A very technical edition of the programme. After announcing some frequency changes, we look at the possible use of single sideband (SSB) for shortwave broadcasters. in theory, 2015 should have been the point at which AM could be switched off. In the end that's probably true, except that it wasn't replaced by SSB. This was before anyone saw the opportunities of the Internet. Trevor Brook of Radio Fax was completely sceptical. Peter Senger of DW was also realistic. It was all about the availablity of receiving equipment. We did an indepth on-air review of the Drake R8, and spoke with John Bryant, one the authors of Proceedings 91. This was an excellent collection of indepth technical articles. A great read if you can find a copy!
