RADIO STATIONS AND THE RADIO INDUSTRY IN YUGOSLAVIA
Numbers in parentheses refer to appended sources]
A. New Radio Stations
1. Radio Yugoslavia
Radio Yugoslavia was established in May 1951 to fill the need for a
radio station exclusively for foreign broadcasting. Up to this time, foreign
broadcasting had been done by the Radio Belgrade short-wave station. Radio
Yugoslavia began broadcasting with a 10-kilowatt short-wave transmitter and a
20-kilowatt medium-wave transmitter. Because of lack of equipment, and because
of the USSR and Satellite campaign against Yugoslavia, most broadcasting was in
Russian and the languages of the Satellites, although some was in Spanish and
Greek. The station broadcast for 10 hours daily.
A new 100-kilowatt short-wave transmitter was installed ana went on
the air on 1 May 1952. At present, Radio Yugoslavia broadcasts 23 hours on
week days and 27 Zs-ic7 hours on Sundays.(1)
2. Radio SiJeme
Radio Sijeme, the newest Yugoslav radio station, went into operation
in Zagreb recently. This is a low-capacity station, which has a range of
approximat 'Y 20,000 square kilometers. Its first programs were musical pro-
grams requested by listeners. Then the Concert Bureau, follcwed by the Munici-
pal Paople's Council, and finally various enterprises availed themselves of the
services of Radio Sljeme.(2)

B. Capacities of Radio Stations
In 1949, Yugoslav radio stations had a total capacity of 452 kilowatts; in
1950, 526.1 kilowatts; and in 1951, 545.1 kilowatts.
In 1951, the number of radio static..s, their capacities and their wave-
lengths were as follows:

G. Radio Industry in 1950 and 1951
In 1950 and 1951, Yugoslav radio technical laboratories produced a four-
channel, short-wave wireless installation which provides for four simultaneous
telephone channels, and a wave analyzer which is equal to any foreign product.
The wave analyzer is made by the "Litostroj" Leavy Machine Factory in
Ljubljana.7
The radio industry also mastered the serial production of magnetic stabi-
lizers; produced prototypes of 3.5-watt and 30-watt dynamic loudspeakers; seri-
ally produced membranes for loudspeakers; serially produced special resistors;
produced capacitors from mica, metal foil, and ceramic materials; produced high-
voltage electrolytic capacitors; and constructed a five-channel wireless instal-
lation for high-frequency telephony.
Television is still in an experimental stage, but plans are being formu-
lated to put in operation the first test transmitter, which will use 625 scanning
lines within a frequency band of 7 megacycles. i
Laboratory research on the construction of a five-channel installation for
high frequency telephony was completed by the end of 1950 with the assistance of
postal, telegraph, and telephone specialists, and a prototype was constructed
which :,atis:iss )resent-day demands of the telephone communications system.
Tests on an installation for high-frequency telephony and transmission of
synchronizing frequencies over high-tension transmission lines have been success-
ful. This installation is vital to the normal functioning of hydroelectric
plants and accurate distribution of electric power. The use of this installation
by power plants will enable them to have private and more reliable contacts,
especially when regular telecommunicatio::s lines are broken.

In 1950, Yugoslavia produced 26,000 radios of the "Kosmaj" model, and
initiated the production of the new "Testa" model. At present, 75 percent of
the parts of the "Tesla" are made in domestic factories, but by the end of 1952
all parts will be produced domestically.(3)
