ICASA informed the SARL that they have analysed all payments for licenses. Two hundred and nine Radio Amateurs paid R501 in 2012 but did not notify ICASA that they were applying for a 5 years license. This year, 2013, there were 34. ICASA will next week mail five year licenses which will be valid until 2017 and 2018 respectively. Please allow time for the mail system.

The investigation also showed that this year 823 radio amateurs did not renew their licences. These licences will be cancelled and ICASA will make arrangements for the urgent sealing or confiscation of the equipment if payment is not made immediately.

Radio Amateurs are urged to check their own payment records. It is the licence holder's responsibility to pay the annual license fee whether an invoice is received or not. If you have not paid your 2013/2014 license fee, do so without delay. A one year license costs R120. A five year license costs R501. Please indicate if you are paying for a one year or 5 year license. Also include your licence number and your call sign with your payment.


The exploits of Craig Hayhow, VK0JJJ, in bouncing radio signals off the moon from Antarctica has been written about in the Australian Antarctic Division science newsletter.

VK0JJJ achieved a 742,000 kilometer hop when he made an EME contact with Peter Taylor G8BCG at Cornwall in England, on May 4th. Two nights later he contacted Bo Nilsson, SM7FJE, in Sweden through another EME contact.

The newsletter hailed these as a first from an Australian Antarctic station. It also notes that the equipment and software has now been proven and that more EME contacts will be made.


News line reports that it is the end of an era for an old but reliable form of communications in India. The newspaper the Hindu reports that on July 15th the telegraph service will come to an end.

India's first telegraph message was transmitted live between Calcutta and Diamond Harbour on 5 November 1850. That was a distance of about 50 kilometres. The service was opened for use by the general public in February 1855 with a Radio-telegram system between the UK and India established in 1927. It appears as if more modern technology such as Instant Messaging and social media sites have taken their toll on another communications technology of times gone by.


The FCC, the agency that regulates the radio frequency spectrum in the USA, issues amateur radio licences to residents and non-residents alike. An American licence is useful for reciprocal licences in many countries that do not have an agreement with South Africa.

The C82DX operation in October provides an opportunity to hold a licence exam, as the crew includes enough Volunteer Examiners to conduct a licence session. If there is enough interest, the session will take place in the Pretoria area in mid-October.

There are three licence classes: Technician, General and Extra. A candidate can sit all three exams in one session. Each examination consists of technical and regulation questions applicable to the respective licence class. A candidate can take one, two or three exams depending on the licence class required. Several vendors, including the ARRL, provide suitable study material. An existing South African licence holder should have no difficulty mastering material.

If you are interested, please contact Tjerk Lammers ZS6P or Chris Burger ZS6EZ. Candidates will be advised timeously of schedule and venue information.


Our Sun is a yellow star that consists of a giant ball of superheated plasma, its magnetic field oscillates and acts as a dynamo that creates the sunspots, solar flares and strong magnetic storms in the solar system. When a Coronal Mass Ejection (CME) appears from the corona of the Sun and travels to the Earth then the magnetic field of the Earth would deflect it, and create auroras in the form of ovals around the magnetic poles of the Earth.

Scientists claim that if a super CME should hit us then this magnetic storm will penetrate the Earth's magnetic field and cause devastation. First of all the satellites would be destroyed and all satellite telecommunications and DSTV would go off the air. Then it would generate extremely high voltages in the power lines and blow up all the transformers in the substations causing complete blackouts in cities and towns. Since water pumps won't function cities would dry up over night.

A solar storm hit the Earth on 13 March 1989 and caused blackouts in the entire province of Quebec, Canada. Scientists are currently keeping a very close eye on the Sun with a dedicated satellite, while trying to develop shielding that could protect transformers during such an event.


The Hamnet winter Challenge is this year a national event. It will be held from 12:00 on Saturday 3 August till 12:00 on Sunday 4 August. One of the frequencies to be used is 5260 kHz. It should be noted that only Hamnet teams may participate. Others who are monitoring the frequency are encouraged to log all the activity and send the log to as input to the propagation research project.

Hamnet groups who would like to participate should send the following information to the exercise co-ordinator, Pierre Tromp, ZS1HF, not later than close of business Friday 19 July 2013:

. Intended location (name and co-ordinates or 6-letter grid square)
. Name of team
. Full names and call signs of participants (preliminary list for entry, changes to be sent through to the exercise co-ordinator before the exercise)
. Indication of which team members are NOT Hamnet members, if any
. Which of the exercise channels you intend operating on

The exercise co-ordinator may veto your entry if your chosen location is too close to another team or one of the recognised Emcomm centres. Those who enter earlier have a better chance to be granted their choice of location. Since there is significant preparation required once the list of teams is known, no late entries can be accepted. Final instructions, including the messages required to be transmitted, the locations of the other teams and the channels they intend using, will be sent to all teams during the week before the exercise.


The SARL has produced a generic QSL card which you can personalise by writing in your own call sign. The cards are available in batches of 100 at R50 per batch, including postage. To order pay in the amount for the required number of QSL cards into the SARL account. Full details and an illustration of the card can we found on the members' only section of the web.

The SARL will be participating in the HF championship on 16 and 17 July from the National Amateur Radio Centre. ICASA has approved the special call sign ZS9HQ for the two-day event. Operators are needed. Call Geoff on 082 546 5546 or send him an email to to offer your participation.


The Sandton Amateur Radio Club will be conducting its RAE course for the second semester of this year. The course will begin this Thursday 27th June at 19h00 at the National Amateur Radio Centre with an introduction to amateur radio presented by Colin ZS6COL. RAE classes will begin on the following Thursday - 4th July at 19h00 at the National Amateur Radio Centre.

The Westrand Amateur radio club is hosting its next flea market 12:00 on Saturday 29 June 2013 at their clubhouse in Kroton street, Weltevredenpark, Roodepoort. Everybody is welcome. For more information contact Phillip ZS6PVT, 083 267 3835 or Geoff ZS6GRL 082 546 5546.


The IARU HF Championships takes place on the second full weekend of July, beginning 12:00 UTC Saturday and ending 12:00 UTC Sunday (13 and 14 July 2013). Both Single and Multi operator stations may operate the entire 24-hour period. The object is to contact as many other amateurs, especially IARU member society HQ stations, around the world as possible using phone and CW on the 160, 80, 40, 20, 15 and 10 metre bands.

The exchange for IARU member society HQ stations is a RS or RST report and official IARU member society abbreviation. IARU International Secretariat club station, NU1AW, counts as a HQ station. Members of the IARU Administrative Council and the three IARU Regional Executive committees send a RS or RST report and "AC," "R1," "R2," and "R3" as appropriate. All others send signal report and ITU zone and a complete exchange must be logged for each valid QSO.

Seven logs including 1 check log were received for the SARL Digital contest held on the 26th May and the results are as follows:-

Hannes Coetzee, ZS6BZP, reports that the solar activity is expected to be at low levels. There is a chance of C-Class flares and a lower threat for an isolated M-Class event.

If you want to do your own frequency predictions, the expected effective sunspot number for the week will be around 72.

All the bands from 20 to 10 m will provide lots of DX fun with 20 m providing the best openings with 15 m not far behind. There can also be some 10 m openings on sunlit paths.
