AMSAT-NA Board of Directors Ballot Deadline Approaching

A final reminder that Board of Directors ballots must be returned to the AMSAT-
NA office by 15 SEP 2014 in order to be counted. Your returned ballot should be
sent promptly, and those from outside North American preferably by air mail or
other expedited means.

Normally there would be 3 full Board seats open this year, plus 2 alternates.
However, with the passing of Tony Monteiro, AA2TX (SK), there will be an
additional full Board seat open to fill the remainder of his term. This means
that the top three recipients of votes will have two-year terms, the
fourth most vote recipient serving as full member for one year. The fifth and
sixth highest vote recipients will serve as first and second Alternate,
respectively. You may vote for up to 4 individuals.

Election of board members is both an obligation as well as an opportunity by our
membership to help shape the future direction of AMSAT-NA. Please take the time
to review the candidate statements that accompany the ballot and determine who
you wish to see on the Board.

W1AW/7 Satellite Operations

Following the schedule for W1AW/x portable activity during 2014, next
week will start the second of the two weeks W1AW/7 will air from
Arizona. The first W1AW/7 Arizona satellite activity in March was
successful (thanks, John K8YSE, for making good use of the K8YSE/7
station in Arizona that week). The next operation will be starting at 0000 UTC
Wednesday, 27 August (2000 EDT/1700 PDT on
Tuesday, 26 August).

Patrick, WD9EWK/VA7EWK, will be operating as W1AW/7 on weeknights, and plan on
more activity
during the Labor Day weekend (30 August-1 September) that falls within
this one-week period. He is working on having additional operators for
the weekday passes, when he won't be able to get on the radio. As
with any of the W1AW/x activities, ARRL will handle the QSLing. ARRL will
upload all W1AW/7 logs to Logbook of the World, in addition to the
paper QSL cards that will be available later.

If you also work other bands and want to work W1AW/7 from Arizona
next week, the W1AW/7 Arizona activity coordinator, Ned Stearns AA7A,
has a schedule showing when the other stations operating as W1AW/7
will be on - and on what band/mode combinations. This schedule is still
being assembled, so more slots will be filled in as we get closer to next

You can see that schedule at:

Satellite operating times will not appear on Ned's schedule, as Patrick is
coordinating that part of the W1AW/7 effort. Patrick will use the AMSAT-BB
list and his Twitter @WD9EWK feed (http://twitter.com/WD9EWK ) to send
out updates for the W1AW/7 satellite activity.

Good luck, and 73!

Fox-1 Update - Slow Speed Telemetry

The Fox-1 series of satellites feature a slow speed telemetry, with 200 bps data
being sent along with the transponder audio or voice ID activity. This allows
telemetry to be sent continuously during normal transponder operation while QSOs
are taking place.

The slow speed data is contained in the audio spectrum below 300 Hz. Using DSP
techniques, high pass filtering is applied to the uplink signal and voice IDs,
low pass filtering is applied to the telemetry audio which is generated by the
IHU, and the combined audio is sent on the downlink as the voice and data.
Forward error correction added to the downlink stream provides data recovery for
up to 1/4 second signal fades.
Fox-1A slow speed telemetry

Screen print of actual Fox-1A downlink slow speed telemetry received over the
air on a FUNcube Dongle Pro+ with SDR# and a decoded/displayed with command line
version of the AMSAT ground telemetry decoding software used in our testing

The slow speed data on Fox-1A contains four different payload types: Current
telemetry readings, High telemetry readings, Low telemetry readings, and
Vanderbilt University radiation experiment telemetry. The payloads are
transmitted in a scheduled rotation that delivers one payload or frame about
every 5 seconds. Current telemetry is thus received every 15 seconds,
experiment telemetry is received about twice every 15 seconds, and high or low
telemetry received once every minute (alternating minutes between high and low).

The telemetry contains many satellite health and operation values, including
readings such as solar panel output, battery voltages, temperatures from various
areas of the satellite, IHU performance, and the Penn State University MEMS gyro
experiment data.

AMSAT will be providing free GUI software for decoding and displaying both slow
and high speed telemetry from the Fox-1 series of satellites, as we get closer
to launch. The software will be similar to the user software that was provided
for ARISSat-1.

AMSAT has an immediate need to raise funds to cover both the launch contract and
additional materials for construction and testing for Fox-1C. We have set a
fundraising goal of $125,000 to cover these expenses over the next 12 months,
and allow us to continue to keep amateur radio in space.

Donations may be made through the AMSAT webpage at www.amsat.org, by calling
(888) 322-6728 or by mail to the AMSAT office at 10605 Concord Street,
Kensington, MD 20895, USA. Please consider a recurring, club, or corporate
donation to maximize our chance of success with this mission. You may also
dontate via PayPal. Donations will be marked specifically for Fox-1C. Note
that PayPal usually allows you to donate with a credit card, even if you do not
have a PayPal account. However, PayPal requirements differ depending on your
country. We have not control over this issue.

You may also contribute through a special “crowd sourcing” campaign on
fundrazr.com at the following link.

Peruvian Cubesat Chasqui-1 Deployed From ISS

The Russian Space Agency, Roscosmos announced that a nano satellite with the
designation, NS-1 was hand-launched during a space walk that began at 14:00 UTC
Monday, August 18, 2014.

The satellite is also referred to as the Peruvian Cubesat Chasqui-1 and weighs
1.5 kg. The satellitea^EUR^(TM)s main mission is to serve as a platform for testing
micro-electronics and optical devices used in cubesat applications.

Its secondary mission is to operate as an amateur radio satellite. Ita^EUR^(TM)s
downlink is 437.025 MHz. The craft will send information in CW mode. It also
transmits images stored in memory, photos taken by two on board cameras and will
send telemetry. Data transmissions will use either 1200 bps AFSK AX.25 or 9600
bps GMSK modes.

A direct contact with students at Dorothy Grant Elementary School, Fontana, CA,
USA was successful Wed 2014-08-27 18:31:28 UTC 83 deg. Astronaut Alexander
Gerst, KF5ONO was able to answer 7 questions for students during the
communication window.

Dorothy Grant Elementary School proudly earned the California Department of
Educationa^EUR^(TM)s 2013 Title I Academic Achievement Award and is a California
Distinguished School. This prestigious honor is a reflection of the schoola^EUR^(TM)s
system of support for all students at all learning levels. Innovative
intervention strategies and differentiated instruction greatly impacted school-
wide student performance to meet state and federal standards of excellence.

On October 27, 2012, the Dorothy Grant Elementary Amateur Radio Club was
established. Each year nearly 50 students in the 4th and 5th grades learn about
amateur radio and participate in activities and programs that teach them about
electronics and radio communication techniques. Amateur radio has enhanced
reading, writing, mathematics, geography, and communication skills for all
students. The club recently installed a 50 ft. Rohn tower and beam antenna in
hopes of making more international contacts on 10, 15, and 20 meters. The use of
technology is strongly emphasized throughout the curriculum and used as a tool
to enhance class lessons.


A telebridge contact via IK1SLD providing an interview for students at SPACE
KAMP Sterrenlab, Noordwijk, The Netherlands with astronaut Alexander Gerst,
KF5ONO was successful Tue 2014-08-26 11:36:32 UTC 65 deg. Gerst answered 18
questions for students.

The Amicale Space Camp includes 25 children aged 8-13 years old of different
European nationalities. It includes children of the European Patent Office staff
and takes place in Noordwijk (Stay Okay hostel) from the 25th to the 29th of
August 2014. All camp activities are designed to entertain children, stimulate
their creative and manual skills, and teach them about science and space. The
contact with the International Space Station will be a key activity in the
program as it gives the children the opportunity to talk with an astronaut and
understand that space is an international endeavor.


A direct contact with students at Winfree Bryant Middle School, Lebanon, TN, USA
was successful Tue 2014-08-26 16:12:47 UTC 24 deg. Astronaut Gregory
Wiseman, KF5LKT answered 16 questions for students.
