SILENT KEYS

It is with regret we advise that the keys of two radio amateurs stopped operation on the same day last week.

That of Chris Willigenburg, ZS6VB, went silent after a short period of fighting a battle with Leukemia. Chris was very involved with Hamnet and was Provincial Director for Gauteng South for a period a few years back. He leaves Linda, his wife and 2 daughters.

That of Rodney James, ZR6NTN, went silent at the age of 58 after a short illness.

Rodney was licenced in 2009, and was a member of the Sandton ARC.
He leaves his wife Delilah and adopted son Ryan.

We offer our condolences to their families and friends.

RADIO TECHNOLOGY IN ACTION ON 1 SEPTEMBER IN PE

MTN TO SPONSOR RADIO AMATEUR AWARDS - NOMINATIONS ARE INVITED

BPL WAR: EU VS RSGB OVER BPL STANDARD

You are listening to ZS6SRL. Stay tuned for more details on these and other important and interesting items.

RADIO TECHNOLOGY IN ACTION ON 1 SEPTEMBER IN PE

Register now for the SARL Radio Technology in Action Symposium to be held at the Nelson Mandela Metropolitan University in Port Elizabeth on 1 September 2012. The event features an exciting keynote address by Jason Manly of SKA South Africa.

He will discuss the road to the world's largest science instrument, the Square Kilometre Array. There'll be a specific focus on South Africa's part in this project, both from technical and human capital development viewpoints. South Africa's own KAT-7 and 64-dish MeerKAT arrays that are currently being deployed in the Karoo will be described in some detail along with how these are leading towards the SKA. The SKA itself will consist of three separate array types built in two phases over multiple continents. What does the right to host this premier international instrument mean for South Africa and Africa in general?

Jason told SARL NEWS: "With my background in signal processing, there'll probably be a bit of a bias towards SDR, but I'll keep it interesting describing everything from antenna feeds and reflector design to signal transport and data post processing, with a few slides about the science goals thrown in for good measure!”

We promised that the Port Elizabeth RTA would have a very special keynote. We are able to deliver on that promise with a very special hour.

The rest of the programme will follow the programme presented at the Durban and Gauteng RTA with plenty of hands-on type presentation.

Pre-booking is recommended to ensure that enough 80 metre experimental SDR kits and CD's are available. It also assists with the catering. A registration form can be downloaded from www.sarl.org.za as well as a detailed programme. Pre-booking closes on Thursday evening. So do not delay. All persons who pre-book will take part in an additional draw for the ARRL Basic Antenna book.

You can register at the venue on Saturday morning but pre-booking is preferred.

MTN AMATEUR RADIO COMMUNITY SERVICE AWARD
Annually the South African Amateur Radio Development Trust is recognising a radio amateur or a group of radio amateurs for service to the community.

Community service can be assistance to a handicapped radio amateur, communications support during a sporting event or a disaster situation like a road accident or a natural disaster like a flood, veld fires, or an earthquake.

BPL WAR: EU VS RSGB OVER BPL STANDARD

A battle appears to be brewing between the Radio Society of Great Britain and the chairman of the European Union Committee. This after the latter attacked the RSGB's call to arms in the battle against Powerline Transmission radio pollution according to a report on Newsline.

The chairman of the European Union committee on Powerline Networking has responded to the Radio Society of Great Britain's call to arms, claiming that every minute of filibustering pollutes the radio spectrum more.

According to the UK newspaper the Register, the Radio Society of Great Britain says that the new standard for broadband powerline transmission, will water down existing requirements. This it says will open the way to greater spectrum pollution. As such, the RSGB has asked members to lobby their local representatives.

But Ronald Storrs, Chair of the committee defining the standard, refutes that. He claims that it is the RSGB that is risking the airwaves with - and we quote" "their pointless protests and inflexible attitude."

The problem is that sending data signals over unshielded mains wiring, as Broadband Over Powerline transmissions does, generates radio interference. And as the manufacturers push to increase speeds that interference is spreading into the frequencies used by other radio services. That, says the RSGB, is unacceptable.

But BPL or PLT equipment manufacturers have a totally different view. They say that the devices don't generate significant interference. Rather it's the mains wiring thats the culprit. The manufacturers also contend that in many homes the wiring is sufficiently shielded that no interference is generated. As such they will continue to sell their devices legally.

Meantime UK telecommunications regulator Ofcom has taken a back seat in this matter. It says that it can't do anything as the devices themselves aren't radio transmitters so fall outside their purview. Ofcom says it's waiting for the new standard to be enacted which will give it some authority to regulate Broadband over Powerline technology.

So it appears that a proverbial line has been drawn in the sand between the UK amateur radio community represented by the Radio Society of Great Britain and those who want to sell Broadband Over Powerline or PLT gear. And while the European Union's Storrs agrees that BPL is generating unacceptable interference, he says that every day there isn't an applicable standard in place more unrestricted gear is getting into the marketplace. He adds that the intransigence of United Kingdom's amateur radio community isn't helping.

CPUT CUBESAT TO LAUNCH END NOVEMBER

The CubeSat designed and built by students at the Cape Peninsular University of Technology in Bellville will be launched towards the end of November. Still known by its engineering name ZACube-1, the satellite will be shipped in the next few weeks to Holland where it will be integrated with two other CubeSats in the launch carrier before being shipped for integrating with the rocket. ZACube-1 carries a HF transmitter operating on 14 099 kHz, a small camera and a telemetry transmitter. Listen to Amateur Radio Today this morning for an interview with Francois Visser, of CPUT who is leading the project.

ZS6PTA SPRING FLEA MARKET AND BOOT SALE IN PRETORIA

The Pretoria Amateur Radio Club will be hosting their spring flea market and boot sale on Saturday 1 September. The fleamarket will be held at Pretoria Motor Club in Keuning street in Silverton. The starting time is 08:00.

Everyone is welcome to attend. Come and visit the Mega Fleamarket in Pretoria. Phone Almero, ZS6LDP, on 083 938 8955, if you want to book a table or if you need more details about the flea market.

PROPAGATION REPORT

Hannes Coetzee, ZS6BZP, reports that the solar activity is at low levels. There are currently a few sunspot regions visible but fortunately some more are in the process of being formed.

If you want to do your own frequency predictions, the expected effective sunspot number for the week will be around 41.

All the bands from 20 to 10 m will provide lots of DX fun with 20 m providing the best openings with 15 m not far behind. 10 m openings will be less frequent due to the lower solar activity.

Please visit www.spaceweather.co.za for further information.
