In the news today

THE MONTHLY SARL YOUTH NET THIS AFTERNOON

A NEW 8 METRE RECORD ESTABLISHED

and

BOOKING FOR THE PRETORIA ARIA CLOSES WEDNESDAY. BOOK NOW!

Stay tuned for more on these and other interesting news items.

** The monthly Youth Net is scheduled to take place this afternoon from 16:00 Central African Time onwards on 7 070 kHz thus providing the opportunity to our younger generation to be active on the air and for young people interested in the hobby to share in the magic of amateur radio. Join Koos, ZR6KF, as he shares his experiences at the IARU YOTA event he attended in July. He will also discuss plans for the December 2015 youth month and how to participate and enjoy the fun.

Clubs are encouraged to make use of this opportunity to invite young people to their club to operate under the auspices of a licensed club member. To date this monthly activity has not been supported well, especially from clubs where no participation has been observed. We are looking forward to hear our youth on the air this afternoon from 16:00 onwards!

** Andre Botes, ZS2ACP, in Port Elizabeth worked Willem Badenhorst, ZS6WAB, in Polokwane on 40,682 MHz FSK441 via meteor scatter on 6 August 2015. This is a distance of 1 184 km that is a new South African Radio League record as well as a world record. Ian Roberts, ZS6BTE, and Willem, ZS6WAB set up the first-ever record on this band, over a Tropo distance of around 300 km.

Congratulations to Andre and Willem!

** The next Amateur Radio in Action Symposium takes place at the innovation Hub in Pretoria on Saturday 19 September. Full details are on the League home page with links to the programme and booking form. The closing date for bookings is Wednesday evening, 16 September. Do not miss the amateur radio event of the year. The first event was held at the NARC last month and received high acclaim from the participants. You will not be disappointed.

** The KLETSKOUS team is making good progress. SA AMSAT reports that the KLETSKOUS team made some major progress during the past few weeks. Currently the team is researching a new type of battery. It was planned to use Lithium Ion but one of the negatives about Lithium Ion is that it may suffer thermal runaway, which increases the risk of fire. Companies, like NEC, have developed a Lithium-Iron battery using lithium Iron phosphate (LiFePO4) as the cathode material. Generally, anodes of most batteries are made of carbon. As safety and reliability is the first concern for any battery being used on a satellite, it should not get overheated or catch fire in case of overcharging. The Lithium-Iron battery has superior chemical and thermal stability.

The team is in the process of acquiring Lithium Iron batteries to run tests. If the decision is to switch to Lithium Iron Phosphate, some modifications will have to be made to the charging circuit in the power unit but Fritz Sutherland, ZS6FSJ, says that it is not a major problem and will not delay the construction of the next prototype of the power unit.

Frik Wolff, ZS6FZ, has finalised the layout of the solar panels and Hannes Coetzee, ZS6BZP, will now proceed to mount the solar cells on a test board, which has to be carried out in a vacuum chamber. Work has also commenced on the magnetic stabilisation of Kletskous, which will be achieved by the use of orthogonal rod magnets. ZS6FZ is current working on this and reported good progress with a prototype ready for testing.

Work on the On Board Controller (OBC) is also progressing well. The first two prototypes have been completed. Brain McKenzie, ZS6BNM, is now working closely with team members to establish their telemetry point requirements and interfaces.

Nico van Rensburg, ZS6QL, has been working on the specifications and configuration management and has put a first draft on the table. The team meets via Skype on a fortnightly basis to discuss progress and plan the next steps.

Funding remains a major challenge. Radio Amateurs are urged to support the local CubeSat programme by donating to the SA AMSAT CubeSat building fund. Donors are acknowledged on the SA AMSAT web at www.amasatsa.org.za.

You are listening to a news bulletin of the South African Radio League.

The Hammies ARC make new friends in the USA. On Saturday evening 5 September at 20:00 CAT, the Hammies gathered around to introduce themselves to other young amateurs in Menominee, Wisconsin USA. The Hammies were using cell phone technology and Echo-link, node W8PIF-R, to achieve this long distance communication. This occasion had been made possible by Andries Visagie, ZS6VL, who introduced Noel Hammond, ZR6DX, the chairman of the Hammies Amateur Radio Club, to Ed Engleman, KG8CX. Ed is a co-founder, together with James Pearson, KS8O, of a group of young people who call themselves Young Amateurs Communications Ham Team, known by the acronym, YACHT. Their call sign is K8KDZ, and they have been operating since 2007. The YACHT slogan is “Connecting Young Hams, Creating Friendships, Promoting Ham Radio". The website address is www.yachthams.webstarts.com/about.html.

There was a lot of excitement from both groups as they exchanged names and call signs. It is hoped that these contacts will be made on a regular basis in the future.

Contacts must be two-way and stations must give a signal report as well as their six-digit Maidenhead Locator. Self-spotting is allowed. Log sheets must be submitted by midnight on 28 September 2015 by e-mail to contest@sarl.org.za. The full set of rules is available in the 2015 Blue Book, which can be downloaded from the Contest page on the League web site.

** In the propagation report, Hannes Coetzee, ZS6BZP, reports that the solar activity is expected to be at low levels. All visible sunspot regions are magnetically simple and non-threatening at this time. If you want to do your own frequency predictions, the expected effective sunspot number for the week will be around 43.

The 20 to 15 m bands will provide lots of DX fun, especially during the late afternoons and in the evenings. 10 m may also hold a surprise or two. Please visit the website spaceweather.sansa.org.za for further information.
