Expansion of North Vietnam's International Undiobroadcasting Effort


Sincenternational radiobroadcasts controlled by Hanoi have climbed fromours per week to moreours. Radio Hanoi and Radio Liberation (the clandestine voice of the Viet Cong) have accountod for most of this expansion, with smaller increases in the clandestine broadcasts known as Radio Pathet Lao and Radio of the Patriotic Neutralist Forces

The primary target audiences for Hanoi's official and clandestine international broadcasting are the indigenous populations of South Vietnam and Laos. Allied forces in South Vietnam also have begun to receive substantially increased attention, and since the beginning of the Paris talks, Hanoi has initiated radiobroadcasting to the European area. Transmissions to Europe now amount to almostours per week.

Tho clandestine broadcasts of Radio Liberation, Radio Pathet Lao, and Neutralist Forces Radio are not independent operations originating from South Vietnam and Laos, aa represented by North Vietnam and other Communist countries. From all indications, these clandestine broadcasting operations are tightly controlled by North Vietnam and probably are carried out from the Radio Hanoi transmitting complex located at Me Tri.

North Vietnam has achieved this rapid expansion in international programing by importing seven now

Hanoi is procuring more broadcasting equipment from both Communist and Free World countries, and it can be expected that the North Vietnamese radioeffort will be further stepped up.
