ZS85VT - The Voortrekker movement celebrates its 85th birthday in 2016 and the call sign ZS85VT is used during special events. Thank  you to every radio amateur who took the time to support the enthusiastic young people. We also thank every Voortrekker group, camp or activity that made time for amateur radio during their programme for CQ Hou koers. Twenty stations  participated on 15 October. Will you be taking part in CQ Hou Koers 2017 and offer your help to your local Voortrekker group or radio club? Visit to find our more about the Voortrekker movement. Enquiries related to CQ Hou Koers may be sent to


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.”

Change in IARU Secretary

Rod Stafford, W6ROD, has retired as IARU Secretary after seven years of service in that position. The IARU Constitution provides that the member-society serving as the International Secretariat, i.e. the ARRL, shall designate the Secretary. The ARRL Board of Directors has designated David Sumner, K1ZZ, to replace Mr Stafford as Secretary effective 15 October 2016.

David Sumner has served in this capacity twice previously, from 1982 to 1989 and from 1999 to 2009, while employed by the ARRL to manage its headquarters. Now retired from employment, he joins the other IARU officers and Administrative Council members in serving as a volunteer.

IARU President Tim Ellam, VE6SH, has appointed Rod Stafford as Emergency Communications Special Advisor. In this capacity, he will represent the interests of the IARU and the global amateur radio community in the Development Sector of the ITU and will offer advice and counsel on matters relating to emergency and disaster response communications.

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 

HF Update with Dennis, ZS4BS (updated 15 October 2016)

SOTA Summit to Summit Event. 22 October will see an increase in Summits on the Air activity between Europe and Australasia. As has been the case for the last few years, a special event is being organised by Andrew, VK1AD, and Mike, 2E0YY, to coincide with improving radio propagation conditions.

            This "S2S" (Summit to Summit) 'all mode' CW, SSB, Data and even FM event already has commitments from Australia, New Zealand, England, Scotland, Germany and Austria with other European stations expected to join in the climb to the top of mountains in each region. These "activators" aim to make as many "S2S" contacts as possible with other amateurs on SOTA summits in Europe and Australasia.

            The timing will be from 06:30 UTC for about two hours and is planned to coincide with long path propagation between Europe and down under. Around the same time, short path communications between Europe and North America is often possible. So if some willing SOTA activators in North America could listen out from a night-time accessible SOTA summit, this activity has the chance to create a World-Wide Summit to Summit event this year.

            Most stations will be running low power with simple omni-directional antennas so this event also aims to show just what can be achieved with limited equipment from a location with a low noise floor.

UKEICC. The UK/EI DX SSB Contest will be held from 12:00 UTC on 22 October until 12:00 UTC on 23 October. See for complete details.

QSL VK9NZ. The OQRS for direct and bureau QSL requests for the recent activity from Norfolk Island is up and running on Club Log. For any log queries, please contact Paul, ZL4TT ( The log will be corrected and uploaded to LoTW in approximately two weeks.

Cuba, CO. CO8DM, CO8ZZ, K1EP, K1MM, VE3AXC, VE3XIN and W2DLT will be active as T48K from Cuba between 26 and 30 October, including an entry in the CQ WW DX SSB Contest. QSL direct to DK1WI.

Vietnam, 3W. Mike, N0ODK plans to operate as 3W2DK between 15 October and 5 November including the CQ WW DX SSB Contest. He will be active on 40 to 10 m on SSB and some digital modes. QSL via N0ODK (d/B), LoTW.

Poland, SP. SN4KIDS aims to support the charity initiative Hams4KIDS, which wants to raise funds in support of UNICEF's effort to fight malnutrition among children. The call will be used between 14 October and 13 November. Each QSO raises 2 cents for charity. QSL via ClubLog OQRS and visit for more information.

Austria, OE. OE30EUDXF, operated by Joe, OE4VIE, celebrates the 30th anniversary of the European DX Foundation and will be active until 31 December. QSL via OE4VIE (d/B).

Belgium, ON. ON35CLM commemorates the liberation of the town Knokke by Canadian forces in November 1944. The call will be active between 15 October and 14 November. QSL via ON3AIM.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 16 October 2016 


METEOR SCATTER COMMUNICATION – There are 88 meteor showers present throughout the year, while about ten are major showers and all the rest are minor showers. The stronger meteor showers can provide VHF contacts up to 2500 km on 50 MHz or 70 MHz SSB or digital. Next week the Orionids meteor shower will peak on Thursday night 20 October until early morning on Friday 21 October 2016 when about 20 meteor trails will be visible per hour. A meteor burst that provides about 30 seconds of communication on 50 MHz will last only 3 seconds on 144 MHz and about a second on 432 MHz, but digital communication is still possible on these bands. On rare occasions a meteor burst could last up to three minutes on 50 MHz. The Orionids meteor shower will be followed by peak periods of the Leonids on 17 November, the Geminids on 14 December 2016, and the Quadrantids on 4 January 2017. The visual rate for the Leonids will be around 20 trails per hour, whereas the Geminids will peak at 120 per hour followed by the Quadrantids at 100 per hour. 

144 MHz NEWS – Jaco Cronje reported from Pretoria: “Last night, Tuesday 11 October, the following stations were active from Rayton, Pretoria, Krugersdorp and Kempton Park on 144,300 MHz SSB. They were Kallie ZS6KCS, Erens ZS6EFG, Jaco ZR6CMG, Carl ZR6CBQ and Ronnie ZS6BSB. Hope to hear a lot more stations on Thursday night 13 October 2016 around 19:30 CAT. 73 Jaco ZR6CMG.”  

REVIVING ACTIVITY ON 70 MHz – James Bestbier, ZS1XN, asked the following question: “I have gotten hold of an old Neutec Ranger 25 Watt FM transceiver, which could probably be converted to 70 MHz. Last I looked into this 70 MHz was still being used by by commercial stations around Cape Town. There seems to be no amateur activity and I wonder if there is a point in doing the conversion? Can someone suggest frequencies? The Ranger has 16 channels.” 

Here is a reply from Pieter Jacobs, V51PJ: “Do the reprogramming of the frequencies we are allowed to operate on. Get a Yagi and homebrew it, (DK7ZB has good designs) and then add the connections needed to do digital modes, and you can start testing on 4 metres long distance using Tropo or Meteor Scatter. Christo ZR6AUI has done it with great success.”  

A comment from ZS2FM: “The frequency range of this band covers 70,000 to 70,300 MHz and Icasa now permits maximum power of 400 Watts. The most frequently used channel on the 4 metre band is 70,200 MHz FM, so get it programmed for every 25 kHz channel, this applies to ex-commercial transceivers such as Neutec Ranger, Midland, Astra etc. If you wish to work long distances then you will have to acquire a horizontal Yagi. There is also a regular net operating from Port Elizabeth on 70,200 MHz FM on Monday evenings from 19:00 CAT using simliar type of equipment. The forthcoming PEARS VHF/UHF contest covers this frequency on FM. 

MICROWAVE NEWS – New 10GHz Tropo Ducting World Record: in January 2016 Derek Zeck, VK6DZ, near Peaceful Bay established a two-way contact on 10 GHz JT4f with Rex Moncur, VK7MO in Tasmania. This is an extention of their previous record to 2793 km via Tropo Ducting. VK7MO used 50 Watts to a 77 cm dish, and VK6DZ ran 10 Watts to a 60 cm dish.

UK Record on 134 GHz broken: John G8ACE and Ian G8KQW extended the UK record on 134 GHz to 35,6 km over a LOS path. Transmitters: DBES105A diode x4 multiplier driven with 100 mW at 33,6 GHz, Receivers: Quad diode package driven at one sixth frequency i.e. ~23 GHz, and IF on 145 MHz. Antennas were 30 cm Cassegrain dishes.

First-ever 241 GHz QSO in UK: On 16 February 2016 Roger G8CUB completed a CW contact with with Chris G0FDZ on 241 GHz (1,2 cm) over a distance of 30 metres. Transmitters based on Elcom synthesisers and G0FDZ’s receive LO, and G8CUB using a 16,0835 GHz synthesisiser as LO (X15) into a Textronix mixer on receive. Both stations used separate Cassegrain dishes with diameters of 25 cm and 30 cm, respectively. 

THE QRA64 DIGITAL MODE WAS USED DURING THE TRANSATLANTIC TESTS –  QRA64 is intended for EME and other weak-signal use.  Its internal code was designed by Nico Palermo, IV3NWV, and implemented in WSJT-X by K1JT.  The protocol uses a "Q-ary Repeat Accumulate" (QRA) code, another one of the latest research areas in communication theory.  The QRA64 code is inherently better than the Reed Solomon (63,12) code used in JT65, yielding already a 1.3 dB advantage.  QRA64 uses a new synchronizing scheme based on a 7 x 7 Costas array, so you will not see a bright sync tone at the lowest tone frequency.  This change yields another 1.9 dB advantage.  

In most respects our implementation of QRA64 is operationally similar to JT65.  QRA64 does not use two-tone shorthand messages, and it makes no use of a call sign database.  Rather, additional sensitivity is gained by making use of "already known" information as a QSO progresses -- for example, when reports are being exchanged and you have already decoded both call signs in a previous transmission.  QRA64 presently offers no message averaging capability, though that may be added.  In our early tests, many EME QSOs have already been made using sub-modes QRA64A-E on bands from 144 MHz to 10 GHz. 

NEW TYPE OF FEEDHORN DESIGNED BY SWEDEN FOR THE SKA – This sensitive feed horn with an opening almost one metre across, and weighing almost 100 kilograms was built at Onsala Space Observatory and has been delivered in Canada, and will now be tested on one of the antenna prototypes built for SKA at the Canadian National Research Council’s Dominion Radio Astrophysical Observatory (DRAO) facility near Penticton, British Columbia, Canada. Similar feed horns will eventually be fitted on each of the 133 dish antennas at the SKA’s South African site in the first phase of deployment of the SKA.

The feed horn has been developed for the SKA Band 1, the longest wavelengths that SKA’s dish antennas will be sensitive to, between 350 MHz and 1050 MHz (wavelengths from 30-85 cm). The amplifier uses nanotechnology to amplify the very weak radio waves with as little noise as possible. Normally, noise reduction means to cool the amplifier down to a few degrees above absolute zero. Instead, this amplifier is integrated directly in the feed horn, which means it can retain the telescope’s sensitivity without using any cooling at all. This will provide a great saving in cost for the SKA project.

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.
