An informal group of former employees of Marconi. Most members worked for what used to be Marconi Radar Systems and live around Chelmsford, Essex but this is not an exclusive criterion. The main social activity is a weekly get-together on Fridays in the Orange Tree public house in Lower Anchor Street, Chelmsford, plus an annual Christmas dinner. The group organises occasional walks and visits to places of interest. There is an active sub-group of golfers.
