Following on David’s talk, Terry Giles G4CDY will be giving his re-created Aerial Circus presentation that was originally given by Dud Charman G6CJ  This will be from about 12:00. Announcements will be made on the day when it is up and running.

Terry G4CDY is now the Secretary of CATS and he gave this presentation to them back in 2013 – see their Nov 2013 Newsletter  

The photo shows Terry  using a piece of copper PCB as an artificial “ionosphere” to show how QSB (fading) can be caused by the interference of two or more waves arriving at the receiver via different routes of continuously varying path length.
