2016 ARRL Handbook  is now available - The SA Amateur Radio Development Trust online bookstore has the 2016 ARRL Handbook in stock. Also amongst new arrivals is the McGraw Hill Arduino Projects for Amateur Radio. Visit for details and an orderform 


 ARiA Frequency Counter kit now available - The SARL ARiA frequency counter kit is now available by mail order or collection from the National Amateur Radio centre. There are two mail order options, via Postnet or post office small parcel service with tracking number.

The frequency counter exhibits several interesting features, like a maximum working frequency above 40 MHz, a 10 Hz resolution, low consumption (15 mA) and is easy to build. It is the ideal weekend project. The design is simple, given that most of the functions are implemented by the microprocessor which is supplied pre-programmed. For those who want to use the basic unit above the normal HF frequencies space for a  pre-scalar IC circuit is on  the PCB layout and in the schematic layout. This IC is not included in the basic kit can be order at an additional cost. This kit is ideal to meet the requirements of the amateur radio regulations which require that every amateur has a reliable method of measuring the transmit frequency.  Get the orderform here  

Special for SARL members - order before 23 March  and get an additional discount of 10%  

 New 5 MHz allocation for amateur radio agreed  at WRC15- New allocation for amateur radio service in the frequency band 5351.5 - 5366.5 kHz will maintain stable communications over various distances, especially for use when providing communications in disaster situations and for relief operations.  The South African Radio League has worked closely with ICASA and carried out propagation studies on two frequencies licensed by ICASA for this purpose.

It is not clear when the new allocation will be made available an replace the two frequencies that ICASA  allocated to members of the SARL. The current two licensed frequencies are 5260 and 5290 KHz .  


ICASA RULES ABOUT ZU LICENSES FOR PEOPLE OVER 25With the publication of the new radio regulations earlier this year, the much talked about age restriction for ZU license holders was implemented. 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).


HF UPDATE WITH ZS4BS (updated15 May 2016) 

DXCC News. 5A1AL (Libya, all operations) has been approved for DXCC credit. If you have had this rejected in a prior application, you can send a note to  to be placed on the list for an update to your record. Please note the submission date and/or reference number where the rejection was noted to expedite recovery of the information.

OTH Radars, Fishery and Taxi Traffic, Buoys, and Broadcasters Continue to Mar Ham Bands. The International Amateur Radio Union Region 1 Monitoring System (IARUMS) April newsletter chronicles a plethora of intruding signals heard on exclusive Amateur Radio allocations in Europe and Africa, many of these also affecting the bands in IARU Regions 1 and 3. The most significant interfering signals originate from over-the-horizon (OTH) radars in China and Russia and affect 40, 30, 20 and 15 metres. 

The newsletter also recounts monitoring stations' reports of voice traffic on several bands from fishing operations in various parts of the world, telemetry from marine buoys and persistent taxi dispatching traffic from Russia on 10 metres. Other interference has stemmed from broadcasters - harmonic-challenged and otherwise - as well as from jamming signals attempting to prevent broadcasts from reaching their intended audiences. Pirate (i.e., unlicensed) stations have been reported on 80 metres and elsewhere and Russian digital military traffic has been monitored on 40 and 20 metres. 

OTH radar interference prevails, however. IARUMS Region 1 Coordinator Wolf Hadel, DK2OM, documented Chinese OTH radar occupying considerable swaths of spectrum on several bands. 

Ocean Floater - ZL1SIX. The radio amateurs down under are about to launch a marine buoy into the South Pacific Ocean. The payload contains a low power JT9 beacon transmitting in the 30 m band. The beacon is already underway to the launch site and the beacon is already alive. Tracking the progress should be most interesting; we might learn a few things about sea currents and propagation. 

Norfolk Island. The Wireless Institute of Australia's Annual General Meeting will take place from 27 to 29 May on Norfolk Island. Expect VI9ANZAC, VK9PC (QSL via VK3PC) and VK9WI (QSL via VK3PC) to be active before, during and after the event.

Tim, NL8F, will be active as VK9NF from Norfolk Island from 24 May to 3 June. He will operate PSK, RTTY and SSB with a focus on 17 and 12 metres. QSL via K8NA. 


Lord Howe Island. Merv, N6NO will be celebrating his 80th birthday by returning to Lord Howe Island (OC-004) between 21 and 29 May. He will run 100 watts into a vertical dipole and will be active as VK9OL on 40 to 10 metres with a focus on CW and the WARC bands. QSL via N6NO, direct or bureau, and LoTW.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 29 May 2016 


IF YOU ARE STUCK WITH A VERTICAL ANTENNA THEN ADD A HORIZONTAL LOOP – Many Hams who are townhouse dwellers are often restricted to a vertical antenna on 144 MHz and limited to repeater and mobile operation. RCA has proven many years ago that horizontal VHF radio waves travel much further and with less loss over the curvature of the Earth than vertical waves. So if you could mount a small loop antenna (or 1/2 wavelength halo) at the bottom of your vertical then you could really extend the range of your 2 metre activities and make the best of both polarizations. 

All the long distance ZR/ZS stations including the VHF DX are all horizontally polarized and located at the bottom end of the 144 MHz band as well as all the beacons. A small loop antenna with a diameter of about 30 centimetres and fed with a gamma match could be mounted on the side of your metal mast. Alternatively if your vertical is mounted on a length of PVC pipe above a metal mast then the loop can be located around this pipe and will look less conspicuous. Full details of VHF loop antennas are available on the Internet or Amateur Radio Handbooks. You could stack two loop antennas above each other and realize a gain of 3 dBd or 5,15 dBi in most directions on 144 MHz. 

TRANSATLANTIC TESTS ON 144 MHz – Marcos Turbo, PY1MHZ, at Rio de Janeiro reports that he will be on vacation in August for 30 days and in January 30 days more. He will make Transatlantic attempts from his other QTH near the sea at locator GG98ma, and is working on a new rope ladder type long Yagi antenna. He is currently monitoring the V51VHF beacon as well as fellow Pieter V51PJ on 144,300 MHz JT65b using 2x12 LFA Yagis. Marcos is also running a beacon from his home QTH in Rio de Janeiro GG98ic: PY1ESP/b on 144,290 MHz CW and it is horizontally polarized. Keep a lookout for it. 

CRAIG SMITH, ZS5AV, IS COMING BACK ON VHF SOON –  Craig Smith, ZS5AV, who was a keen VHF-er disappeared off the VHF map for many years. He informed us that he is coming back and explained his absence, he says that he experienced two heart attacks, a bypass, a stroke and in April a pacemaker. His HF rigs need to go to the garage for fixing, after 20 years off the air! He is planning to make a 4 x12 LFA Yagis (G0KSC design) on 7,1 metre boom and hoping to get about 17 dBd gain from the array on 144 MHz. Bob ZS5CU gave him a QQE 0640 amplifier, which needed a bit of fixing and can run about 100 Watts. On 50 MHz he will use 2 x 6 el Yagis on a 7,2 (G0KSC type) with a gain of 12,8 dBd, but is equipped with a QQE 0640 amplifier with an output of about 90 Watts. 

He was reading some old Radio ZS magazines and was thinking about 4-400 amplifier for 6 metres and has a FT-690 to drive it, and he would love to have some serious power for 2 and 6 metres. In the old days from Durban he worked Van ZS5LW in Germiston, Willie ZS2OW from Komgha, his best was Hal ZS6WB at Pretoria on 2 metres, also Bloemfontein, Welkom and Harrismith using 350 Watts on a single 13 element Yagi and no pre-amp. Craig says he has a lot to be sorted out like getting his tower and antennas up and will then make some noise. He says that all we need are more VHF stations on the air! 


L. Jordan ZS1LG asks the question: “I want to know if there is anybody on 4 metres in Cape Town. I was cleaning out the shack over the weekend and stumbled across a Anytone 4 metre rig."

Wouter ZS6KE: "Paul ZS1V has an APRS igate out in Somerset West. I have a Midland where I programmed the EPROM but I’m not sure it’s on the right frequencies."

Please note: A 4 metre net is still running every Monday evening on 70,200 MHz from 19:00 CAT at Port Elizabeth and they would love to work Cape Town stations. 

BEACON REPORTS – Carl ZS6CBQ reported that according to Bernie ZS4TX the Bloemfontein beacon, ZS4AFV on 144,4145 MHz, is back on the air. Dick ZS6BUN heard it at KG43gm on Tuesday afternoon at 5/3 around 14:00 CAT on his 2x12 element H-pol Yagi array into a TS2000 with no LNA.  At the time Willem’s ZS6WAB/b on 144,410 MHz was coming in at 5/5 with the same set-up.  Ken ZS6KN heard ZS6WAB at 1/5 at KG44bj 

LATE VHF NEWS FROM CAPE TOWN – “Thursday evening we had a great turn out for our 2m SSB net :ZS1K, ZS1AX, ZS1TK, ZS1CF, ZS1ROD, ZS1WWW, ZS1EZ, ZS1OPB, ZS1TAF & ZS1VDV. Last week we were not able to communicate with Charles ZS1CF in Langebaan, but this week there were 2-way reports between Charles and ZS1WWW, ZS1AX & ZS1K.

“Most stations for the sake of the Net are vertically polarized, but there are a few of us that are horizontal: ZS1TK, ZS1ROD, ZS1PDY, ZS1LS & ZS1TAF. So any stations further afield that want to try work CPT you can contact me via this forum, or The Radio Shack forum, email or our VHF WhatsApp group - 73 de Mike ZS1TAF. Cell No.076 278 5622.”

THE RISE OF MACHINES CREATED BY ARTIFICIAL INTELLIGENCE – Dr. Hugo de Garis, an Artificial Intelligence researcher, claims that Artificial Intelligence (AI) will equal the human being around 2020, and thereafter will supersede it. What once appeared only as science fiction is now beginning to manifest in intelligent robots and it is not going to end there. AI chips in the future could be a trillion times more effective than the human brain. Future robots could solve current scientific problems and make discoveries that we have not even dreamed of. Conscience and emotions could be programmed into robots, and they could reach a stage where they could replicate themselves too. The danger is that sophisticated robots of the future might regard the human race as inferior and erase them!

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.
