This week, Geoff G3TPQ, takes us through receiver technology from the first part of the 20th Century – perhaps the most important and progressive period of radio history to date. He’ll cover early spark based communications, and the first steps in electronics. Geoff will then look at the receiver technology available at the time, such as crystal sets and the various methods of amplification used in early 1920’s wireless sets. Geoff will also show us early horn type loudspeakers which allowed several people to listen to the “wireless” at the same time.
So, if you enjoy technology history, why not join us for a look back at this fascinating era when “wireless” became “radio”.
Club opens at 7:00 pm, with the talk starting at 8:00.
Members and all visitors welcome.
