I couldn't help but notice that on this website
http://www.intelsat.com/resources/galaxy-15/faqs.asp about "zombiesat"
Galaxy 15, Intelsat figures that the lack of RF on thr transponder package
since their loss of control earlier this year, will actually make it take
longer to saturate it's momentum-wheel orientation stablizer system. This,
compared to the manufacturer's original estimate of achieving the saturation
condition beuing several months sooner having assumed normal full-load of RF
on the transponders.
My question is: How is this possible? Does the RF put acceleration-forces
on the transmitting antenna of the satellite similar to ion propulsion, or
does the uplink RF push on the receiving antenna? Is there some other
mechanism that can electronically alter the forces acting on the body of the
satellite based on the amount of RF power?

The strenuous repair work continues every day by a control station
to return in FO-29 transponder. JARL grand station says that the
command was not able to transmit even a pass of 18:46 UTC, 23 Oct,
so we will try again the transmission of the command with the pass
at 20:32 UTC, 23 Oct, and 07:45 UTC, 24 Oct.

23rd October 2010
N8MH de S.I.,
Mark,
Your recent message to Tom, K0TW, in respect to the
polarization of a helical antennae is not 100% correct.
You state, quote:
"How do you determine the resulting polarity of the [helical] antenna?
My response: when standing at the rear, does the cork-screw go
clockwise or counter-clockwise as it spirals away from you? That is
the visible difference, if building a helix. "
unquote:
Implicit in your answer (but not defined) is that a
Right-hand helix, when viewed from behind, spirals away from you in a
clockwise direction, the same as a standard screw thread.
That statement is true for the classical helical antenna,
/? la Kraus/.
However it is not true for the Quadrifilar Helix design,
which twists in the opposite direction to the classical helix.
Maybe people who do not know the difference, and unwittingly
build one with the twist in the wrong direction, get such very bad
performance when attempting to use it and complain bitterly that "the
Quad Helix does not work".

Thanks for the update, can other amateurs help or give information to the

Hi FO-29 users
JARL FO-29 command team announced that
FO-29 has turned off the transponder because it doesn't obtain enough
durations of sunshine now.
The FO-29 analog transmitter was not able to be turned on by the analog
transmitter ON commands which were sent from command team on 10/17
08:53(UTC) 10/23 18:42(UTC) 10/23 20:23(UTC) 10/24 07:40(UTC).
This announcement is written by Japanese and I did translate into English.
Hope she will return back to us.

1. School Contact in Australia
An Amateur Radio on the International Space Station (ARISS) contact for
Carine Primary School in Perth, Western Australia, Australia was held on
Tuesday, October 19 at 07:06 UTC via telebridge station WH6PN in Hawaii. The
school has incorporated the contact into its science curriculum. Guest
speakers present included representatives from an amateur radio club and the
science center, Scitech. Students from Kindergarten through grade 7 have
been involved in research and other activities in preparation for this
event, using IT and online resources, including the NASA Web site.
2. George Observatory Contact Successful
On Saturday, October 16, an Amateur Radio on the International Space Station
(ARISS) contact was held with scouts and astronomy club members attending
the Astronomy Day event at George Observatory in Needville, Texas. This was
a telebridge contact via station WH6PN in Hawaii. Approximately 150 people
attended and listened as Doug Wheelock, KF5BOC answered 12 questions about
life in space posed to him by the youth. As part of the event, scout troops
set up an amateur radio station near the observatory to conduct their
all-day Jamboree on the Air (JOTA) radio contacts and also worked on Radio
Merit Badges. The Brazos Valley Amateur Radio Club was on hand to assist
with JOTA activities and prepared for afternoon satellite contacts with an
Arrow hand-held antenna.
3. ARRL Article on ARISS Contacts
The American Radio Relay League (ARRL) ran a story on recent ARISS contacts
including those with Windsor Central School District, Utah Scouts and IRSEA,
as well Doug Wheelock's many general contacts. The article, written by Rick
Lindquist, WW3DE may be found at:

4. Amateur Radio Newsline Covers ARISS
On October 15, the Amateur Radio Newsline Report 1731 included two ARISS
related stories. "Ham Radio in Space: ARISSat-1 Enroute to Russia"
announces ARISSat's arrival at JSC and its planned shipment to Russia.
"Challenger Learning Center Inaugurates Ham Station" is about the station
set up at the CLC in Oregon, Ohio to get students interested in STEM
studies. Both stories may be found at:

FO-29 Operating Schedule Affected by Eclipses
Mineo Wakita, JE9PEL reported that JARL has been making necessary
adjustments to the FO-29 satellite operating schedule as the sat-
ellite enters a period of eclipses. The eclipses have reduced the
power budget requiring frequent analysis of available power aboard
the satellite.
FO-29 will be enable when the power budget allows. JARL requests
that satellite operators access FO-29 with as little power as nec-
essary to maintain communication.
Mineo has posted calculations of the FO-29 eclipses at:

Tom Clark, K3IO
Gould Smith, WA4SXM
Drew Glasbrenner, KO4MA
Lou McFadin, W5DID
Bill Ress, N6GHZ
Alan Biddle, WA4SCA
Tony Monteiro, AA2TX (Alternate)
Others:
Martha Saragovitz, Officer Manager
Keith Baker, KB1SF, Treasurer Elect
Due to the resignation of AMSAT Treasurer Gunther Meisse, W8GSM, President
Baines appointed Keith Baker, KB1SF/ VA3KSF to fill this position on an
interim basis, pending formal approval by the BoD. Keith spoke briefly,
stating that the transition had gone smoothly, and that he would be
continuing with past practices. He did bring up the status of the AMSAT
logo registration status. Martha reported that it had recently been
renewed. Barry moved, and Tom seconded, that Keith be approved. This was
passed unanimously.
The final version of the AMSAT Bulletin Board Acceptable Use Policy (AUP,
attached) was brought up for discussion. Bill expressed concern that the
dissemination was not adequately addressed, particularly with respect to the
Bulletin Board itself. Both Tom and Gould mentioned that the implementation
was separate from the AUP, and Lou emphasized that it should be in any case
readily accessible. Gould assured the BoD that it would be widely
disseminated, including the Bulletin Board itself. With this clarification,
it was moved by Barry and seconded by Alan and Tom that the AUP be accepted.
This was passed unanimously.
The current working revision of the AMSAT budget was not approved at the
annual BoD meeting due to some information not being available. This
information is now reflected in version #8, though Lou emphasized that the
ARISSat-1 budgeting was still incomplete. It was moved by Barry and
seconded by Drew that this version be approved. This was passed
unanimously.
It was moved by Barry and seconded by Drew that the 3 November 2009 BoD
telecon meeting be approved as circulated and published in the Journal.
This was passed unanimously.
There being no additional formal business, it was moved by Barry and
seconded by Alan that the meeting be adjourned. This was passed
unanimously.
The Official Board meeting closed at 2027 EST.
