Africa Number One is still around, although unless you're in Libreville, Gabon, you'll need to listen online. Mind you, the station's audio quality via TuneIn is superb which is more than could be said for the shortwave signal in the 1980's. Believe the studios are now in Paris.
This edition of Media Network discusses the thorny problem of jamming of Western broadcasters. NHK Radio Japan is testing via the new shortwave transmitter site in Moyabi, Gabon. FIBS in the Falklands has switched its frequency of 2380 kHz. (Those bumps on the line with Andy were the counting system that worked out the cost of the call). We reviewed the new book by Ellic Howe called The Black Game. We later returned to the subject in the editions entitled Wartime Deception. Professor John Campbell reports strange broadcasting on 3345 kHz. Sometimes its Radio Mayak. The radio situation is Chad is confusing with at least two stations operating. Radio Bardai is being heard on 2009 kHz. The programme also contains a comparison of the NRD515, ICR70, and the Drake R7A. Michael Schaay has tested all three.
