Past AMSAT President and Director, and Amateur Satellite Pioneer Tom Clark,
K3IO, SK
AMSAT-NA Past President and ham radio satellite and digital pioneer Tom
Clark, K3IO (ex-W3IWI), of Columbia, Maryland, died on September 28 after a
short illness and hospital stay. An ARRL Life Member, he was 82. Clark
s
accomplishments are legendary, and he left a lasting footprint in the
worlds of amateur radio satellites and digital techniques.
“His long-time technical achievements, mentoring to others, and tec
hnical
leadership will be missed by his many peers and friends the world over,
said Bob McGwier, N4HY.
To honor Clark, AMSAT has rebranded its upcoming annual gathering as the
2021 AMSAT Dr. Tom Clark, K3IO, Memorial Space Symposium and Annual General
Meeting. It will take place on October 30 via Zoom. (AMSAT members may
register to attend via AMSATs Membership and Event portal.) The ev
ent will
be livestreamed on AMSATs YouTube channel.
A founding member of Tucson Amateur Packet Radio (TAPR), Clark was a
co-founder of the TAPR/AMSAT DSP Project, which led to software-defined
radio (SDR). He was a leader in the development of the AX.25 packet radio
protocol. Clark served as AMSATs second President, from 1980 until
1987.
He also served on the AMSAT and TAPR Boards.
In concert with McGwier, Clark developed the first amateur Digital Signal
Processing (DSP) hardware, including a number of modems. He developed the
uplink receivers and the spacecraft LAN (local area network) architecture
used on all the Microsats (AMSAT-OSCAR 16, Dove-OSCAR 17, WEBERSAT-OSCAR
18, LUSAT-OSCAR 19, Italy-OSCAR 26, AMRAD-OSCAR 27, and TMSAT-OSCAR 31).
McGwier said it was Clark who convinced him in 1985 that the future lay in
DSP.
“We started the TAPR/AMSAT DSP [digital signal processing] project,
and it
was announced in 1987,” McGwier recounted. “We showed in ou
r efforts that
small stations with small antennas could bounce signals off the moon, and,
using the power of DSP, we could see the signals in our computer displays.
”
This led to the software-defined transponder (SDX) for satellite work,
including ARISSat and AMSATs Phase 3E.
Clark received a doctorate in astrogeophysics from the University of
Colorado. He went on to serve as Chief of the Astronomy Branch at NASA
Marshall Space Flight Center and was a Senior Scientist at NASA Goddard
Space Flight Center, where he was principal investigator for the Space Very
Long Baseline Interferometry (VLBI) activity there.
In 2005, Clark became the first non-Russian to be awarded a Gold Medal of
the Russian Academy of Sciences for his contributions to the international
VLBI network. He is a member of the 2001 class of CQ magazines Ama
teur
Radio Hall of Fame.
In 2016, ARRL awarded Clark with its Presidents Award, to recogniz
e his 60
years of advancing amateur radio technology. On that occasion, McGwier
said, “There would be no AMSAT to inspire all of this work without
Tom
Clark. Tom…saved the organization and inspired all of us to look to
the
future and aim for the stars.”
Clark was a Fellow of the American Geophysical Union and the International
Association of Geodesy.

October 1st JAXA Epsilon Launch Carrying Amateur Radio Payloads Scrubbed,
Launch Now October 3rd
The fifth launch of JAXA's Epsilon rocket was scheduled to take place on
October 1st at 00:51 UTC. Due to ground equipment problems, the launch was
scrubbed. The launch is now scheduled to occur at the time of release of
this bulletin (00:00 UTC on October 3rd)
This launch carries four amateur radio satellites: TeikyoSat-4(TS-4),
Z-Sat, KOSEN-1, and NanoDragon.
Information about these satellites can be found at the links that follow:
TeikyoSat-4(TS-4)
Freq: 437.450 CW
https://spacesystemsociety.jimdofree.com/projects/teikyosat-project/teikyos
at-4-info/
Z-Sat
Freq: 145.875MHz CW
https://twitter.com/KOMAKI_AMSATCOM/status/1443125922010308608
Komaki Amateur SATCOM Club has an amateur radio station in Komaki City,
Japan.
The 50 kg class infrared observation microsatellite "Z-Sat" developed by
Mitsubishi Heavy Industries will be launched by the Epsilon rocket on
October 1st.
After satellite separation, Z-Sat will start transmitting CW beacon of VHF
band. The beacon signal is in Morse code and contains information such as
satellite battery voltage. This information is very important as survival
information immediately after the satellite is put into orbit.
Therefore, if you can receive the beacon signal from the satellite
immediately after the satellite launch, we would appreciate it if you could
report it.
Komaki Amateur SATCOM Club's twitter is open at the following address.
Information on Z-Sat transmission frequency, data format, orbit TLE, etc.
will be released in the future.

Apogee View - From the July/August 2021 AMSAT Journal
A Sustained FM Presence in LEO
While our volunteer engineers focus their efforts on GOLF, developing the
systems and technologies necessary for our path upward to HEO, we must not
forget our responsibility to promote amateur radio satellites and encourage
the next generation of operators and builders.
Advancing the art and science is not enough. We also need to provide an
easy entry point to amateur radio satellite communications to support of
our space education and outreach activities.
The Importance of EasySats
AMSATs Echo (AO-51) and Fox-1 (AO-85, AO-91, and AO-92) satellites
, as
well as SaudiSat-1C (SO-50) have been the most widely used amateur
satellites. What makes them so popular is their ability to provide basic
radio communications, with very simple ground station equipment, and their
ease of use. An FM repeater, even in a low Earth orbit (LEO), allows
amateur radio operators to communicate over substantial distances using
just a handheld transceiver (an HT) and a small handheld directional
antenna. Cross-continental and, if you are lucky enough to live near the
coast, transcontinental communications are possible.
These so called “EasySats” have provided countless hours of
enjoyment to
thousands and thousands of amateur radio satellite operators around the
world, making QSOs, chasing grids, and even just a chance to send out a
casual hello to an old friend. More importantly, FM satellites are
extremely valuable in providing an introduction to satellite communications
and often used for demonstrations given at schools and public events.
With AO-85s battery failure and AO-91 and AO-92 on borrowed time,
AMSAT
will soon find itself without an FM satellite in space. The time to act is
now.
The Proposal
AMSATs Strategic Plan, Objective 4.1, FM Operations gives us fairl
y
specific guidance: Develop, deploy, and support a series of 1u spacecraft
to support continued FM amateur satellite operations in low Earth orbit.
As such, any proposal must include a sustained FM presence in LEO.
The Fox-1 CubeSat series taught us some valuable lessons. First, batteries
in in a 1U CubeSat are more likely to have a three-year life span, rather
than the expected five years. Keeping battery levels above the minimal
voltage rating is critical. The popularity of AMSATs FOX-1 series
,
especially at night, when the satellite was in eclipse, was the primary
cause of their shortened battery life. Any proposal must include both
battery management and battery failsafe. The design must include
provisions that automatically switch the satellite to Low Power Mode
(beacon and telemetry only), when the battery voltage drops to a cautionary
level, and then automatically return to normal operations, when sufficient
battery power is restored. In addition, the satellite must be designed so
that when the battery fails, the transponder can continue to operate when
the satellite is in sunlight. Similarly, the design should include an
autonomous capability so that the FM repeater can operate without relying
on ground control or a functioning processor in the command, control, and
telemetry module. These safeguards and failsafes should extend the usable
life of our satellites.
Second, it is impossible to keep a strict schedule, when relying on a
free
ride” under NASAs Educational Launch of Nanosatellites (El
aNa)
initiative. Once accepted into the program and manifested on a launch, you
are at the mercy of the launch provider, and things dont always go
as
scheduled. Case in point, Fox-1D (AO-92) launched before Fox-1C (AO-95).
To ensure the launch of one satellite every three years, we will need to
purchase launches. In addition, we need to have a “flight spare
on
standby in case there is an integration inspection issue with the primary
satellite or a subsequent launch failure.
The Challenges
Every satellite project requires both people and funding. As mentioned
already, all of our engineers are consumed by our GOLF program. This
leaves us with either open-sourcing the project or purchasing a commercial,
off-the-shelf satellite. Open-sourcing would work for the initial design
process; however, there is no current precedent to allow the open-source
building of a satellite under U.S. Export Administration Regulations (EAR).
While there are many commercial companies that offer complete off-the-shelf
1U CubeSat platforms, only one includes an FM repeater that meets our
mission requirements. Purchasing a ready-to-fly CubeSat seems to be our
best course of action, given AMSAT engineers focus on GOLF, but it
comes
at a cost.
Two 1U FM CubeSats (flight model and flight spare), a 1U FM CubeSat
engineering model (without solar panels) and a 500 KM, Sun-synchronous
orbit launch will cost just over $283,000. Each additional launch, one
every three years, will cost approximately $138,000, as we would only need
to purchase one CubeSat and the launch.
So that leaves us with the big question – How are we going to pay f
or it?
An FM satellite provides a world-wide benefit. Therefore, we need to
conduct an international fundraising campaign, partner with other AMSAT
organizations, and request funding from other organizations.
The benefits of providing a sustained FM presence in LEO to promote and
support amateur radio in space far outweighs the costs, especially when we
implement a plan that allows our AMSAT engineers to continue their efforts
on our path Onward & Upward.
If approved by our Board of Directors, I hope you will support us.
