Radiobroadcasting and Jamming Trends in Eastern Europe and" tho USSR

Introduction

Expansion of radiobroadcasting has enjoyed high priority in postwar Eastern Europe and the USSR, in part because of its valueymbol of improving consumer welfare, but principally because the authorities in these countries regard radio as one of their most effective instruments of propaganda. Radiobroadcasting stations have proliferated rapidly, and now almostillion radio sets are in use. Efforts by Communist authorities to control what is heard on these radios, however, have still notfrom the scene, especially in times ofstress. Thus the occupation ofby Warsaw Pact forces was accompanied by resumption of large-scale jamming of Westernan effort that is still continuing. This report examines current radiobroadcasting trends in Eastern Europe and the USSR, and assesses the recent upsurge of anti-Western jamming.

The table sheds some interesting light on the types of radios produced in Eastern Europe and the USSR, but it would be hazardous to use the sample weights shown toirect distribution of sets in use by type.

9. The supply of solid state components is not yet sufficient to meet consumer demand in Eastern Europe and the USSR, but the number of transistorized radio set models has shown steady growth year by year. Many of the transistorized models are of the "portable" class, but relatively few of the -pocket" types are in factory-scale production. Many pocket-sized transistor radios have been designed andbut most of them have to be builtdo-it-yourself" basis, in general, the pocket radios are designed for one-band operation, but almost all of the transistorized portables are capable of MW and SW reception and manyhird LW band.

High-powered,ammers were used to blanket primarily rural areas, and low-powered local jammers were sot up in and around most of the larger cities to provide urban coverage. Debriefing of emigres and Westernindicated that this effort was successful in blocking out reception in many parts of large cities but much less effective in the rural areas. used consisted of both noise jamming byspecially designed for this purpose and the superimpositlon of disruptive voice and musicon the target frequencies.

Coincident with the occupation ofinhe USSRajor jamming effort against radiobroadcasts targeted at its westorn republics and Eastern Europe. Except for the fact that English-language broadcasts and broadcasts to the Soviet Far East are not jammed, the Soviet jamming effort is not selective; all Western broadcasters are uniformly subject to this harassment, as are their entire program schedules, including music.

Since the springovietOA Russian- and Ukrainian-language broadcasts hasharp upward trend and currently isevel at least equal to the previous peak. VOA broadcasts in Georgian and Armenian are also being heavily jammed Against VOA, the USSR is using what is called Mayak jammingthat is, attempting to override frequencies with superimposed Moscow home service broadcasts. Against Radio Liberty Network, however, Soviot jammers are beaming noise.

14. The aggregate level of jamming against US broadcasts in East European languages is currently much higher than before the occupation of but the situation varies from country to country. Bulgaria, aided by the Soviet Union, has consistentlyigh level of jamming against RFE irrespective ofullby the other Communist countries.

Following the Western pattern, radios with an FM band areincreasingly popular,teadily growing share of radio sets sold consists of transistorized models. The importance of wired loudspeakers is tending to decline in Eastern Europe, but the wired loudspeaker system in the USSR is still undergoing rapid expansion.

The new Communist jamming pattern is not uniform, however, varying according to the country targeted by Western broadcasters, theof the broadcaster, and languages used. At one extreme, Romania and Hungary have not resumed jamming. At the other, Soviet jamming of Russian-and Ukrainian-language broadcasts is now probably at an all-time high. Thus far, however, the USSR has not elected to resume jamming ofbroadcasts, perhaps because they areto be much less sensitive but also possibly because of current limitations on Soviet jamming resources.
