An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS) for December 24-31.

This will be a special SSTV event to celebrate the 20th anniversary of ARISS operations on the ISS.

The event is scheduled to begin on December 24 from 16:40 GMT and continue until December 31 ending at 18:15 GMT. Dates and times subject to change due to ISS operational adjustments.

Images will be transmitted on 145.800 MHz FM +/- 3 kHz Doppler shift and the expected SSTV mode of operation is PD 120.

If your radio has selectable FM filters then for best results try selecting the wider filter designed for 25 kHz channel spacing.

Launch Window for AMSAT’s RadFxSat-2 / Fox-1E Opens December 19

The AMSAT News Service (ANS) reports Virgin Orbit has announced that the launch window for their LauncherOne Launch Demo 2 mission opens on December 19th. This launch will carry AMSAT’s RadFxSat-2 / Fox-1E to orbit.

RadFxSat-2, like RadFxSat / Fox-1B, now AMSAT-OSCAR 91, is a partnership opportunity between Vanderbilt University and AMSAT and will carry a similar radiation effects experiment, studying new FinFET technology.

RadFxSat-2 is the fifth and final Fox-1 satellite built by AMSAT. The RadFxSat-2 spacecraft bus is built on the Fox-1 series but features a linear transponder “upgrade” to replace the standard FM transponder in Fox-1A through D. In addition, the uplink and downlink bands are reversed from the previous Fox satellites in a Mode V/u (J) configuration using a 2 meter uplink and 70 cm downlink. The downlink features a 1200 bps BPSK telemetry channel to carry the Vanderbilt science data in addition to a 30 kHz wide transponder for amateur radio use. Telemetry and experiment data can be decoded using FoxTelem version 1.09 or later.

FoxTelem is available at https://www.amsat.org/foxtelem-software-for-windows-mac-linux/

Participation in telemetry collection by as many stations in as many parts of the world as possible is essential as AMSAT Engineering looks for successful startup and indications of the general health and function of the satellite as it begins to acclimate to space. AMSAT will send a commemorative 3D printed QSL card to the first station capturing telemetry from RadFxSat-2.

RadFxSat-2 / Fox-1E Frequencies:

Telemetry Downlink – 435.750 MHz
Inverting Linear Transponder Uplink – 145.860 MHz – 145.890 MHz
Inverting Linear Transponder Downlink – 435.760 MHz – 435.790 MHz

Athlone students to contact ISS

Shannon Walker KD5DXB

Shannon Walker KD5DXB

An ARISS educational school contact is planned between astronaut Shannon Walker KD5DXB on the International Space Station and students at Athlone Community College, Athlone, Co. Westmeath.

The contact is scheduled on Monday December 7, 2020 at approximately 2:50 PM (1450 GMT, 1550 CET) with the link to the ISS operated by the amateur radio ground station EI1ISS.

The ISS FM downlink signal will be audible across the British Isles and Europe on 145.800 MHz +/-3.5 kHz Doppler shift. Those who do not have an amateur radio receiver or are in a different part of the world will still be able to receive the signal from space by using either of these online WebSDR radios:
Goonhilly: https://vhf-goonhilly.batc.org.uk/
Farnham: http://farnham-sdr.com/
Click on the FM mode button, and enter 145800 into the “kHz” frequency box.

It is understood the event will also be live streamed, for URL check https://twitter.com/ACCspacecall

Shannon Walker was selected by NASA to be an astronaut in 2004. She holds a Bachelor of Arts degree in Physics, a Master of Science and a Doctorate of Philosophy in Space Physics from Rice University. Walker began her professional career at the Johnson Space Center (JSC) in 1987 as a Robotics Flight Controller for the Space Shuttle Program. In 2010, she served as Flight Engineer for Expedition 24/25, a long-duration mission aboard the International Space Station that lasted 163 days. Walker served as mission specialist on the Crew-1 SpaceX Crew Dragon, named Resilience, which launched November 15, 2020. She is currently serving as Flight Engineer on the International Space Station for Expedition 64.

About ARISS:

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National  National Aeronautics and Space Administration (NASA).

The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts and mathematics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see https://www.ariss.org/
