    The AMSAT News Service bulletins are a free, weekly news and infor-
    mation service of AMSAT, The Radio Amateur Satellite Corporation. ANS
    publishes news related to Amateur Radio in Space including reports on
    the activities of a worldwide group of Amateur Radio operators who
    share an active interest in designing, building, launching and commun-
    icating through analog and digital Amateur Radio satellites.

    The news feed on http://www.amsat.org publishes news of Amateur
    Radio in Space as soon as our volunteers can post it.

    Please send any amateur satellite news or reports to:
    ans-editor at amsat.org.

    You can sign up for free e-mail delivery of the AMSAT News Service
    Bulletins via the ANS List; to join this list see: https://mailman.amsat.org/postorius/lists/ans.amsat.org/

    RadFxSat-2 Signals Detected, AMSAT Engineering Continues to Assess

    On January 27th, Brad Schumacher, W5SAT, reported copying his CW
    signal weakly via the RadFxSat-2 transponder. On the morning of
    January 28th, AMSAT Engineering and Operations confirmed these reports
    and determined that RadFxSat-2 is partially functioning, though
    signals are extremely weak. AMSAT thanks W5SAT for his report.

    We also appreciate those who joined in determining whether they could
    detect their own or other signals in recent passes today.

    At this time it is essential and we ask you: Please do not attempt to
    transmit through the transponder until further notice. This is very
    important to the next steps we are taking now.

    The next crucial step in evaluating the condition of RadFxSat-2 is to
    determine whether or not the 1200 bps BPSK telemetry beacon is
    operating and, if possible, copy telemetry from the beacon. We ask
    that everyone with 70cm receive capability listen to the beacon
    frequency of 435.750 MHz (+/-) Doppler, upper sideband (USB). Use
    FoxTelem with your receiver in order to tune and capture any telemetry
    you can. Also make sure FoxTelem is set to “Upload to server” so that
    we receive your telemetry data. If you capture a good IQ recording on
    SDR, please send a detailed description of your recording to
    foxtelem@amsat.us. We may respond with a request for your recording
    and details on how to transfer it to the AMSAT Engineering team.
    Please understand that keeping the transponder clear is essential to
    putting all power and attention to the beacon telemetry.

    Two-line elements (TLEs) are available in AMSAT's nasabare.txt
    distribution at https://www.amsat.org/tle/current/nasabare.txt.
    Available data suggests that RadFxSat-2 is OBJECT M from the Virgin
    Orbit LauncherOne launch, NORAD ID 47320, international designation

    We thank the amateur satellite community for their perseverance and
    assistance while the AMSAT Engineering and Operations teams work to
    understand and resolve the situation with RadFxSat-2.
