Vortex Antenna Systems

Comments Off on Vortex Antenna Systems


We’re very proud to announce that as of 12/12/2010 VORTEX ANTENNA SYSTEMS will be retailing following an initial extended period of R&D.
Vortex is owned and run by IOTA enthusiast Steve Lawman (G0UIH/VK2IAY/3D2FI) and is ably assisted by his XYL ‘Gail’ from an office and workshop near to Peterborough.

In the past the UK has had a limited choice for the radio community when it comes to home‐grown HF antenna products (particularly beams etc), so Steve has spent a period sourcing and researching premium quality aluminium and hardware to compliment the new VORTEX product line up.
Initially the line‐up will include the ‘Tornado’ range of HF Yagis and the ‘Whirlwind’ range of HF Delta Loops with mono and multi‐band variants. The mainstay is a heavy duty range, but certain products are also available as a lightweight alternative. A section on 6 and 4m antennas is also included. The product list will expand into 2011 to include Linear Loaded Designs and vertical antennas.

The portfolio also includes a variety of ‘VORTEX’ hardware and accessories which is aimed directly at the home constructor enabling them to purchase genuine VORTEX components and associated high end parts for their own antenna projects.

Commenting on the launch, Steve said that “During the last 18 months I’ve been sourcing materials and liaising with a variety of high‐end UK manufacturers. We have some good aluminium off the shelf stock available in the UK but the constructor is let down by the lack of suitable wall thicknesses.

Finding premium grade aluminium together with the correct ‘Wall Thicknesses’ that allows secure element telescoping was of paramount importance. Our bespoke stock of UK manufactured metric 6082‐T6 and AA6082‐T6 aluminium element tubes gives us 5 different tube diameters (soon to be 6), and a strength which exceeds that of the high end US 6061‐T6 ‘Aircraft Quality’ aluminium, but still retains excellent corrosion resistance. The element clamps are sourced from the Oil, Gas and Hydraulics industry and the element to boom clamps, Stainless Steel U‐Bolts and Saddles are all our own designs. We also use stainless steel fittings throughout. VORTEX now gives the UK radio enthusiast access to premium quality antennas and parts on their own doorstep without having to go out of the country”.

VORTEX hope to be attending some of the UK Rally dates throughout 2011 and to hopefully include some international events into 2012.

Vortex are primarily an on‐line only retailer. All antennas and accessories can be ordered directly online at www.vortexantennas.co.uk Alternatively, Steve can be contacted at the workshop on 07943 871 893, by email to [email protected]

SDARC Awarded Lottery Grant

Comments Off on SDARC Awarded Lottery Grant

Many amateur radio clubs in the UK are missing out on thousands of pounds in grants because they fail to put in bids for Lottery money.

Although it can take some time to organise a lottery bid, the benefits of doing so can be huge. The Swindon & District Amateur Radio Club (SDARC) are one of many community projects in the United Kingdom to be awarded grants from the Big Lottery Fund.

The fund’s Awards for All programme will see a £9,960 grant handed to SDARC, to buy equipment, enabling it to extend its activities and enable local people to learn about the hobby and to get involved.

SDARC spokesman James Patterson said: “It’s fantastic news, and we are obviously very grateful to the National Lottery for the grant. This is a massive investment, and a big opportunity to promote the hobby, the society, and what we do in the area.

We hope to help educate the young and old in the skills needed to operate radio equipment, skills which are very useful in a number of careers.”

Thanks to the lottery grant, the club will be investing in radio transceivers, accessories and other items to enhance our training, operational and promotional activities.

The Big Lottery Fund distributes funds on behalf of the National Lottery to good causes across the UK,and aims to enable others to make real improvements to communities and the lives of people across the UK. Application information can be found at www.awardsforall.org.uk

The club meets weekly, every Thursday in the Savernake Street community halls. SN1 3LZ from 7pm-10pm. Contact Den on 07810 317750 for details.

144MHz Linear (3w in 1300w out!)

Comments Off on 144MHz Linear (3w in 1300w out!)

Lionel, F1JRD has developed a state of art SSPA for 144 MHz that delivers up to 1300 Watt output with just about 3 Watt input.

Just a single brand-new transistor that was released in November 2011 from freescale is used in this PA. As this transistor costs just below 240 Euro (320 USD, 200 GBP) this results an amazing pwr/money ratio.

The PA is supplied with a cheap surplus 48/50V DC source. Lionel has presented the PA in the latest issue 4/2010 of DUBUS Magazine.

A seasonal video from Gary Pearce KN4AQ

Comments Off on A seasonal video from Gary Pearce KN4AQ

A little holiday cheer from ARVN”s KN4AQ.

From YouTube:

“I wrote the poem back in 1996, and recorded an audio version a few years later. In 2009, my friend Don Mercz WA3AYR recorded a Christmas medley on guitar, and I thought it would make a good background for the poem, so I mixed them.

Then I thought “video” (that”s my business, you know). But what could I use to illustrate the poem? Live action? Too complicated. Animation? Too extensive.

How about December QST covers? Most years they have a holiday theme. I asked the publisher, and he said “sure!”
But the covers didn”t have quite enough material, so I turned to the ads to fill things out (and contacted all the advertisers that were still in business – most were from before 1960).

So here it is. I hope you enjoy it!”

Comments Off on Construction Contest : 10th March 2011

The 2011 Annual SDARC Construction Contest will be held on March 10th 2011.

We are announcing this event now, in order to give members as much time as possible to build some equipment to enter in the contest.

The contest will have five general categories:-

Homebrew – This will be for equipment built completely by the club member. (If the equipment is a magazine project with a pcb available, then, the pcb may be used.)

Antenna Installations – This will be for special homebrew antenna systems. For this type of contest entry, the member will just need to provide photographs of the antenna together with a specification, a drawing and details of the construction. A list of countries worked with the antenna should also be provided.

Kit – This will be for equipment built from a kit.

Hybrid – This will be for homebrew equipment, which contains one or more kits.

“First Timers” – This will be for club members who have not previously built any equipment.

There will be a total of eight awards allocated to the five categories; the number of awards per category will be up to the judges to decide.

In addition there will be a special award:-

“Professional” – This prize may be awarded to experienced constructors whose work is of an exceptional standard.

The judges’ decisions on all the awards are final.

Items must have been built in the last two years to be accepted as an entry. The entries can be any radio-related equipment, for example, morse oscillator, test unit, QRP rig, computer/radio interface, psu, Tx/Rx, linear, antenna installation.

The most complex equipment may not necessarily win!
