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. Details: Event Name: Apollo 11 Moon Landing 25th Anniversary Date/Time Period: 1700Z, July 19 through 0500Z, July 22 (1300 EDT, July 19 through 0100, July 22) Modes: CW, SSB, FM, Packet, Pactor, Amtor, RTTY, SSTV, ATV, Satellites. Frequencies: HF CW/SSB: Check 11 (as in Apollo 11) kHz up from the bottom of the General Class portion of the amateur radio bands (except 10m SSB: 28.411+ MHz). Other Modes: Check modes/frequencies as indicated by the individual stations below. QSL Information: A certificate is being designed to commemorate this special event activity, which will be individualized for each special event station. Domestic Stations: Send a 9" x 12" self-addressed, stamped envelope to the callbook address (CBA) of the station worked or to the address specified by the station worked. Attach $0.52 postage to cover return mailing. DX Stations: Send a 9" x 12" self-addressed envelope to the appropriate address, with sufficient IRC's or U.S. Postage for return mailing of up to 1.5 oz (42.52 grams). Europe = $1.40US postage (3 IRC); Mexico = $0.63US postage (2 IRC); Canada = $0.55US (2 IRC).

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 ------------------------------ Date: Fri, 8 Jul 1994 17:31:06 GMT From: ihnp4.ucsd.edu!usc!elroy.jpl.nasa.gov!lll-winken.llnl.gov!fnnews.fnal.gov!gw1!nntpa!not-for-mail@network.ucsd.edu Subject: Looking for STSORBIT (*not* Plus) - found!

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 ------------------------------ Date: Fri, 8 Jul 1994 18:07:20 GMT From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!spool.mu.edu!howland.reston.ans.net!torn!nott!cunews!freenet.carleton.ca!FreeNet.Carleton.CA!ao859@network.ucsd.edu Subject: oscar rigs, etc. 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.
