ERG was founded on Jan-10 1975. The 70cms repeater GB3ER was first on air on Sept-5 1976 sited at the former Marconi tower on Danbury Ridge. Four years later on Oct-2 1980 it was joined by GB3DA on 2m. Hardware and sites have changed over the years. ERG has a reasonable (though not complete) archive. Some items with historical information are below:-
