SPECIAL ANNOUNCEMENT

It seems that the SARL web is having a problem with the acceptance and
forwarding of news items for the bulletin and that may be why there is
no news from clubs in this bulletin. We apologise for this
inconvenience. We trust that the webmaster will soon get rid of this
problem and that news will soon start to flow smoothly again.

In the news today:

SARL ANNOUNCES A REDUCTION IN RAE EXAM FEES

ITCHEN VALLEY RADIO CLUB BURSARIES AWARDED

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

SARL ANNOUNCES A REDUCTION IN RAE EXAM FEES

During the President's Net last Sunday SARL President Graham Hartlett
announced a substantial reduction in the RAE fees. The reduction has
been made possible as ICASA has agreed that in future the SARL, as the
national body for Amateur Radio, will be authorised to issue the RAE
certificate. Effective immediately, the registration fee for both the
class A and Class B examination will be an inclusive R300. There is an
additional reduction for students under the age of 25 who can prove
that they are full time students or learners. The fee will be R200. The
fee will include one re-write should the candidate fail the first
attempt at the examination, however no refunds will be considered.

The process for registering for the examination has also been
streamlined. Candidates can download the necessary forms from the SARL
website or request copies from the SARL administrator and after
completion fax or mail the completed forms and required documentation
to the SARL. It is important that candidates carefully follow the
checklist on the RAE registration form to ensure that all the required
documentation is submitted. Failing to do so may result in unnecessary
delays.

The SARL is currently working with ICASA on combining the RAE
certificate with the HAREC certificate as specified in the radio
regulations. Once this has been finalised, candidates who pass the
class A examination will receive a HAREC certificate which will be
valid for application of an amateur radio license in CEPT countries and
other countries which has contracted into the HAREC system. HAREC is
the acronym for Harmonised Amateur Radio Examination certificate. This
process may take a few weeks.

MORE FOR MEMBERS

Graham Hartlett also discussed the issue of more benefits for members.
He said that the Council had accepted the principle that members should
derive maximum benefit from their membership. As the National Body for
Amateur Radio, a number of services must be available to all radio
amateurs for which the SARL will in future charge an admin fee. He
cited the example of the upgrade process from ZR to ZS. The process
will be free for SARL members, but non-members will be charged an admin
fee of R100. The SARL will also relook at the various services on the
web and, where necessary, upgrade the website and increase the members
only content.

He said that not all changes will be made immediately but will be an
ongoing process over a period of time.

ITCHEN VALLEY RADIOCLUB BURSARIES AWARDED

The South African Amateur Radio Development Trust has awarded the three
YARP - Young People in Amateur Radio Programme - bursaries sponsored by
the UK Itchen Valley Radio Club. The successful candidates a Bongani
Mondlana, Nfumo Khoza and Suzette van Wyk. They will study for the
class A examination and write in October. Congratulations to the three
students, we wish them success in their studies.

BAND PLANS AND SPECTRUM MANAGEMENT

Due to the shortage of local news we include and item taken from WIA
News which is applicable to all radio amateurs world wide and which we
may well take note of. (Read SARL where WIA appears in the text).

Amateur Self-Regulation.

Amateurs use a wide variety of different modes. Within one amateur
band, activity can include CW, voice, satellite and EME activity, and
ATV. The best way of avoiding clashes is to set aside different band
segments for each of these activities, so that all amateurs can pursue
their interests without interference.

Amateur band plans are voluntary agreements, often known as
"Gentlemen's Agreements". They are sponsored by the WIA, but they are
for the benefit of all amateurs. Most amateurs, WIA members or not,
abide by the band plans because it makes sense to give everyone a fair
go.

Clashes still occur at times, and the usual reason is lack of awareness
of the band plans. Most amateurs are willing to change frequency if the
problem is explained to them politely.

Band plans should satisfy a number of conflicting criteria:

They should take local conditions into account, but they should be
consistent with international usage.

They should encourage spectrum efficiency, but they should also ensure
that all modes have their fair share of spectrum space.

They should take the popularity of each mode into account, while still
providing enough spectrum space for less popular activities. For
example, ATV requires far more bandwidth per operator than other modes;
and activities such as EME are of major importance regardless of the
number of stations involved.

Band plans must be flexible enough to adapt to changing needs, but they
tend to lose support if they are changed too often. The aim must be to
think ahead and to make sure that future options are not closed off.

On the VHF-UHF bands, three main groups a

CW/SSB: the preferred modes for weak signal work.

FM: Not suitable for weak signal work and not compatible with SSB or
CW. This category also includes digital modes such as packet, which
usually use FM mode on the VHF bands.

ATV: Requires a very large bandwidth but has a very low power density,
so it needs an exclusive interference-free band segment.

Calling Frequencies

On the VHF bands, the band plans include calling frequencies. These
frequencies are "meeting places" and should be used only to make
initial contact before moving to another frequency. If you "hog" the
calling frequency you will prevent others from making calls or hearing
more distant stations that may appear on the frequency.

PROPAGATION CONDITIONS

Probably due to the web site problem and the fact that we could not
contact our regular contributer, ZS6BZP, by telephone, Marten, ZS6ZY,
acquired the information which follows for us.

At present the sun spot number is 12 with an associated sun flux figure
of 71, which is evidence of very low sun activity. The geomagnetic
conditions will be quiet to unsettled with sporadic active periods
during the coming week.

Propagation graphs show that communication with Europe on 14 MHz may be
successful between 09:00 and 17:00 UTC and sporadically on 21 MHz
between 09:00 and 16:00 UTC.

To the Far East 7 MHz contacts may be successful between 02:00 and
18:00 UTC and on 21 MHz between 17:00 and 23:00 UTC. It is interesting
that no data is shown for 14 MHz.
