**** Project Lexicon achieves yet another milestone. The website which is used for the translation of the English words and phrases into Afrikaans is now officially open for use. There are currently 500 words on the website. The purpose of the web site is one to facilitate and to manage the translation of the English words into Afrikaans and secondly to integrate the translation process with a workflow at the backend which will assist the translation team in finalizing the translated words and to lock these the words already translated. This helps in that the wordlist will get shorter as words get translated and only remaining words will be available on the site for translation.
All radio amateurs and members of the public are invited to register as a user on the website and start translating. We have a milestone of end of September 2016 by which all words have to be translated. Persons who would like to participate is hereby requested to visit the website at , register as a user with a username and password and Bob's Your Uncle, you are ready to start translating.
Up till now we have 13 registered users on the site, 2 from division 1, 2 from division 4, 8 from division 6 and 1 from overseas. Clubs are invited to challenge each other to translate as many words as possible. Your participation will be highly appreciated. For more information please contact the project leader Etienne Naude at

**** The scattering of VHF radio waves as well as light waves are caused by dust particles and disturbances in the atmosphere, where VHF signals or higher could travel a long way. Tropo Scatter is present daily throughout the year, but produces very weak signals on 50 MHz to 10 GHz over distances up to 1000 km, which can be worked with high gain Yagi arrays, high power and sensitive receivers. The deep QSB cycles are caused by phase differences of signals travelling along different paths to the receiver, When you hear a Tropo Scatter signal fading out then stay tuned, it will return to its full strength within a minute or so. John ZS2AH at East London and the author at Port Elizabeth used to work each other nightly over this 250 km path on 144 MHz FM during very poor propagation conditions when there were no temperature inversions present, it was like surfing a wave at the peak of the QSB cycle.

Two-way contacts have been made between Divisions 1 and 5 during the early morning as well as at night via this mode, which was proven by Naz ZS1NAZ in Cape Town and Ben ZS5QM at Hilton across the Drakensberg while using 400 Watts. It is possible to work distances of several hundred kilometres almost daily via this scatter mode using a VHF transmitter with only 100 Watts output and a horizontal Yagi beam antenna, but signals are strongest during early morning and late evening. Tropo Scatter signals with its deep QSB are always very weak in comparison with Tropo Enhancement and Ducting, which are both weather related.

**** As you might have heard, the EAST RAND high site had been broken into over the last week end and damage to the amount of R30000-00 had been incurred. K A R S had undertaken to pledge R500-00 to assist our neighbors in repairing and rebuilding the high site. We would like to challenge all other clubs to equal or beat our pledge to assist ZS6ERB

**** The SARL Amateur Radio Hall of Fame honours individuals who have made significant contributions to amateur radio in South Africa. Their memory will be preserved on a page on the SARL Web site. The first group of members will be inducted into the Hall of Fame at the SARL AGM in May.

Essays outlining the contributions of the 18 nominees can be found on the Hall of Fame page, accessible through a link on the Web site front page.

Reading the nominations is well worth your while, as the nominees have shaped our hobby. They include historical stalwarts like John Streeter, Dixon Bennett and Dave Larsen, as well as modern-day contributors to our hobby.

Vote today! Over 300 votes have already been cast, and voting closes on Thursday.

SA AMSAT has changed the SA in its name around and will now be known as AMSAT SA. The amateur radio satellite group made the decision to line up its name with the organisation's web address. It was confusing having the name and web address different. It now also follows the international trend of other AMSAT organisations. AMSAT SA has also been registered as a non-profit company and is in the process of applying for tax exemption status with SARS.
Membership conditions of the organisation remain the same. To get more information visit the or down load a free copy of the March 2016 Ezine available from Monday 28 March 2016

40 STUDENTS LEARN ABOUT AMATEUR RADIO AND SATELLITES On Wednesday last week 40 leaners from schools around Pretoria attended a morning workshop about amateur radio and satellites. The workshop was part of the Innovation Hub holiday programme during which grade 10 and 11 leaners are exposed to various work and science situations. AMSAT SA was invited to talk about space related activities. The workshop was presented by Nico van Rensburg ZS6QL and Hans van de Groenendaal ZS6AKV. The workshop started with a talk about amateur radio illustrated by short video clips. During practical demonstrations the learners were shown how a transponder works, how satellites orbit around the world and how antennas are used to track satellites including using smartphone applications.
