It is with regret that we have to report that CARS Vice President Geoff Mills, G3EDM, passed away on 16th December, 2014. CARS sends his Family our Sympathy.

Tuesday 6th January 2015, 11.30am at Saint Mary the Virgin, Church Road, Little Baddow, Chelmsford CM3 4BE. Access to the Church is via single file road and there is little parking so lift sharing is advised!

The Generals Arms,The Ridge,Little Baddow, Chelmsford CM3 4SX. Please inform Bakers Funeral services if attending (01245-221100 or )

The family has already been overwhelmed and request no more cards/flowers. The Family wish is that any Donations are to Saint Mary the Virgin Church.

It is with great sadness that we have learnt of the passing of Geoff G3EDM. I first worked Geoff on the 10th May 1969 on top band AM when his QTH was Billericay. I always found Geoff a fountain of knowledge when you had a problem and the advice was freely given. He was a gentleman of the old school, very well respected both in the amateur radio field and by all those students that knew him from Mid Essex Technical College.

I will miss his advice, support and guidance that he has given to me on technical issues over the years and we will all miss the time he devoted to the Chelmsford Amateur Radio Society.

Our sincere condolence's to Sylvia and family

It is very sad indeed to hear of the passing of Geoff who was such a stalwart of Amateur Radio and of the Chelmsford Amateur Radio Society. Our sincere condolences go out to all his family and friends all over the world. In an amateur world he was a true professional and his knowledge and skills were respected by everyone. He will be sorely missed.

Geoff joined the Post Office Telephones in London Headquarters during the 1950s and worked on the development of the Type 2 Register Translator used to switch trunk telephone calls automatically eg without the involvement of a Manual Operator later called Subscriber Trunk Dialling (STD).

The Type 2 R/T Laboratories were based in Wood Street, London (near St Pauls) but Geoff did get involved with Tommy Flowers in Dollis Hill. Tommy is now known as the developer of the Colossus at Bletchley Park the Type 2 R/T uses similar techniques but Geoff said he knew nothing of the Bletchley Park involvement.

The Type 2 R/T was installed in Bristol Central Telephone exchange and Geoff made a number of visits there culminating with the Queen making the first official STD Call to the Lord Provost of Scotland in Edinburgh in 1958.

Geoff left the GPO in the 1960s and joined the Technical College, Chelmsford retiring in 1982. He was heavily involved with the Open University from its inception in 1969 to 1995.
