SARL Today HF Update with ZS4BS VHF/UHF News with Mike Bosch ZS2FM Contest News with Geoff ZS6C SARL Forum current topics Commercial Hamads


NEXT STEPS FOR SARL ICASA MOU  and 5MHzCurrent cooperation between the SARL and ICASA has far outstripped the original MOU between the two organisations and was last year brought up-to-date. However due to the restructuring of ICASA and various delays in amending the ICASA delegation of authority, the signing of the MOU was delayed.    While the new MOU was agreed between the SARL and the ICASA licensing structure it had to go through a new review process including various departments. This process is now at the point where the MOU is on the agenda of the next ICASA Operations Committee. After approval it will then be submitted to the ICASA Council for final approval and signature.


In a parallel process the SARL recommendations for 5 MHz allocation presented to ICASA earlier this year, has now received approval from the frequency spectrum department and a document is in preparation for submission to the Operating Committee. The SARL proposal seeks the continued use of 5290 kHz for the WSPR propagation experiment and a secondary allocation of 100 kHz range which includes the WRC agreed range of 5351.5 – 5366.5 kHz and that the power allowed be 26 dBW. The SARL proposed 5350 – 5450 kHz which was the IARU proposal to WRC15.

At WRC15 South Africa and members countries of the African Telecommunications Union supported the proposal.  The Russian block was opposed. A compromise was reached to allocate  5351.5 – 5366.5 kHz. However many countries, including the Netherlands went ahead and gave their radio amateurs access to the proposed 100 kHz.  The South African process is very involved and may well have to include a public consultation process.

SARL AND SENTECH MEETING REPORT BACK - During last week a delegation from Council of the SARL met with representatives of Sentech regarding the future hosting of amateur radio repeaters currently on their high sites. The SARL received a notice of cancellation of the current Memorandum of Understanding (MoU) and the opportunity to negotiate a new electronic Communications Facilities Master Agreement.

Sentech introduced a facilities leasing policy with a financial budget to meet, which makes it difficult to provide services free of charge. To date repeaters were hosted on Sentech sites free of charge since the original Memorandum of Understanding (MoU) was signed in 1996. The purpose of the meeting was to discuss mutual cooperation and in particular the way forward regarding the continued use of Sentech sites for amateur radio repeaters. Both the Sentech and SARL delegates were satisfied with the discussions and a follow up meeting will take place once the action items agreed upon have been addressed including the necessary feedback received.

The four young Radio Amateurs who represented South Africa at YOTA 2016 in Austria reported back  about their experiences. They said they could not believe the tremendous technological development in amateur radio and how their European counter parts had embraced it. They also were amazed at the expert level of using CW as a communications mode. They met on Saturday 13 August  at the NARC with the sponsors who assisted with making their visit possible ( with also a lot of financial support from their parents). With YOTA month coming up in December they encourage young Radio Amateurs in South Africa to brush up on their Morse code as with the declining sunspot cycle CW will again become a popular mode.  The four, Koos ZR6KF, Michelle ZS6MEM, Rourke ZS6RDH and Ruben ZR6RJV, have great ideas about taking amateur radio to the youth  at  an excitingly  higher level. They would not speak about it  but said watch this space. 


Left to right the SA YOTA 2016 team with their sponsors : Mario ZS6MAR, Noel ZR6DX (Hammies) SamZS6BRZ, Michelle ZS6MEM,Reuben ZR6RJV, Koos ZR6KF, Rourke ZS6RDH, Nico ZS6SRL, Renier ZS6HOT.  Listen to Amateur Radio Today on 21 August for an interview with the four.

ICASA RULES ABOUT ZU LICENSES FOR PEOPLE OVER 25 - From  2017 amateurs over 25 years old who hold a ZU license cannot renew their  licence. ICASA recommends that the affected persons enrol for a class A license course and write the next RAE in  October 2016. That will be the last opportunity.

The revised regulation stipulates that persons under 20 years old can write the class B examination and if successful can hold a ZU or class B license until 25 years old after which, if they would like to continue with Amateur Radio, have to sit the class A examination to qualify for a class A (ZS/ZR license).

During the discussion stage of this new regulation the SARL was requested to approach ICASA to review their decision, which the SARL did on two occasions when ICASA invited comments on their proposal.  ICASA strongly believes that the class B license prime purpose was to create opportunities for young people to enter Amateur Radio and based on that premises implemented the new regulation. 

The SARL requested ICASA to allow a reasonable period for ZU licences over 25 to upgrade. ICASA agreed to this and set the final date as 31 March 2017.. If you are over 25 and still hold a ZU do not loose out. Write the October examination. Tutorial materials is available free of charge. Download here

Amateur Radio - a 21st Century Hobby. In just 10 months the RSGB video Amateur Radio - a 21st Century Hobby has been viewed almost 58,000 times on YouTube. Produced by the TX Factor team and launched at the 2015 RSGB Convention it is by far the most popular video the Society has released. It covers the wide range of activities open to radio amateurs and features a very active club at a Yorkshire School and radio amateurs from Essex Ham and Camb-Hams. The video was narrated by Essex radio amateur Kelly M6KFA. 

ARRL Awards on Twitter. As part of its expanding social media presence, the ARRL is resurrecting the Awards Branch Twitter feed, which has been inactive since 2013. The old feed (@ARRL_DXCC) will be deactivated on 1 September. The new feed (@ARRL_Awards) will include news, information and photos pertaining to all ARRL Awards, not just DXCC. It will also be the primary news feed for ARRL announcements related to DXCC accreditation of operations. 

Bhutan, A5. A52AEF (JH3AEF), A52ARJ (JA3ARJ), A52EQW (JH7EQW) and A52LSS (JH3LSS) will be active from Bhutan between 22 and 27 August. They will operate mainly CW and SSB on 80 to 10 metres. QSL via home calls, direct or bureau. 

Aves Island, YV0. The YX0V team of 14 operators is expected to depart at 12 UTC on 27 August. Depending on which Navy ship gives them the ride, the voyage might take 48 to 72 hours. Plans are to be active on all bands and modes from Aves Island (NA-020) for "up to ten days.” The website for the DXpedition is on 

Australia, VK. Craig, VK5CE, will be active as VK5CE/p from Granite Island (OC-228) many times over the next 6 to 12 months, “until demand is satisfied". These operations will be from local dawn to dusk only, as visitors are not allowed to overnight on the island. Depending on weather, Craig's first day trip activation will be on 27 August. Look for him from 23.00 UTC on 26 August to 08.00 UTC on the 27th. Bookmark for updates and direct link to Club Log's OQRS.

VHF+ UHF+ MICROWAVE NEWS by Mike Bosch ZS2FM 21 August 2016 


HOW DIFFICULT IS IT TO WORK DX ON HF VERSUS VHF AND ABOVE? – F2 propagation on HF is seasonal and varies during the day, and when the solar activity is high then DX contacts are very easy to make, even with low power and a piece of wire thrown into a tree. But when the MUF drops then it really becomes a difficult task for smaller stations. EME on the other hand has been the most challenging mode in earlier days that required sophisticated equipment and antenna arrays on VHF, UHF and SHF, which is only possible when both stations can see the Moon. Digital communications have made it a lot easier with lower power and single Yagis. The EME challenge now lies in the mid-microwave spectrum. Long distance terrestrial DX operation on VHF, excluding F2 and TEP propagation, is currently the most difficult to achieve, while the best distance recorded so far on 144 MHz and 432 MHz is 4158 km over the Pacific Ocean via Tropo Ducting. The challenges on VHF and above are there for the more serious amateurs to take up, break existing records and advance amateur radio. 

TROPO DUCTING SEASON STARTS ACROSS INDIAN OCEAN – The Tropo Ducting season across the Indian Ocean usually starts during the month of August and stretches to October, and again during the month of February depending on weather conditions. These openings via Tropo Ducting have been recorded between the East Coast of South Africa and Reunion Island on 144 MHz and 432 MHz on both analogue and digital. It all started on 14 August 2008 when Glenn ZS2GK heard the FR5DN beacon from Reunion Island, and established contact with Phil on 144,401 MHz SSB and FM, a distance of 2875 km. The next year in September they worked each other again on 144 MHz SSB and FM as well as JT65b On 9 February 2010 Andre ZS2ACP established 144 MHz JT65b record with FR5DN over a distance of 3247 km, and on 7 October 2015 Andre ZSBK set up a SSB record with FR5DN over 3245 km. On 11 September 2011 Derek ZS5Y worked FR5DN for a first on 432 MHz digital and repeated a contact on 144 MHz. During this period a South African 103 MHz FM station was copied in Reunion Island at good strength.. During the interim period contacts were also made with Reunion Island by Peter ZS2ABF, John ZS2AH, Dave ZS5DJ and Lee ZS5LEE. The FR5DN beacons are currently operating on 144,4180 MHz JT65b for Tropo tests beamed at RSA, and 144,4220 MHz JT4g for TEP tests. 

NEW DISTANCE RECORD ON 47 GHz BETWEEN CANADA & USA – A new distance record was set on 47 GHz (6 mm) between Whiteface Mountain in New York at FN34bi and on Mont Tremblant in Quebec at FN26rf. The distance was calculated at 215 km, a new Canada-USA record on the band. Congratulations to N1JEZ, KT1J, VE2UG and VE3FN. The South African record on 47 GHz stands at 21,2 km and was established in 1990 on FM by ZS6AOU and ZS6BMS. 

COLD WEATHER AFFECTED VHF ACTIVITY – Jaco Cronje, ZR6CMG reports: “Last night the 16th August there were three stations active in Gauteng on 144,300 MHz SSB, ZS6UB and ZS6UD in Kempton Park and ZR6CMG at Pretoria North. ZS6UB and ZS6UD were having a QSO on vertical polarization and we were barely able to have a QSO between Pretoria North and Kempton Park. We then moved over to horizontal Yagi's and were able to have 5/9+ QSO's and were active till 21:00 CAT with very good conditions on 2 metres. We are reminding every one in Gauteng to come and join us on Tuesday and Thursday evenings from around 19:30 CAT on VHF and on Saturdays and Sundays from around 06:00 CAT. Carl ZS6CBQ is hosting the VHF net on 144,300 MHz SSB from Krugersdorp with regular contacts between ZS6 and stations in Division 4. Hope to hear all of you on VHF this week.”  

EARTH-LIKE PLANET ORBITING PROXIMA CENTAURI – The European Southern Observatory (ESO) is reportedly set to announce the discovery of a new “Earth-like” planet at the end of August. The unnamed planet is thought to have liquid water on its surface. The as yet unnamed planet orbits the small Proxima Centauri star, which, other than our Sun, is the closest star to Earth, located only 4,25 light years away. The exoplanet is located in the so-called “Goldilocks or habitable zone,” where it orbits the red star at a distance that would be favourable to having liquid water on the surface, which is vital for supporting life.

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.
