2018 ARRL HANDBOOK The Handbook has been extensively updated, and includes significant new content. Each chapter has been authored and edited by experts in the subject.

For the new ham…you will be amazed at how quickly you become familiar, not only with the theory, but also with the practical aspects of radio – from long waves to microwaves.

For the experienced ham…you’re in for a surprise and delight when you see the extent of the latest revisions. This edition is the most comprehensive revision since the 2014 edition.“ For more  details click here

EXCITING CHANGE FOR AMATEUR RADIO TODAYIn December the SARL announced exciting changes for the SARL Magazine programme, Amateur Radio Today. From 21 January, the programme will be in English only and will have an expanded subject content with the main focus on technology and activities that drive the growth of Amateur Radio, not just in South Africa but also on the African Continent and surrounding islands. The new format will also meet the IARU’s call to focus on the development and expansion of Amateur Radio in Africa and will become more in line with Sentech expectation that the programme must focus on technical development and encourage experimentation. Old favourites such as the Hamnet, satellite and HF reports will remain a main feature. There will be a new feature weekly featuring VHF activities edited by Mike Bosch ZS2FM as well as amateur radio news from around the world in “Focus on the world”. 

Amateur Radio Today is inviting persons with an interest in editing and presenting inserts or become an anchor presenter to send a mail to with their contact details. 

Dawie Conradie, ZR6DHC, who co-produced the programme with Hans van de Groenendaal will be taking a break to spend more time on family and work matters. He told SARL President, Nico van Rensburg that once things have settled down he will return to the fold. “I would like to thank Dawie for his many years of dedication to the programme and look forward to working with Dawie in future on Amateur Radio Today and Amateur Radio in Aksie,” Nico said. 

It was envisaged that Amateur Radio in Aksie would shift to an earlier slot between 9.30 – 10 am local time and still be available for download on the SARL Web. However, Dawie and his colleagues have decided to take a short break to refocus on the programme. Dawie told SARL news that they will be back with Amateur Radio in Aksie soon. Details will be announced in SARL News. 

The IARU Region 1 VHF/UHF Newsletter - No 76 is available for download. It contains a report of the work done by the Region 1 VHF/UHF Committee since the 2017 Region 1 General Conference.

The DUBUS Magazine - The magazine for the serious VHFer and up. The subscription for DUBUS is due again. The cost for 4 copies will be R 365.00 - The distributors have decided to give DUBUS to us at a very low price.

If you are interested in receiving the magazine, contact Pine, ZS6OB, at as soon as possible, he needs to notify the distributors of expected numbers from ZS by the end of January 2018.

DPØGVN WSPR Beacon in Antarctica is operational. On 15 January in the afternoon hours, the multiband receiver of the new permanent WSPR beacon DPØGVN in Antarctica was put into operation. It is active from the German research station "Neumayer III" of the Alfred Wegener Institute for Polar and Marine Research. The installation is part of a scientific project of the Technical University of Munich in cooperation with the University of Bremen and the German Amateur Radio Club (DARC). The beacon is still under test and will be shut down occasionally for more configuration and optimization of antennae and software before it can be mounted to the final installation site in a few weeks. Currently, there are three radio specialists (Felix DL5XL, Matthias DH5CW, and Daniel, DL1SU) at the research station, all being amateur operators and DARC members.

AX prefix on Australia's national day. The Australian Communications and Media Authority (ACMA) automatically allows all radio amateurs to substitute their normal VK callsign prefix with the letters AX, every Australia Day. Australia Day in 2018 falls on Friday 26 January and gives radio amateurs the chance to be part of the commemoration the First Fleet's arrival in 1788 at Sydney Gove and the establishment of a European settlement at Port Jackson, with the raising of the British flag by Governor Arthur Phillip.

On Australia Day many celebrate Australia’s country and culture. This includes the granting of awards, honours and the welcoming to citizenship of many immigrants. National flags will be flown and the celebrations include fireworks displays. The AX prefix is popular among prefix hunters and others. The use of a special QSL card is encouraged by the Wireless Institute of Australia.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 14 January 2018 


CALLING ALL VHF AMATEURS IN SUB-SAHARAN AFRICA – There must be at least a few HF amateurs in the following African countries, who might become interested in VHF too. These countries are all within single-hop Sporadic-E range from South Africa. They are: Angola (D2), Zambia (9J), Mozambique (C9), Namibia (V5), Botswana (A2), Zimbabwe (Z2), Swaziland (3DA) and Lesotho (7P). FM sound channels of Band III television stations, grouped around 53,750 MHz, have been heard almost daily at Port Elizabeth in earlier years, from around 12:00 CAT for an hour or two during the Sporadic-E season. On rare occasions a French speaking station, possibly from the Congo, has also been copied at signal strength of S9 on FM. Since both the Congo and Kenya are on the Equator double-hop Sporadic-E communications should also be possible at times on VHF with them. Many African TV stations have gone satellite, but there are still a few left that could act as beacons, so watch the frequencies around 53,750 MHz on FM. 

So the question is how many radio amateurs from the African states would become interested in VHF communications? Even if only one amateur in each country would take up the challenge and run some skeds or maybe erect a VHF beacon, then we could learn a lot about the strong Sporadic-E propagation conditions that prevail in mid-Africa. Likewise we could for the first time get to know something about Tropical Tropo propagation, which is affected by wind shear etc. If you are listening to this programme from somewhere in Africa, then please try and send a list of amateurs in your area with their email addresses to RT TODAY. We would like to encourage some of them to develop an interest in the exciting world of VHF and above. 

FINDING A VHF PATH TO VK – Andy Hemus, VK6OX, at Carine, Western Australia sends his Happy New Year wishes to everyone, and says: “I haven't been on the forum for quite a few years! As you may be aware the Es season in VK/ZL has been outstanding, partly due to the activity generated by the recent introduction of FT8, but also because a path has been found and worked between eastern VK and LU,VP8, CE etc. over the past 5 weeks. The main mode for QSOs has been JT65 but a couple of completions have occurred on CW. The inevitable question arises …. if a path can be found between VK and South America, then why can't a path be found between VK and South Africa? We tried with a few of your guys a few years back without success, but I think we should try again. Would love to hear your "positive" thoughts HI!  73 Andy VK6OX. PS: emails are welcome!” 

ABERDEEN, EASTERN CAPE, WILL BE ON VHF SOON – Jerry van Zijl, ZS6BTL, has informed us that he has moved from his farm in Gerdau to Aberdeen. Jerry was a very keen VHF-er in his early days and worked ZS2FM in Port Elizabeth on 50 MHz. Jerry said that he would erect his 50 MHz and 144 MHz beam antennas at his new QTH, which is just over 200 km from PE, and well within Tropo Enhancement propagation. His new call sign will be ZS2TL.


HI FROM THE GUYS ON THE SOUTH EAST COAST – “Dave ZS5DJ and I have been coming on 144.300 MHz from time to time during the Festive season, but we have only heard the two of us. Last night Thursday 11 January 2018 was very good, and we Rag Chewed over the 325 km for about 3/4 of an hour. There was some deep strong QSB at times. Conditions were so good, and the signal was so strong, we changed to FM mode and it was studio quality, better than a telephone. The Hepburn charts predicted more or less the same for tonight (Friday). Please join us if you can spare the time. We will give breaks to let you in on the QSO. Peter Tottle, ZS2ABF.”

W1AW BEGINS SCHEDULED TRANSMISSIONS ON 50 MHz IN JANUARY – Beginning with the 14:00 UTC fast code practice transmission on Tuesday, 2 January 2018, W1AW will add 6 metres — specifically 50,350 MHz — to its regular CW code practice, and CW, digital and phone bulletin transmission schedule. In addition to providing regularly scheduled transmissions on 6 metres, another goal is to act as a beacon on 6 metres, especially from the Northeast US.

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.
