It is difficult to imagine a subject with more elusive data than this. The source and location of clandestine radio broadcasts are, by definition, secret. `White' stations openly identify themselves (such as Radio Free Europe), and `gray' stations are purportedly operated by dissident groups within a country, although actually they might be located in another nation; but `black' stations transmit broadcasts by one side disguised as broadcasts by another. . . . [This] is an extraordinary book. It belongs in every research library concerned with war and revolution and international communications. A valuable appendix lists known clandestine radio stateions, 1948-1985.
