PRESIDENT'S NET AND INTECNET NEXT SUNDAY

The President's Net will be on the air next Sunday. Join Graham
Hartlett, ZS6GJH, at 19:00 for an update on the SARL and the various
activities planned for the next few months. Graham will also talk about
the SARL plans to promote ARDF - Amateur Radio Direction Finding - an
activity that is currently attracting a lot of attention from the youth
in Europe and the USA.

The President's Net will be followed at 20:00 CAT by the Intecnet with
Dr Pieter Kotzé as the guest speaker. His presentation is entitled:
'Implications of Living on a Giant Magnet'.

In this presentation various aspects of the Earth's magnetic field will
be discussed, its generation, as well as its influence on sophisticated
technology, especially during magnetic storms. HF radio communications
as well as GPS-based technologies are particularly adversely affected.
Reversals of the geomagnetic field and the protective role of the
magnetic field as well as the atmosphere for life on Earth will be
highlighted. Declination, the angle between true North and magnetic
North, is an important component of geomagnetism worldwide, but in
particular southern Africa. Its non-uniform variation with time is of
special interest to users of navigation maps.

The presentation slides can be downloaded in PDF format. Visit the SARL
web at www.sarl.org.za and click on ARMI.

Clubs wishing to book a link to the conference bridge should send the
telephone number and local repeater details to by
Friday this week.

PLT CONTINUES TO BE PUNTED BY VENDORS

This past week PLT was again the subject at a conference held in
Sandton. A new company which has been very active promoting PLT is
IPOWA. According to their website IPOWA is the exclusive local provider
of the world's leading broadband-over-Powerline (BPL) system. A proven,
cost-effective and robust route to rapid broadband deployment, iPOWA is
the last-mile solution for which utilities, ISP's, hotels, schools and
property developers have been waiting for. By leveraging existing
infrastructure and utilizing a unique plug 'n play system, iPOWA is the
key to high-speed access that works - fast.

Three of their representatives presented their case at Internetics 07,
a conference about IT and the internet, sponsored by Internet
Solutions.

iPOWA's approach has been somewhat different from their previous
presentation at a broadband conference a few weeks ago. This time they
are promoting it as the fixed line solution that powers the internet 15
times faster than ADSL and that besides the internet provides
opportunities for power management, meter reading, electricity demand
control to prevent black outs, security cameras and traffic management.

Problems such as interference to HF never entered into their
discussion. They however did admit that they are waiting for ICASA to
license PLT, which is the official name for BPL.

The interference issue of PLT and possible interim standards is on the
Agenda of Committee TC73, the SABS committee on EMC standards which
meets mid August. The SARL is keeping a close watch.

Log sheets must be submitted within 15 days after the contest and can
be sent by e-mail to or by snail mail to BARK, PO
Box 2105, Dennesig, 7601.

Monday 23 July is the closing date for log submissions for the SARL

The SARL HF Phone Contest will be run on Sunday 5 August 2007 starting
at 15:00 and ending at 18:30 CAT with activity on certain sections of
the 20, 40 and 80 metre bands. Participation can be as a single
operator, multi-operator or SWL, further sub-division is low power,
high power, all band, single band or my best hour. The exchange is a RS
report and a serial number.

Southern Africa is divided into 8 zones for this contest and
participants must try and work stations in each of these zones for
bonus points, further bonus points are obtained for working the same
station on all 3 bands.

The rules and log sheets are available in the 2007 SARL Contest Manual
at www.sarl.org.

PROPAGATION REPORT

Hannes Coetzee, ZS6BZP, reports that the expected solar activity will
be at very low levels. The geomagnetic field is expected to be quiet in
general while reaching active levels on 31 July. The expected Effective
Sun Spot number for the coming week will be less than 5.

20 m and 40 m will provide best opportunities for DX. There is a
possibility of 20 m openings towards India from about 15:30 CAT. 40 m
may open from 20:00 to Australia. From 17:00 there may be a 20 m
opening towards Europe. At about 16:00 short 20 m openings towards the
West Coast of the USA are possible. Otherwise contacts to the USA are
going to be very challenging. For the CW and digital enthusiasts it
will also be worth monitoring 10 MHz.

Locally 40 m is going to be the band to be on for the Boland ARC fun
contest with good propagation throughout South Africa till at least
16:00, depending on your location. Remember that HF always has the
capability to surprise you.

You will never know what you are missing unless you switch your rig on,
listen and also call CQ.
