ABSTRACT
The International Telecommunications Regulation exists to coordinate and facilitate international telecommunications. When member states undertake actions which hinder international communication, they do more than merely violate the Radio Regulations. Listening to international broadcasts is a violation of domestic legislation in Albania and North Korea, among several other countries. In South Korea mere possession of a shortwave radio receiver capable of receiving international broadcasts is strictly illegal. Deliberate interference of international telecommunications entails far more than merely the jamming of radio broadcasts. It is jamming, however, which is the most conspicuous manifestation of deliberate interference, and the only one which is at least potentially controllable through international collaboration and regulation. Technical innovations reducing the level of adjacent channel interference have been more than offset by this general increase in the number of high frequency (HF) directly jammed. Jamming has a serious and adverse impact on all parts of the HF broadcast spectrum.
