SARL HF PHONE CONTEST THIS AFTERNOON

The first of the three SARL HF Contests, the HF Phone Contest, is on
the air this afternoon from 13:00 to 16:30 UTC with activity on 20, 40
and 80 metres. See how many zones you can work per band and how many
stations on all three bands. You can participate as a single operator
single band station, a single operator all band station, a multi
operator single band station or a multi operator all band station.
Individual competitors and club stations are encouraged to compete. The
exchange is a RS report and a consecutive serial number starting at
001.

There are three SARL trophies up for grabs in the phone contest, but
you stand a chance to win more trophies if you participate in all three
contests. The rules are too long to publish in SARL News, so look on
page 34 of the 2017 SARL Blue Book for all the information. Do it
before the contest starts.

ANNUAL YOTA 2017 SUMMER EVENT

Yesterday Saturday 05 August, the annual IARU Region 1 Youngsters on
the Air (YOTA) event kicked off with 80 youngsters from 30 different
IARU Region 1 Member Societies including a team from Japan. The YOTA
week is being hosted by the RSGB and the event takes place at Gilwell
Park, Chingford, Waltham Abbey, London, the headquarters of UK
Scouting.

The youngsters will be having fun with amateur radio, enjoying
workshops, optimising their skills in electronics with kit construction
and antenna building, SOTA activations, direction finding, and making
many new international friends during the famous inter-cultural evening
where everyone brings food and drinks from their home countries. With
excursions to Bletchley Park, the National Radio Centre and the Science
Museum in London, it is certainly going to be an eventful week.

On Tuesday evening 8 August, the youngster will have an opportunity to
talk to astronaut Paulo Nespoli, IZ0JPA, on the International Space
Station using amateur radio. The ISS contact will provide the
youngsters with an unforgettable experience in space communications via
amateur radio.

If you would like to have a QSO with one of the youngsters, listen out
for the multi-station special event station GB17YOTA which will be on
air 24/7 on most bands using several different modes.

complications, the 2017 ZS9V Robben Island DXpedition has been moved
from 9 to 13 August to the International Lighthouse weekend of 19 and
20 August. The team will be running two SSB stations, one will be
capable of at least 20, 15 and 10 m operation and the other of at least
80 and 40 m operation. Further information on the DXpedition will be

AMSATSA/SARL WORKSHOP TO FOCUS ON TAKING SDR TO A NEW LEVEL

The AMSAT SA/SARL workshop, to be held on Saturday 19 August at the
SARL National Amateur Radio Centre at Radiokop Roodepoort, will focus
on how to get more out of Software Defined Radio, and will take
participants to another level in Amateur Radio activity.

The workshop will be presented in two sessions. Session one will deal
with the VHF SDR dongle and how to have more fun, such as listening to
satellites, receiving weather satellites pictures, and astronomy
projects. The second session will discuss a HF Dongle and the SARL HF
Noise floor monitoring project, with details and a demonstration of how
to automate this and how to build an autonomous system using a
raspberry Pi.

maritime mobile net. To help your thought process for the Radio ZS
Antenna Design Competition, there are two articles to read - Hannes,
ZS6BZP, discusses the Double-Delta Loop Receive Antenna for the Low

BEACON NEWS

This week saw the full activation of two new Manned Experimental
Propagation Tests (MEPT) beacons in divisions three and four. Firstly,
Dennis Green activated ZS4BFN but switched to his own callsign ZS4BS
after a few hours. Dennis has already been spotted on 60 metres in most
divisions as well as some DX spots on 40 and 20 m. The second beacon
was activated by Pieter Gaybba, ZS3PG, at Vanderkloof under the
callsign ZS3ZU. He was recently spotted 10 045 km away on 250 mW by
SM4GRP in Sweden. A huge thank you to these amateurs for their
contributions to the propagation project.

Amateurs who would like to assist the Beaconeers, especially from
division two, can contact Leon Uys, ZR6LU, on e-mail at
leo...@gmail.com or WhatsApp on 082 573 5580.

DIGITAL MOBILE RADIO WORKSHOP

The SA Digital Repeater Sub-Committee (SADRS) is running an event at
the National Amateur Radio Centre from 10:00 to 17:00 CAT on Saturday

SOLAR CYCLE 24

Jim Kennedy, KH6/K6MIO reports that the current Solar Cycle 24
continues its downward trend. For several years now, the Sun's northern
and southern hemispheres continue to have separate minds about their
relative rates of descent. The southern hemisphere index is now rather
close to zero, while the northern index, though tracking downward, has
started from a higher level.

In the meantime, during March 2017, there were no sunspots for 16 days
in either hemisphere. There was a total of 23 days with fewer than 30
daily sunspots. All the indications are that we will be seeing even
longer periods of blank Sun over the next few years. There continue to
be expectations that the upcoming Cycle 25 will be noticeably weaker
than Cycle 24. It seems likely that, when it does clearly begin to move
upward from the probably long minimum, it will be slow in rising.

It is interesting to compare Cycle 12 (1878 - 1890) with Cycle 24.
Although Cycle 12 was somewhat weaker than Cycle 24, it shows a lot of
the same general characteristics of Cycle 24 rise and fall profile. It
is reasonable to think that the official Cycle 24 minimum will occur
sometime in 2020 or 2021. Many solar professionals are predicting Cycle
25 to have an overall maximum in the 60s. That would be nearly half of
Cycle 24 maximum.

PROPAGATION REPORT

Hannes Coetzee, ZS6BZP, reports that the solar activity is expected to
be at low levels. There is currently only a single sunspot visible
which poses little threat for solar flares. If you want to do your own
frequency predictions, the expected effective sunspot number for the
week will be around six. The 20 and 30 m bands will provide lots of DX
fun. 60 m will be the best band during day time for shorter distances,
and local contacts. Please visit the website spaceweather.sansa.org.za
for further information.

Finally, a diary of some upcoming events:

5 to 12 August - the Region 1 YOTA Summer Camp with call sign GB17YOTA

To conclude our bulletin, a quick overview of our main news item:

The first of the three SARL HF Contests, the HF Phone Contest is on the
air this afternoon from 13:00 to 16:30 UTC with activity on 20, 40 and
80 metres. See how many zones you can work per band and how many
