A defibrillator first aid course has been arranged four our next meeting at the Community Centre in Cwmnduad.

The date is 23.2.16 a Tuesday from 7 pm to 9 pm. This is an extra date in addition to our normal club meets.

There will be a break for refreshments at 8 pm.


A member of the ambulance service will be available to give practical Instruction on resuscitation and the use of a defibrillator of which there are many situated in public areas.

The course is very much hands on with the emphasis on saving life.

This really is a life skill you should have !!!! I am sure you will want to invite a neighbour !!

As radio enthusiasts building our own equipment etc although we are very careful there is always the possibility of electrical shock…..!!!

It is 35 years ago that I last received a mains shock and I remember it vividly!!

Please invite your friends and neighbours…

Best wishes
Matthew GW6KOA (Chairman)

Club Night: Mini SWR Meters

Thanks to Mathew and Trevor for a facinating evening with talks based around the VSWR meter including further developments of the active whip antenna which may be used in the very near future as a project for the Intermediate examination.

It is hoped to start running classes in the very near future for the Intermediate as about 7 members were keen to progress to this level. There may also be a Foundation course as a number of people have shown an interest. An excellent turnout of members last night. Thanks everyone.

Recent Talk on the 472KHz band

On behalf of all the club members I would like to thank our Chairman Matthew Twyman GW6KOA for his talk and demonstration of the 472khz band and especially his homebrew ‘active antenna’ based on a design by PA0RDT (Google – PA0RDT mini whip). I think his talk has prompted a few members to get their soldering irons out and to construct this very simple and cheap RX antenna….possibly a good construction project for the Intermediate licence also? Thanks Matthew.

 The photo above is of 472 KHz, the area around the red marker is 472.5 KHz cw section. Yes, the antennae really is full size! The circuit uses a 2N3819 and a BC107. As you can see, strong signals were seen using a Finningley SDR. 73 de Matthew GW6KOA
