Harry Heap, G5HF passed away on 27 August 2012 at a nursing home in Chelmsford, aged 95. He was the very active President of the Chelmsford Amateur Radio Society from October 2000 until October 2010.
He was first Licenced as 2BZZ in 1932 at the age of 16 and was issued the call sign G5HF in 1933.
He joined the RSGB in 1938. Harry was especially interested in the then new 56MHz band.
Following the outbreak of World War II he moved to Chelmsford to join Crompton Parkinson, where he worked on devices to neutralise magnetic mines. The evenings he spent as a Voluntary Radio Interceptor. Harry was a great lifelong friend and colleague of Louis Varney, G5RV, famous worldwide for his aerial design. Both Harry and Louis were part of the very elite group of secret listeners providing received ‘off-air’ coded material to ‘Box 25’, which we now know was Arkley View near Barnett where it was vetted before being passed to Bletchley Park. Their names are on the Roll of Honour at the site. Harry regularly attended the reunions of the Box 25 RSS group to keep in touch with those still surviving.

Firstly there was a vote as to whether CARS Meeting should stay in Great Baddow Parish Hall for 2013 and meet on the only night thought to be available, namely Fridays. 5 persons showed that Friday was not ideal while over 35 showed they were happy with the suggestion. Brian, G3CVI will try and secure a booking for 2013 with a request to see if another night is available for 2014.

John said that the Meeting was a Tribute to CARS Past President, Harry Heap, G5HF who died in August 2012 aged 95 years. Contributions were acknowledged from Harry’s Son, Peter Heap and from Ethel Chinnery; Tony Gibley G4YTG; Trevor M5AKA; Dr Brian Styles G3NSD; Bob King G3ASE; Colin Page G0TRM; Gwyn Williams G4FKH; Carl Thomson G3PEM; Tony Manson and Peter Foreman both from the Chelmsford Engineering Society. Vice Presidents Geoff Mills G3EDM and Charles Shelton G0GJS, also contributed. His daughter Celia and husband Brian were also present as was Sylvia, YL of Geoff G3EDM and Margaret, widow of Geoff G2AMQ SK who featured on later in Falcon.
Tony told the audience of the life story of Harry up to the creation of CARS with Louis Varney G5RV and Mr Fuller G6LB. At appropriate points Colin played tapes of Harry telling "how he was interviewed by the Chief Constable of Manchester before being enrolled as a Volunteer Interceptor (VI).
Arkley View was PO Box 25 Barnett where the 1,500 VIs sent their data to be vetted before being
passed to Bletchley Park for Decryption.

Harry then described how "later he had to join the Home Guard and guard their rundown headquarters in Chelmsford with a rifle but no ammunition – this was to be obtained when needed by cycling to the Brigadier’s house where 3 rounds were held."
John read out a tribute by Dr Stephen Castell “who in 1973 had joined RHP as a Senior Mathematician and Harry assisted him with telling him Chelmsford past illustrious engineering history, its then current scene, and the quirks/nuances of those people and companies in it”. He said “He was a solid professional, thoroughly nice guy – altogether a fine human”.
Harry was at this time President of the Chelmsford Engineering Society.
Andy Tyler, G1GKN managed to get the computer to show slides of Harry’s early life, followed by a selection of the 28 foot sailing boat, Falcon with Gwyn crewing and explained each photograph. Harry sailed to Belgian, France and Holland. On one occasion Harry spotted a dinghy overturn and with great skill manoeuvred his boat so that 2 men could be rescued – the dinghy sinking - never to be seen again.

Tony Manson (CES) told how “Harry had a number of Riley racing cars which were raced at Silverstone, Boreham and at Prescott Hill Climb near Cheltenham. The tasks of rebuilding the car after racing was helped by Pippa, Harry’s Wife who was a trained Engine Fitter. Harry even encouraged me to race in his car”.

A good number of Raffle prizes were organised by Carl and James 2E1GUA and drawn by Luke.
Thanks to the Bar Tender for attending to the thirsts of those there. Thanks to Dave Bolwell ex G3JCM for setting out the projector and solving many of the troubles encountered at the start of the evening – was Harry’s ghost involved?

Chairman John G8DET starting off the Meeting with a few announcements and then introduce President Carl, G3PEM for the first of the evening’s two talks: -
Carl G3PEM explained to Members that CARS will be taking part in operations to celebrate the Centenary of the RSGB and CARS will be operating G100RSGB on the 21st and 22nd of July. To support the RSGB challenge, all clubs are required to supply electronic logs in ADIF format each day of operation.
Carl has been using computer logging since 1998. He pointed out that with over 50 logging packages out there, everyone thinks the one they use I’d best. CARS has decided to use Logger32 for the RSGB event.
To help members new to Logger32, Carl then walked through the process of entering details of a QSO and adding it to the computer’s electronic log. Carl also talked briefly about the World map for Greyline Propagation, the RTTY interface, and the Gridsquare Calculator.
Logger32 is a powerful application, but to keep operations simple, only the basic logging features will be used. Based on our experiences of Logger32, it comes into it’s own when connected to a radio, as the application can control the rig. For the RSGB event, CARS will be keeping it simple and running the program as a stand-alone logger.
Carl’s demonstration was well received, and gave an excellent introduction to electronic logging. If you want to try Logger32, it’s a free download from www.logger32.net

New Bands and New Band Plans
Murray G6JYB gave a very informative presentation on the 2013 RSGB Band Plan. Murray is well-placed to update members as he is the RSGB Band Plan Editor.
The presentation kicked off with the display of a scan of the 1969 band plan.
Far less than we have now, 2 metres was a secondary allocation, and not a lot of digital modes.
Next, Murray outlined various changes in recent years, and offered information on how the plans are put together and reviewed. Then, on to the new changes:
Murray, G6JYB anf (right) Luke (Raffle Caller) and Raffle associate, James 2E1GUA.
2m data section changed, and changes to DStar Simplex.
A possible move for the 2m WSPR frequency may happen in April 2013 to avoid interference.
Spectrum release: We’re losing 2.3 and 3.4GHz, which is an issue for ATV.
472kHz became available to Full License holders from 1st January. A NoV is required.
5MHz band also became available from 1st of January (Full licence with NoV) – see TARG “Getting started on 5MHz.” The allocation is a tricky one, requires care, and may require you to modify your radio. A show of hands showed 3 or 4 members have used 5MHz.
Wrapping up – a look at what’s next.
Expect changes to the 70ms band plan (to include colour DATV and the 70cms beacon project)
Possibly more VHF coming our way… 70.0-70.5MHz, 80-81MHz and 146-148MHz. Cross your fingers!
One of the key messages is to make sure that you’re not operating using an old or unmaintained band plan… Murray said there are a lot of them about. The current band plan is on the RSGB Web Site - see RSGB Band Plan
Pete Sipple, M0PSX.

As we have said before "You heard it at CARS First".
Tony, G4YTG brought along a table full of books from Harry, G5HF SK while Colin, G0TRM brought along a number of
SK rigs and equipment - the proceeds going to the Essex Air Ambulance.
CARS also had its now famous Raffle run by Carl, G3PEM and James, 2E1GUA.
A good evening was had in our New Venue. See Venue photos below.

At our New Venue of Great Baddow Parish Hall,
"Commercial Aerials for the Radio Amateur"
by CARS Members, Justin Johnson, G0KSC,
Peter Waters, G3OJV and Norman Crampton, M0FZW.
Chairman John, G8DET welcomed CARS Members and visitors and highlighted Terry Woodcraft, who took the RAE 18 years ago and with the assistance of James, 2E1GUA just obtained Call-sign M0HHQ.
At the September 2012, CARS Meeting in MASC pictures were shown and descriptions given of Practical Aerials as used by CARS Members.
This generated sufficient interest to have another Aerial Meeting but this time talking about Commercial Aerials manufacturered for the Radio Amateur instead of the many "long" wire Aerial discussed previously.
Quote from CARS Aerial expert, Tony, G4YTG "Aerials are a bit like Ladies Hats - they all have bit sprouting from them - which blow off in a high wind". The more usual quote from the USA is "If it does not blow down in Winter the Aerial was not big enough or high enough!"
John Yates, G1UDZ started the evening off by describing his Aerials attached to his house in the UK and to the family log cabin in Finland.

Mark Sanderson, M0IEO then showed the CARS Comet 250B 21foot high Vertical Aerial which was described as being a large resistance, a few Ferrite Coils but it did radiate well in a restricted location.
Justin, G0KSC then presented a PowerPoint slide show of a range of new Aerials using practical sized materials with innovative designs.

This brought us up to the break time where Peter Waters of Waters and Stanton manned a table full of Radio Amateur maps, MFJ catalogues and Log Books - all avaliable for CARS Members.
The Raffle was announced by Norman as Luke was not able to attend.
Andy Kersey, G0IBN presented Morse Certificates to a number of his Morse Class members including Robin, G7VKQ from Greenwich, London.

Peter Waters then stood on the stage and said how he came to begin the now famous Hockley firm from his involvement with American Aerials.
He said that they were the suppliers of many Aerials mainly because they were the UK Representives of so many manufacturers. The G5RV still sold well.
