I won't be on the linear birds until spring because I have to move my
entire station outside. It's cold out on my balcony!
I might be able to reach an FM satellite as my FT-817 is
well-insulated in the case I bought for it. All I need is a suitable
pass....

AMSAT SKN on OSCAR 2016 This Week
You are cordially invited to participate in Straight Key Night on OSCAR
2016,
sponsored by AMSAT for all radio amateurs throughout the world.
Operate CW through any amateur satellite from 0001 through 2400 UTC on 1
January
2016, using a manual, non-electronic key. Note that bugs are now
allowed, as
they are in similar ARRL and SKCC events.
There is no need to send in a log, but please nominate someone you
worked for
Best Fist. Your nominee need not have the best fist of those you heard,
just of
those you worked. Send your nomination to w2rs@xxxxx.xxx.. A list of those
nominated will be published in early February.
This year?s event is being held in memory of Ben Stevenson, W2BXA
(1914-2011).
Licensed since 1929, Ben was one of the world?s top DXers on both HF and
satellites. He led the DXCC Honor Roll for many years, and among his many
awards were Satellite DXCC No. 1 and post-war Worked All Zones No. 1.
Founding
president of the North Jersey DX Association, Ben shared his knowledge and
enthusiasm with one and all.

ARISS Celebrates 15 Years of School Contacts
15 years ago today, on December 21, 2000, students at Burbank School in
Burbank Illinois, U.S.A. lined us and readied themselves for a very
historic
event---the first school contact with the crew on the International Space
Station. ARISS mentor and radio operator Charlie Sufana, AJ9N and his team
of volunteers had aptly prepared the students, teachers and the public in
attendance for their historic contact. As AOS approached, Charlie began
calling NA1SS. Soon, Expedition 1 Commander Bill "Shep" Shepherd, KD5CDL
answered back and the students immediately began asking Shep their
questions. The rest is history.
Burbank school teacher, Rita Wright, who later became KC9CDL, continues to
be active in ARISS as a volunteer. Rita's 2004 AMSAT Symposium paper,
"Remember, We're Pioneers!" chronicles the Burbank school's journey to the
first ARISS contact and beyond. You are invited to download the paper at
https://www.dropbox.com/s/q8cmd0eu9y0imsz/REMEMBER--Burbank%20School.pdf?dl=0
With this historic event in mind, I would like to take this opportunity to
thank our volunteers from the ARISS operations team for their outstanding,
long term support to ARISS. These folks---our mentors, telebridge
operators
and operations leaders---are the foundation of ARISS. They have made
nearly 1000 ARISS contacts successful since Burbank, 15 years ago. Without
them, the goals of ARISS: inspiration, exploration, education and
experimentation, could not be achieved. Their guidance, mentoring and
presentations, before, during and after the contact were crucial in
achieving these goals. Thank you all!!
As the ARISS team prepares for 2016, with many schools in the queue,
prepared, ready and waiting for their upcoming contacts, ARISS is
gearing up
for another historic event---our 1000th school contact. Wow! 1000 ARISS
contacts!! To celebrate this historic event, I would ask those that
know of
an ARISS student that has graduated and is now in a science, technology,
engineering or mathematics (STEM) field to please have them share their
story with us. Please pass this along to others and have them send their
stories to me at ka3hdo at verizon.net or to our web master at ariss at
arrl.org.
We would like to compile these for our space agency customers and to share
the stories with the amateur radio community.

EO-79 Transponder Activation
On December 21, 2015 at 1038 UT, the EO-79 transponder was turned on for a
prolonged period.
The FUNcube transponder subsystem on QB50p1 (EO-79) had been provided by
AMSAT-
UK and AMSAT-NL and is a similar subsystem as on FUNcube-1, but without the
telemetry downlink circuitry.
The current software running on EO-79 does experience occasional
reboots. When
these reboots happen, the transponder is automatically turned off and
will have
to be turned back on by a command station. The FUNcube team has selected
a few
command stations to do so, but be advised the transponder may be off.
TLEs:
AMSAT keps name: EO-79
Celestrak keps Name: QB50P1
Celestrak file: cubesat.txt
NORAD # 40025
COSPAR designator 2014-033-R
Frequencies:
*Uplink:* 435.035-435.065 MHz LSB [See note below]
*Downlink:* 145.935-145.965 MHz USB
EO-79 has been set to only beacon the normal AX.25 beacon every 30 seconds
instead of 10 seconds. The beacon frequency is 145.815 MHz and consists
of AX.25
frames on BPSK. More details about the downlink can be found on the ISIS
Ham
Radio page at http://isispace.nl/HAM/qb50p.html
We kindly request you to share your experiences with the AMSAT Bulletin
Board so
everyone can benefit from operating tips and tricks, as well as being
up-to-date
on the status.
We would also welcome any observation related to the transponder
behaviour when
the AX.25 beacon comes on.
Just like FUNcube-1, the crystal oscillator circuits exhibit drift with
temperature. This means manual tuning will probably work best.
Mike Seguin N1JEZ notes: I found my downlink after setting my uplink
+12 kHz
from published spec
SatPC32 tracking software Doppler SQF information used by Peter VK4NBL:
EO-79,145950,435063,USB,LSB,REV,0,0
EO-79,145814.8,435070,CW,TELEMETRY,0,0
Lastly, the commanding team will not be available over Christmas, so the
current
activations are planned from today until Thursday 24th and from Monday 28th
until Thursday 31st

NASA Commercial Crew Program 2016 Children's Artwork Calendar
Some of the best works of art come from children who are only limited by
their imaginations, like the more than 150 young explorers from across the
country who submitted artwork depicting human spaceflight as they see it.
Sixteen masterpieces were chosen to be included in the NASA Commercial Crew
Program 2016 Children's Artwork Calendar, which is now available for
download in PDF format, at http://go.nasa.gov/1NVTww4. We offer a huge
"thank you!" to all the explorers, ranging in age from four to 12, who
submitted their work and hope that everyone will enjoy and use this
calendar
next year.

Hi!
I'm trying to put together some data to illustrate how many grids around
North America (including Mexico, Central America, and the Caribbean) that
have been active on the satellites in 2015. I asked for this information
on Twitter earlier today, and I'll make the same request here. If you have
operated from grids away from home, please send me the list of grids you
have worked from. Please include your home grid in the list. I would like
to make a map of grids that were available via satellite during 2015, and
possibly scribble an article for the AMSAT Journal as well.
Besides my own activity in 2015, I have lists from the following stations:
AA5PK
KA4H
KX9X
N8HM
NP4JV
W5PFG
I will generate a map based on all submissions I receive, and probably
some other maps based on the lists I receive from other stations. Even if
your list is nothing more than one other grid besides your home grid,
every submission is appreciated.
I am hoping to have this information by 15 January 2016, so I can then make
the maps and write that article about which grids have been on the air
during 2015 before getting too far into 2016.
Thanks in advance, and 73!

Nice overhead pass of AO-85 just now; decoded 52 packets with v1.03a of
FoxTelem in auto mode.
Question: Even though I heard a couple of stations attempting to work the
voice transponder, there seemed to be a constant carrier that looked like
data to me. Quite different from the sub-audio data that I have copied in
the past. On the SDR waterfall, it occupied maybe 12-15k KHz of the RF
spectrum, I believe. Has something changed since the last time I
downloaded AO-85 telemetry? Any idea what I was seeing? Were BOTH the
voice transponder and high-speed data on at the same time somehow?
IQ recording available if needed.
Thanks!

One comment about the "constant carrier". Remember that with FM, there
*is* a constant carrier as long as "PTT" is "pressed". And on AO-85 the
carrier stays on for 30 seconds after the last time it heard a 67-Hz tone.
And in addition, there is no squelch on the receiver (for the same reason
you turn squelch off when listening on the ground---to be able to pick up
weak signals better). So I wonder if you hear the carrier still on and
repeating noise from the the uplink when no one was talking? That is a
pretty wide use of spectrum because it is pretty loud.

My goof - that's exactly what it was. Didn't recall that from the past but
I don't think I've ever monitored a pass before with so little voice
traffic. Thinking back, every single pass that I downloaded telemetry from
in the past was nearly full of voice traffic.
Thanks!

You see, Dave, this is way more information that I have managed to gather
in the whole of 2015. Thank you so much for that!
Fair enough, I didn't go to the symposium, but a whole lot of other people
didn't go, and we have no way to know otherwise, which I find a shame.
All your points are well understood. I only and very dearly hope that
what's possibly flying on the HEO is NOT the digital voice thing they are
talking about for the geostationary one. Fine on the 5/10 frequency
combination. That'll be a nice challenge!
One thing I don't understand: if they remove the engine, how does the HEO
bird get into high orbit?
Thanks again and 73.
