    Swedens AMSAT-SM has released a short video showing communications via the amateur radio satellite AO-73 (FunCube-1) using the popular digital mode
    FT4.

    This is a short video of FT-4 communication via satellite AO-73 with SDR-Console V3.1 and Icom IC-705. It is a part of a guide that will be published later on AMSAT-SM web https://www.amsat.se/

    In the first part you will see the first screen with SDR-Console with
    Airspy Mini as receiver, audio is piped to WSJT-X. You will also see SDR-Console handle the TX Doppler correction for the IC-705 via External
    radio.

    In the second part you will see the second screen with WSJT-X connected to IC-705. The output was only one (1) to two (2) watts! You can see that
    WSJT-X is reading the Doppler corrected frequency. You will also see SDR-Console satellite tracking and PstRotator controlling the SPID RAS
    rotor.
