You are listening to ZS6SRL. Stay tuned for more details on these and
other important and interesting news items.

ARRL/TAPR DIGITAL COMMUNICATIONS CONFERENCE

Aficionados of digital communications are gearing up for the 29th
annual ARRL/TAPR Digital Communications Conference (DCC), September
24-26 near Portland, Oregon. The ARRL/TAPR DCC is an international
forum for radio amateurs to meet, publish their work and present new
ideas and techniques. Presenters and attendees will have the
opportunity to exchange ideas and learn about recent hardware and
software advances, theories, experimental results, and practical
applications.

The DCC is for all levels of technical experience - not just for the
expert. Not only is the three day conference technically stimulating,
it is a weekend of fun for all who have more than a casual interest in
any aspect of amateur digital electronics and communications;
introductory sessions are scheduled throughout the conference to
introduce new technical topics for both beginners and experts. Topics
at the DCC include, but are not limited to: Software defined radio
(SDR); digital voice (D-STAR, P25, WinDRM, FDMDV, G4GUO); digital
satellite communications; Global Position System (GPS); precision
timing; Automatic Position Reporting System (APRS); short messaging (a
mode of APRS); Digital Signal Processing (DSP); HF digital modes;
Internet interoperability with Amateur Radio networks; spread spectrum;
IEEE 802.11 and other license-exempt systems adaptable for Amateur
Radio; using TCP/IP networking over Amateur Radio; mesh and
peer-to-peer wireless networking; emergency and Homeland Defense backup
digital communications; using Linux in Amateur Radio; updates on AX.25,
and other wireless networking protocols.

SAT NETWORK

SA AMSAT has introduced SAT NETWORK, a regular discussion on satellite
on an INTECNET basis. The first SAT NETWORK will discuss the payload
options for the proposed SA AMSAT payload. It will be on the air on
Sunday 29 August 2010 at 19:30. John Williscroft, ZS6EF, will introduce
the subject with a presentation on an imaginary satellite and its multi
payloads built on the back of fold-out solar panels. The idea is to set
the scene for a useful discussion. You are invited to join the
discussion. By courtesy of the SARL, SAT NETWORK will be facilitated by
the same team as the President's Net and Intecnet on a repeater in the
Cape Town area, the Eastern Cape repeater network, Durban and Gauteng.
Marten, ZS6ZY, will relay ob 3 718 kHz and Chris, ZS6FCS, will take
care of Echolink and the Webcast.

SO67 OPERATIONAL ON ALMOST A DAILY BASIS

SO67 will be operational over South African on almost a daily basis.
The availability over South Africa is somewhat limited due the current
image downloading schedule. Details are on www.amsatsa.org.za.

WHO SAYS CHRISTMAS COMES ONLY ONCE A YEAR?

For Fred Scheepers, ZS1FCS, it came early this when he was the lucky
winner at the Cape Town Radio Technology in Action 2010 event of a
surprise package donated by Kobus Conradie, ZS1K, of Let's Play Radio.
Kobus donated a Yaesu FT60E, Twin-band Wide Receive Handheld
Transceiver. The radio valued at R1 900 was one of the many prizes in
the attendance draw. Attending a RTA can be more than fun, it could be
profitable. Thanks to Kobus and congratulations to Fred.

ANOTHER LOOK AT PLT REGULATIONS

Towards the end of last year, ICASA technical staff finalised the PLT
regulations and submitted them to the ICASA board for approval and
publication in the Government Gazette. From the discussion at the SABS
TC73 committee dealing with EMC matters held last week it appears that
Workgroup 6 who originally dealt with PLT will have an opportunity to
relook at the draft before it will be resubmitted to the ICASA Board.
The delays were brought about by changes on the ICASA Board with the
designated councillor having retired. The SARL is represented on TC73
and our representative is the convener of workgroup 6. The current
draft, while not including all the SARL proposals, includes a
reasonable mitigation clause should interference affect HF users in an
area where PLT is employed.

PROPAGATION REPORT

Hannes Coetzee, ZS6BZP, reports that the solar activity is still at low
levels. The sun is nearly blank of sunspots and the current streak of
daily spots which stands at 53 may soon come to an end. The effective
sunspot number is expected to be less than 25 for the coming week.

20 m will provide the best opportunities for DX followed by 40 m.
Conditions to India will be good from the late afternoons till after
sunset. During sunset it will be good towards Europa. Contacts with the
USA are still challenging. Contacts with Australia and New Zealand are
possible at sunrise on 20 m and on 40 m after sunset. Weak 15 m
openings to Brazil and South America are possible during the
afternoons.

For the CW and digital enthusiasts 30 m may be very rewarding with
openings to many parts of the world.

Locally is 40 m the work horse for contacts around the country with 30
m also being very useful for contacts over the longer distances. 80 m
will be best during the early mornings, late afternoons and during the
evenings as well as over the shorter distances.
