John Cooke GM8OTI welcomed participants to the 2014 GM Microwave Round Table

Pete Bates GM4BYF gave some practical demonstrations of simple measurements at microwave frequencies

Andy Sinclair MM0FMF explained the new UK Microwave Group / Summits on the Air award scheme

The UKuG / SOTA award scheme has a snazzy new certificate

A session on personal microwave beacons was started by Alan Dimmick GM0USI

Followed by Brian Flynn GM8BJF who talked about a special beacon GM3WOJ/B

GM3WOJ/B is designed to scatter its signal off the Cairngorm mountains, so that it can be received further south


An extra short item before lunch was presented by Ed Murphy GM3SBC who has a new software defined radio design almost completed

Participants assembling for the afternoon session


The afternoon session was chaired by Andy Sinclair MM0FMF, President of Lothians Radio Society

David Anderson GM6BIG opened the afternoon session with a talk on "The History, Development and Future of GB3CSB"

David's talk was a fascinating account of the GB3CSB beacon cluster, with lots of technical content

The final talk of the day was from Graham Murchie G4FSG, RSGB Chairman, who spoke on "The RSGB and Microwaves"

Some interesting discussions followed!
