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 


FM BROADCASTING STATIONS AS VHF BEACONS

In the USA they have often observed strong signals from distant FM broadcasting stations during Sporadic-E openings beyond the skip distance. This is also possible in South Africa during December and January months, which is our Sporadic-E season. Just keep an eye on those clear spaces on the FM band where distant FM stations are hiding in the noise. FM stations could also act as VHF beacons on Tropospheric modes, as well as indicators of meteor scatter and lightning scatter. ZS2FM at Port Elizabeth studied the propagation from an East London FM station for about a year over a distance of 250 km, while using a four element vertically polarized Yagi in the attic connected to a domestic FM receiver. The FM station was audible daily via Tropo Scatter, but with very deep QSB cycles, and yielded a peak signal of about 2 microvolts as measured at the antenna terminals of the receiver. During Tropo Enhancement, where a temperature inversion was present below 450 metres, the signal increased to around 20 microvolts with full quieting and no QSB. When a cold front approached from the west it created a Tropo Duct ahead of it, which is a temperature inversion at an altitude of 500 metres or higher. This produced a super FM signal that peaked above 50 microvolts, and the maximum that could be measured at the receiver. So give it a try

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!'

MORE VHF NETS ON 144,300 MHz PLANNED FOR THE WARMER MONTHS – A long distance VHF net is being planned from Port Elizabeth on Thursday evenings starting in the warmer months in August or early September on 144,300 MHz SSB. There will be two sessions at night, one beaming north to Bethulie, Welkom, Bloemfontein and Bethlehem. The second session will point west to cover Knysna, George, Mossel Bay and Cape Town. There is also the possibility of joining an existing net between East London and Durban on Monday evenings. We will alert you when it starts, and hopefully when propagation exists then a VHF link could be established with five different cities. In the meantime get your beam antennas sorted out. 

EHF & SHF NEWS FROM OVERSEAS – New UK Records on 122 & 241 GHz. The RSGB confirmed that the existing 122 GHz and 241 GHz UK distance records were both extended to new distance of 6,8 km with two-way contacts in CW between John Hazell, G8ACE, operating from his home, to Ian Lamb, G8KQW/p located at Shroner Wood, Winchester. The contact took place on Sunday, 21 May. Transmit power levels were around 200 microwatts at both ends on both bands, and the antennas were 30cm dishes with separate 122GHz and 241GHz feed horns. RST was 539 each way on both bands.
 

A radio amateur received the Cassini spacecraft on 8,429 GHz. The ARRL reported that Paul Marsh, M0EYT, has confirmed reception of the Cassini spacecraft, now in orbit around Saturn.  He copied Cassini on 8.429.247035 MHz during its last radio occultation experiment, where the TX is carrier-only mode on S, X, and Ka bands. Marsh was using his 2,4 metre antenna at the time, while his homebrew downconverter was locked to a 10 MHz station reference, and SDR processing was done with the RF Space kit. 

Launched in 1997, Cassini will crash into Saturn in early September. The research spacecraft, which carried the European Space Agency’s Huygens probe now on the surface of Saturn’s moon Titan, currently is executing about 2 dozen dives through Saturn’s rings. The Huygens probe separated from the orbiter in 2004 and transmitted data to Earth using the orbiter as a relay. This was the first successful landing in the outer solar system. Marsh is heavily involved with satellite tracking and monitoring activities and is a contributor to the Amateur Deep Space Network (Amateur-DSN).

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.

A
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.
