ARLS004 ARISS Ham Station in Columbus Module Is Once Again
Operational

Some 6 weeks after going silent following a spacewalk that installed
new antenna cabling, the Amateur Radio on the International Space
Station (ARISS) ham station in the Columbus module is once again
operational. The Columbus station, which typically uses the callsign
NA1SS, is the primary ARISS amateur radio station used for school
contacts and other activities. A January 27 spacewalk replaced a
coax feed line installed 11 years ago with another built by the
European Space Agency (ESA) and Airbus.

While the specific cause of the problem has not yet been determined,
a March 13 spacewalk that restored the antenna cabling to its
original configuration provided the cure. The plan to return the
ARISS cabling to its original configuration had been a "contingency
task" for a March 5 spacewalk, but the astronauts ran out of time.
The ARISS work was appended to the to-do list for astronauts Mike
Hopkins, KF5LJG, and Victor Glover, KI5BKC, to complete a week
later.

"On behalf of the ARISS International Team, our heartfelt thanks to
all who helped ARISS work through the cable anomaly investigation, troubleshooting, and ultimate repair," ARISS International Chair
Frank Bauer, KA3HDO, said. Bauer praised NASA, the ESA, Airbus, and ARISS-Russia lead Sergey Samburov, RV3DR. While the Columbus ham
station was off the air, ARISS school and group contacts were able
to continue using the ham station in the ISS Service Module on the
Russian side of the station.

During the weekend spacewalk, Hopkins swapped out a cable for the
Bartolomeo commercial payload-handling platform that had been
installed in series with the ARISS VHF-UHF antenna feed line,
returning the ARISS system to its pre-January 27 configuration.
Hopkins raised a question concerning a sharp bend in the cable near
a connector, but no further adjustments were possible.

On March 14, ARISS was able to confirm the operation's success when
Automatic Packet Reporting System (APRS) signals on 145.825 MHz were
heard in California, Utah, and Idaho as the ISS passed overhead.
ARISS team member Christy Hunter, KB6LTY, was able to digipeat
through NA1SS during the pass. With additional confirmation from
stations in South America and the Middle East, ARISS declared the
radio system operational again.

Work during the March 13 spacewalk also made Bartolomeo operational.
"Yesterday was a great day for all!" Bauer exulted. "Ad astra!"

ARLS007 Slow-Scan TV Event from International Space Station Set

A slow-scan television (SSTV) event from June 21 - 26 will focus on
amateur radio on the Space Shuttle, the Mir space station, and the International Space Station, Amateur Radio on the International
Space Station (ARISS) has announced. Transmissions will be on
145.800 MHz FM using PD120 SSTV mode.

"The ARISS team will be transmitting SSTV images continuously from
June 21 until June 26," ARISS said in announcing the upcoming event.
"The images will be related to some of the amateur radio activities
that have occurred on the space shuttle, the Mir space station, and
the International Space Station."

Transmissions will start at or about 0940 UTC on Monday, June 21 and
will end by 1830 UTC on Saturday, June 26. "Those that recently
missed the opportunity during the limited period of MAI
transmissions should have numerous chances over the 6-day period to
capture many - if not all 12 - of the images."

The ARISS SSTV blog - located at http://ariss-sstv.blogspot.com/ -
will post the latest information. Signals should be receivable on a
handheld with a quarter-wave whip antenna. Use 25 kHz channel
spacing if available.

Pass time predictions are available on the AMSAT website at, https://www.amsat.org/track/ .

ARLS008 MIR-SAT1 CubeSat Expected to Deploy from the ISS on June 22

MIR-SAT1 (Mauritius Imagery and Radiotelecommunication Satellite 1),
the first amateur radio CubeSat from the Indian Ocean island nation
of Mauritius, is expected to be deployed from the International
Space Station (ISS) on June 22.

MIR-SAT1 will carry an amateur radio V/U digipeater (a downlink of
436.925 MHz has been coordinated). MIR-SAT1 will collect images of
the Republic of Mauritius and its Exclusive Economic Zone (EEZ)
using an onboard camera.

The 1U nanosatellite was designed by a team of Mauritian engineers
and radio amateurs and built by the Mauritius Research and
Innovation Council (MRIC). MIR-SAT1 will be available to the amateur
community when the satellite is not in use for other purposes.

ARLS011 ISS SSTV Transmission Set for Late December

The Amateur Radio on the International Space Station (ARISS) team
will support Slow Scan TV (SSTV) transmissions from the
International Space Station (ISS), December 26 - 31. The images will
be related to lunar exploration.

Transmissions should be available worldwide on 145.800 MHz FM, using
SSTV mode PD120.

Transmissions are set to start on December 26 at about 1825 UTC and
end December 31 at about 1705 UTC. The signal should be receivable
on a handheld transceiver with a quarter-wave whip antenna. Use the
widest filter for 25 kHz channel spacing.

ARLS012 New Chinese Amateur Radio Satellite Could Launch on December
25

The CAMSAT XW-3 (CAS-9) amateur radio satellite has been installed
on the CZ-4C Y39 launch vehicle at the Taiyuan Satellite Launch
Center in China, and related work is in progress as planned,
CAMSAT's Alan Kung, BA1DU, reports.

"If all goes well, the satellite will be launched on December 25,
2021." The orbit will be a circular Sun-synchronous orbit with an
altitude of 770.1 kilometers. The XW-3 (CAS-9) user manual has more
details.

The 100 mW linear transponder will have an uplink frequency of
145.870 MHz and a downlink frequency of 435.18 MHz (transponder
passband is 30 kHz, inverted). The satellite will have a CW beacon
on 435.575 MHz.

ARLS002 Eight-Satellite TEVEL Mission to Launch on January 13

The TEVEL mission, which consists of eight satellites carrying
amateur radio FM transponders, is set to launch on January 13 at
1525 UTC on the SpaceX Falcon 9 Transporter-3 mission, which also
carries AMSAT-Spain's (AMSAT-EA) EASAT-2 and HADES satellites.
(Please see 2022 Space Bulletin ARLS001 for more information about
the AMSAT-EA satellites.)

The TEVEL satellites were developed by the Herzliya Science Center
in Israel.

All eight satellites will use the same frequencies, as long as their
footprints overlap, and only one FM transponder will be activated at
a time. Beacon transmissions will be on 436.400 MHz (9,600 bps
BPSK). The uplink frequency of the FM transponders is 145.970 MHz,
and the downlink frequency is 436.400 MHz. The satellites were built
by eight schools in different parts of Israel.
