AMSAT Seeks Volunteers to Support Phase 4 “Five and Dime” Ground Terminal
Established less than 1 year ago, AMSAT’s all-volunteer Phase 4 Ground
Terminal team has made significant strides in developing an ensemble of
solutions to support the so-called “Five and Dime” (5 GHz and 10 GHz)
strategy AMSAT has embraced for microwave satellite projects. Prompting the
effort is the planned launch of a geosynchronous military satellite in the
2018 timeframe, which could play host to an Amateur Radio payload operating
on the two microwave band. The overarching project, which also includes a
complementary Phase 4 Space team, is exploring new territory and innovative
solutions, and it’s seeking volunteers from among the technically savvy
the Amateur Radio community.
“We’re going to make it as awesome as possible,” Ground Station team lead
Michelle Thompson, W5NYV, told ARRL. The project not only would support the
Phase 4B geosynchronous launch but provide solutions for the Phase 3E
high-Earth orbit satellite, and receiver support for AMSAT’s entry into the
NASA Cube Quest Challenge, which would go to the moon.
Thompson said the compelling technical reason for using 5 GHz and 10 GHz is
the ability to use high-bandwidth modes on those bands. In addition, “the 5
and 10 GHz bands are popular elsewhere, and other projects are embracing
band complement,” she noted. Another advantage would be to raise Amateur
Radio’s profile on the two bands and perhaps “shake things up” there for
terrestrial use. “The 5 and 10 GHz bands are a compromise that’s working
really, really well,” Thompson said.
The US Air Force will control the geosynchronous satellite. Virginia Tech,
Millennium Space Systems (MSS), FEMA, various clubs as well as AMSAT and
are partners in or are supporting the project. A formal memorandum of
understanding is pending.
“We’re currently exploring the Amateur Radio implementation of a very
and exciting open standard called DVB-S2X for the downlink,” Thompson
explained, noting it offers a variety of modulation and coding. Earth
will use their individual radios, transmitting a digital signal — probably
something called Offset QPSK (O-PSK) — directly to the satellite, with each
getting its own channel in a frequency division, multiple access (FDMA)
scheme. “This is an elegant way to design an efficient and advanced
communication system and allows technical volunteers to experiment with the
basics of cognitive radio — radio that can sense the environment and
take full advantage of the capabilities the hardware offers,” she said.
Groundsats and a “Big Honking SDR”
Phase 4 radios will be designed to work not just with the impending
geosynchronous satellite but through terrestrial microwave “Groundsats,”
which, Thompson said, “are essentially satellite simulators that let you
and use the radio terrestrially.” Phase 4 radio designs also could be
configured to use modulation schemes that are better able to deal with
Amateur Radio Access Points (ARAPs) — essentially signal aggregators —
allow legacy radios, FM hand-held transceivers, or emergency traffic
to use the satellite from any point where an ARAP can be deployed,
the input for uplink to the satellite. Hams within ARAP range would be
use the Five and Dime terrestrial network just as if they were operating
through a satellite.
“The Groundsat, which is doing the same job as the satellite payload, has a
big honking SDR on it,” Thompson said. Groundsat equipment has arrived
in use in San Diego, North Texas, and at Virginia Tech, and Groundsat
development is under way at those sites. A fourth site would be at Morgan
State University in Maryland.
Doing It on the Cheap
“Five and Dime” also reflects the project’s economics. AMSAT Board
Virginia Tech Research Professor Bob McGwier, N4HY, recently explained
AMSAT-BB that the Ground Team’s work is “an effort to design an inexpensive
ground terminal for amateurs that would cost tens of thousands of dollars
commercially, for as much under $1000 as we can get it.” In contrast to the
Space Team’s work, which, he said, is taking place “under the cloak of ITAR
(International Traffic in Arms Regulations),” the Ground Team’s SDR is
“completely open source, open specification” and “easily reprogrammed to do
many different kinds of missions just by changing the software.”
“We welcome any interested technical volunteers to apply to the technical
volunteer program at AMSAT and become part of the team,” Thompson said. To
volunteer for the Phase 4 Ground Team, provide your contact information on
AMSAT’s Engineering Team contact form. Thompson’s weekly “Phase4”
updates are available via YouTube. Additional development documentation is
posted on GitHub.

Japanese Ham Radio Satellite Launched
Yasutaka Narusawa JR2XEA posted on the AMSAT-BB:
Feb. 17 17:45JST(08:45UTC), ChubuSat-2 and ChubuSat-3 has been launched on
the H-IIA F30 launch vehicle. After separation, both satellites start
transmitting beacon message. I hope you receive our message and report to
us, thank you.
Yasutaka Narusawa JR2XEA provides the following information on ChubuSat-2/3:
Nagoya University(NU) and Mitsubishi Heavy Industries(MHI) developed 50kg
microsatellite ChubuSat-2(NU) and ChubuSat-3(MHI). These satellites have
amateur VHF receiver and amateur UHF transmitter, and will be launched
12 2016 from Tanegashima, Japan. Komaki Amateur SATCOM Club operates these
satellites from Komaki, Japan.
After the satellite separation, each satellite will transmit UHF CW beacon
message including battery voltage etc. which is very important
our initial and critical operation. So we are very happy if you receive
beacon message and report to us email:
chubusat2 at frontier.phys.nagoya-u.ac.jp
In following web site, we show the information(frequency, format, TLE, etc.)
about ChubuSat-2 and ChubuSat-3. If we have your report, we will show your
report in this page.
Both satellite will provide the message exchange service. After the on-orbit
checkout of the satellite(maybe one month after launch), you can use this
service, sending your message with VHF uplink, then your message is
the on-board memory. By sending inquiry message, anyone can read your
with UHF downlink.

I heard 2.4GHz signal many times in this orbit. The spurious signal will
be heard lower than about 56kHz from the nominal frequency, it may sound
rather strongly. The followings are the image that I received this real
signal and spurious signal. At the 2400.244 MHz, I heard the clear and
stable sound of them. Perhaps it might not be a spurious signal.
This deviation signal might be the real signal of HORYU-4 2.4GHz.

New AO7 Distance Record
Satellite Friends and Colleagues,
I wanted to share with everyone that on February 10th, at 2009UTC I made
a scheduled contact with Eduardo, PY2RN, using AO-7 Mode B, from
'Shinnal Mountain' just west of Little Rock, Arkansas. My 10 digit grid
locator for the contact was EM34ST20SC, and Eduardo's station is located
at GG66LW77JQ in Vinhedo/SP, Brazil. Using the
website for reference, this equates to 8030.895 km which we believe to be
a new record for AO-7 Mode B. I've been extremely busy this past week, but
I had a few folks request that I share a little background behind the
contact, so here we go.
Back on January 24th, I was on an AO-7(B) pass looking for Gustavo,
PT9BM. While not a record distance, Gustavo's QTH is just shy of 7500km
away from me, so I was up on my mountain, specifically in a spot with
great a great southeastern view of the Horizon. As the bird came into
view, while scanning the passband, I heard Eduardo, PY2RN, calling CQ. I
tried to answer him, but his signal disappeared quickly after that, and
I went ahead and had a great QSO with Gustavo, and didn't think anything
else of it until later that night when I decided to look up the station
I had heard. To my astonishment, Eduardo was 8030km away, which was way
beyond the theoretical range AO-7, even with elevation assistance. I
promptly emailed Eduardo and we both agreed to try and make a contact,
even though the math said it shouldn't be possible.
At this point the random luck that had let me hear Eduardo on the 24th
seemed to elude us. We attempted contacts on the 26th, 28th, and 30th
all to no avail. After recalculating windows, our next shot was on
February 8th. WinListen (from Sat32pc) calculated a 3 second window on
the 8th, followed by 5 seconds on the 10th. The day of the 8th came, and
we prepared for the attempt. Murphy once again seemed to haunt us
though, as we successfully heard the calls and grids of each other, but
strong CW QRM was hitting the bird so hard that the intelligibility was
low and, more importantly, neither of us had a camera running. We
decided to not count the QSO due to these reasons. The good news was
though, we both heard each other (the first time that had happened) and
our frequency coordination was spot on. We knew it could be done, we
just needed a little luck.
Finally, on February 10th, we got a bit of a break. We had already
determined that 5 seconds was simply not enough time to do a proper "QSL
thanks for the grid, have a great day" type of chat, so we both agreed
to simply repeat 'your call / my call / grid / report' rapidly, much in
the same way a digital or contest contact is made. At 2009UTC, both
stations cleanly heard the others call and grid, completing the
contact. It was extremely rapid, and very weak, but clear. Eduardo's
side of the QSO turned out way better than mine did, and he has uploaded
a recording of it to YouTube here:
After all my work towards low-elevation contacts from mountain-tops, I
think this is approaching the limits of what can be done on AO-7. This
was by far the hardest sked I've ever attempted, and with the contact
window measured in mere seconds, it leaves absolutely no room for error.
Had I not heard Eduardo's call at random on the attempt with Gustavo, I
doubt I would have even pursued this as something that was possible.
That said, wow.. what a rush
Big thanks to Eduardo, PY2RN, for humoring my obsession with making
ultra long-distance QSOs on the birds, and for sticking with it until we
finally made it work. Good DX my friend. Also thanks to Gustavo (PT9BM)
for persuading me to point my arrow to the South, and Drew (KO4MA) for
acting as a spotter during one of the passes to see just how far apart
we were from each other. Appreciate it guys.
If anyone has any questions or comments, I'm happy to field them. Until
then, catch you on the birds! 73!
Dave, KG5CCI also posted on the AMSAT-BB that he was using an "Alaskan"
( 4 elements on 2m, 10 elements on 70cm) held by hand, running 10'
LMR-240 into an Icom 821h, manually tuned.
"Everything is run from a LiFePo4 battery, and I pretty much exclusively
operate portable mountain-top with unobstructed horizon views in the
I'm planning to work", reported Dave.
Also on the AMSAT-BB Eduardo, PY2RN wrote that he used:
"RX: Funcube pro plus + SDR# V.1430 (with great NB capabilities) + Yagi-Uda
11el CP + Mirage KP-2 pre-amp.
TX: TS-2000x + Yagi-Uda 20el CP Tracked by Satellite Tracking embedded into
SDR-RADIO V2 software suite + GS-232/G-5400
Coax: RFS RGC213 15m long
And a clear view to my N/NW bound which allows to hear a little after
most of times.
Put together again an old P3 sat setup sitting in storage for many
added the SDR fun to it."

ARISS Information Sessions
Host a Real-Time Conversation With Crew Members Aboard the International
ARISS-US is now accepting proposals from U.S. schools, museums, science
centers and community youth organizations to host an Amateur Radio on the
International Space Station, or ARISS, contact between Jan. 1 - June 30,
2017. To maximize these radio contact opportunities, ARISS-US is looking for
organizations that will draw large numbers of participants and integrate the
contact into a well-developed education plan. Proposals are due April 15,
Using amateur radio, students can ask astronauts questions about life in
space and other space-related topics. Students fully engage in the ARISS
contact by helping set up an amateur radio ground station at the school and
then using that station to talk directly with a crew member on the
International Space Station for approximately 10 minutes. ARISS provides
experienced mentors and relies on local amateur radio volunteers to help
organizations obtain the technology required to host this once-in-a-lifetime
opportunity for students.
To help organizations in preparing their proposals, the ARISS program
coordinator will offer hourlong online information sessions. These are
designed to provide more information regarding U.S. ARISS contacts and the
proposal process, and offer an opportunity to ask questions. While attending
an online information session is not required, it is strongly encouraged.
Informational sessions will be offered Feb. 29, 2016, at 4 p.m. EST and
March 10, 2016, at 7 p.m. EST.
Advance registration is necessary. Email ARISS (ariss at arrl.org) to sign up
for an information session.
