BLOEMFONTEIN 5 MHZ BEACON ENHANCES THE SARL PROPAGATION RESEARCH PROJECT - The South African Radio League SARL propagation research project is based on a number of automated beacons using a program called “Weak Signal Propagation Reporter” (WSPR). During the July the scope of the project was greatly enhanced when a beacon was installed in Bloemfontein.  The Bloemfontein beacon is a complete system that was developed by Paul de Kock ZS6EHG of the Kempton Park Amateur Radio Technical Society. Paul developed a standalone system based on the Arduino hardware and software.

Paul experimented with the code and besides generating WSPR signals it also includes a brief transmission in Morse code which enables persons who do not have the WSPR software to identify the beacon. The beacon network transmits on 5 290 kHz Click here to read full article (PDF)

NEW SARL SECRETARY EMAIL ADDRESS - the scretary's email address has been changed to 


Youngsters On The Air 2015 off to a great start - 5th Edition of Youngsters On The Air started last Saturday in Marina di Massa, Italy.

 #RENEWAL OF AMATEUR RADIO LICENCES AND FORM B - Form B is no longer required. Amateur radio licenses are due on 31 March 2015 ICASAhas sent out reminders in January but the responsibility remains with the licensee to ensure that the license is paid. Unpaid licences will expire at the end of April.Radio amateurs also have the option to pay for 5 years. Simply send an email to  and advise him that you are converting to a 5 year license then when making payment, pay R500. This is a saving of R100 and protects the licensee against inflation increases which will be introduced from the 2016 license year. When paying ICASA please ensure that you quote your licence number and callsign..

HF UPDATE WITH ZS4BS (updated 27 July 2015) 

Club Log's Most Wanted List. The latest Most Wanted List, generated on 20 July, is available at The "Filter by continent" has been fine-tuned with the addition of AS Far East, AS Middle East, EU East, EU West, NA East Coast, NA West Coast and OC, VK and ZL. The information is derived from QSOs uploaded to Club Log (as of 15 July there were 301.3 million log entries available for analysis) and, to improve quality, only QSOs that have QSLs confirmed are considered to be worked. 

VOACAP News. VOACAP Propagation Planner v2.0b is a comprehensive and free-of-charge planning tool for HF contesters and DXers. The new online version  does all  heavy-lifting and  number-crunching on the  VOACAP server, and  visualizes  the results  graphically  in two ways - by CQ or  ITU Zones (short-path or long-path) and by band-specific zone charts (SP and LP), see 

VOACAP DX Charts is a "spin-off service” that calculates short-path and long-path HF propagation predictions from the user’s QTH to some of the upcoming DXpeditions, see 

Ethiopia, ET. There is a group of amateurs active from ET3AA, the Ethiopian Amateur Radio Society club station on the HF bands until 21 August. QSLs only via US0LW.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM (20 July 2015)

ELECTRONICS? – In 1929 Herman Weyl, a German mathematician and theoretical physicist, proposed the existence of a massless particle with an electric charge. The electron would be split into two Weyl fermions, but it was never discovered until now. A team of scientists at Princeton University made the discovery inside a synthetic metal crystal of tantalum arsenide when it was bombarded with a beam of high energy photons. The fermions behave like both matter and antimatter with opposite charges, and can move independently without any resistance just like in a super cooled circuit. This would be a boon for faster electronics in the future including quantum computers.

ZS5DCF CW SIGNALS COPIED BY ZS6BUN – “Deon ZS5DCFand I heard each other on CW 144,320 MHz this morning. The duct opened at about 06:40 local and lasted to about 07:15. Signals were weak, very, very weak but I was able to make out call signs and send a report. Regretfully I didn't get a report back so it doesn't count as a QSO but it was a good beginning. FYI, the IARU Region 1 definition of a minimal QSO is: A valid contact is one where both operators during the contact have (1) mutually identified each other, (2) received a report, (3) received a confirmation of the successful identification and the reception of the report - hence the R (signal report) and RRR messages.   “Path length about 600 km. My setup: 500 Watts and 2 x12 H-polarized Yagis. Deon is the first station I have heard from Durban proper. Now we just need to have a formal QSO. Anyone else for tennis? 73 Dick ZS6BUN.”

 “Yes, I spoke to Deon this morning (about 80 km) on 2 and 6 metres as we did some tests and he told me all about his QSO with you. Are you now permanently in Nigel Dick or was this QSO from elsewhere? Ben ZS5QM.”

PINE ZS6OB’s 144 MHz EME ACHIEVEMENTS – Jan “Pine” Pienaar, ZS6OB, of Wingate, Pretoria, is only the second radio amateur in the Southern Hemisphere who was awarded with a DXCC for 144 MHz EME. Here is a summary of his EME achievements.

EME on 144 MHz

1. DXCC  Worked   124           Confirmed    109

2. GRIDS Worked   543           Confirmed    382

3. Initial QSO's                        Worked         914

4. VUCC Worked    361           Confirmed    154 

5. WAC on 144 MHz and 432 MHz

He only needs ZS3 to have completed EME QSO's with all ZS divisions. 

VHF CONTACTS ARE POSSIBLE COUNTRYWIDE – Dick Coates reports: “I will be spending more and more time at the Nigel QTH from August onwards. This means I will have more time, particularly in the early mornings, to run skeds and tests with the ultimate objective of getting more stations round the country into long distance weak signal contacts on VHF.

“There is a substantial Cape Town Group, the coastal ZS2 to ZS5 group and the ZS4 group and the immediate objective is to get these groups making contacts with each other on initially, 2 metres. ZS4 to ZS6 QSO's are now a relatively regular feature of weekend mornings and with Deon's enthusiasm, we should be able to demonstrate ZS6 to ZS5 QSO are not as difficult as many imagine.

“Even ZS6 to ZS1 and ZS2 distances are not insurmountable. These distances are regularly achieved in Europe where the level of activity is sufficiently high that "openings" or "lifts" are recognized and exploited. We cannot blithely assume that Es never happens here, there's just not enough activity to recognize it when it happens!” Dick’s Cell number is: 082 600 7398.

THE AMATEUR RADIO PARITY ACT IN US SENATE – US Senator Roger Wicker (R-MS), who sponsored “The Amateur Radio Parity Act of 2015” in the Senate, said that the legislation would ensure that Amateur Radio operators are able to continue to provide “critical communications support at no cost to taxpayers.” Wicker also pointed out that private land-use restrictions prevent many hams from installing functional outdoor antennas. “This bill would call on FCC to apply the reasonable accommodation policy evenly to all types of residential land use regulations and offer Amateur Radio operators the ability to negotiate with subdivisions that now have restrictions that preclude Amateur Radio antennas completely,” he said. “This could be accomplished without taking any jurisdiction away from homeowners associations and would protect neighbourhood aesthetics.” Maybe ICASA could also look into South African amateur antenna restrictions. 


NEWS FLASH! PY1MHZ QRV ON 144,300 MHz DURING 15 DAYS VACATION – Marcos PY1MHZ in Rio de Janeiro, Brazil, locator GG98lc, is using a FT-847d with 300 Watts linear into 2x12 element LFA array and beaming to Namibia and Cape Town. His receiver will be running day and night during this period.

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.
