RADIO AMATEUR EXAMINATION CLASSES IN WESTERN CAPE

Under the auspices of the Cape Town Amateur Radio Centre, a course of
lectures for the November RAE will be given as from the middle of September
2000.  The course is open to all candidates irrespective of whether they
belong to the CTARC or any other club or no club at all.

As in the past, the classes will be held weekly at the Signals Unit near
Acacia Park in Goodwood, as this is the most central venue for most of the
students who have already indicated their intention of participating.

The course leader is Pierre Tromp, ZR1PDT, who ran the last series of
classes which resulted in a 100% class pass rate in the May examination.
He will be assisted by guest lecturers from the Cape Town Amateur Radio
Centre and the Boland Amateur Radio Club.

Interested parties are requested to contact ZR1PDT on 083-229-7795 for full
details.  They must also remember that enrollment entries must reach the
SARL HQ on or before 9 October 2000.

accordance with the single norm of what was the best for the club;

Please listen for this beacon from 22:00 till past 24:00 SAST.  In case of
any signals heard, please phone ZS2FM on his cell phone No 082 654 0623.

NAVAJO CODE

Morse is not the only code.

Devotees of the TV programme 'The X-Files' will find the following item
especially interesting, as will anyone interested in codes of various
types.

A native American who helped train the 'Navajo [pronounced 'Nav-a-ho'] Code
Talkers' during World War Two, has died.  Dooley Shorty passed away in
Albuquerque [pronounced 'Al-ber-ker-key'], New Mexico on Sunday the 11th of
June on his 89th birthday.  Dooley Shorty was not a radio amateur, but
during World War Two he was assigned to train fellow Navajo in the
deeply-secret code based on the Navajo native tongue.  The Code Talkers
then transmitted military messages in the Navajo language.  The Japanese
forces were never able to decipher them, giving the United States a
tactical advantage as the war progressed.

For those of you who may not be aware, Navajo Code Talkers had the ability
to encode a message, pass it to other Code Talkers, and then decode it
exactly into its original form.  Dooley Shorty was one of the best of these
talkers, and his expertise with his tribe's code was legendary DX News

SHORT CIRCUIT DELAYS SAQ TRANSMISSION

The giant Swedish 17.2kHz station SAQ was on the air last weekend, but was
unable to fulfil all of its original schedule.  From SM6LKM, who was at
SAQ, comes information on what actually happened.

Around 08:00 UTC, the monster 80-tonne alternator was brought up to speed,
but the fine speed control did not work.  It took several hours to locate
the fault.  Apparently there was a short-circuit in the feedback cable from
one of the alternator's stator windings to the speed-control servo system
in the big switchboard.  This servo system is very elaborate consisting,
amongst other things, of large motor-actuated liquid rheostats, which
SM6LKM describes as "tall bathtubs".  The faulty cable was eventually
bypassed with a pair of heavy wires across the floor, and SAQ was back on
the air again.  Keying of the transmitter is achieved by a magnetic
amplifier in the antenna circuit, where the keyed direct current is used to
saturate the core.  The nominal antenna current is about 600 amps into the
half-ohm feedpoint.

The scheduled transmissions at 08:30 and 08:45 UTC were abandoned, but
those at 12:30 and 12:45 UTC took place on time.  SM6LKM remarked that this
was the first failure of its kind for 75 years and said, wryly, "Nobody
knew that Murphy had invited himself!".

NEW AMATEUR SATELLITES TO BE LAUNCHED SOON

The first Amateur Radio Satellites from The Kingdom of Saudi Arabia are
presently being built by the Space Research Institute at the King Abdulaziz
City for Science and Technology in Riyadh.  Tentatively set for launch
August 25, 2000, these satellites will be capable of 9k6 digital store and
forward operation (Pacsat Broadcast Protocol compatible) as well as FM bent
pipe mode.  These satellites will use the following downlink frequencies.
Uplinks are in the VHF band and will be announced after commissioning:
SAUDISAT-1A 437.075 MHz; SAUDISAT-1B 436.775 MHz.

Amateur Radio is in its infancy in Saudi Arabia.  With these satellites,
designers hope that not only to add addtional communication satellites to
the space resources available to hams world wide, but also to increase the
awareness of the value of Amateur Radio in the Kingdom.

The first Malaysian Amateur Satellite, TIUNGSAT-1, is also to be launched
on the same vehicle DNEPR-1 as SAUDISAT-1A and SAUDISAT-1B on 25th August,
2000.  The launch wll occur from the Baikonur Cosmodrome, Khazakstan.

MIR NEWS

MirCorp's board of directors recently approved the permanently manned
operation of Mir beginning next year, marking a major milestone in the
company's plan to use this unique facility as the world's first true
commercial orbital space station.  The schedule of privately-financed
MirCorp flights begins with the launch of an unmanned resupply spacecraft
to Mir this fall, followed by two long-duration missions with cosmonauts in
2001.  It is unknown what this may mean for possible Amateur Radio
operation from the station.
