South African Radio League Website Development - SARL President, Nico van Rensburg clarified the situation with regard to the League website. There have been a number of comments and statements made recently with regard to the League website. This statement serves to clarify the situation.


The current South African Radio League website is fully functional and serves the members as intended.


The Council is presently undertaking a review of the Information Technology systems used by the League to serve its members and the broader amateur radio community. Part of the review is to determine ways in which the League website and services on the website can be brought up to date and take advantage of the advances in the use of social media.


Council has established a working group to prepare a Requirements Specification setting out the South African Radio League IT requirements going forward. Council will consult with the Members before the specification is finalised and the go ahead given to begin the technical work of developing an updated platform.


The President also said that the Webmaster has been able to negotiate reduced hosting and service rates for the existing infrastructure until such time as a formal project plan with the appropriate costing has been put in place.

SDR workshop in Cape Town on 25 March 2017Following on a very successful symposium on Software Defined Radio held in Gauteng towards the end of last year a similar event will be presented by AMSAT SA in the Cape on Saturday 25 March 2017 at the Bellville Campus of the Cape Peninsula University of Technology.

The programme includes topics relevant to amateur radio, and will provide some background on SDR. A practical approach of how to use readily available dongles in conjunction with your PC to set up a receiving system operational from the low MHz frequencies up to nearly 2GHz. will be described

To give attendees an insight into the development of such systems some of the software available to perform this task will be demonstrated. Hardware availability suitable for the development of embedded systems required for standalone transmitters and receivers will be introduced.

Looking at the rapid development of radio communication, and the future challenges within this field of technology, it is of importance for young as well as established Radio Amateurs to keep abreast thereof. More details and registration form soon 


RSGB HANDBOOK NOW AVAILABLE IN SA- The new RSGB Radio Communication Handbook is now avaiable in South Africa. Also available are the ARRL 2017 Handbook (hardcover version) and Low Band DXing. For a list of books locally stocked and a mailorder from click here. SARL Members get up to 10% discount .

RAE Examination details for 2017 - It's the time of year again when clubs get ready to run RAE courses.  This year sees a major change in the day of the exam. In the past, the exam was always written on Thursday evenings, but this year the RAE exam will be written on Saturday mornings starting from 10:00 to 13:00.  This should make it easier for the candidates who can't always make the exam, due to work pressures.  

The RAE dates for 2017 are as follows:

 1st semester

21 January 2017 - RAE registration process opens.
15 April 2017 - RAE registration closes.
20 May 2017 - RAE examination (Saturday morning) 

2nd Semester

14 July 2017 - RAE registration process opens.
16 September 2017 - RAE registration closes.
21 October 2017 - RAE examination (Saturday morning) 

4 Bursaries available for under 26 to study for class A -  If you are under 26 and planning to study for  the Class A amateur radio examination there are bursaries available.. For more detail and application forms click here. 

HAVE YOU PAID YOUR LICENCE?- You are advised to make sure that you have paid your amateur radio license for this year. If not it is recommended that you do it without delay. ICASA is not obliged to send out statements, the onus is on the license holder. If you have not paid for the 2016/2017 year, pay R559 and you are covered for this year and the next 4 years with no increases.  The fee for the current 2016/2017 year is R134. 

ICASA is in the process of implementing an ICASA Council decision to cancel all licenses that are not renewed within 30 days of 1 April. While still in the implementation planning stage make sure you have paid this year’s licence fee. Failing do so will mean that you may have to apply for a new license. You may just find that some else has applied and obtained your callsign.

The International Amateur Radio Union Region 1 Monitoring System January 2017 newsletter reports a mysterious 'foghorn' that is a Chinese over-the-horizon burst radar is operating in the amateur radio bands. The mysterious foghorn on 7, 10, and 14 MHz is often jumping with the signal frequency modulated on pulse with 66,66 sweeps-per-second bursts.

The latest IARUMS newsletter also reports strong splatter from Radio France International on 7 205 kHz down to 7 186 kHz. The French Member Society, REF, has informed RFI and French telecommunications authorities.

Full details of these and other interference matters can be found at

3Y0Z Bouvet News (Team Member Update). On 12 February, it was reported on the 3Y0Z Web page at that Jorge, HK1R, would not be able to join us on the Bouvet DXpedition. Jorge was with many of us on the Malpelo DXpedition and the Amsterdam Island DXpedition. We will miss him greatly on the upcoming Bouvet trip. We hope that Jorge will be able to join us on another adventure in the future. We look forward to that and thank him for his help thus far.

Harumi Kukita or Hal, JR4OZR, will be taking Jorge's place on the team. Hal has past DXpedition experience and is a well know and competitive contest operator. We welcome him to our team.

Antarctic Activity Week. The Worldwide Antarctic Program's (WAP) 14th Antarctic Activity Week (AAW) will take place between 20 and 26 February. The real purpose of the event is to foster interest in the Antarctic region/continent and its matters. Look for special event stations world-wide to be available for you to work. Each has its own super special QSL card available. Visit for the list of stations, QSL routes and attractive awards. As of press time, there were 37 stations listed to be on the air.

To commemorate the 14th International Antarctic Week, a very special Award will be issued to all Radio Amateurs worldwide who contact a number of the special event stations that will be active on the HF bands. The Special Diploma will be sent free of charge in PDF format to all participants that fulfil the required number of contacts on each category. For more information on the AAW, visit

Australia. Operators from the Darwin Amateur Radio Club will on air using the call sign VI8BOD from 18 February to 28 March to remember the 75th anniversary of the Japanese bombing of Darwin, Australia in 1942. The QSL Manager is M0URX and QSL cards can be requested on the M0URX OQRS. More information can be found by searching VI8BOD on

Bangladesh. Juris, YL2GM, will lead a team of operators to be active as S21GM and S21KW from Bangladesh between 15 and 27 March. The S21GM call sign will be used in the first half of their DXpedition, and S21KW during the second half. This is caused by the specifics of the regulations in Bangladesh and not because they want more duplicated QSOs in the log.

They state, "Please do not attempt to make QSOs with both of these call signs on the same bands and modes. Please treat both call signs as one, thus giving other fellow amateurs a better chance to make their QSO with us, potentially All Time New One (ATNO).". Activity will be on 160 to 10 meters using CW, SSB and RTTY. QSL via YL2GN, direct, by the Bureau, ClubLog's OQRS (for direct or Bureau) or e-mail requests via A full LoTW upload will be done in 3 months time after the end of their trip.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 19 February 2017 


VHF ACTIVITY IS INCREASING AROUND THE COUNTRY – VHF activity is increasing around the country. In Cape Town ZS1TAF has been running a net on 144,300 MHz SSB every Thursday evening for the past year or two. Recently the Coastal Radio Group operated a successful field station ZS1CRG on Piketberg Mountain for the first time during the PEARS VHF/UHF contest, and it was manned by ZS1DUP, ZS1HE, ZS1ABU and ZS1DWH. The West Coastal Group, which included ZS1CF and ZS1HO, often worked ZS3JPY at Kleinzee and as far north as V51LZ at Oranjemund. ZS3AG at Kimberley has often heard traces of signals from the group and has been copied by V51PJ. 

V51PJ has hooked up with stations as far afield as ZS2ACP and ZS2BK in Port Elizabeth, including ZS4A, ZS4TX, ZR6AUI and ZS6NK at Polokwane, either on Digital or Analogue. ZS6CBQ established a very successful net on 144,300 SSB some years ago on Saturday and Sunday mornings that covered Divisions 6 and 4. He has now added a new net on 432,200 MHz SSB during the same period. A Monday evening net run by ZS2ABF in East London with, ZS5DJ on 144,300 MHz SSB, has been joined by ZS5HV at Scottburgh, and ZS5LEE in Durban. It could later extend as far south as Port Elizabeth. Now that we are at the minimum Solar Cycle and DX on HF is declining, give VHF a try for a change, it is both a challenge and fun. So make an effort and join these VHF groups and help to advance VHF and amateur radio. 

NEW 432 MHz NET STARTED IN GAUTENG – Carl Minne, ZSCBQ, reported that the following stations were logged on 432,200 MHz SSB:


Saturday 11 Feb. 2017
ZS6BUN - 5/9+20
ZR6CMG - 5/9
ZS6KSG - 5/9+40
ZR6AUI - 5/7
ZS4A -5/4 (8 element Yagi - 236km)

Sunday 12 Feb. 2017
ZS6WAB - 5/9+20 (300 km)
ZR6CMG - 5/9 (Jaco also work ZS6WAB on back of his beam S2)
ZS6KSG - 5/9+40
ZS4A - 5/4

Carl says: “The 70cm group on 432.200 MHz is getting momentum and I hope to log many more stations over week-ends.” 

RESULTS OF PEARS NATIONAL VHF & UHF CONTEST WILL BE RELEASED NEXT WEEKEND – The reults of the recent PEARS National VHF & UHF Contest will be posted on the VHF Forum next weekend, and will also appear in the March issue of RADIO ZS. 

GIANT RADIO GALAXY DISCOVERED – An international team of astronomers reports the discovery of a new giant radio galaxy (GRG) associated with the galaxy triplet known as UGC 9555, and located some 820 million light years away from the Earth. The newly discovered galaxy turns out to be one of the largest GRGs so far detected, and has a projected linear size of 8,34 million light years. This makes it one of the largest GRGs known to date. Currently, with a projected size of approximately 16 million light years, the J1420-0545 holds the title of the largest giant radio galaxy discovered so far. (As a reference our Milky Way is only 100 000 light years across). 

Recently, a team of researchers at the Jodrell Bank Centre for Astrophysics in Manchester, U.K., has combed through the data provided by the Low Frequency Array (LOFAR) and uncovered new, important information about this distant disturbed galaxy group.


The team has analysed the data available in the LOFAR Multi frequency Snapshot Sky Survey (MSSS). It is the first northern-sky LOFAR imaging survey that covers the sky north of the celestial equator at frequencies from 119 to 158 MHz in eight separate 2.0 MHz bands. The images obtained as a part of the LOFAR MSSS allowed the scientists to distinguish the new giant radio galaxy.

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.
