was a second antenna system of
eight wooden mastsyeach 4 meters high. This system was also divided into
two sections, the distance between masts in each section being 10 meters.
The second antenna system was connected with the radio station by underground
cables. (2)
3. The new installation was a radio tower whose construction begs ri in October
l94 , and was to be completed by January 19119. The work was done by a
special Soviet radio construction detail. In January 1949 this tower was
40 meters high, but, according to a Soviet radio technician, it was even-
tually to be 240 meters. It was a steel framework, which did not taper at the

The sides of the angle irons each measured 15 cm and were 14 mm thick.
The lower part of the tower was covered with steel plates and rested on
eight foundations, 2 meters square and meters.deep. The tower was
braced by 12 to 15 cables. (2) One hundred and twenty copper wires, each
150 meters long, were laid out in the form of a star around the radio tower,
20 cm underground.
The Soviet radio technician said that the old radio station operated on
long, medium and short waves and that its output had been increased four
times. Source thought it-possible that the new radio installation was an
ultra short-wave transmitter. (3)
The power transmission line, supported by masts 13 meters high, led to the
transformer station. One transformer station had been set up in January
1949, and two more were scheduled to be erected. A small, 1,000-volt
motor of German origin was housed in a wooden annex to the old radio station.
This motor was probably a transformer. (4) In early 1949 the radio station
was connected with the transformer station by a Siemens lead cable, 200 meters
long. The cable ditch was 70 cm deep.

office and was occupied by about nine men.
A mobile radio station consisting of four Pullman[ coaches of 54 tons each
was standing on a siding, at the nort east edge of the town near Lake Onega
and near Leningrad Street. This radio station had a steel mast, tapering
toward the top and 50 to 60 meters high. The noise of running power units
was heard from one of the coaches. (5)
Z. The second PAY reported that the transmitter of the Radio Komitee (sic), a red
brick structure resembling a church, was at the intersection of Lenin Street
and'Kirov Street. (6) A cable ditch, 70 cm deep, led from there to the
"Radio Stantsia" (sic). The cable was 3 to 4 cm thick,
Thet"Radio Stantsia" was on a hill south of the railroad bridge over the river.
It was a flat stone structure with a steel mast 30 meters high. The construc-
tion of another mast, 120 meters high, was begun about February 1949. In
addition, a three-story dwelling was being built. About 130 insulated copper
wires, 5 mm thick and about 100 meters long, had been laid out 30 cm under-
ground. They radiated from the foundation of thw new radio tower under con-
struction. At night the radio station was marked by red lights.

leading into Lake Onega and the shipyard to the southeast. The machinery
connected with this station was housed in railroad cars, parked on a siding.

fitted on the roof of the coach, was -DO meters high. Four wires led to the
top of the steel mast which had a loop antenna. The machinery in car 2 was
a 150 to 200-kw installation. According to other PWs who were trained radio
The third PW reported that a mobile radio station housed in railroad cars was
on the shore of Lake Onega between the mouth of the river and the Old Port,
about 350 meters east of the small power plant. It consisted of three rail-
road coaches. The first coach had the antenna system, coach 2 had the machi-

(1) its s obviously a broadcasting station, a subsidiary station of Radio
Moscow. No details are available on its output and frequencies.
(2) See Annex 1 for source's layout sketch of the transmitting and receiving
station. Also in this Annex are sk etches of the radio tower.
(3) The new installations cannot possibly be an ultra short-wave transmitter.
Probably it is a modern-type radio mast working without antenna.
(4) The motor probably was a transformer for the generation of 1,000 volts.
(5) The mobile radio station probably is a reserve transmitter with short-wave
directional effect.

stations.
