Previous Diary Items:

  Wed 8 Jun 2022 - A talk with many 'physical examples' for the 'audience' to indentify the wiring and/or assembly fault(s) under the, lose, heading of Terminations. Perhaps the title should have been Electrical Mis-Terminations as there were many examples of why 'some people' should not be allowed to work on connections using mains electricity. The demo was quite 'entertaining' but, mostly, very instructional and educational.

-----------------------------------------------------------------------

  Wed 11 May 2022 - A practical demonstration by Mike (G0IBZ) of overhauling and re-assembling a four-section pneumatic (Pump-Up) Clark Mast and hand-operated pump. The demonstration also included useful tips & tricks when overhauling, replacing and rebuilding the mast. To conclude the demonstration, the mast was assembled in the Car Park and pumped-up: Yes, it worked perfectly.

-----------------------------------------------------------------------

  Wed 13 Apr 2022 A talk by Sean (2E0RXI) showing the construction of the 2m 'Flowerpot' Antenna with instructional and practical help. The aerial is based on the VK2ZOI Design.

  Wed 9 Mar 2022 - A talk by Iain (G0OZS), our local RSGB District Representative (DR125), on Electromagnetic Fields (EMF) and the requirements for the active Radio Amateur. The talk has up-to-date information and uses the 'better tools' that are now available and includes Ofcom and RSGB Calculator screen-shots to assist every active Radio Amateur to conform to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) requirements.

-----------------------------------------------------------------------

  Wed 9 Feb 2022 - Short Extraordinary General Meeting (EGM) to accept a new SAnDRA Constitution and elect a Committee until the next AGM, planned for 12 October 2022. For the Constitution click SAnDRA Constitution 2022.

The EGM was followed by a talk entitled Antenna Radiation Patterns given by Neville (G8CDG). The talk gave us some very useful in-sight into some aerial radiation patterns, 'exploded' a few myths and raised several points that need to be considered when installing aerials.

-----------------------------------------------------------------------

  Wed 12 Jan 2022 - Cancelled - Sorry 'folks' but this meeting had to cancelled due to various effects of COVID-19: Sorry as I know several folks were looking forward to the talk but it will be re-scheduled ASAP. 

---------------------------------------------------------

  Wed 8 Dec 2021 - SAnDRA Christmas 'bash' organised by Mike (G0IBZ).

The SAnDRA 2021Christmas Party was held on Wednesday 8th December 2021 in the Back Hall of Wells Hall Old School (WHOS), CO10 0HN at 20:00 hrs and was a self-catering event and was enjoyed by all those at the meeting.

Many thanks Mike (G0IBZ) for organising the evening.

-----------------------------------------------------------------------

  Wed 10 Nov 2021 - Talk on the GDT and EMC.

What was originally planned to be a talks on Electrical Safety, the Gas Discharge Tube (GDT) and Electro-Magnetic Compatibility (EMC) was, due to the several queries received before the meeting, changed to the GDT and EMC.

The GDT. Trying to protect aerials and cable from a direct lightning strike is totally impractical for most - if not all - Radio Amateurs. However, disconnecting the Aerials and including GDT's, with a resistor across the GDT, will give a fair degree of protection from statically-charged rain and very minor lightning discharges.

EMC. This is a colossal subject but understanding a few 'basics' of how the energy (interference) is transferred, locating the source, detecting the cause and knowing some possible solutions should help. During the meeting, there was good 'Audience Participation' and afterwards the feedback was positive.

As several Radio Amateurs currently experience fairly high levels of QRM & QRN, this was considered to be 'EMC Part 1' as there will probably be updates from others as they carry out there own investigations and fixes. In the meantime, a short 'overview' of the talk is planned to be added to this website. Please 'watch this space'.

Both talks were given by Tony (G8LTY).

  Wed 13 Oct 2021 Sudbury And District Radio Amateurs (SAnDRA) held their first meeting since the COVID-19 restriction were imposed about 18 months previously. The meeting was well attended, with several 'new faces' who had not previously attended our club, and enjoyed by all. It was really great to be able to 'physically' meet again.
