NARC Membership 2023.... Subs overdue

Details

Published: 27 October 2022

Last Updated: 02 January 2023

The clubs officers and committee have decided to reduce our previous precovid full NARC membership which was £20 - £30 per year to just £10 per member for 2023.  We can do this principally because we have more members than we used to have and we physically meet less often than we used to and although the school hire costs to us have risen by more than 30% we do not incur any costs for producing NARC Live online. (NB The £5 rate for 2022 was set in October 2021 and was based on the clubs costs of having no in person meetings).

We appreciate the huge cost of living pressures which are upon us all, so we are taking a leap of faith in reducing our full membership price to the lowest it has been since the 1980's, in the hope and belief that everyone will continue their membership of NARC for a very modest outlay to a club which meets, arranges events and does something online for at least 50 weeks of the year - equivalent to 20p per week. 

Club Contesters Note that if you are a contester for NARC please remember you need to be an up to date paid member to enter valid scores into the club championship contests.

So we ask you to rejoin (or join) NARC now for 2023 and pay us ideally by direct bank transfer - be sure to use your callsign/surname as reference. Please also complete and email the membership form if you are not already current member so that we can register you. 

(NB - As Mark asks please pay by BACS bank transfer if you possibly can because even though we are a voluntary organisation Paypal still take a significant commission along with the bank which also charges for each Cheque payment because our account is classed as a business)

Ian GM3SEK Filter kit - Where to buy and NARC Member feedback...

Need Filter parts?  

(This article is also updated with members feedback lower down)

Several people have asked where they can buy parts from for the Filter kit, either because they missed the NARC bulk buy in December, or they want to buy a few extra parts.

The article as described on NARC Live was recorded and the recording can be seen here:

https://www.youtube.com/watch?v=LVTuBsj3U0o

Ian's GM3SEK website with excellent projects - scroll down for the Filter project including the complete slide set of the presentation which shows construction in more detail.

https://gm3sek.com/

The following are the main components of the kit as specified by Ian along the suppliers you can buy them from which are either used by Ian and or myself when I organised the NARC bulk buy. They are not necessarily always the cheapest supplier, but they are consistent suppliers and all parts are in stock as I write this on 18.1.22.

Tip: Label your Ferrites with their part numbers as soon as you receive them as they look identical to others yet perform very differently!

Cable

High temperature flex such as 3093Y 2.5mm is recommended for the filter and this is available from several sources online and locally, eg Screwfix supply 5m lengths as below for collection from a local branch and you will need at least 3m for the filter as described.

Cable update 3.2.22:

Thanks to John 2E0TWQ who shares that Screwfix are currently out of stock but he found it available on eBay under item number 202336536417

David G7URP's buying notes

Note that Mouser has warehouses in Germany and USA but currently if you order over £45 shipping is free and VAT prepaid - the £45 should be exceeded if you purchase the mains filter and ferrites from them all at once.

This information was my experience and is offered in good faith but neither NARC or I can accept responsibility for any errors or problems ordering parts or performance of the filter etc.

NARC Members additional feedback on the Mains filter which came in after the show...

From John 2E0TWQ:

A very useful video showing how to make the filter:

https://www.youtube.com/watch?v=ECogK3pCp28

And a surplus filter which might be useful as found on eBay but the seller has a large quantity:

From Ralph 2M0RHT

I attach photos which I hope help others. It works for me so I must be doing something right. A bit of experimentation does no harm. For me, the + and - go through the filter therefore the earth should do the same. Therefore I constructed my filter as per the photo. Hope this helps others.

From Malcolm G3PDH:

David,  a very interesting discussion on Wednesday.  

Just to reiterate my points, Firstly there seemed to be debate on some reflectors about which way round the metal can filter went.  I assumed that LINE was the mains in and LOAD the output to the toroidal and output.   
My mains earth connects through from the earth tag on the can filter to the cables going around the toroids and to the mains output from the filter.  I have not connected that earth to anywhere else such as an external earth.
A definitive circuit diagram would be useful and confirmation as to the direction of the can filter.
As I said I don’t seem to have any mains borne interference but decided to keep it in circuit as good engineering practice and it could help with any RF going back into the mains from the TX, particularly the Linear Amp.
