SUNSPOTS VANISH ...AGAIN: For the second time this month, sunspots have faded away leaving the face of the sun completely blank. This signals an important transition in the solar cycle: Solar Minimum is coming. Visit to learn about the down-to-Earth effects of low sunspot numbers.

TIME RUNNING OUT FOR ZU LICENSEES OVER 25 TO UPGRADE TO CLASS A - With the publication of the new radio regulations last year, the much talked about age restriction for ZU license holders was implemented.  The Authority has announced that all persons over 25 years old on 1 April 2017 can no longer renew their ZU licence. ICASA recommends that the affected persons enrol for a class A license course and write the next RAE in  October 2016. That will be the last opportunity.

The revised regulation stipulates that persons under 20 years old can write the class B examination and if successful can hold a ZU or class B license until 25 years old after which, if they would like to continue with Amateur Radio, have to sit the class A examination to qualify for a class A (ZS/ZR license).

During the discussion stage of this new regulation the SARL was requested to approach ICASA to review their decision, which the SARL did on two occasions when ICASA invited comments on their proposal.  ICASA strongly believes that the class B license prime purpose was to create opportunities for young people to enter Amateur Radio and based on that premises implemented the new regulation. 

The SARL requested ICASA to allow a reasonable period for ZU licences over 25 to upgrade. ICASA agreed to this and set the final date as 31 March 2017.. If you are over 25 and still hold a ZU do not loose out. Write the October examination. Tutorial materials is available free of charge. Download here 


SARL JOINS WRC19 DTPS  WORKING GROUP - On invitation of  the Department of Telecommunication and Postal services (DTPS) the SARL has joined the National Preparatory Working Group for WRC19. The first meeting was held on 9 June 2016 in Pretoria.The working group discussed all the WRC19 agenda items. The SARL will participate in discussions of agenda item 1.7 and 1.1.

Hans van de Groenendaal ZS6AKV will be the rapporteur for agenda item 1.1 which covers the consideration of an allocation of the frequency band 50-54 MHz to the amateur service in Region 1 in accordance with WRC15 Resolution 658. Resolution 658 invites ITU-R  to study spectrum needs in Region 1 for the amateur service in the frequency band 50-54 MHz taking into account sharing between the amateur service and the mobile, fixed, radiolocation and broadcasting services in order to ensure protection of these services.   

Agenda item 1.7 covers the study of the spectrum needs for telemetry, tracking and command in the space operation service for non-GSO satellites with short duration missions and  to assess the suitability of existing allocations to the space operation service and  if necessary to consider new allocations, in accordance with Resolution 659 [COM6/19] (WRC-15).The SARL will support ICASA who are the African leaders for this agneda item.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 26 June 2016 


RADIO TELESCOPES CURRENTLY ACTIVE IN THE KAROO – Thomas Abbott ZS6XTA (ZS1TE) informed us that the SKA-1 Mid Array isn’t the only radio telescope on the site. The radio quiet zone is intended as a national resourse, to allow other experiments to be run there too. The legislated frequency is not based solely on the SKA-1 Mid Array requirements, and anyway predates them by some years. Thomas says that he is sure that many of you have been to Sutherland, and seen the optical telescopes mushrooming on the plateau. They come there from all over the world, to enjoy the dark skies and good weather, but telescopes like company. They share the communications infrastructure, maintenance people and astronomers that are available there. 

There are currently four main radio telescopes sharing the site. KAT-7 (1 – 2 GHz), MeerKat (0,5 – 5 GHz), HERA (120 – 190 MHz) and C-BASS (5 – 6 GHz), with SKA-1 Mid Array prototypes starting soon. HERA (see ) is an interesting low-cost single-purpose radio telescope. It is built with wire mesh reflectors, PVC pipes and copper pipe dipoles. It started as a smaller cheaper radio telescope called PAPER, which has been observing for some years. 

THE HISTORIC ROAD FROM 112 MEGACYCLES TO 144 MEGAHERTZ – In 1934 all the frequencies above 30 MHz were known as the Ulta High Frequencies and were believed to be only suitable for line-of-sight (LOS) communications. When Ross A. Hull, VK3JU, immigrated to the USA and joined the ARRL as Associate Editor of QST, he became interested in conducting long distance experiments on 60 Megacycles (as it was called then) in the 5 metre band. He was located at West Hartford and began running nightly tests with amateurs in Boston about 160 km away. At first they heard nothing, until he tried a beam antenna consisting of 4 radiators and four reflectors. On some nights very strong signals were received. He soon discovered that these strong signals were caused by refraction in the troposphere when temperature inversions occurred. 

In 1935 he turned his attention to the 112 Megacyle (212  metre band) and managed to work Boston also at times on Tropo. After the WWII the 112 MHz band was replaced with 144 MHz (2 metres). Receiving and transmitting equipment including beam antennas were improved over the years, resulting in two-way communications between California, USA, and Hawaii over a distance of almost 4000 km. Experts believe that 144 MHz will be the VHF band that will bridge the Atlantic and Indian Oceans during Tropo Ducting propagation over the distances of 6000 and 8000 km, respectively. 

A 144 MHz UK SIGNAL HEARD ACROSS THE ATLANTIC – The RSGB reported that a 2m signal from the UK was heard across the Atlantic on 2 May. It had been reflected off the structure of the International Space Station (ISS). Following two weeks of preparation, Tim, G4LOH, in Cornwall and Roger, VE1SKY, in Nova Scotia attempted a FSK441 contact. With a mutual window of less than one minute, VE1SKY was able to copy G4LOH at a distance of 4,441km. This was the first signal received via ISS-bounce from Europe to North America, and the first intentional signal heard via ISS reflection in any direction across the North or South Atlantic. 

MORE TRANSATLANTIC NEWS – A letter from Pieter V51PJ to Bruce ZD7VC on St. Helena Island reads: “Hi Bruce hope all is well that side with all the coldfronts etc. passing over there. Conditions look favourable between ZS1, ZS3, V51 to ZD7 on Hepburn site for 2m ducting. Please advise on availability. My suggestion is to listen on 144,250 MHz monitoring JT65b or 144,300 MHz SSB voice. My beacon is also running on144,42960 MHz CW or 144.429 MHz USB. Please advice on conditions. Pieter V51PJ. 

A reply came from Bruce R. Salt, ZD7VC, St. Helena Island: “No good propagation here at present unfortunately.  Looking at the predictions it looks like it might be good on the coast but out here in the Atlantic it’s extremely poor. My AIS station is only copying signals from my horizon 45nm, nothing beyond and it’s been like that for months now, sometimes I wonder if it’s worth leaving the computer running 24/7! I will keep my ears open though and let you know when I start hearing signals. Good to hear from you. 73 Bruce.” 

VHF REPORT FROM PRETORIA – “Last night the 21st June we had a well attended net and a few new operators with VHF horizontal Yagi's. We mainly worked on FM and horizontal and it was very pleasing with the distances we were able to achieve on horizontal polarization. From Pretoria towards Krugersdorp on normal vertical antennas we were struggling to have QSO's but last night with the horizontal Yagis and FM we managed to have QSO,s with between 5/7 and 5/9 reports with ZS6CBQ, ZS6EFN, ZS6QTF, ZS6GJV and ZR6CMG. ZS6QTF has a small 3 element Yagi and that alone was a very big improvement on the distances he managed to work.

“If possible we would advice that a small Yagi or even a loop antenna be installed horizontal it will open up a new world on VHF with much greater distances to be achieved. From Pretoria we also managed to join the Kempton Park net on 144,300 MHz SSB vertical and had a few nice short QSO's. The following stations were active on VHF last night: From Krugersdorp ZS6CBQ, Pretoria ZS6EFN, ZS6GJV, ZS6QTF, ZR6CMG and ZU6CC, including Kempton Park ZS6BT, ZS6VB, ZS6UD and ZS6UB. 73 Jaco ZR6CMG, KG44ch.” 

“Very nice report Jaco. I would like to thank you for your energy, inspirationand all the hard work you have done so far. You made a big difference to the VHF in the Pretoria area. Carl ZS6CBQ.” 

VHF DIGITAL BEACON BEAMS ACROSS THE ATLANTIC –  On 19 May 2016, antennas were erected and the VHF SDR turned on to inaugurate the VO1FN/b Transatlantic VHF Digital Beacon Receiver Site. This is a joint project sponsored in part by the Society of Newfoundland Radio Amateurs, Baccalieu Amateur Radio Club and the Upper Trinity Amateur Radio Club. The VHF Digital Receive site is now operational and ready for experimentation by beacon operators and well-equipped VHF stations in Europe. The antennas, two InnovAntenna 5 element LFA Q High Gain VHF Yagis, can be rotated to point to stations that are located in southern regions of Europe. According to Frank Davis, VO1HP.the receiver site is up and running using an SDR and SDR Console software. He explained that users would first have to install SDR Console V2.3, and he would open a free account permitting them to log in. Davis said the receiver has been listening continuously on 144,488 MHz for any JT65 signals from Irish beacon station EI2DKH, operated by Tony Baldwin, EI8JK

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.
