CARS Meetings January to March 2013 |

28th May 2013 Added the February Meeting photos and report.
The audience in Great Baddow Parish Hall.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: -
Electronic Logging.
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
Murray getting ready with his computer while Carl finishes off his presentation.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 PlanPete Sipple, M0PSX.

March Meeting:-
Friday, 8th March at 7.30pm.
At our New Venue of Great Baddow Parish Hall,
CM2 7DW."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.

Justin, G0KSC then presented a PowerPoint slide show of a range of new Aerials using practical sized materials with innovative designs.

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.
