AO-7 eclipses return, satellite now primarily in Mode U/v

From AMSAT-bb (http://amsat.org/pipermail/amsat-bb/2016-November/061297.html):

The AMSAT satellite status page at http://www.amsat.org/status/ indicates
that as of the morning of 11/25/2016, AO-7 is once again entering eclipse
each orbit. This means that the 24 Hour mode change timer is interrupted
each orbit, and the satellite will be found primarily in Mode U/v (aka Mode
B).

As the satellite is powered solely by the now 42 year-old solar panels, it
is very sensitive to strong uplink signals, particularly CW. Users should
closely monitor their downlink for excessive chirp, warbling or “FM’ing” and
reduce power as necessary. More information including frequencies can be
found at http://ww2.amsat.org/?page_id=1031

LUSEX-OSCAR 87 (LO-87)

The Argentinian earth observation satellite ÑuSat-1 carries a linear transponder built by AMSAT Argentina. The satellite was launched on a CZ-4B rocket from Taiyuan Satellite Launch Center in China on May 30, 2016 into a 500 km sun-synchronous orbit with an inclination of 97.5 degrees and a Local Time of the Descending Node (LTDN) of 10:30.

The AMSAT Argentina U/v inverting transponder, named LUSEX, has an uplink of 435.935 MHz to 435.965 MHz and a downlink of 145.935 MHz to 145.965 MHz. Total power output is 250 mW. There is also a CW beacon at 145.900 MHz with a power output of 70 mW.

The transponder and beacon are currently active over Latin America and Europe.

For more information, see the AMSAT Argentina LUSEX page at http://lusex.org.ar/

Fox-1Cliff and -1D Matching Contributions Offer

Merry Christmas and Happy Holidays to AMSAT members and satellite enthusiasts everywhere!

In this season of giving, we’ve had a generous offer for matching funds up to $1,000 for those that contribute to the Fox-1Cliff and -1D crowdsourcing campaign at https://fundrazr.com/campaigns/6pz92/ab/561Zd between now and December 31st. Make your donation twice as valuable by taking advantage of this opportunity and contributing before the end of the year, and help AMSAT fund the launch of the next two satellites in the Fox-1 series.

Slated for launch in 2016 on the inaugural Spaceflight SHERPA mission aboard a SpaceX Falcon 9, Fox-1Cliff and -1D carry university experiments from Pennsylvania State-Erie, Vanderbilt, University of Iowa, cameras provided by Virginia Tech, as well as amateur radio voice repeaters capable of U/V or L/V operation.

Donations of $100 or more are eligible for a special AMSAT Fox challenge coin, and $1,000 or more qualifies for a plaque with an actual solar panel cover from Fox-1Cliff or -1D. (We’ve nearly exhausted our coin supply and are waiting on resupply from the mint. Plaques will be distributed sometime after spacecraft integration. Please be patient for delivery of either premium.)

AMSAT is a 501-(c)-(3) not-for-profit educational and scientific organization of amateur radio operators whose purpose is to design, construct, launch, and operate satellites in space and to provide the support needed to encourage amateurs to utilize these resources. Please consider a tax-deductible contribution to AMSAT to help underwrite the development and launch expenses of our Fox satellite program.

Donors wishing to provide additional matching funds please contact Drew Glasbrenner, KO4MA at ko4ma@amsat.org.

4U1UN as 4U70UN on satellite October 24-25

4u1unWord has been received, that, in celebration of the UN’s 70th
anniversary, 4U1UN will be activated as 4U70UN on Saturday 24 and Sunday
25 October. The operation by the UN ARC will be from the ground-level
garden area within the UNHQ complex in New York City and will be limited
to daylight hours. Satellite operation is included in the plans, but
time and equipment limitations will exist. Blockage from high rise
buildings toward the West is expected. Best passes will be to the East
of FN30as and North/South overhead. Possible satellites in view may be
AO-73, FO-29, AO-85, AO-7, SO-50, XW-2E and XW-2F. Note that 4U1UN is a
separate DXCC entity. See QRZ.COM for QSL info.
