June Meeting:-
Tuesday, 5th June, 2012 at 7.30pm.
"The World's First Purpose Designed and Built
Wireless Factory - New Street - 1912".
By Mr Peter Turrall, MBE and Mr John Yates, G1UZD.

Mr Peter Turrall, Chairman of the Marconi Veterans Association, will provide an illustrated talk about the history of Marconi and how the World's First Purpose Designed and Built Wireless Factory came to be built in Chelmsford.

In 1908 Marconi closed the Dalston Wireless factory and moved production back to the Hall Steet factory but this was proving to be too small even though a double shift was in place.

Managing Director Godfrey Isaacs decided that the next logical progression was to build a new factory - the foundations were laid in January 1912 (well before the RMS Titanic sunk) and with 500 bricklayers completed it for June 1912.

New Steet - 1912
New Steet in 1912, note the 250ft high wireless masts.

On 22nd June Marconi chartered a special train to bring the 250 delegates from the International Radiotelegraphic Conference in London to Chelmsford, to entertain them and to show them the brand new working factory.

John Yates joined New Steet as a young man and will share his experiences with many of those present who also worked for Marconi - at its peak it employed some 14,000 persons.

If YOU worked for Marconi or have any photographs of New Steet of Marconi, please contact the Chairman or any Committee Member so that they may be copied to project to the interesyt of all those attending.

Tim Wander, G6GUX, new book "Marconi's New Street Works, 1912 - 2012" will be on sale at a special price.   A number of CARS Members and Marconi Veterans feature in it.   A very good read.

CARS will also have its famouis Raffle run by Peter Graves, G0KSJ.

CARS Operated from Stock Windmill, Saturday, 12th and Sunday 13th May.

Many visitors and CARS Members joined us to commemorate the Windmills On The Air.   CARS will be using GB5SM.

The weather was very fine and dried off the watery land.

Stock-GB5SM
Stock Windmill.

Unfortunately a site-visit on Wednesday proved it was nearly underwater and would not support a car let alone Mark’s 5 Ton caravan so we operated from a tent and then only HF.   2m would be from Marks car.

As the caravan will not be on site we will lose toilet facilities.   We will have tea facilities.

The Windmill was open to the public on Sunday from 2 to 5pm - FREE Admission - Staffed by CBC Friends of the Windmill to give you a conducted tour or this Green Energy giant.   Over 100 visitors came to the site - a great turn-out.

Dr Bob Whelan.
Dr Whelan came came from Cambridge and presented a PowerPoint presetation which gave the history of the RSGB from its development from the London Wireless Society and then covered the National Radio Centre at Bletchley Park.   Bob has been a Member of the RSGB for 50 years so has seen a number of changes to the hobby.

Then the meeting was opened to invited questions and to receive CARS ideas about the RSGB.

It was rewarding to see a number of new faces from local Clubs.

A number of books written by Tim Wander, G6GUX "Marconi's New Street Works, 1912 - 2012" were sold at a special price for CARS Members.   A number of CARS Members and Marconi Veterans feature in it.   A very good read.

Please note:- NO cars are to be parked near the Tea Hut - Dr Bowles request.

CARS Special Call-Sign GB100MWT allocated by Ofcom for the year will be used to remind the World that all equipment used in the rescue of the 705 persons was designed and manufactured in Chelmsford.
One must not also forget the large number of Marconi trained Wireless Operators involved directly and indirectly on English, French and German ships as well as the shore stations at Cape Ray, Cape Race and New York.

Colin, G0TRM will have his famous Morse tape transmission equipment in use which some of it is 100 years old.     Youngsters love typing their message and seeing it printed out - they are often given a Certificate.

Sandford Mill is open to the public FREE OF CHARGE from 10am to 5pm with lots to see and for children to play with.

The new book written by Tim Wander, G6GUX "Marconi's New Street Works, 1912 - 2012" will be on sale.   A number of CARS Members and Marconi Veterans feature in it.

Band conditions were generally poor with a Solar Flux of 5 however the nice high aerial coupled with a hill-top site in a quiet location proved that stations were out there.

During a "short" day some 200 QSOs were made.

At 7.30pm Museum Manager Nick opened the invited audience to Oaklands Museum to the launch of the RMS Titanic and New Street Factory Exhibition.

He invited Dr Mike Worboys, Managing Director of BAE Systems, Great Baddow to says a few words.
Dr Worboys said he was pleased to be able to loan the beautiful Marconi Magnetic Detector (MD) to the Exhibition as it was typical of the Receivers used on the RMS Titanic and all the Marconi equiped ships and shore stations involved with the saving of 705 persons 100 years ago.   Marconi Patented the MD in 1902 and it remined in service until after 1918.

Dr Geoff Bowles then told how the Exhibition came to fruition with the great work by Peter Watkins, M0BHY and many other "Monday Workers" including Geoff Lovegrove, G7KLV who built the model DF Set.

Nick then asked Dr Worboys to formally "Open" the Exhibition.

CARS operated from the Foyer of the Oaklands Museum, Chelmsford.
However due to its centre city location the base noise level was quite high so contacts were a little more difficult.
However due to the efforts of Brian Twhaites, G3CVI and Tony Gilbey, G4YTG over 100 contacts were made around Europe.

"RMS Titanic Evening".
By John Bowen, G8DET, Dave Ellis, G4AJY,
Peter Watkins, M0BHY and Andy Tyler, G1GKN.

April Meeting
The CARS QSL card produced by CARS Member,
John Yates, G1UZD.
This evening CARS commemorated the event 100 years ago whereby Marconi designed and built Wireless equipment (in Chelmsford) together with Marconi trained Operators saved 705 lives in mid Atlantic.

It must be remembered that some 10,000 souls were lost at sea between 1800 and 1900 - some of the ships are only just being found.

Marconi Wireless helped end the mystery and saved lives.

The new book written by Tim Wander, G6GUX "Marconi's New Street Works, 1912 - 2012" was on sale at a special price for CARS Members and 20 copies were sold - another batch is on order.   A number of CARS Members and Marconi Veterans feature in it.

CARS had its now famous Raffle run by Peter Graves, G0KSJ and was drawn by Luke.

An packed audience enjoyed the evening thanks to the effort put in by CARS Members.


To start the evening Dave Ellis, G4AJY an Ex Radio Officer was invited read the poem he had written about the RMS Titanic.

CQD SOS!
Jack Phillips at the key.
We’re holed beneath the waterline,
We’re open to the sea.

CQD SOS!
Stars and ice all round,
We’re stopped and sinking by the bow,
No longer New-York bound.

CQD SOS!
Save our souls this night!
A dark, wet, icy grave out there,
God help us in our plight.

CQD SOS!
The band is playing now.
“Abide with me, save me Lord.”
Though He alone knows how.

CQD SOS!
Launch the lifeboats fast.
We’re going down, most will drown,
The Rubicon is passed.

CQD SOS!
Harold Bride is sending.
The Morse key clicks and sparks abound,
For many, life is ending.

CQD SOS!
Forty six thousand tons
Going to the bottom soon,
To be with Davey Jones.

CQD SOS!
The Captain gives the word -
R/O’s must abandon ship.
But neither man concurred.

CQD SOS!
Fifteen hundred dying.
Seven hundred more are saved,
Morse code salvation buying.

CQD SOS!
Jack Phillips dead on station,
But Bride is saved, a hero now,
Before a grateful nation.

CQD SOS!
The tragedy is finished;
A grieving world, shocked and sad,
So many lives extinguished.

CQD SOS!
Good came from that dark day.
Radio’s now compulsory,
Titanic showed the way.
