SSTV Sked from ISS

Russian cosmonauts on the International Space Station (ISS) are planning to transmit slow-scan TV (SSTV) images on 145.800MHz FM using the SSTV mode PD-120.

The transmissions will be made from RS0ISS in the Russian ISS service module.

The dates are planned as the 6 August 2021 from 1050 to 1910UTC, and the 7 August 2021 from 0950 to 1555UTC.

As always, these dates and times could change depending on operations onboard the ISS.

The signal should be receivable on a handheld with a quarter-wave whip.

If your rig has selectable FM filters, try the wider filter for 25kHz channel spacing.

AO-109 (RadFxSat-2/AMSAT Fox-1E) Open for Amateur Use

AMSAT’s Engineering and Operations Teams have announced that AO-109 (RadFxSat-2/AMSAT Fox-1E) is now open for amateur use. AMSAT advises operators to use efficient modes for making contacts, such as CW or FT4, because issues with the satellite make SSB voice contacts “challenging at best.” An article in the May/June 2021 issue (Vol. 44, No. 3) of The AMSAT Journal details the various attempts to characterize AO-109 and its apparent problems.

CAPE-3 CubeSat Launched

The University of Louisiana (UL) at Lafayette student-built CAPE-3 satellite was launched on 17th January 2021. A 1-U CubeSat, CAPE-3 includes a “digipeater and experimental UHF adaptive radio.” An AX-25 telemetry downlink has been coordinated on 145.825 MHz and a 1k2 frequency-shift keying (FSK) downlink has been coordinated on 435.325 MHz, “which may burst to 100 kHz bandwidth,”.

CAPE-3 is the third cube satellite in the CAPE series. The primary educational mission is to allow grade-school classrooms to access the Smartphone CubeSat Classroom, and run interactive experiments through an experimental smartphone ground-station grid.

The secondary mission is to perform scientific experiments involving radiation detection and take pictures of Earth.

The solar-powered spacecraft, created by UL Lafayette’s CAPE Satellite Team, was launched with nine other CubeSats as part of NASA’s Educational Launch of Nanosatellites (ELaNa) program. A Virgin Orbit LauncherOne rocket attached beneath a wing of a customized Boeing 747 was dropped high above the Pacific Ocean. It climbed about 225 miles above Earth and then ejected the satellite.

The CAPE satellites are named for the university’s Cajun Advanced Picosatellite Experiment program, designed to prepare students for careers in science, technology, engineering, and mathematics (STEM) fields.
