ITU officially confirms: Z6 prefix is illegal

In a repost by YT9TP (Serbia) it would appear that the International Telecommunication Union has officially confirmed use of the Z6 prefix is illegal. This from ITU Operational Bulletin No. 1149 dated 1 June 2018.

“Call sign series can be allocated only to the administrations of the ITU Member States by world radio communication conferences or, between radio communication conferences, by the ITU Secretary-General. In this respect, the attention of the ITU administrations is drawn to the fact that ITU has not allocated call sign series Z6 to any of its Member States. Consequently, the utilization of call signs series Z6 by any entity without a formal allocation and consent of the ITU represents an unauthorized and illegal usage of this international numbering resource.”

Current Regulations remain in force- The publication of the National Radio Frequency band plan has created some confusion and a lot of speculation. Here are the facts:

The current regulations remain in force. The frequencies and conditions as published in Annexure I of the 2015 Radio Frequency Spectrum Regulations remain in force.  View  list of amateur radio frequencies here.

ICASA has started a process to amend the regulations and bring them in line with the National Frequency Band Plan. A draft will be published in the Government Gazette in due course for comment. Although ICASA Councillor, Peter Zimri, told the SARL that ICASA is fast tracking the new regulations, it will likely be some months before the draft is gazetted for comment. The SARL will monitor the situation.

As far as the 5 MHz is concerned, the allocation is not in the current addendum I. However ICASA agreed that all radio licensed amateurs ZR, ZS and ZU may use the frequencies provided they operate with the maximum power of 15 watts eirp. The SARL has made representation to ICASA to consider a limit of 20 dBW, or 100 watts. This process will mostly likely only be considered after the draft regulations are published for comment.  There is currently no band plan. Before a band plan for South Africa is considered research should be undertaken what other countries that have 100 kHz of the 5MHz have agreed on.  In some countries additional spot frequencies outside the WRC allocation have been allocated to the amateur service. These should also be considered as they could present some DX opportunities 

If you have views on a band plan please send them to so that an informed recommendation can be made to Council and ultimately  voted on electronically. 60 Metre Allocations World-wide

Radio ZS June 2018 - The June 2018 issue of Radio ZS is available for download - all 52 pages! Only 597 copies of the May 2018 Radio ZS were downloaded.

SOUTH AFRICA GETS 100 KHZ ON 60 METRES - On Friday 25 May, ICASA published the National Radio Frequency Plan 2018 in which amateur radio was allocated 100 kHz on a shared basis in the 60-metre band as well as channel 5 290 kHz for the 5 MHz propagation research project. The National Radio Frequency Plan 2018 is a nearly 300-page document which covers the entire radio frequency spectrum.  

The spectrum 5 350 to 5 450 kHz is now available to all licensed radio amateurs on a shared non-interference basis.  In addition, the channel 5 290 kHz has been allocated for WSPR beacons deployed in the SARL Propagation Research project and members can continue to use this frequency. Due to licensing issues the SARL has kept low key on the 5 290 kHz beacon project. "We now can go full steam ahead", Hans van de Groenendaal, ZS6AKV, the SARL Regulatory Manager said. "There are no longer any restrictions and no application for use of the 60-metre band is required."

Commenting on the 100 kHz 60 metre allocation, SARL President, Nico van Rensburg ZS6QL said that the SARL has worked on this for a long time. "Clearly our persistent interaction with ICASA has paid dividends. This is however not the end of the road as in the new band plan power on 5 MHz is restricted to the WRC-15 agreement of 15 watts e.i.r.p

BAD OPERATING PRACTICES ON HF - Following a recent communicated trend of on air abuse including misconduct on 20 m, the Namibian Amateur Radio League (NARL) President Werner, V51JP and the SARL President Nico, ZS6QL engaged with the respective individuals and were able to resolve the matter. Unfortunately, this did not end there, we are currently facing a situation where South African radio amateurs are now themselves guilty of misconduct on the air.

Amateur radio is a self-governing service and we as respected amateurs operate in accordance with a code of conduct which stand for cooperation, assistance, loyalty, good-will, patience, consideration and friendship when operating on the air.

The SARL Council would like to appeal to South African amateurs to refrain from bad behaviour and poor operating practices. Please promote fair play and adhere to the amateur code of conduct on the air in the spirit of amateur radio.


Young South African Radio Amateurs invited to apply for YOTA 2018 - South Africa will host 80 young Radio Amateurs from 34 countries in Europe, Africa and parts of the Middle East, for a week-long international event from 8 – 15 August 2018. This is the first time that YOTA (Youngsters–on–the–Air Summer Event) is presented in South Africa and hosted by the South African Radio League (SARL).  

Applications are now invited for the South African Team and anyone aged between 16 and 25 is invited to apply for selection as a team member and participate in this amazing amateur radio event.

“This annual event creates, in addition to amateur radio, the opportunity to learn about different nationalities and cultures, foster international friendships and goodwill as well as learning new radio communication and technical skills”, says SARL president, Nico van Rensburg. YOTA brings together young radio amateurs under the age of 26 who have a passion for amateur radio and technology to learn new skills, discuss and share ideas about amateur radio and its future. This year’s camp will not just focus on teaching individual skills but look at empowering the group to become mentors and transfer the skills they have learned. 

The week long programme includes building a radio transceiver kit, becoming involved in launching and tracking of a high altitude balloon with various radio equipment on-board, hone their communication skills using multi frequency amateur radio stations and other technology and communications based activities. 

To be considered for selection in the South African team visit,   complete the online application in full and submit before 30 May 2018. The SARL YOTA Team Selection Committee will notify successful applicants by 17 June 2018. Full details about the 2018 event can be found on For additional information contact the team at

Focus on VHF 17 June 2018

For a audio version click here  

In this week’s tutorial we will be looking at how to use FT8  

Let us first start at the beginning. What do you need to get started with the digital modes? 

You need a PC with either a sound card or a USB port. This is the minimum needed to be able to start. For the amateurs who want to home-brew you can look on the internet for circuit diagrams to build own sound card to radio interface. Alternatively you can buy a USB sound card interface such as the SIGNALINK USB Interface. It is supplied with the proper connectors to easily connect to the radio that you want to use. The USB sound drivers are supported by Windows software.

Next you need to download the various digital mode software packages from the internet such as FLDIGI and WSJT-X. WSJT-X was discussed in a previous tutorial. These packages cover all digital modes that are being used. You can GOOGLE the names and you will find the download sites.

The latest versions also support full CAT control. CAT control or Computer Aided Transceiver control is when the PC will change the frequency etc. for each mode selected and also controls the logging software if enabled. We will discuss sound cards and rig control in a later tutorial. 

Some say FT8 is a computer to computer mode, but human intervention is still there. You must start the QSO and then yes it is sort of automatic from there on.  

Let’s look at the QSO sequence as this is very important for a valid QSO on any digital mode.  

First you need to give your call sign and of course the station you are calling, or if you are just listening and watching the decode screen you can double click on the station calling “CQ Call sign Grid”. This will automatically store the Call sign calling CQ in the DX Call block on your program and it will generate the correct messages to be sent. When the calling station is answering your call he will answer you with your call sign his call sign and a signal report. This signal report is the level of the first decoded signal from you. In digital mode the first signal level decoded is always the one used even if it does get better or worse during the QSO. Now your response to his answer will be in TX3 which is line 3 of the generated messages. When he receives your line 3 which is his call sign your call sign and a R with the signal report of the level you received him first. This is to confirm with him that you did receive his line 2 with signal report and that you now give him his signal report. Now the station in QSO with you will send his line 4 or TX4 to you which contains your call sign his call sign and RRR. The RRR is to confirm that he did receive your signal report as well. The call is now valid and the only message left to send is TX5 or line 5 with his call sign your call sign and 73. A lot of chasers do not say 73 as they want to get as many calls done as possible, especially during DX-Peditions. With DX-Peditions you do not send TX5. Once you have received his TX4, you log the call as the DX-Pedition station will start calling CQ Call sign and Grid once done. 

Now what is the difference between DX-Pedition and normal operation? DX-Peditions want the maximum amount of calls logged as the whole world are calling them and conditions might fade quickly.

When there is a DX-Pedition operating the tip is to select in your software File>Settings>Advanced and click HOUND. They will be selecting FOX on their side. By selecting FOX on their side they automatically are able to add up to 5 stations in the message list – thus the computer is now working 5 stations at a single time. Once a TX4 is sent to a station it immediately opens up a space for the next call sign to be added. This feature provides a more stable flow of calls being worked than trying to work through the chaos on the waterfall manually. They actually transmit on 5 different audio frequencies that change continually. They can change this to fewer stations if conditions are not favourable. 

Another feature they have is to then adjust what signal levels they want to decode. If you are adding your 1KW linear to the output they will not even see you as the software will just blank you out on their screen. You will also be getting a bad name as everything is reported automatically on the worldwide logbooks that are being used because you are blocking other stations that want to work them.

Now how do you make sure you do not splatter or give out a bad signal? When you transmit the most important level to monitor is your ALC or Automatic Level Control. If your radio does not have an ALC meter, then you need to monitor your output power. Remember digital modes are low power modes. Not high power modes.

The set-up procedure is as follows. Generate a signal. Look at your ALC meter. Adjust the audio output level of the sound card so that the ALC just moves. Alternatively look at your output power and adjust the audio output level so that the power output level just drops. Now you are guaranteed to have a good clean transmission. You normally set your receive level for 40-50 dB which is in the middle of the receive level indicator on the PC screen. You are now ready to operate any digital mode and be sure of a clean decodable signal. Again stick to low output power.  

In next week’s tutorial we will discuss a little more about sound cards and rig control, followed by digital modes and timing.  

And now onto some VHF and UHF news...

 Locally, earlier this week Willem ZS6WAB queried on the SARL Forum whether anyone was still using his beacons. Willem has since switched off his 4m, 2m and 70cm beacons. Carl, ZS6CBQ also responded to Willem and said that activity north of Pretoria was non-existent and that they could not contact Servaas ZS6SER either.  

Carl reported that the Free State guys were however active and that there is much more activity than only weekend activity now. They now have a group every night from 20:00 to 21:00 and every morning from 06:00 till 07:00 active on 144.300 MHz, mostly south from his QTH in Krugersdorp.

After a period of poor conditions the band has been wide open since Tuesday evening. On Thursday night signal reports were mostly 5/9+ 15 to 20 between most of the stations over average distances of 200 km. Carl worked Michael ZR4MF in Bloemfontein signal strength S7. Aircraft scatter and pre-amps were not necessary.

Carl says, we also tried 70cm on 432.200 MHz and signals were just as good. A quick test between Rickus ZS4A and myself on 23cm 1296.200 MHz was not good.

Carl also said that he has received some video clips from Dries ZS4AJ showing progress with his tower at his new QTH in Bloemfontein, and that he is sure that there will be many VHF and UHF QSO’s with him soon.
Vernon ZS6AIG has a lot of new VHF and UHF equipment in his radio room. His new Icom 9100 is getting a 23cm module, while the amplifier and Yagi is waiting to be fired up on 1296.200 MHz.
Dick ZS6BUN is also making good progress with his new tower on his farm.

So come and listen on 144.300 MHz SSB if you have a horizontal Yagi and give long distance contacts a go. 

Down in the Eastern Cape, Peter ZS2ABF reported that communications along the South East Coast was also difficult. Last Sunday, he and Dave ZS5DJ had a contact lasting a couple of minutes, but it was very poor. He tried again later in the week, but nothing was heard. Peter said that he would continue to try as one never knows when an opening will occur as the predictions were often wrong.

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.
