SARL Fund for Disaster Victims

I am pleased to announce that Council have decided, on short notice, to establish an independent General Disaster Trust Fund to assist fellow radio amateurs who have suffered because of natural disasters. In a nutshell, this general disaster fund will be administered by independent trustees and not by Council.

The trustees in no specific order are Gary Immelman, ZS6YI, Louw Erasmus, ZS6LME, Cliff Smyth, ZS6BOX, and Rassie Erasmus, ZS1YT.

Trustees will have absolute discretion how funds for the current and for future major relief situations are to be utilised.

This is an open and honest initiative from Council to establish a fund for the current and for future major relief situations to assist in extra ordinary circumstances and not ordinary charity circumstances.

Contribution can be paid into: Erasmus Incorporated Trust Account ABSA Bank, Account no 4049478830

Please use your callsign as reference or should you prefer to contribute anonymously use the word “Disaster Fund” as reference”

The thread “SARL Fund for Disaster Victims” on the Forum will be used for reporting progress, acknowledge payments and for announcements. Please note that no general chatter will be allowed, especially negative remarks or criticism of any kind.

Many thanks for your generous support and understanding with this initiative.

73, Nico, ZS6QL, SARL President

NVIS PROPAGATION  - UNDERSTAND THE  BASICS - Radio Communication via Near Vertical Incidence Skywave propagation  can be used for communication over a wide area. It is very well suited for emergency communication. It uses frequencies between 3 and 10 MHz with amateur allocation in the 5 MHz particularly attractive.  Two propagation researchers, Ben Witvliet  and Rosa Ma Alsina-Pages wrote an interesting paper with lots of reference to  other papers for additional reading.

International Lighthouse Weekend. I had a quick look at the ILLW website and note that ZS1CT will be active from Green Point lighthouse in Cape Town, with ZS1OAR active from the Danger point lighthouse. Dennis, ZS4BS is applying for a call sign to activate the Great Fish lighthouse near Port Alfred, while ZS5HAM will activate Green point lighthouse in KZN (yes, there are two Green point lighthouses.) ZS5D will activate the Cooper Lightouse. I know that the Boland ARC are planning to activate the lighthouse at Agulhas. I am sure the list will lengthen as we get closer to August.

Check and Change Batteries BEFORE the Contest. This tip comes courtesy of Doug, W7ZZ: 'In the middle of the 7th Area QSO Party, while my computer was activating the transmitter and repeatedly calling CQ via the .WAV file, the wireless keyboard's batteries died. I realized this as I tried to stop the transmitter from being repeatedly keyed, calling endless CQs. Typing didn't stop the CQ, as it should have. The ESCAPE key didn't stop it either. After initial panic, I realized the batteries must have died and that I had no way to communicate with computer other than to power it down. I ran around the house and, fortunately, found a couple of AAA batteries, all while I'm calling CQ. I inserted the batteries, hit the "connect" button on the bottom of the keyboard and breathed a sigh of relief as the CQs stopped. Never will I start a contest again without fresh batteries in the keyboard and mouse!'

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 25 June 2017 


RSGB COMPLAINS ABOUT 50 MHz DIGITAL FREQUENCIES – The secretary of the SARL reeived the following emails from the RSGB that reads: 

"In the UK we have had a number of 'issues' with people who are operating JT65 on 50,276 MHz which is outside the RSGB and IARU Region 1 band plan. The 'working frequencies' included in WSJT software seem to have been chosen by some 'ad-hoc' user group and do not even comply with the ARRL band plan which states: '50.3-50.6 All modes. 

"By including 50,276 MHz and other frequencies in the latest releases of WSJT software it seems that there are some who wish to impose a de-factor in the 50 MHz band plan. The issue of 50 MHz and adherence to the band plan is of particular significance and has the potential to jeopardise our CEPT/ITU aims to gain 52-54 MHz at the next WARC. 

"If you agree with my complaint perhaps you might be inclined to also similarly complain to Joe Taylor K1JT. 

73 John G4SWX." 


"Dear IARU Region 1 Colleagues,

I call to your attention that a recent message from G4SWX makes incorrect assertions about "latest releases of WSJT software". 

"The authors of WSJT, MAP65, WSPR, and WSJT-X have never attempted to impose standards for operating frequencies of our various modes. Sometimes we have made initial suggestions, usually with IARU Region 2 in mind.  But the frequencies in use today are effectively established by users, not by us.  When conventional usage seems well enough established by the community, we have added mode-specific default frequencies to a list in WSJT-X -- often replacing our original suggestions. 

"The frequency list in WSJT-X is nothing more than a list of suggestions.  Its entries are easy for users to add, delete, or change.  If the community decides to move 6m JT65 activity from 50.276 to (say) 50.376, we'll be happy to change the suggested entry in the table.  Similarly for MSK144, and other modes. "With best wishes, -- Joe Taylor, K1JT." 

Please note: South Africa has been allocated 50 – 54 MHz in Region 1, unlike Europe who are still limited to 50 – 52 MHz in the same region. 

SINGLE HOP SPORADIC-E BETWEEN UK AND JAPAN OR IS IT SSSP? – Ian Roberts, ZS6BTE, received an email from a listener in Northern Germany who copied Japanese stations on JT65. It is claimed to be one hop Sporadic-E all the way from the UK to Japan – no intermediate distance VHF noted. A second email arrived that reads: “Hi Ian, This morning again (6th June): R1 is empty besides some weak peaks while 6m EU-Japan skips (attached). Still wondering: When entire Japan is involved, why not the Wladivostok region also? Ahh, now I see: There are no Bd1 tx. Mit freundlichem Gruß - Jürgen Bar.” 

POOR VHF PROPAGATION ALONG EAST COAST THIS WEEK – Peter Tottle, ZS2ABF, informs us from East London that VHF propagation does not seem to be very good along the East Coast of SA at the moment. He called Dave ZS5DJ, but nothing heard on 144,300 MHz USB horizontal.       

DIVISION 4 & 6 QSO’s ON 432 MHz AT S9 – Carl Minne, ZS6CBQ, reports from Krugersdorp: “Conditions inland is very good most mornings from about 06:00 CAT. I have regular contacts with Johannes Louw, ZS4WW, and Petrus Lindeque, ZS4PF, in Welkom during the week, and this morning (Tuesday 20th June) signals were S9 +20 dB. We moved to 432,200 MHz SSB on the 70 cm band and reports were also 5/9. At the moment my 70 cm Yagi is only roof high at about 7 metres. 73 Carl.”

Etienne Swart, ZS6Y, at Strubenville says now that the cold front is moving in 1296 MHz should also work well.  

NASA’s KEPLER SPACE TELESCOPE DISCOVERED 219 MORE EXOPLANETS – The NASA Kepler mission has discovered 219 more exoplanets, including 10 Earth-size planets, AS announced at NASA's Ames Research Center in California. Ten of the planets are potentially rocky, close to the size of Earth and within the habitable zone of the stars they orbit, meaning they could support liquid water on their surface, With the addition of this latest release, Kepler has now identified 4034 planet candidates, and 2335 of them have been confirmed as exoplanets. The mission has also found 50 candidates similar in size to Earth, with more than 30 of them confirmed.

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.
