    ARLS010 Slow-Scan TV Transmissions from ISS Set for December 1 - 2

    Russian cosmonauts on the International Space Station (ISS) plan to
    transmit slow-scan TV (SSTV) images on December 1 - 2 on 145.800 MHz
    FM using SSTV mode PD120.

    The transmissions from RS0ISS will be part of the Moscow Aviation
    Institute SSTV experiment (MAI-75) and will originate in the Russian
    ISS Service Module (Zvezda) using a Kenwood TM-D710 transceiver.
    Transmissions are scheduled for December 1 from 1210 - 1910 UTC and
    December 2 from 1140 - 1720 UTC. Dates and times are subject to
    change.

    The signal should be receivable on a handheld transceiver with a
    quarter-wave whip antenna. Use the widest channel spacing.

    Predictions for ISS pass times are available on the AMSAT website
    at, https://www.amsat.org/track/ .

    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.
