At the meeting on 24th April 2019 Terry Martini-Yates of Ferrograph World, based in Rosyth, talked about "Writing in Iron" - magnetic sound recording - demonstrating several recorders and playing a number of historical recordings, including John Clarricoats G6CL during a visit to Edinburgh in 1961.
Terry writes: "A potted history of the development of the magnetic audio recorder from Valdemar Poulson’s invention of the magnetic wire recorder, the steel tape based Blattenerphone, its further development at AEG in Germany and its use by the 3rd Reich in Nazi Germany for war propaganda, to the overnight sensation it created in post-war America, when an enterprising soldier liberated two of the secret German Magnetophon reel to reel tape machines and 50 reels of recording tape.
Terry is the author of 'Built Like a Battleship!, A History of the Ferrograph Company'.

In his second talk, Brian showed how to receive the recently-launched AMSAT Es'hail-2 geostationary satellite. He has been receiving the 10 GHz transponder output at his QTH in Peebles and has established that it can be done with quite simple gear. As it is planned to be operational for 20 years in its geostationary orbit it could have quite an influence on amateur radio and be readily accessible.
Rx set-up: 60cm Sat TV dish, PLL LNB & SDR dongle.
