For a more detailed look at security problems and intelligence activities at Radio Free Europe and Radio Liberty, my book Cold War Radio: The Dangerous History of American Broadcasting in Europe, 1950-1989 is available for order on Amazon, Barnes & Noble, etc.
Description from the publisher, McFarland: "During the Cold War, Radio Free Europe and Radio Liberty broadcast uncensored news and commentary to people living in communist nations. As critical elements of the CIA’s early covert activities against communist regimes in Eastern Europe, the Munich-based stations drew a large audience despite efforts to jam the broadcasts and ban citizens from listening to them. This history of the stations in the Cold War era reveals the perils their staff faced from the Soviet Union, Bulgaria, Romania and other communist states. It recounts in detail the murder of writer Georgi Markov, the 1981 bombing of the stations by "Carlos the Jackal," infiltration by KGB agent Oleg Tumanov and other events. Appendices include security reports, letters between Carlos the Jackal and German terrorist Johannes Weinrich and other documents, many of which have never been published."
Reviews:
"Cold War Radio is well documented and leaves no doubt about the value of the radios to the citizens of communist nations to which it broadcast. It also makes clear that for the broadcasters and the management, the Cold War was anything but cold. This is a valuable contribution to the literature." Hayden B. Peake, The Intelligence Officers Bookshelf, Studies in Intelligence Vol. 54. No. 2 (Jun. 2010).
"The Director of Security Radio Liberty for 15 years from 1980 onwards. Cummings’ experience as a Russian linguist serving in the US Air Force in Berlin in the 1960s places him in the perfect position to supply this examination. For anyone with even the slightest interest in the machinery of the Cold War, it’s safe to say that "Cold War Radio" deserves your attention"--Historytimes.com
"The book is an excellent resource for future Cold War histories,". James Critchlow, Journal of Cold War Studies, Vol. 12, No. 3, 2010
"A shortwave radio thriller...takes readers deep inside a world that their casual listening to these shortwave stations would never have revealed"--Radio Heritage Foundation.
"I heartily reccomend this book to clandestine radio fans and anyone who's fascinated with the secret side of international broadcasting." Gerry Dexter, Popular Communications, November 2010.
