GB75CH - Celebrating the Birth of British Radar

The 365ft mast at Great Baddow is the last wholly intact example from the Chain Home radar system that was developed by Sir Robert Watson-Watt and his team at Bawdsey Manor following the Daventry Experiment on 26-Feb-1935, and played such a vital role supporting the RAF in 1940

Feb 2010 saw the 75th anniversary of the original experiment at Daventry. Amateur Special Event Stations at Baddow (GB75CH), Daventry(GB75RDF) and Bawdsey(GB75BRS) marked this historic development

On 26-Feb-2010 thru to 28 Feb , GB75CH had a busy time principally on  40 and 80m, plus some contacts on 2m
