SA AMSAT AIMS KLETSKOUS LAUNCH FOR JULY 2017-  At the pre-conference Engineering meeting held on Friday evening, members of the SA AMSAT CubeSat team made some tough decisions. During the past few years, various options and subsystems have been experimented with. The team has now set the launch date of Kletskous at July 2017 with the first flight model to be ready by February 2016 for testing after which final integration will start. This requires that various module designs are locked down and built by October 2015. It is planned to have all the modules wired together in a breadboard configuration for testing the interoperation of the various subunits by December 2015. Some modules are at a more advanced stage than others, but in the next few months, the team expect to catch up and meet the deadline for the first breadboard test.

Frik Wolff, ZS6FZ, the League's technical manager, has joined the team and is working on solar panels and stabilisation issues. Francois Oberholzer, an honours student at Stellenbosch University, is working on improving the weight/strength relationship of the space frame, a project that is part of his thesis. Nico van Rensburg, ZS6QL, as programme manager and the person responsible for documentation, will support the project manager, Hannes Coetzee, ZS6BZP. 

There are many opportunities for radio amateurs to join the engineering team. If you have a particular expertise or passion to add value to the KLETSKOUS project, please discuss your participation with Hannes Coetzee or any of the team members and send your details to,za. There will be a fuller discussion about KLETSKOUS in Amateur Radio today later this morning.

 #RENEWAL OF AMATEUR RADIO LICENCES AND FORM B - Form B is no longer required. Amateur radio licenses are due on 31 March 2015 ICASAhas sent out reminders in January but the responsibility remains with the licensee to ensure that the license is paid. Unpaid licences will expire at the end of April.Radio amateurs also have the option to pay for 5 years. Simply send an email to  and advise him that you are converting to a 5 year license then when making payment, pay R500. This is a saving of R100 and protects the licensee against inflation increases which will be introduced from the 2016 license year.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM (29 June 2015) 

# Link to SARL VHF, UHF & MICROWAVES DX TABLE Click here  

THE AMATEUR RADIO SERVICE COVERS A VERY WIDE FIELD – Most people believe that radio amateurs only talk to each other on the radio, or some make DX contacts on HF and collect QSL cards. This is of course great fun, exciting and the way how Amateur Radio started. But in fact this is only one facet of the modern Amateur Radio Service as it covers a very wide field of activities. It is not just a hobby as some seem to think, but it also features experimentation, exploration and research of VHF, UHF and Microwaves, EME, Satellites, Space communications, Amateur radio astronomy and the new frontier in the Terahertz spectral band. The modern Software Defined Radio (SDR) and Digital communications should also have greater appeal to the younger amateur generation of today. 

NASA PREPARES FOR FIRST INTERPLANETARY CUBESATS – NASA will launch two CubeSats to Mars in March 2016, the first time that these miniature satellites will fly into deep space. The idea is based on the many CubeSats built by university students and launched into Earth orbit. One of the CubeSats will land on Mars while the other orbits the planet, and communicate via UHF (receive only) and the X-band ( receive and transmit). 

PORT ELIZABETH NET ON 144,300 MHz SSB –  A VHF net on 144,300 MHz SSB has been started in Port Elizabeth by Ken Victor, ZS2OC, operating on Thursday evenings at 20:00 CAT. Amateurs along the line such as in Jeffreys Bay, Uniondale, Knysna, George, Dana Bay and Cape Agulhas are invited to join the net when propagation conditions are favourable. The main motive is to establish two-way contacts with Cape Town over a distance of 600 km. 

BEACON REPORTS – Some VHF beacon results as received at the QTH of Koos du Plessis, ZS6BFD.

08:00 - 08:20 CAT – 144,415 MHz - Bloemfontein - 365 km - Best S5 - No pre-amp.  

08:20 - 08:40 CAT – 144,410 MHz - Polokwane - 297 km - Best S4 - No Pre-amp.

08:40 - 09:00 CAT – 144,420 MHz - Durban - 506 km - Nothing - Using pre-amp.

Anytime CAT – 144,440 MHz - Tarlton, Gauteng - 25 km - Constant S9 - No Pre-amp.


VHF FROM GAUTENG – “A big Congratulations to Gideon ZS6GJG from Phalaborwa for working several stations in Gauteng from Phalaborwa, a distance of 415 km, during the past few days. John ZS6JON was the first station to work Gideon on Thursday evening at about 20:00 CAT, reports were 5/1-3. This morning Andrew ZS6AVH in Krugersdorp was in contact with Gideon on 144,320 MHz the whole time and signal reports of 5/7 were exchanged. Gideon also worked Dick ZS6BUN at Nigel 5/1. Although Gideon could hear Koos ZS6BFD and myself at 5/1 it was just not possible for us to get him out of the S 4-5 noise level when beaming over Johannesburg. Gideon is using an IC7100 with a 80 Watt amp into a 9 element ZS6OB Yagi at 14 meters high. It looks like 2 meters are full of surprises even in the winter. The VHF group is spreading wider and wider, so please come and join us on week-ends. 73 Carl.” 

“OK so I have a SSB set with 100 Watts and a 4 element beam about 7 metres up. Where do I point it from the West Rand tomorrow morning? Rory ZS6RBJ.” 

THE SOUTH-EAST COASTAL GROUP – “As promised Dave ZS5DJ and I came on sked as promised on both Sunday and Monday evenings (21st & 22nd) at 20:00 CAT on 144,300 MHz USB horizontal, and we had a QSO on both evenings. Conditions were not as good as the Hepburn Charts predicted, but then they are only a prediction. We both listened out for other stations, but none were heard. 73 Peter ZS2ABF.”


24 GHz EME WORLD RECORD – VK7MO operated portable on 24 GHz EME from South-East Tasmania to OK1KIR over a distance of 16 438 km, and then established a new World Record with G3WDG and G4KGC of 17 464 km. Only a few days each month are suitable for such long distance QSO’s, and then one must have low PW and no cloud or rain at both ends. The equipment used at VK7MO: 1,14 metre dish and 20 Watts fully GPS locked and corrected for Doppler. OK1KIR: 4,5 metre dish and 22 Watts output transceiver GPS locked. G3WDG: 3 metre dish and 18 Watts output transceiver GPS locked. 


NEW BROADBAND COMMUNICATION CENTRE OPENED IN PORT ELIZABETH – The Minister of Science and Technology, Naledi Pandor, welcomed the launch of the new Centre for Broadband Communication at the Nelson Mandela Metropolitan University (NMMU) in Port Elizabeth. The centre will conduct pioneering research around optical fibre data transport for the Square Kilometre Array (SKA) radio telescope.

At their meeting at the SKA Organisation Headquarters in Manchester, UK, the SKA Board of Directors has unanimously agreed to move the world's largest radio telescope forward to its final pre-construction phase. The design of the €650M first phase of the SKA (SKA1) is now defined, consisting of two complementary world-class instruments – one in Australia, one in South Africa – both expecting to deliver exciting and transformational science.

What is Amateur Radio ? 

Tell me more  about Amateur Radio

Radio Amateurs, or "Hams" use two-way radio communication to make contact with other radio amateurs all over the world. They are even able to use satellites and on occasion speak with astronauts. Radio Hams can do this from home or while mobile in cars, boats or on foot.

Radio Hams have a full range or communication modes at their disposal. These include plain voice, Morse code, numerous digital computer modes and even graphical modes like television. As a licensed amateur radio operator you will be able to join in experiments using all these modes.

mateur radio can be enjoyed by young and old, male and female, even the most severely disabled can make friends around the world from their own home. This hobby knows no boundaries.
