Dr. Perry Klein, W3PK reports that The Smithsonian National Museum of
American History has installed the Microsat Mechanical Test Model last
week so that it will be on display in time for AMSAT's 35th Anniversary
meetings.  They suspended it from the ceiling outside the NN3SI
Smithsonian Amateur Radio Club station, located at "The Information Age"
exhibit on the first floor, West end of the American History Museum.
        
It's been a number of years since an OSCAR satellite has been on
continuous display at the Smithsonian.  OSCAR 1 was in the Hall of
Satellites at the National Air and Space Museum for several years, but
has since been in storage at the Smithsonian's Garber Facility in
Suitland, Maryland.  OSCAR 1 and PC-Sat are currently being readied for
display at the Air and Space Museum's Udvar-Hazy Center near Dulles
Airport when the Center's space exhibit hangar opens, expected soon.

PSK31 Experimenters Wednesday Info from Mike, KE4AZN.

Wednesday night I finally had a PSK31 signal to tune in and was able to
get Echo configured for better audio in PSK31 mode.  The improvement was
very noticeable to the ear, and the one and only report I received from
that time frame indicated 100% copy on 4 different signals.
Unfortunately, that setup only ran one orbit before Echo was switched
into another mode.  I think we have something that can be worked with
now.  We will try another PSK31 session in the future and hopefully see
good results as we learn to operate this mode on a satellite.

For the record.  We are using the SQRX wide band receiver to receive 10
meter signals on Echo.  And the antenna is in fact the VHF whip on the
+Z axis of the satellite.  There are no changes I can make to the
receiver from the ground.  I do have control of a few parameters on the
transmitter side, in the flight computer (IFC).  If you look at the Echo
Block Diagram, which has been published in many different places, you
will notice three paths that the signal can take in the IFC to the
transmitter.  Those are Straight, Resistor, and CTCSS (which includes a
resistor).  For FM repeater mode we run either the Resistor or CTCSS
path.  This provides the best audio in that mode.  What I found was
using the Straight path, which eliminates the resistor, improved the
output signal of the satellite when receiving on 10 meters USB.  Also,
the Amplitude of the Transmitters signal can be changed from the ground,
and that parameter was modified with the straight path to get the best
output.  I did not have enough time during that one pass to be sure I
found the best amplitude setting, but it was close.

Next time we run this mode I feel like you will see a nice improvement
in Echo's output.

October 2004 Schedule for AO-51 AMSAT-Echo

The October Schedule for AO-51 (Echo) is shown below.  At the current
time there are no plans to load new software up to Echo.  If for some
unplanned reason there is a need to work with Echo and deviate from the
plan a note to the Echo page on AMSAT.ORG will be posted.

All dates are UTC.  The mode change occurs normally between 0100 and
0400 UTC on the date shown.  The mode will be active from the date shown
until the next Mode Change date listed.  Mode Configurations are listed
below the schedule.

Please do not access the BBS system on Echo when the schedule calls for
it to be off.  The only time TXA will be turned on during a scheduled
off period will be when the satellite is over a command station, and the
command station needs to work with the satellite.  Accessing the BBS at
this time will only slow down and/or delay the command stations efforts.

Also, check the broadcast message on the digital downlink.  If it says
the BBS is CLOSED then do not transmit on the digital uplink.

1. Investigator Centre Contact Successful

The Investigator Science and Technology Centre in Adelaide, Australia, a
non-profit center that provides educational programs to schools,
welcomed Kilburn Primary School to participate in a contact with the
ISS. Kilburn has an enrollment of approximately 130 students. About 20%
of the students are Aboriginal and 25% are from non-English speaking
backgrounds. The school focuses on Literacy, Numeracy, ICT and a
Supportive School Environment, and many of the students have significant
learning needs. On September 23, Kilburn°«s fifth and sixth graders had
the opportunity to speak with Mike Fincke, KE5AIT, via the telebridge
station, WH6PN, in Hawaii. Students posed thirteen questions to Fincke,
as an audience of sixty people looked on.  The event was covered by the
media, which included ABC radio (Australia°«s national radio system),
University Radio, a local FM station, and a newspaper. An article will
also be published in the State Educational Journal for teachers.

Mike Fincke used the Kenwood radio to speak to the children of Kilburn.
This was the first time the Phase 2 hardware was used for school
operations, and because this contact was successful, the ARISS team
plans to use the Kenwood radio for the remaining contacts of Expedition
9.  After the contact, the radio was placed in repeater mode, and will
remain in this mode until the next school contact scheduled for
September 30.  


2. Upcoming School Contacts

The Primary School of Montaud in Montaud, France has been scheduled for
a contact with Mike Fincke.  It is planned for September 30 at 1158 UTC.

Two Poland high schools and a university will share an ARISS contact.
All three schools are located in the Pomorskie Province. Gdynia Maritime
University and Gdynskie Liceum Autorskie STO (High School) both located
in Gdynia and Zespol Szkol Ogolnoksztalcacych Nr 5 (High School) in
Gdansk are scheduled to speak to the ISS on Wednesday, October 6 at
11:55 UTC.


2. Marina Air Fair Contact

Mike has expressed interest in a contact with the Marina Air Fair in
Marina, California.  This event will take place on Saturday, October 16.


3. ARRL Article on the Aoyama School and ESA ESOC Contacts

The ARRL ran a web story on two recent ARISS contacts.  Links to the
audio of both the Aoyama Gakuin Elementary  School and °»Long Night of
the Stars°… ESA ESOC contacts may be found on their website. See:
°»Astronaut Thrills Audiences in Japan, Germany via Amateur Radio,°… at
http://www.arrl.org/news/stories/2004/09/23/2/?nc=1


4. ESA ESOC °»Long Night of the Stars°…   

On September 18, an open house known as  °»Long Night of the Stars,°… was
held at the control center of ESA ESOC in Darmstadt, Germany. The
highlight of the evening was the contact with Mike Fincke, KE5AIT, on
board the International Space Station. There was wide media coverage
including newspapers, magazines, news agencies, the Hessen TV station,
and several radio stations.  Over 120,000 people listened in on the
contact.

ESA ran an article on the event entitled, °»Sell-out crowd wowed by
ESOC's Long Night of the Stars,°… and can be found at:
http://www.esa.int/SPECIALS/ESOC/SEMIP61XDYD_0.html

The ARISS-Europe website also posted a story on the gala with a link to
the audio of the contact.  See:  °»ASTRONAUT MIKE FINCKE PARTICIPATES TO
THE °»LONG NIGHT OF THE STARS,°… at http://www.ariss-eu.org/2004_09_20.htm


5. ARISS International Meeting 

The monthly ARISS International Teleconference was held on Tuesday,
September 21. The main item discussed was the agenda for the face to
face meeting scheduled for next month. The AMSAT/ARISS meetings will be
held on October 8  13 in Arlington, VA. To view the agenda, see:
http://www.amsat.org/amsat-new/symposium/agenda2004.php


6. ARRL Posts ARISS News on LM_Net

The LM_NET list is a school Library Media listserv for school library
media specialists and people involved in the school library media
field.  The ARRL PR Committee now posts news items to this listserv
whenever an ARISS radio contact is scheduled in the USA during school
hours.
