ICASA COUNCIL APPROVES MOU WITH SARL This week the Council of ICASA approved the memorandum of understanding with the SARL. The memorandum replaces a very old MOU which was outdated and had expired. The purpose of the MOU is to establish the manner in which the Authority and the SARL will interact with each other to enable them, inter alia: 

  • to co-ordinate and harmonise the issuing of amateur radio frequency spectrum licences in South Africa;
  • to establish a framework to conduct the radio amateur examination (RAE); and, 
  • to co-ordinate activities with respect to matters of common interest

In terms of the MOU the SARL will set up a formal National Repeater and Beacon Managing Group in order to coordinate applications made for repeater and beacon station licences and a Joint Working Committee constituted by representatives of the Authority and the SARL, as nominated by the parties respectively, shall be established pursuant to this Agreement and shall function on an on-going basis. Arrangements are now being made by ICASA’s legal department for the formal signing of the MOU by SARL President and the Chairman of ICASA. The signed document will be made available on the SARL web pages. 

Commenting on the MOU, SARL President, Nico van Rensburg said that the signing of the MOU will be an important milestone as it formalise the relationship between ICASA and the SARL. 

Broadcasters, jammers wreak havoc on amateur radio frequencies

The ARRL reports the battle in the amateur radio 7 MHz band continues between Radio Eritrea and Radio Ethiopia, which is said to be jamming the Eritrean broadcaster with broadband white noise 

The problem for radio amateurs is that the battle is taking place in the 40 meter phone band — 7,145 and 7,175 MHz — with the jamming signal reported by the IARU Region 1 Monitoring System (IARUMS) to be 20 kHz wide on each channel. 

The on-air conflict has been going on for years; Ethiopia constructed new transmitting sites in 2008 and is said to use two or three of them for jamming purposes. The interfering signals can be heard in North America after dark.

According to IARUMS Region 1 Coordinator Wolf Hadel, DK2OM, Radio Eritrea is airing separate programs on each frequency. He said in the IARUMS September newsletter that telecommunications regulators in Germany, Austria and Switzerland have been informed, so they could file official complaints.

After not having a coordinator, and the job being done with only a month to go, a total of 51 stations were active over the weekend; up from only 8 last year. 16 Amateur Radio stations were in operation through the weekend, with a few Scout groups running their first JOTA event from their own halls.  Final numbers are coming in on the amount of participants, but Sandringham Scout Group held the largest event for the year with just over 230 Cubs, Scouts and Adults in attendance. Amateur Radio clubs and individual Hams assisted groups and districts to run their events. A full report back will be available in the November Radio ZS. Koos Fick, ZR6KF, SARL Youth coordinator gave a talk to the youth on Amateur Radio and Nico, ZS6QL, SARL President was in attendance to show support and answer any questions. Plenty interest from the youth on how to get licensed, which is a great step for the youth development within our great hobby.

Richard ZS6RKE, National JOTA JOTI Coordinator, Scouts South Africa expressed his thanks to all who assisted, and  said “I hope that next year we can get more Hams involved with the youth.”


IARU AC. The Administrative Council (AC) of the International Amateur Radio Union (IARU) is responsible for the policy and management of the IARU and consists of the three IARU international officers and two representatives from each of the three IARU regional organizations. The AC held its annual in-person meeting on 7 and 8 October in Vina del Mar (Chile), immediately prior to the IARU Region 2 Conference. See for the details.

AMSATSA SDR WORKSHOP: In association with the South African Radio League, AMSAT SA is holding a Software Defined Radio workshop at the NARC on Saturday 26 November 2016.  Get details and registration information here



On 20 September ICASA published a discussion document on Equipment Type Approval Exemption and has invited written representation with the closing date of 2 December 2016. Type approval is a very important issue for the amateur radio fraternity and has been on the agenda of the SARL/ICASA liaison committee for the past few years. Some two years ago the SARL submitted a document to ICASA asking that all amateur radio equipment, including homebrew equipment, be excluded from the regulations promulgated on 26 August 2013 which required that all radio equipment had to be type approved. The SARL will review its original proposals in terms of the ICASA discussion document, published last week. The SARL will also have preliminary discussions at the next SARL - ICASA liaison meeting scheduled for 17 October 2016. The Government Gazette is available on Radio amateurs are invited to provide input for review by the SARL Regulatory Working Group. Please send your input to by 31 October 2016.

DECEMBER IS YOTA MONTH - From Thursday 1 December to Saturday 31 December 2016, the annual Youngsters on the Air (YOTA) event takes place and YOTA stations will attempt to make many contacts worldwide with each other. This is an excellent opportunity to get young amateurs in their teens and early 20s to talk with their counterparts on the air 

This  is not a formal contest, but a way to get young people  on the air and to let them realize that there are hundreds of other peers around the world that feel just the same as they do about the hobby. The main aim is to get our youngsters on the air and for them to make contact with youngsters all over the world. This is an excellent opportunity for clubs to run a demonstration at a local school or church or to gather together with our amateur friends at the club and display this great hobby to our South African youth! 

The SARL  will once again register as a Region 1 Member Society participant and obtain the special call sign ZS9YOTA that will be registered as an educational call sign for use by clubs and individuals during December. Details pertaining to bookings for the special call sign will be made available during November. For any additional information or possible questions please forward your e-mails to Koos, ZR6KF, at or alternatively to Nico, ZS6QL, at They will provide you with much more information and will answer any questions.

NINE NEW RADIO AMATEURS - Cameron Eales ZS6CYE (photo insert) the President of the High School Jeugland  Radio Club - ZR6JRC is proud to announce that a group of 9 members passed the class B RAE last week Saturday after attending Saturday classes for a period of 10 weeks.

The high school youth club was founded in March 2016 and this is the first group to pass the class B RAE. Jeugland Radio Club is affiliated to the SARL and the club committee, in its entirety, consists of the youngster’s them-selves managing all activities. The group in no particular order are Nadia Fourie ZU6NF; Maryna Coetzer ZU6MC - Secretary; Tiaan Badenhorst ZU6BAD; Zhaques Labushagne ZU6ZJN; Ulrich Troskie ZU6ULI - Treasurer; Tiaan Harmse ZU6TRH; Cullen Bailey ZU6CUL – Vice-President; Dantè Eliott ZU6DJE and Dewald Harmse ZU6DRH. To the  nine new radio amateurs  welcome to the wonderful world of amateur radio. We wish them all the most enjoyable experiences in discovering all the various aspects of this great hobby and for the future that amateur radio can offer.

THE GEOMAGNETIC BLITZ OF SEPTEMBER 1941: Seventy-five years ago today, a massive geomagnetic storm disrupted electrical power, interrupted radio broadcasts, and illuminated the night sky in a World War II battle theater. The untold story of this remarkable event has just been published in a lively article by two space weather researchers.

ICASA RULES ABOUT ZU LICENSES FOR PEOPLE OVER 25 - From  2017 amateurs over 25 years old who hold a ZU license cannot renew their  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

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 23 October 2016 


SOLAR CYCLE 25 COULD BE ONE OF THE WEAKEST – According to NASA’s long range solar forecast Cycle 25, peaking around 2022, could be one of the weakest in centuries. This could be another Maunder Minimum, which will affect HF frequencies where the MUF could drop down to the lower frequencies. Do not despair because now is the time to start exploring the VHF bands on 50, 70 and 144 MHz, which you’ll find much more challenging than HF.  If you make the effort to build or acquire high gain horizontal Yagis for these bands, improve your equipment, learn about VHF propagation, then you could expect to make many long distance QSO’s. For example: Tropo Enhancement on 144 MHz could provide regular 400 km contacts, while Tropo Ducting could extend the range to many thousands of kilometres, especially across the sea. On 50 MHz a distance of 2500 km could be achieved on Meteor Scatter on both analogue and digital. There are many other modes possible on this Magic Band such as Sporadic-E, but all you have to do is to have the courage to experiment. If you are interested in worldwide DX then try EME that is possible almost daily and throughout the year, and not affected by ionospheric conditions. But please note you are not going to achieve much on VHF with a vertical antenna and QRP. VHF is very challenging indeed, but also much more exciting and rewarding.


THE CHIRP RADAR MODULATION – Ian Roberts, ZS6BTE, was in communication with Andrew Martin, VK3OE, who was involved with the Australian Chirp Radar System. This is his reply to Ian who posted it on the SARL Forum.


“The good thing about chirp is that it can be averaged for long periods of time. This is particularly so if the transmitter and receiver are GPS locked, in time for the chirp and in frequency for the RF parts. A 2 kHz chirp gives 36 dB gain in S/N per second, or 51 dB gain in S/N per minute of averaging. This is a very large gain so when added to the 500 Watts provides a very high system gain. The good thing about using chirp for tropo is that the tropo paths are relatively stable over a period of minutes to hours so averaging over long periods works very well. The current version of the SL chirp is also very good, and you can provide an input via the computer sound card for GPS time sync. For the generation of the chirp a step frequency is OK but the chirp increments must be very small, around 1 to 10 MHz per step, otherise the chirp correlator in the receiver starts to fall apart. The last thing is that if the system is time and frequency locked the range measurement will be very accurate, so that a receiver at 7000 km will show the distance as well as the amplitude, providing an excellent verification. The chirp can also be coded with a callsign but the SL does not have that capability at the moment, maybe a future option. The chirp is also a very robust modulation so detection is straight forward. Good luck and I hope you are able to advance this project. Andrew VK3OE/VK3OER.”


IS THE TEP SEASON OVER? – Paul Smit, ZS6NK, informs us about TEP. He says: “The TEP season seems to be broken now with the end of the cycle. A few very short and selective openings have occurred. 30 September ZS6BTE worked 4X and heard 5B4CY and 4X1SIX beacons from 15:50 to 16:12 UTC. 02 October ZS4TX/6 (KG47ur) worked SV, 9H, 9K and 4X from 16:30 to 17:02 UTC. Nothing heard in KG46rc.12 October ZS4TX/6 worked SV and I from 18:12 to 18:28 UTC. 73 Paul ZS6NK.”

THE UNIVERSE CONTAINS 2 TRILLION GALAXIES – Astronomers have long pondered how many galaxies might exist in the Universe – and the answer appears to be a staggering two trillion. The figure, obtained from Hubble Telescope images, has shocked scientists who estimated the number to be at least 10 times smaller. The finding wasn't easy to come by. An international team of scientists examined deep space images taken by the Hubble from over the past 20 years, and converted them into 3D pictures. From there, they measured the number of galaxies at different times in the history of the universe, going back more than 13 billion years – near the time of the Big Bang. The researchers, led by Christopher Conselice of the University of Nottingham, also used new mathematical models, which allowed them to infer the existence of galaxies which telescopes cannot observe. The team’s findings are detailed in the Astrophysical Journal. The researchers concluded that there is such an abundance of galaxies that every patch in the sky, in principle, contains part of a galaxy. However, starlight from the galaxies is invisible to the human eye and most modern telescopes, due to factors which reduce visible and ultraviolet light in the universe.

CONTEST NEWS WITH ZS6C Updated 13 September 2016 

South African Radio League VHF/UHF: Dates and Times: 10:00 UTC Saturday 17 September to 10:00 UTC Sunday 18 September 2016. The contest starts and ends at the beginning and end on the hour. Use time signals from a reliable source. Categories: Base Station, Field Station, Club / Multi operator station and 4 hour limited category.  Contacts: Contacts must be two-way. Stations shall give signal reports as well as their location as latitude and longitude or full six-digit Maidenhead Locator. Self-Spotting will be allowed, e.g. you may announce that you are calling CQ on 144,250 on a repeater frequency or on internet logger. The contact itself or any in-formation related to the contact must be unassisted. NO information can be send between stations to assist with completing the contact. See Blue Book for more details

Africa All Mode International DX Contest: The objective of this all mode contest is to stimulate contesting from Africa. Date: 12:00 UTC on Saturday 17 September to 12:00 UTC on Sunday 18 September 2016. Both single and multi-operator stations may operate for the entire 24-hour period. Modes: CW, RTTY and SSB. Contestants may elect to enter a single mode category or take part as a mixed-mode entrant. Mixed-mode entrants may work the same station once on each mode per band. Contest Exchange:The exchange is your RS(T) (not checked during the log checking process), followed by an incremental serial number commencing at “001”. Changing modes or bands does not necessitate different serial number ranges, i.e. the serial number simply progresses from “001” upwards sequentially as you log QSOs in any category, for single or multi-op efforts. A complete exchange, consisting of an RS(T) and serial number, must be logged for each QSO. See Blue Book for more details

CQ World-Wide DX RTTY Contest: Date: September 24-25: Time: 0000 GMT Saturday -- Ends 2400 GMT Sunday. OBJECTIVE: For amateurs around the world to contact as many other amateurs in as many CQ zones, countries, and W/VE QTHs as possible. BANDS: Five bands only: 3.5, 7, 14, 21 and 28 MHz. Observance of established band plans is strongly encouraged. CONTEST EXCHANGE: RST report plus CQ zone number of the station location (e.g., 599 14). Stations in the continental USA and Canada also send QTH (e.g., 599 05 MA).

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.
