14 Oct 2021 – Contests, Past and Future?

Don, G4LOO began by showing statistics from our CQ-WW SSB entry from 26-27 Oct 2019, followed by several photos of the site set up.

The 2019 ‘RUN’ Beam

That year we did experience several equipment problems which were reflected in the score. However, we did manage to be fourth in our class in England out of 8 entries.  Don showed the statistics covering bands worked and results achieved hour by hour during the entire contest.

Of course, 2020 reflected the operating restrictions due to the Covid Pandemic lockdown. Only two operators took part working one at a time. Their score in Europe was 57 out of 88 stations in their class. However, in England, they achieved First place in their class!

Don then explained the equipment to be used this year and how the stations would be set up and run. The aerials will be about the same as 2019 with an eye on the pitfalls experienced in 2019.


7 Oct 2021 – RSGB’s EMF Calculator

Members watched a video by the RSGB on filling out the latest EMF calculator.  Quoting from their web page: “The New Amateur Licence now requires all amateurs to check compliance with EMF exposure limits. Compliance is required after 18 November 2021 for frequencies above 110MHz, after 18 May 2022 for frequencies above 10MHz but below 110MHz, after 18 November 2022 for frequencies below 10MHz”.

As presented, the calculator only shows results for frequencies above 10MHz, the lower frequencies will be covered in a later publication.

Discussions followed the video, including some speculations about what will befall the lower frequencies.  The calculator can be found at      Look for RSGB/Ofcom calculator (3.6 MB MS-Excel Worksheet version rsgb11a) V0.1.2

Silent Key, Don Perry, G7FZE

Don was a quiet man who was an active member of our society. He lived in Luton all his life except for his time doing National Service in 1956. After that, Don returned to George Kent Ltd where he had originally done his apprenticeship in 1951. He worked for the company for 23 years till retirement.  Don was licensed in 1989 but had been a club member since 1975.

After an accident, Don passed away on 2 October, 2021. He will always be remembered and greatly missed.

Second Club Meeting – 16 Sept 2021

On the 16th of September we held our second ‘proper’ meeting; 13 members attended. The chairs were arranged in our usual format, which helped.

The topic for discussion was Telescopic Fibreglass Masts and some issues  with their use.

David explained how if affected by wind they can slip and retract a little.  This can be overcome by using jubilee clips. However, this in itself can cause problems as the metal can damage the mast.

The use of plastic tubing, as used in fish tanks, folded over the clip greatly reduces the hard pressure. The clips are located where the sections of mast are located.  This will prevent the mast slipping down and making the guys slack, which will stop the mast being damaged in high winds.

A selection ‘U’ bolts was demonstrated to enable fibreglass masts to be clamped to polls or other securing devices. These clamps come pre coated with hard rubber to prevent damage to the mast.

This short talk lead to some debate about where these clamps could be purchase and some of the problems others had had with their masts.

Club Meetings to Restart – 9 Sept 2021

On the 9th of September 2021 we had the first meeting back after the pandemic lockdown. The number of members who could attend was limited by the Hall’s Covid rules and the setting out of chairs was not our usual system. That seemed to hinder general discussions, but those who attended were pleased to meet again.

David would appreciate some feedback from members on the first club meeting since March 2020.  )

Just a reminder that if you intend to visit the club on Thursday evening please let me know. Numbers are limited to 25 and I need a list to conform to the Community Halls Covid risk assessment.  (

A Special Notice from the Committee – 18 June 2021

We have over the past few months seen different options provided by the government on when things get back to some form of normality.

Various options have been looked at, only to be dashed by new strains of the covid virus.

For this reason we are now looking at returning to the Community Hall (Club House) after what would be our normal summer break.

The most probable date will be 9 September, where hopefully things will have some semblance of normality for us all.

As you can imagine we do not have a full programme as yet as we have not been in a position to organise any activities, having said that I am sure many of you have kept yourselves busy in one way or another.

I am sure that there have been things you have built or contacts you have made that will interest us all and this will be a chance for you to let us all know what you have been up to.

Some members have already volunteered to give a talk, which will start the programme off.

There will be a Committee meeting to set out our plans to move forward and bring the club back to normality.

Keep an eye on our website or emails for information.

Hopefully by September we will be in a safe environment, however if things change we will have to make some adjustments.

Stay safe and well.

Dealing with your Lelantos measurement —–7 Nov. 2020

Well, the first thing is to have a good look at the results using Lelantos to show the graphs.  Of course, if you believe you are being troubled by VDSL QRM you will already know that, but this may prove the source. If you’re still unclear about the situation, read:

The next step is to report the interference to Ofcom:

This may seem a daunting task, but in essence it’s really a statement of facts. You may be asked to keep a log of the stations you cannot hear due to QRM from VDSL (!)  This may be accomplished by comparing what you hear to that of a nearby online SDR or comparisons with another nearby radio amateur. The QRM will not be dealt with if only a few radio amateurs report it.

It has been known that Ofcom do not always provide a usable answer to the problem, so what to do?  Take it a step further.
