To celebrate World Radio Day, the SARL is hosting the 2023 WRD QSO Party
running from 17:00 to 21:00 UTC on Monday 13 February. Because parts of t
he country will experience blackouts, it has been decided to run the act
ivity for four hours. The QSO Party is a phone activity on 80 metres and t
he exchange is your name, the radio station you listen to and your grid
locator. Submit your log sheet, available on the Contest page on the Le
ague website, by 21:59 UTC on Saturday 18 February to [email protected]
.za (mailto:[email protected]) . Your 2023 WRD Certificate will be e-m ailed to you.

SARL COUNCIL NEWS

Council has received a letter of resignation from Cliff Smyth, ZS6BOX th
e Honorary Treasurer of the League. Council understands that his decision
is for personal and health reasons. In his letter Cliff has committed to
assisting his successor with all the help needed to ensure a smooth trans ition in the management of the League's financial affairs. Council will ap point a successor to Cliff as Honorary Treasurer in due course.

The Council thanks Cliff for his many years of outstanding dedication and
diligent service to the League and his commitment to the Amateur Radio se rvice and to his fellow amateurs. We wish Cliff good health and continued
enjoyment of his hobby, his family and Friends.

INTERFERENCE FROM SOLAR INSTALLATIONS

As the South African public are realising that they are on their own and f acing the many challenges of load sheading, self-generating electricity
by households and businesses has become the norm. Generally, Radio Ama
teurs should not experience interference on HF or VHF from properly instal
led solar power installations but unfortunately it does occur when unquali
fied people do not install the system properly and use poor quality invert
ers and solar maximisers. Often fitting ferrite beads and basic filters wi
ll solve the inference problem.

By design solar installations are not expected to radiate radio frequencie
s (RF) and cause interference as the necessary circuits suppressing any RF
radiation should be included in the design. There however are suppliers t
hat will install equipment of inferior quality. Solar installers are expe
cted to issue Certificates of Compliance (COC), but these certificates g enerally only cover the electrical installation.

If a neighbour installs a solar system and it kills HF, there are two ap proaches. Point out to him or her that the installation is causing radio i nterference and that he should insist that his installer sorts out the pro blem. If that fails, it is necessary to send a written complaint with de
tails of the interference to the Manager of the local ICASA office. ICASA
is fully equipped to do the necessary test and advise the owner of the in stallation to have the problem seen to or switch off his system.

The addresses of the local ICASA managers can be found on www.sarl.org.za/ public/licences/licences.asp. Please copy your letter of complaint to the
SARL at [email protected] (mailto:[email protected]) , as well
as to Chris, ZS6GM at [email protected] (mailto:[email protected]) an
d keep the SARL informed of progress of the complaint.

You are listening to a news bulletin of the South African Radio League.

TECHNOLOGY DEVELOPMENT

Are you keen on technology development? AMSAT SA may just have the right c hallenge for you. The AfriCUBE development team is being expanded to tackl
e interesting supplementary and operational projects. AfriCUBE and its pre decessor, Kletskous have been a long time in finalising but that is the
name of the game if you do not go out shopping and buy everything in kit
form and just assemble it. Almost every part of the projects were locally
developed and engineered and in the process many people have facilitated
and grown their own technical abilities, adding to South Africa's intel lectual capital.

Volunteers are needed for the final development of a power supply and cont
rol unit, several sensor projects for the educational part of the satell
ite and ground control equipment. Here is an importunity to contribute to
amateur radio technology and develop your own technical skills. The proj
ect team meets regularly on alternate Monday evenings on the BlueJeans vid
eo conference platform and a few times a year for a Saturday face to face
meeting in Midrand. A face-to-face review meeting is planned for the end
of February. If you are interested, now is a good time to send an e-mai
l to [email protected] (mailto:[email protected]) with your interest
and contact details. We will call you.

ZS SOTA - 20 YEARS - TIME TO CELEBRATE

SOTA in ZS has now been active for 20 years. It was decided that 18 Februa
ry would be a good day to celebrate the 20th anniversary. This day is open
to all radio amateurs to join in the fun of either activating a summit or
chasing the activators. Activators are requested to post their proposed t
imes on the ZS-SOTA WhatsApp Group and the Facebook page. A certificate of
participation will be issued.

DIE WERELD RADIO DAG QSO PARTYTJIE OP 13 FEBRUARIE

Die tema vir die 12de uitgawe van die Wêreld Radio Dag, wat op 13 F
ebruarie 2023 gevier word, is "Radio en Vrede." Lees mee
r by www.unesco.org/en/days/world-radio/radio-peace en luister na LM Break

Om Wêreld Radio Dag te vier, bied die SARL die 2023 WRD QSO-partytj
ie aan wat op Maandag 13 Februarie van 17:00 tot 21:00 UTC plaasvind. Omda
t dele van die land krag onderbrekings sal ervaar, is besluit om die akt iwiteit vir vier uur te laat loop. Die QSO Partytjie is 'n foon aktiwiteit
op 80 meter en die uitruiling is jou naam, die radiostasie waarna jy lu
ister en jou ruitvierkant. Dien jou logstaat in, beskikbaar op die Kompe tisie-bladsy op die Liga-webwerf, teen 21:59 UTC op Saterdag 18 Februari
e by [email protected] (mailto:[email protected]) . Jou 2023 WRD-s ertifikaat sal per e-pos aan jou gestuur word.

SARL RAAD NUUS

Die Raad het 'n bedankingsbrief ontvang van Cliff Smyth, ZS6BOX die Ere- tesourier van die Liga.
Die Raad verstaan dat sy besluit gebaseer is op persoonlike en gesondheids redes is. In sy brief het Cliff hom daartoe verbind om sy opvolger by te s
taan met al die hulp wat nodig is om 'n gladde oorgang in die bestuur van
die Liga se finansiële sake te verseker. Die Raad sal mettertyd 'n o
pvolger vir Cliff as Ere-tesourier aanwys.

Die Raad bedank Cliff vir sy baie jare van uitstaande toewyding en ywerige
diens aan die Liga en sy lojaliteit aan die Amateur Radio diens en mede a mateurs. Ons wens Cliff goeie gesondheid en volgehoue genot van sy stokper djie, sy familie en vriende toe.

STEURINGS VAN SONKRAG-INSTALLASIES

Aangesien die Suid-Afrikaanse publiek besef dat hulle op hul eie is en die
talle uitdagings van beurtkrag in die gesig staar, het self-opwekking v
an elektrisiteit deur huishoudings en besighede die norm geword. Oor die a lgemeen behoort Radio Amateurs nie steurings op HF of BHF van behoorlik ge ïnstalleerde sonkrag-installasies te ervaar nie, maar dit kom ongel
ukkig voor wanneer ongekwalifiseerde mense nie die stelsel behoorlik insta lleer nie en swak kwaliteit omsetters en sonkrag-maksimeerders gebruik. Di kwels sal die pas van ferriet-krale en basiese filters die steurings probl
eem oplos.

Deur ontwerp word daar nie van sonkrag-installasies verwag om radiofrekwen
sies (RF) uit te straal en steuring te veroorsaak nie, aangesien die str oombane wat enige RF-straling onderdruk by die ontwerp ingesluit word. Da
ar is egter verskaffers wat toerusting van minderwaardige gehalte sal inst alleer. Daar word van sonkrag-installeerders verwag om Sertifikaat van Vol doening (COC) uit te reik, maar hierdie sertifikate dek gewoonlik net di
e elektriese installasie.

As 'n buurman 'n sonkrag stelsel installeer en dit maak HF dood, is daar
twee benaderings. Wys hom of haar daarop dat die installasie radiosteurin
gs veroorsaak en dat hy moet aandring dat sy installeerder die probleem ui tsorteer. Indien dit misluk, is dit nodig om 'n skriftelike klagte met b esonderhede van die steurings aan die Bestuurder van die plaaslike OKOSA-k antoor te stuur. OKOSA is ten volle toegerus om die nodige toetse te doen
en die eienaar van die installasie te adviseer om die probleem te laat na
sien of sy stelsel af te skakel.

Die adresse van die plaaslike OKOSA-bestuurders kan gevind word op www.sar l.org.za/public/licences/licences.asp. Kopieer asseblief jou klagte brief
aan die SARL by [email protected] (mailto:[email protected]) ,
asook aan Chris, ZS6GM by [email protected] (mailto:[email protected]
) en hou die SARL op hoogte van die vordering van die klagte.

Jy luister na ʼn nuus uitsending van die Suid-Afrikaanse Radioliga.

TEGNOLOGIE-ONTWIKKELING

Is jy lus vir tegnologie-ontwikkeling? AMSAT SA het dalk net die regte uit daging vir jou. Die AfriCUBE-ontwikkelingspan word uitgebrei om interessan
te aanvullende en operasionele projekte aan te pak. AfriCUBE en sy voorgan
ger, Kletskous was al lank besig om te finaliseer, maar dit is die naa
m van die speletjie as jy nie inkopies gaan doen en alles in self-bou vorm
koop en dit net monteer nie. Byna elke deel van die projekte is plaaslik
ontwikkel en ontwerp en in die proses het baie persone hul eie tegniese v ermoëns gefasiliteer en ontwikkel, wat tot Suid-Afrika se intellekt
uele kapitaal bygedra het.

Vrywilligers word benodig vir die finale ontwikkeling van 'n kragtoevoer-
en beheereenheid, verskeie sensor projekte vir die opvoedkundige deel v
an die satelliet en grondbeheer-toerusting. Hier is 'n belangrikheid om by
te dra tot amateur radio tegnologie en jou eie tegniese vaardighede te on twikkel. Die projekspan vergader gereeld op alternatiewe Maandagaande op d
ie BlueJeans-videokonferensie platform en 'n paar keer per jaar vir 'n Sat erdag-aangesig-tot-aangesig-vergadering in Midrand. 'n Aangesig-to
t-aangesig hersienings vergadering word vir einde Februarie beplan. Indien
jy belangstel, is dit nou 'n goeie tyd om 'n e-pos te s
tuur na [email protected] (mailto:[email protected]) met jou belangs telling en kontakbesonderhede. Ons sal jou bel.

ZS SOTA - 20 JAAR - TYD OM TE VIER

SOTA in ZS is nou al 20 jaar aktief. Daar is besluit dat 18 Februarie 'n g

wees. Dit is die grootste amateur radio geleentheid van die jaar in die K
aap, moet dit nie misloop nie.

HF VOORTPLANTINGSVOORSPELLING

Hannes Coetzee, ZS6BZP, berig dat die verwagte sonaktiwiteitsvlak laag
tot gematig gaan wees. Tans is daar tien sonvlekke met eenvoudige tot gev orderde magnetiese samestellings sigbaar. Daar is 'n hoë waarskynlikh
eid vir die voorkoms van C-klas en M-klas fakkels. Diegene wat hulle eie f rekwensievoorspellings wil doen, kan 'n verwagte effektiewe sonvlektelli
ng van 155 vir die week gebruik. Radio amateurs kan goeie DX openinge op d
ie 10 tot 30 m bande verwag. 6 m kan dalk ook aangenaam verras. Besoek ger
