AMATEUR RADIO TO THE RESCUE

SARL AND SANSA DISCUSS CUBESAT

SARL HF PHONE CONTEST THIS AFTERNOON

>> It has been said so many times "when all communication fails, you can depend on amateur radio. This was again proven on 9 August when an important message from Gough Island to the department of environmental affairs could not be sent as their links were down.

The story started when Pierre Tromp, ZS1HF, volunteered to go to Gough Island in February 2014, after a member of the 2013/2014 Gough Team sadly passed away on the island. Pierre passed the necessary tests and was shipped to Gough Island, where he was allocated the call sign ZD9M.

Pierre and Trevor, ZS1TR started the 7110 SARL Hamnet Emergency Net in January 2014, and established daily communication on 30 and 40m depending on propagation. "We tried to maintain daily calls, but obviously due to the distance to Gough, we had to adjust our frequencies." Trevor told SARL News. "In the summer months we could work all bands, but as the winter approached it was trickier, mainly favouring the lower frequencies."

Communication later developed into a regular call-in at 10 minutes after the hour. As the winter approached the satellite signal from Gough to RSA became intermittent due to the cloud cover and other climatic conditions. Pierre's more reliable communication with home became HF Radio with Trevor relaying messages to the DEA's technician to try and get the satellite system reset and working again.

During the weekend of 9 August, a serious incident occurred on Gough Island. As the Satellite connection to RSA had been bad since the first week of August Pierre decided to radiogram it to Trevor for relay via email to Cape Town. The message contained 836 words, excluding the many email recipients, and was sent a few words at a time and corrected and repeated back for confirmation. The entire process took about 1 hour 45 minutes to transfer via HF radio, which forced them to alternate between 20 and 30m as conditions were fading in and out on both frequencies. "Cramping hands and wrists with worsening handwriting was the result, as typing is much easier, believe it or not! Thereafter the message was retyped into email format for sending to the recipients."

It again showed that when all fails, use amateur radio. Congratulations to Pierre and Trevor.


>> The next SARL Radio Technology in Action symposium will be held at the National Amateur Radio Centre at Radiokop on 23 August. Booking closes on Thursday this week but please do it as soon as possible. to help the organisers with their planning and catering. Full details can be found on the home page on the SARL web.

Tony Voorveld ZS6CCD will be delivering the keynote address entitled "The Magic Lamps". Another interesting presentation will be will be by Stewart Moss ZS6SGM talking about the WSPR 5 MHZ propagation research project and how easy it is to join it. Other presentations include : Antenna Modelling with NEC2 presented by Vincent Harrison ZS6BTY, Digital modes as applied in amateur radio - how does it work? Presented by Riaan Greeff ZS4PR, and the SARL Isolated USB Transceiver Control Interface kit presented by Frik Wolff ZS6FZ . Get the full details on the web.

The Pretoria RTA will be held on 13 September at the Innovation Hub, booking is already open.

>> The recent Canadian Transatlantic VHF DX-pedition, V1CT, has once again focused the attention on the proposed VK6RIO chirp beacon project, currently being planned across the Indian Ocean between Perth and Port Elizabeth.
The purpose of this beacon in Perth is to detect possible openings on 144 MHz via Tropo Ducting across the Indian Ocean, which has never been accomplished before. It is currently the greatest terrestrial challenge for VHF radio amateurs, and is even more difficult than EME. The beacon will be chirp modulated, and its signal can be detected at - 50 dB below the noise floor with suitable chirp receiving equipment and a high gain Yagi array. The receiver will be linked to a computer network that can be accessed by subscribers in Australia and South Africa who would like to monitor results.
The receiving station will be located in Port Elizabeth and co-ordinated by Mike Bosch ZS2FM.
The cost of the chirp equipment entails AU$1000 (R10 000) plus shipment to South Africa. On our side we have to provide the antenna Yagi array and the PC with server connection. Fortunately the antenna mast, with stainless steel guy cables, is already available.
Several years ago a Port Elizabeth team, comprising Andre Botes ZS2ACP, Jim Francis ZS2JF and Mike Bosch ZS2FM ran a series of CW tests on 144 MHz with Bill Hosie VK6ACY, now ZS6CCY, at Perth but unfortunately not even a trace of a CW signal was received over this 8000 km sea path.
YOU ARE TUNED TO A NEWS BULLETIN OF THE SOUTH AFRICAN RADIO LEAUGE AND WE NOW CONTINUE WITH NEWS FROM THE LEAGUE
>> During the past week the SARL and SA AMSAT met with representatives of the South African National Space Agency to develop a memorandum of understanding covering the establishments of a cubesat ground station a SANSA Space Operations at Hartbeesthoek. The station will support South African amateur and international cubesat missions. The objective of the MOU is to create closer ties between SANSA and the radio amateur fraternity and to jointly work with the regulatory authority to develop a legal frame work under which the ground station can be established.

If you want to do your own frequency predictions, the expected effective sunspot number for the week will be around 50.
The three DX bands from 20 to 15 m will provide some DX fun with 20 m providing the best openings with 15 m not far behind.
