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

We begin this bulletin with the news of a silent key:

It is with deep regret that we announce the passing of Daryl Lamble, ZS6DLL in the early hours of Sunday 1 December. Daryl was a keen CW operator took on the challenge of training others in CW. He was awarded the 2018 Jeffrey Wright Trophy by the AWA for contributing the most to CW and he was responsible for seeing an increase in CW on the bands and had an absolute passion for it.

Our deepest condolences to his wife Kim, daughters Kevone and Bianca, family and friends.

SARL News has heard that Gerard de Jong, ZS6KX has become a silent key, but has no further information.

PAUSE

THE 2020 PARKS-ON-THE-AIR PROGRAMME

At present there are 545 Parks registered for Southern Africa on the Worldwide Fauna and Flora database 8 in Eswatini, 7 in Lesotho, 13 in Botswana, 10 in Mozambique, 26 each in Namibia and Zimbabwe and 455 in South Africa. The Southern African Parks-on-the-Air programme will run 1 January to 31 December 2020 with various awards available for activators and chasers.
For an activity to be valid, you must make sure you and all your gear are inside the reserve, on foot, bicycle, motorbike, car, motorhome. You must make 10 QSOs (44 QSOs for the international awards) for your activity to count towards an activator award, but the QSOs can be made over a number of days. You can only work from one reference at a time - so if you are in a park that is a sub-region of a larger park you can only use the reference of the sub-region. You will also have to provide photographic proof of your activity using pictures of a GPS device (car navigation for example), park signs and your set-up.

The Park-on-the-Air website and the various awards are being finalised and more information will be available in the January 2020 issue of Radio ZS.

FIRST CALL FOR PAPERS FOR THE SARL UNLOCKING AMATEUR RADIO TECHNOLOGY SYMPOSIUM

This is the first call for papers to be presented at the second SARL Unlocking Amateur Radio Technology symposium to be held at the Wanderers Conference Centre in Johannesburg on Friday 3 April 2020. Following the very successful event in Stellenbosch last year, the same format will be followed. The symposium will open with registration at 13:00 with the conference starting at 14:00 and will conclude at 19:00 with a cocktail event.

Prospective authors are invited to submit a short synopsis of their proposed paper, in a Word file, by Wednesday 15 January 2020 for review. The final programme will be published by Friday 31 January 2020. The speaking slots are 20 minutes with 10 minutes allocated for questions and answers. There will also be four "quick fire" sessions of 10 minutes each. Send proposals to artotoday@sarl.org.za

The Unlocking Amateur Radio Technology Symposium is part of the SARL National Convention which includes the Annual General Meeting and annual Awards Dinner. Diarise the weekend of 3 to 5 April 2020 as an Amateur Radio experience not to be missed.

AMSAT SA TO SHIFT MAIN FOCUS TO AFRICUBE, A DIGITAL SDR CUBESAT

The AMSAT CubeSat development team has shifted their CubeSat development focus from an analogue transponder to a digital SDR based unit. The development of the AfriCUBE digital SDR transponder under the leadership of Anton Janovsky, ZR6AIC has reached an advanced stage and will soon be ready to undergo its first field trials.

The team is not abandoning the development of the KLETSKous analogue transponder, which performed well during the BACAR 7 flight on 12 October 2019. Leon Lessing, ZS6LMG has taken the development to this point but unfortunately, due to personal commitments, cannot continue to work on Kletskous. "I would like to thank Leon for his support and wish him well in his future endeavours," Hannes Coetzee, ZS6BZP, AMSAT SA CubeSat project leader said.

During the BACAR flight test it showed that some further development is needed to improve the transponder's receiver sensitivity. "Here is a great opportunity for young enthusiastic engineers in the amateur radio community to take on the challenge. I invite interested persons with RF experience to contact me and become part of the team. While there is no financial reward, the experience and achieving something great that will fly in space outweighs this many times. It will certainly look good on anyone's CV", Hannes said.

The EPS (electronic power system), space frame and stabilisation system are complete. The development of the solar panel and antenna deployment systems are making good progress. Frik Wolf, ZS6FZ said he will be ready by mid-January 2020 for project review and field testing.

Currently work on a new onboard control system has been paused while Fritz Sutherland, ZS6FSJ is working with Anton Janovsky to get AfricaCUBE ready for on-the-air trials.

Nico van Rensburg, ZS6QL will continue work on the documentation crucial to secure a launch opportunity and Hans van de Groenendaal, ZS6AKV will work on frequency allocations and explore launch opportunities and the marketing of the project.

AMSAT SA is continuing its dialogue with SANSA and its contractor to place a transponder on EOSAT- 1, a planned high performance earth-observation satellite designed to produce data for a broad range of earth observation applications. The development of AfriCUBE will enhance this opportunity.
