MONDAY DECEMBER 18, 1989
SpaceNews originates at KD2BD in Wall Township, NJ, and is distributed weekly
around the world. It is available for UNLIMITED distribution.
* STS-32 NEWS *
---------------
US Space Shuttle "Columbia" is currently located at launch pad 39-A at KSC in
preparation for mission STS-32 later this week. If a launch delay occurs, then
the mission will be postponed until January 1990. Columbia will be using the
newly refurbished launch pad 39-A at the Kennedy Space Center. Pad 39-A was
last used in January 1986.
During mission STS-32, the crew will deploy the SYNCOM IV-05 communications
satellite, and retrieving the Long Duration Exposure Facility (LDEF).
This will be a unique mission since it requires the support for both a payload
to be deployed and the return of LDEF. LDEF's processing and de-integration
work at KSC will involve operations in the Orbiter Processing Facility, the
Operations and Checkout (O & C) Building, and the Spacecraft Assembly and
Encapulation Facility (SAEF) number two.
* OSCAR-10 OPERATIONS *
-----------------------
AMSAT-OSCAR-10 is currently available for Mode B transponder operations on
a continuous basis. Please remember to use the minimum uplink power required
to facilitate communications.
* OSCAR-13 OPERATIONS *
-----------------------
Here is the latest operating schedule for AMSAT-OSCAR-13:
MODE B MA 000 to MA 110
MODE JL MA 110 to MA 145
OFF MA 145 to MA 150
S BEACON MA 146 to MA 147
MODE S MA 147 to MA 160
MODE B MA 150 to MA 225
OMNI ANT MA 225 to MA 035
* SpaceNews NEWS *
------------------
SpaceNews has been in existance for over two years, and some of you might be
interested in how these bulletins are created each week:
SpaceNews bulletins are written and distributed using Amateur Packet Radio
(AX.25) technology. Issues are edited using a Commodore 64 computer. Much of
the news contained in these bulletins is obtained from amateur satellite
OSCAR-11. Orbital predictions of the spacecraft, as well as data capture and
decoding functions are also performed using a Commodore 64 running software
specifically designed for use with the OSCAR-11 spacecraft (written by KD2BD).
Other important news souces include NASA, ANS (The AMSAT News Service), and
USENET. SpaceNews has been available on USENET for just over one year now.
It has been available on Amateur Packet Radio (AMPR) for two years, although
the distribution paths sometime change. It is available for free distribution
and can be found on electronic news systems all over the world.
I always appreciate hearing from the readers of SpaceNews, and try to respond
to all comments and suggestions received. It takes a lot of time and work to
prepare SpaceNews each week (which is why it sometimes doesn't get out!), and
it is the interest of SpaceNews readers that make the effort all worthwhile.
Thanks and Happy Holidays Everyone!!

The Handbook is also not a monthly publication that every ARRL member
receives. Neither is QEX. Neither is the proceedings from the various
microwave conferences. The Handbook, while a good reference, does not
serve the purpose of letting the general amateur population know what is
going on in the microwave spectrum. It is not possible to include
timely postings like recent DX records, events like contests, etc. in
the Handbook.
In addition, several prominent microwave operators have commented that
with all the 6m activity, there just won't be enough space to do any
justice to microwave material in "The World above 50 MHz". This seems
to be true so far. Perhaps the name of this column should be changed to
"The World between 50 MHz and 450 MHz." [I think that this column is
great, but it still doesn't do what "The New Frontier" used to do.]

Subject: CDE Rotators
CDE rotators (Ham-M, Tailtwister, etc.) are built by
Telex-HyGain at their Lincoln, Nebraska factory. I was there
last year with the Central States VHF Conference. Nice, big
factory, wonderful people. If you need repair parts, they
have them, plus a full-time person to handle inquiries.

True and another reason why a small diameter helical antenna is worse than
a simple vertical of comparable height and wire size.

A word of gentle warning to learning-to-be-advanced rn users:
Be careful when you try the above trick, as it is real easy to
end up killing things you wanted to see, like articles with
the word 'swift' or 'swan' in the header... Its a good idea to
wildcard with as many characters as possible rather than as few
as possible (IMHO!).
(I don't know if I'm an 'advanced rn user', but in any case thought
I'd pipe up and post)

There used to be a ham radio fraternity called "Synton". It was 'mortally
wounded' by WW2 but a handful of chapters lingered feebly until the early
fifties. So far as I know, the only surviving evidence is the former University
of Illinois (Urbana-Champaign) chapter, which to this day is called the Synton
Radio Club. That last I heard, they have no written records of their history.
Perhaps past issues of QST would help. Surely there were references to college
ARC's.
