Apollo 11 25th Anniversary Amateur Radio Special Event Station Activity
At 1627 EDT, Sunday afternoon, July 20, 1969, astronaut Neil A. Armstrong
spoke the words "Houston, Tranquility Base here. The Eagle has landed."
At 2256 EDT, later the same day, Armstrong stepped down from the ladder
of the Lunar Module onto the Moon's surface and spoke the words, "That's
one small step for a man, one giant leap for mankind."
To commemorate that historic event twenty-five years ago next week, amateur
radio clubs and groups at NASA Headquarters and the various NASA field
centers will be on the air as "Special Event Stations", contacting amateur
radio operators around the world.
Amateur Radio clubs or groups from twelve NASA locations are currently
preparing for the 60-hour special event operating period from their
respective facilities. Ham groups from other NASA locations may also be
on-line to participate by the time the special event period arrives. This
is the first time so many NASA stations will be represented on the air at
one time. Contacts with these stations during the special event period
will be confirmed on request with a certificate to commemorate man's first
steps on the Moon and the special event activity.

From: news-mail-gateway@ucsd.edu
Subject: KLV vs. M2 antennas
To: ham-space@ucsd.edu
Has anyone ever compared M2 antennas to the small KLM satellite antennas?
They both use 14 elements on VHF.
KLM is 22 elements on UHF, and M2 is 30 elements on UHF.
I would be particularly interested in any comments about the following:
1. gain
2. overall mechanical construction
3. performance in rain, snow, and ice
4. ease of polarity switching
Also, is a wood closet rod acceptable as a crossboom?
If so, is polyurethane an acceptable sealant?
Please respond to the newsgroup (others are interested in M2 vs. KLM comments)
or directly to wayne@csg.mot.com
Thanks, and 73,
Wayne Estes WD5FFH, Mundelein, IL

I was able to ftp it from spacelink.msfc.nasa.gov
The filename is STS9201.ZIP
Note: the ftp server there isn't setup completely, so you won't be able
to see any files in the directory!
Thanks to Don Ryan, N2QFE for the info.

Subject: Multiple questions on satellite stuff
To: ham-space@ucsd.edu
Any one have two-line elements for the moon. Mine seem to be old (not a joke).
Actually, the keps I have put the moon in a slightly different position
than a GPS receiver said it would be.
What is the latest version of InstanTrak? Also, how does it determine the
age of a satellite from the International ID? In effect, how is the ID
composed?
thanks

To: ham-space@ucsd.edu
To get started with satellite communications a 25w or 50w 2m all mode
with a 3 el or 4el yagi mounted horizontal is ok for uplink to
2 satellites , RS10 and FO20. for the downlink you require
a 10m rig , i suggest an Radioshack HTX100 , they can be had for $100
this will do for the RS10 downlink using crossed horiz dipoles
and maybe a preamp for HF. Kit from Hamtronics NY $29.00.
then for FO20 downlink build an 8 el Quagi , using pine and 1/8 aluminium
rod for elements and #14 copper house wire for drive and reflector
see ARRL antenna handbook for dimensions (one eveing project) just
follow instructions. then to convert from UHF FO20 downlink to
HF 10m Hamtronics 435.5-437.5 rx converter kit $49.00. and you can
reuse your 10m preamp for this as well.
You will have to do a little work to get to FO20 however RS10 is
easy to begin sat operation.
