CME STRIKE SPARKS GEOMAGNETIC STORMS: Geomagnetic storms are underway on July 16th following a CME strike at 0545 UT. Auroras have been sighted in New Zealand as well as US states such as Washington and Wyoming. G1-class storms happening now could intensity to G2-class in the hours ahead as Earth moves into the CME's magnetized wake..

Ian Griffin sends this picture from New Zealand. "I was observing at Hoopers Inlet on the Otago Peninsula when a fabulous outburst of aurora occurred just after the CME from sunspot AR2665 hit," he says. "The colours and reflections on the inlet were truly beautiful. I was so excited I took this aurora selfie!"

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.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 16 July 2017 


THE GREAT ACHIEVEMENTS OF OUR EARLY RADIO AMATEURS – Our early radio amateurs were great experimenters and pioneers, they were responsible for the ITU to recognize amateur radio as an official radio service, and therefore entitled to dedicated amateur bands in the radio spectrum. 

1921 – Paul F. Godley set up a temporary radio listening post in Scotland and picked up for the first time amateur radio signals from the USA on the shorter wavelengths. 

1923 – Leon Deloy 8AB in France and Fred Schnell 1MO in the USA, made the first intercontinental DX QSO on shortwaves. In the same year KDKA in Pittsburgh, Pennsylvania, USA, started operation on 100 metres (3 MHz) to become the first shortwave broadcasting station in the world. 

1924 – Radio amateurs were now making worldwide contacts on shortwaves, and John Streeter FO-A4Z made the first contact between the Union of South Africa and the USA on 36 metres. 

1931 – Amateurs in the USA started to experiment with phone on 5 metres (56 MHz) using super regenerative transceivers, and achieved distances beyond the line-of-sight limit on these Ultra High Frequencies. 

1934 – Ross A. Hull (ex VK3JU) discovered Tropo propagation in the USA over a distance of 160 km on 56 MHz, 112 MHz and 224 MHz (5, 212 & 114 metres respectively), which peaked up to S9 during temperature inversions.  

1937 – Bert Howes ZS1AL (later ZS6HS) in Cape Town received the AM TV sound from Alexandra Palace, London, England on 41,5 MHz, which was confirmed by the BBC as the longest distance in the world that TV sound has ever been heard at the time. 

ICY COLD CONDITIONS AFFECTED TROPO ON VHF IN RSA – Icy cold weather has spread across the country with snow on the mountains, even the southern coast is now freezing too after all the wild fires. Under these conditions Tropo openings can only briefly appear during approaching cold fronts, and there should be quite a few during this month. Anyway the warner months are coming. 

SOUTH EAST COAST – “Hi from the South East coast. Dave ZS5DJ and I were again on the 144,300 MHz on Monday evening sked. Conditions were not very good, but we managed to have a short QSO. No other stations were heard. 73 Peter ZS2ABF.”

FREQUENCY ALLOCATIONS TO BE EXTENDED FROM 275 GHz – 450 GHz INTO THE TERAHERTZ SPECTRUM – The World Radiocommunication Conference 2019 (WRC-19) will be held from 28 October to 22 October 2019. Agenda Item 1.15 to consider identification of frequency bands for use by administrations for the land-mobile and fixed services applications operating in the frequency range 275 - 450 GHz, in accordance with Resolution 767 [COM6/14] (WRC-15) 6.1 IARU position on Agenda Item 1.15 Resolution 767 (WRC-15) recognizes that the amateur service is developing and demonstrating applications above 275 GHz. As studies proceed to identify candidate frequency bands for the land-mobile and fixed services in the frequency range 275 - 450 GHz, the IARU supports maintaining access for non-commercial experimentation by stations in the amateur service to as much of the frequency range as possible, consistent with the protection of the passive and other active services.

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.
