DUE DATE FOR THE RENEWAL OF RADIO FREQUENCY SPECTRUM LICENCES EXTENDED

Pretoria, 30 March 2020 - Given the state of national disaster and the c
urrent 21-day lockdown to curb the spread of the COVID-19 pandemic, ICAS
A has decided to extend the validity period of existing radio frequency sp
ectrum licences in line with Regulation 10 of the Radio Frequency Spectrum
Regulations.

In terms of the Regulations, the due date for the renewal of radio frequ
ency spectrum licences is 31 March annually. The Regulations further provi
de that failure to pay the prescribed licence renewal fee by the due date
(i.e. 31 March annually), will cause the expiry of the radio frequency
spectrum licence immediately on the next calendar day that marks the begi
nning of the new financial year.

In this regard, ICASA has resolved to grant all radio frequency spectrum
licence holders an extension to renew their licences by no later than the
30th of June 2020.

Do not wait until 30 June 2020 to pay your licence fees - do it now! The L
icences fees are available on the front page of the SARL web and in SARL C
ommunication of 25 March 2020 and SARL News for 28 March 2020.

THE APRIL 2020 RADIO ZS AVAILABLE TO ALL

The Council has decided that the April 2020 issue of Radio ZS is available
for members and not yet members of the SARL. Click on the link on the fro
nt page of the League website to download a copy. Read on page 10 and 17 a
bout My Project and how to win a membership to the SARL. On page 11 you ca
n read about SARAH or Southern African Radio Active Ham.
LOCKDOWN JAILBREAK!

The world is in lockdown and slowly going mad. A jailbreak seems like a go
od idea and as radio amateurs we have an advantage - a creative im
agination and a willingness to tinker!

Let us pretend a little.... We are under house arrest; our homes bei
ng monitored by a remote electronic surveillance system and the access con
trol governed by electronic key codes! We can only escape by working toget
her. Once you read this, you will be on the inside track to freedom, w
e once took for granted! SARAH is our inside agent and she will be giving
out electronic key codes. A key code is simply a 4-letter combination (no
numbers, spaces, or special characters) and it will allow you to disa
ble the surveillance remotely.

Unfortunately, you cannot use the key codes SARAH gives you on your own
home - it needs to be used by someone else. You can, however,
use codes given out by other people. At this stage, it is unclear just
how many key codes are needed to disable your security surveillance but g
et as many as you can!

own Jailbreak! There is also a PDF document telling you about this activit
y at www.sarah.org.za/lockdownGame.pdf

AMSATSA REPORTS GOOD PROGRESS WITH AFRICUBE

AMSATSA held its regular online progress meeting this past Wednesday. Duri
ng the past few weeks, progress was made on all fronts. The transponder
was tested on the air and an actual contact was made through the transpon
der. Hannes Coetzee, ZS6BZP installed the transponder on the tower at hi
s house and made a contact with Keith Laaks, ZS6TW. While it was only ov
er a few kilometres distance, the importance of the contact was that the
re was no interference and the audio quality was good.

This past week Anton Janovsky, ZR6AIC has worked on the software and thr
ough a complicated link managed to upload and install newer software remot
ely. "Anton connected to my computer and took over the machine usi
ng TeamViewer and then connected via Wi-Fi to the transponder on my tower
," Hannes, ZS6BZP said. "In normal times we would have
simply exchanged a memory stick, but in abnormal times one has to resor
t to unconventional ways of doing things".

Further updates will be uploaded this weekend with more testing of the tra
nsponder. The next step is to open the testing to local radio amateurs. Fu
ll details will be announced on SARL News and on the AMSAT SA Web. The ful
l AfriCUBE development story is available on www.amsatsa.org.za.
The review meeting was also updated with the other components of AfriCUBE.
The space frame is complete, the PC boards for the solar panels have be
en designed and will be manufactured as soon as the lockdown is over. Work
is continuing on the antenna and solar panel deployment and a further pro
totype will be manufactured as soon as South Africa returns to normal work
.. The electronic power supply unit is complete. A new interface between th
e Raspberry Pi and the processor has been designed and the circuit board l
aid out.

IARU NOISE MONITORING GROUP DISCUSSED REFINEMENTS TO THE PROJECT

During a two-hour online meeting last Monday, the IARU Noise Monitoring
group discussed various refinements to the noise monitoring project. The
aim is to derive a worldwide data format, so that the collected informa
tion can be shared.

The DARC group presented the results of their first 10 stations installed
in Germany and compared the results between rural areas, low-density su
burbs and high-density suburbs. The SARL group has for some time been disc
ussing various time frame options and the bandwidth of each segment. Curre
ntly, each measurement segment covers 1 MHz of the spectrum from 1 to 30
MHz.

While the process in some parts of Europe is different, the SARL group b
elieves that international compatibility can be achieved. The SARL Noise M
onitoring group will meet over the next two weeks to finalise the format a
nd make recommendations on how to move forward. The ultimate aim is to dev
elop specifications and make complete units available for installation on
sites around the country.
PROPAGATION REPORT

Hannes Coetzee, ZS6BZP, reports that the solar activity is expected to
remain at low levels. Currently there is one small sunspot region with a
simple magnetic configuration and no flaring activity is expected. If you
want to do your own frequency predictions, the expected effective sunsp
ot number for the week will be around one. With the recent equinox, the
15 to 30 m bands will, especially late afternoon, provide some good D
X fun. Early afternoon there may also even be some surprise 10 m openings.

BETAAL DATUM VIR DIE HERNUWING VAN RADIO FREKWENSIE SPEKTRUM LISENSIES UIT
GESTEL

Pretoria, 30 Maart 2020 - In die lig van die toestand van nasionale ramp
e en die huidige 21-dae-inperking
om die verspreiding van die COVID-19-pandemie te bekamp, het OKOSA 'n be
sluit geneem om die geldigheidstydperk van bestaande radio frekwensie spek
trum lisensies te verleng in ooreenstemming met Regulasie 10 van die Radio
Frekwensie Spektrum Regulasies.

Ingevolge die Regulasies is die sperdatum vir die hernuwing van radio frek
wensie spektrum lisensies jaarliks 31 Maart. Die regulasies bepaal verder
dat versuim om die voorgeskrewe fooi vir die hernuwing van die lisensie t
een die sperdatum (d.w.s 31 Maart jaarliks) te betaal, sal lei tot die v
erstryking van die radio frekwensie spektrum lisensie onmiddellik op die v
olgende kalenderdag wat die begin van die nuwe finansiële jaar is.

In hierdie verband het OKOSA besluit om alle houers van radio frekwensie s
pektrum lisensies 'n uitbreiding te gee om hul lisensies te hernu teen nie
later nie as 30 Junie 2020.

Moet nie wag tot 30 Junie 2020 om jou lisensiegeld te betaal nie - doen di
t nou! Die lisensiegelde is beskikbaar op die voorblad van die SARL-web so
wel as in SARL Kommunikasie van 25 Maart 2020 en SARL Nuus vir 28 Maart 20
20.

DIE APRIL 2020 RADIO ZS BESKIKBAAR VIR ALMAL

Die Raad het besluit dat die April 2020 uitgawe van Radio ZS beskikbaar is
vir lede en nog nie lede van die SARL. Klik op die skakel op die voorblad
van die Liga-webwerf om 'n eksemplaar af te laai. Lees op bladsy 10 en 17
oor My Projek en hoe om â-˜n lidmaatskap van die SARL te wen. Op bl
adsy 11 kan jy lees oor SARAH of die South African Radio Active Ham.

INPERKING TRONK BREEK!

Die wêreld is ingeperk en word stadig maar seker mal. Om by die tronk
uit te breek lyk na 'n goeie idee en as radio amateurs het ons 'n voordee
l - 'n kreatiewe verbeelding en 'n gewilligheid om te peuter!

Laat ons 'n bietjie voorgee... Ons is onder huisarres; ons huise word deur
'n eksterne elektroniese toesig stelsel gemonitor en die toegangsbeheer w
ord beheer deur elektroniese sleutelkodes! Ons kan net ontsnap deur saam t
e werk. Sodra jy dit gelees het, sal jy op die regte pad wees na vryheid
wat ons as vanselfsprekend aanvaar! SARAH is ons agent aan die binnekant
en sy gee elektroniese sleutelkodes uit. 'n Sleutelkode is bloot 'n kombi
nasie van vier letters (geen syfers, spasies of spesiale karakters) en d
it stel jou in staat om die toesig te deaktiveer.
Ongelukkig kan jy nie die sleutelkodes gebruik wat SARAH vir jou gee, op
jou eie huis gebruik nie - dit moet deur iemand anders gebruik word. Jy k
an egter kodes gebruik wat deur ander mense gegee is. Op hierdie stadium i
s dit onduidelik hoeveel sleutelkodes nodig is om jou sekuriteits bewaking
uit te skakel, maar kry soveel as moontlik!

Besoek www.sarah.org.za/, registreer en vind meer uit oor die Inperking
Tronk Uitbreek! Daar is ook 'n PDF-dokument wat jou oor hierdie aktiwitei
t vertel, by www.sarah.org.za/lockdownGame.pdf

AMSATSA RAPPORTEER GOEIE VORDERING MET AFRICUBE

AMSATSA het die afgelope Woensdag sy gereelde aanlyn vorderings vergaderin
g gehou. Gedurende die laaste paar weke is vordering op alle fronte gemaak
.. Die transponder is op die lug getoets en 'n werklike kontak is gemaak de
ur die transponder. Hannes Coetzee, ZS6BZP het die transponder op die to
ring op sy huis geïnstalleer en 'n kontak met Keith Laaks, ZS6TW ge
maak. Terwyl dit net oor 'n paar kilometer afstand was, die belangrikhei
d van die kontak was dat daar geen steurings was en die klank kwaliteit wa
s goed.

Hierdie afgelope week het Anton Janovsky, ZR6AIC aan die sagteware gewer
k en deur 'n ingewikkelde skakel daarin geslaag om meer moderne sagteware
op te laai en te installeer op â-˜n afstand. "Anton het aan my reke
naar gekoppel en die masjien met TeamViewer oorgeneem en dan via Wi-Fi met
die transponder op my toring verbind," het Hannes, ZS6BZP gesê.
"In normale tye sou ons eenvoudig 'n geheue stokkie geruil het, maar in
abnormale tye het mens onkonvensionele maniere om dinge te doen".

Verdere bewerkings sal die naweek opgelaai word met meer toetsing van die
transponder. Die volgende stap is om die toets oop te maak vir plaaslike
radio amateurs. Volledige besonderhede sal aangekondig word op SARL Nuus
en op die AMSAT SA web. Die volledige AfriCUBE ontwikkeling verhaal is op
www.amsatsa.org.za beskikbaar.

Die hersienings vergadering is ook met die ander komponente van AfriCUBE o
pgedateer. Die ruimte raam is voltooi, die PC borde vir die son panele i
s ontwerp en sal vervaardig word sodra die inperking verby is. Werk gaan v
oort op die antenna en sonpaneel ontplooiing en 'n verdere prototipe sal v
ervaardig word sodra Suid-Afrika terugkeer na normale werk. Die elektronie
se kragvoorsiening eenheid is voltooi. 'n Nuwe koppelvlak tussen die Raspb
erry PI en die verwerker is ontwerp en stroombaan bord is uitgelê.

IARU GERAAS MONITERING GROEP HET AFRONDINGS AAN DIE PROJEK BESPREEK

Tydens 'n twee-uur aanlyn vergadering verlede Maandag, het die IARU Gera
as Monitering groep verskeie afrondings aan die geraas monitering projek b
espreek. Die doel is om 'n wêreldwye data formaat te bepaal sodat die
versamelde inligting gedeel kan word.

Die DARC-groep het die uitslae van hul eerste 10 stasies wat in Duitsland
geïnstalleer is, aangebied en vergelyk die uitslae tussen landelik
e gebiede, lae digtheid voorstede en hoë digtheid voorstede. Die SA
RL-groep het vir 'n geruime tyd verskeie tydraam opsies en die bandwydte v
an elke segment bespreek. Tans dek elke meting segment 1 MHz van die spekt
rum 1 tot 30 MHz.

Hoewel die proses in sommige dele van Europa anders is, glo die SARL-gro
ep dat internasionale verenigbaarheid bereik kan word. Die SARL Geraas Mon
itering groep sal oor die volgende twee weke vergader om die formaat te fi
naliseer en aanbevelings te maak oor hoe om vorentoe te beweeg. Die uitein
delike doel is om spesifikasies te ontwikkel en volledige eenhede beskikba
ar te maak vir installasie op terreine regoor die land.

HF VOORTPLANTINGSVOORSPELLING

Hannes Coetzee, ZS6BZP, berig dat die verwagte sonaktiwiteit vlak laag
gaan bly. Tans is daar slegs 'n enkele, klein sonvlekke met 'n eenvoudi
ge magnetiese samestelling sigbaar. Daar is nie 'n moontlikheid vir son fa
kkels nie. Diegene wat hulle eie frekwensie voorspellings wil doen, kan
'n verwagte effektiewe sonvlek telling van een vir die week gebruik. Met
die onlangse dag-en-nag-ewening kan radio amateurs veral laatmiddag goeie
DX openinge op die 15 tot 30 m bande verwag. Vroegmiddag mag daar selfs o
ok 'n paar 10 m openinge wees. Besoek gerus die webtuiste spaceweather.san
sa.org.za vir meer inligting.

Nou die Dagboek van Gebeure vir die volgende paar weke:

10 April - Goeie Vrydag
12 April - Paassondag
13 April - Familie dag
18 April - Wêreld Amateur Radio Dag en die Herfs QRP Naelloop
19 April - die ZS4 Naelloop
21 en 22 April - die Lyrids meteor stort

Om die bulletin mee af te sluit, â-˜n opsomming van ons hoof berig

Ingevolge die Regulasies is die sperdatum vir die hernuwing van radio frek
wensie spektrum lisensies jaarliks 31 Maart. Die regulasies bepaal verder
dat versuim om die voorgeskrewe fooi vir die hernuwing van die lisensie t
een die sperdatum (d.w.s 31 Maart jaarliks) te betaal, sal lei tot die v
