Roger Tidy has been interested in the use of international radio as an instrument of propaganda all his adult life. He has worked for many years in the broadcast-monitoring business and has contributed, as a freelance writer and reporter, to numerous publications and radio programs in the UK and abroad. In the 1980s, during the Cold War, he published a weekly newsletter for radio enthusiasts, charting the latest developments in the ongoing struggle of the airwaves between Western, Eastern, and "non-aligned" ideologies.
