SARL Today HF Update with ZS4BS VHF/UHF News with Mike Bosch ZS2FM Contest News with Geoff ZS6C SARL Forum current topics Commercial Hamads


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.

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.

Jamboree on the Air 15 – 17 October - Richard Hooper, ZS6RKE is the newly appointed National JOTA JOTI Coordinator for SCOUTS South Africa. JOTA (Jamboree on the Air) is in its 59th Year, and amateurs and Clubs are needed  to assist with setting up HF stations for either a day or the full weekend for Scout Groups around the country. This great annual event takes place on the 15 - 17 Oct 2016 which really increases youth interest in our hobby. Please contact Richard, ZS6RKE at or on 0828015006 for all related information including a list of Scout groups in your area. 

 OCTOBER RADIO ZS - What is wrong with the Off-Centre-Fed-Dipole? Why the 16,2 m wire antenna? Why fifty ohms? These are three questions asked and answered in the October 2016 issue of Radio ZS.

The Sandringham Scout Group tells us more about their Field Day weekend. What did other Clubs do for Field Day?

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

Myanmar, XZ. The IOTA DXpedition to Myanmar, which was delayed until after the summer has to be postponed. “There were elections in Myanmar in November 2015 and we had to resubmit all our documentation,” the team says. "The new administration has now been selected but they need time to have new rules established. All domestic logistics are in place through our local Myanmar contact. He is also in weekly contact with three different ministerial departments and has indicated to us that the first weeks of February 2017 seem to be a good time slot for our DXpedition. We cannot push harder. We must be patient.”

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 25 September 201618 


MICROWAVE EXPERIMENTS – If you are interested in conducting experiments on Microwaves in the SHF or EHF spectrum then you can do it at low cost. Gallium Arsenide Gunn diode oscillators cover 10 – 200 GHz, while the Galium Nitride Gunn oscillators operate as high as 3 Terahertz. You could construct a Gunnplexer comprising a combination of a Gunn diode microwave oscillator, a microwave diode mixer, an audio amplifier with microphone, and a wideband FM receiver. With a DSTV dish you could make some distant FM contacts on 10 GHz (3 cm) from a high site via Line-of-Sight (LOS) or via Tropo propagation. If you would like to listen for EME signals on 10 GHz then try a DSTV dish with LNB and monitor the IF frequency. 

EARLY REPORTS ON SARL VHF/UHF CONTEST – Carl Minne, ZS6CBQ says: “I also want to thank everyone who made an effort to give points. A special thanks to Jaco ZR6CMG for getting the guys in Pretoria active over the past few months, it shows in the amount of contacts I made in that area. I worked 26 stations on 2M FM and a total of 52 stations on 2M. On 70cm I worked 23 stations, much more that previous contests. 23cm was quiet only 2 stations, but I found some stations with equipment for this band but the guys need antennas some work can be done here. My 6M Yagi was faulty and bad weather prevented me to fix the problem. We received about 4 logs so far so it looks like the new logs sheets are working very well. Thanks Pierre ZS6PJH. Bad planning caused that another HF contest was on the same dates as the VHF/UHF contest. 

“Pieter Jacobs, V51PJ, reports from Rosh Pinah: “The SARL VHF/UHF competition went real well. Activity was there and I managed to work 10 calls covering 6, 4 and 2 metres. I also worked Pine ZS6OB and Christo ZR6AUI on 2m MS with plenty pf pings. The MS pings were alive the whole Saturday afternoon and at nighttime it just disapeared. Sunday morning lots of Tropo while doing MS with div 6, 4 and 2, but Tropo Scatter were not for real QSO. Maximum meteor bursts at times about 20-25 seconds with very deep QSB but digital managed to pull it through. Signals on 6m were so strong that i followed MS QSO's with a HF antenna wrongly connected to the 6m port. Yes we are all making mistakes. 

  “I did it at last managed to work all ZS divisions 1 – 6 on 2 metres. That is a real first for V51 I think. All the years I only needed ZS5. After many tries with ZS5LEE and co I managed to work Lee via EME. By this he got his 80th DXCC on EME and I got my last division for 2 metres! So yes i feel real proud to do that as a VHFer. De V51PJ.” 

TRANSATLANTIC NEWS – Conditions suddenly picked up between PY and V51/ZS, Also towards Bruce ZD7VC whom I have sent an SMS to listen out for any signal on 144,250 MHz USB. Unfortunately he does not have any digital that side. Marcus in Brazil installed a 24 element Yagi with a preamp. Koos ZS3jJPY managed to raise the height of his antennas too, so he will also listen for signals at his QTH at Kleinzee. So yes all back on track again. Will do tests non-stop this side while conditions are there in case there is an opening to St. Helena Island as well. Greetings from the Namib de Pieter Jacobs, V51PJ.” 

THE UNIVERSE IS UNIFORM – Scientists from University College London and Imperial College London have put this assumption through its most stringent test yet and found only a 1 in 121,000 chance that the universe is not the same in all directions. To do this, they used maps of the Cosmic Microwave Background (CMB) radiation: the oldest light in the universe created shortly after the Big Bang. The maps were produced using measurements of the CMB taken between 2009 and 2013 by the European Space Agency's Planck satellite, providing a picture of the intensity and, for the first time, polarisation (in essence, the orientation) of the CMB across the whole sky. Looking out into the night sky, we see a clumpy universe: planets orbit stars in solar systems and stars are grouped into galaxies, which in turn form enormous galaxy clusters. But cosmologists assume this effect is only local: that if we look on sufficiently large scales, the universe is actually uniform.

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.
