AGM report

Thursday 13th January saw the AGM of the Spen Valley Amateur Radio Society, and it was nice to see our full membership turn out on a cold, miserable evening. Not only that, but we were joined by a number of prospective new members.

There were a number of topics discussed after the end of proceedings including prospective talks for the coming year.

As always, some interesting things were passed between members including this tuneable filter that Dave, G4IDR is going to be using to try and reduce the interference and breakthrough he experiences on 2m when operating on EME.


OFCOM announce “Interference” consultation

OFCOM have announced a consulatation document regarding interference to readio users, their summary of which is:

“This document sets out Ofcom’s consultation on draft regulations for new wireless telegraphy legislation, intended to keep pace with technological advances to control interference.
Electrical and electronic apparatus are capable of emitting electromagnetic energy. In most cases, this is minimal and has no noticeable negative effects. However, in some cases the level of energy emitted from apparatus can cause interference to wireless communications.
Ofcom has powers to take enforcement action in instances where some types of electrical or electronic apparatus causes undue interference to wireless communications.
The proposed regulations are intended to be more resilient to technical developments.
The deadline for responses to this consultation is 16 February 2015.”

All radio amateurs are urged to read and respond to the consultation document before the deadline

The document can be found at

Talks Program Q4 2014

We are currently organising the 2014/15 talks program. Generally, we break from having regular talks over the summer months when members are on holiday, so please check back here regularly for the new calendar.

But why not join us on the first and third Thursdays of the month for a noggin and natter night? There is usually all sorts being discussed from Microwave EME through contesting and DX on HF and VHF, Aerials and general electronics. There’s even talk about none radio related things!

Please come and see us soon!

Club Meeting 05 September 2013

Another evening with no fixed format, but at least it was a club night, unlike last week ( when G0TAL & G7DWY turned up !).

We were visited by Richard, G6RFL, and an evening of discussion and debate ensued.

G7DWY brought a 4m low pass filter and directional coupler PCB which he bought for his ongoing amplifier project…


… And a 23cms 2C39 amplifier he has acquired….


Please feel free to come along to the next meeting!

Club Meeting 15/08/2013

This evenings meeting was just pencilled in as a ‘noggin and natter night, but we started with a bit more of a radio theme…..

Stuart, G0TAL has decided to get rid of some of his old radio equipment that is sat gathering dust in the attic, but before being listed on eBay, it needed testing to ensure it worked ok….

To this end Ian, G7DWY brought his Bird Thruline power meter and Doug, G4DZU provided an element to cover the HF bands.

The radio was then tested on transmit into a 50ohm dummy load, and the results were pretty good with the radio delivering its full rated output on the HF bands, but being a little down on VHF – it probably needs a little tuning.

We then connected it to the club aerial and verified reception on the HF bands.

The meeting continued, debating many diverse subjects, not all radio related, but all of interest.

As the meeting was finishing, I turned up the volume control on the club HF rig and had a tune around 17m (18Mhz). One call got a response from Tony VE3AXW in Brantford, near Toronto in Canada. Not bad for a non resonant dipole and 100w!



Time and Frequency Standards – a talk by G4DZU

This evenings meeting has been a talk by Doug, G4DZU about time and frequency standards.
The talk focused on Doug’s quest for a reliable frequency standard, and how this had progressed from his early forays on 2m in the early 1970’s, and the acquisition of different types and accuracies of standards through his amateur radio life, culminating in the current standard locked to an accuracy of 1Hz in 10Ghz – useful for 23cms EME!

Two different ways of getting a frequency standard with differing accuracy

Doug then went on to cover how to lock modern radio equipment to a GPS based frequency standard and the importance of time synchronisation in modern digital modes – very enlightening.

Please feel free to come along to any of our organised talks, and many thanks to Doug for this evenings informative and interactive presentation.

Club Meeting 02-May-2013

Unfortunately Ian G4MLW had to postpone his talk on paperchasing. Hopefully this is to be rescheduled in the near future.

This week we had a number of items for all to inspect, comment on, dissect and generally rip apart.

John, G3TSA brought a SWR power meter from that bastion of radio “Zetagi” which has been rebuilt to be something approaching useable.


Douglas G4DZU brought a directional coupler of a little more professional quality…


Ian G7DWY brought a 4m low pass filter and a selection of kits from W6PQL…


And Stuart, G0TAL brought his sparkling personality!

Come and pay us a visit some time…..
