SUNSAT SUCCESFULLY LAUNCHED, SMILES ON THE FACES OF THE STELLENBOSCH
TEAM AFTER 24 HOURS OF PANIC

SA AMSAT TO HOLD RELAUNCH AGM AT  AMATEUR RADIO AFRICA 99 ON APRIL 24.

SARL YL/OM CONTEST TO BE HELD ON MARCH 11.


You are tuned  to ZS6SRL, the news in detail next


South Africa’s first satellite, SUNSAT, was successfully launched after
many attempts marred by inclement weather conditions. In a flawless
launch on Tuesday  SUNSAT was placed in its 620 x 850 km orbit 1 hour
and 40 minutes after the rocket roared towards the heavens.  There were
anxious moments at the University of Stellenbosch ground control station
when the satellite failed to respond to command signals. Careful
scrutiny of the equipment configuration and some minor adjustment solved
the problem.

The next day SUNSAT responded to ground commands with clear telemetry
from the magnetometer. Needless to say that the Stellenbosch guys were
all smiles.

Cliff  K7RRof the Vandenberg Airforce Base Amateur Radio club reports
that the success of Sunsat continues. “There were four continuous
downlink and  up and downlink orbits, two in the middle of night and
three on Friday afternoon.  We obtained telemetry on the very first
uplink command when the satellite was in the East.  On the overhead pass
the controllers commanded the voice digitalker to respond: I am alive! “

On Friday evening the Stellenbosch  ground control station  successfully
deployed the boom which will stabilise the satellite. Commanding is
continuing . Radio Amateur can expects some interesting audio from the
digitalker. Stay tuned for information about this event next weekend.

Garth Milne ZR1AFH expressed his appreciation to the members of the
Vandenberg Airforce base Radio Club for their hospitality and support
during the protracted launch period.

SARL APPOINT A TECHNOLOGY TASK GROUP

The SARL Council has adopted a proposal  to promote new technology in
Amateur Radio and to establish  an Amateur Radio Technology Task Force
to develop a strategy plan for exploring new technologies and assessing
their applicability and possible incorporation into Amateur Radio.

The image of Amateur Radio as a collective group of people doing
research and developing new technologies or applications for new
technologies is  fast fading.  Within the group there appears to be
little new technological activity and the few that are engaged in this
field do not publish and share their expertise to involve more radio
amateurs. There is work going on in EME, VHF/Microwave, propagation,
digital communications etc. TAPR in the USA is leading the field with
several new developments. The SARL, as the national society of Radio
Amateurs has an obligation to its members and the Amateur Radio as a
whole to take the lead.
Tony Reumerman ZS6AOG has been appointed to lead the group. Volunteers
wishing to join the group are invited to contact Tony at 011  792 6583
or by Email: tony@ecssa.co.za

An INTECNET is planned for Sunday March 28 March from 20:00 to 21:30.
Clubs wishing to link into the net are requested to send details to
sarlnews@intekom.co.za or by fax to 031 765-6456.

MORE HAMRADIO ON THE SILVER SCREEN?

A research company reviewing a script for a new movie involving ham
radio called Frequency contacted the ARRL. The film, starring Dennis
Quaid, is about a young boy from New York who loses his father in a fire
in 1969. Years later, the son is "reunited" with his late father via ham
radio. While the story line may be a bit far-fetched for some, the movie
may give Amateur Radio some additional positive exposure on the big
screen. Bart Jahnke, W9JJ, helped Jennifer Hagy, N1TDY, to research a
call sign--one that's not likely to be issued--that may be used in the
movie. No more details on the movie or when it will be filmed are
available at this time.

SEND A MESSAGE TO THE CAPE AGULHAS LIGHT HOUSE


"The Cape Agulhas Lighthouse (will be 150 years old on 1 March 1999. A
small group of people who live near the lighthouse and have a deep
affection for her,  have created a dedication page for the lighthouse
for this momentous occasion:
http://www.cape-explorer.com

The group are trying to raise world-wide, 1 million e-mail greetings for
this grand old lady of the seas.  Those who send a greeting to
http://www.cape-explorer.com will have their name and greeting cut to CD
ROM and these CD ROMS will be sealed into her datestone permanently on 1
March 1999, thus, hi-tech and history converge, and allow us to honour
her in a manner that is fitting to the wonderful contributions to human
safety she has made
over the past 150 years.

This is a private initiative, is non-profit orientated and asks for
nothing other than the opportunity to repay a kindness and dedication to
service in the form of 1 million e-mail greetings.

by next weekend.  Solar activity is expected to be Low this weekend - No
major solar flares or other major activity is expected.

MUF's should be at predicted values or even slightly higher.  Radio
Amateurs should look for good DX on 10 metres in the  late afternoon and
early evening. Around 21:00SAST  very good   propagation on 40m with DX
should occur on east/west paths.

Field should start "coming to life" again.
