    I am using, but decode offline only.

    The stepps are in this order:

    - in ubuntu start the wine AO40Rcv.exe

    - in a browser I start to record a sample wav file from a websdr,s nb beacon signal. About 1 Mb is enough, because the beacon text and data arrive in a loop. Used the Audio recording menu of the websdr.

    - in the running AO40Rcv menu choose the Input Source, on the Select Input Source panel clikk the Use Wav File input checkbox, and from the file menu choose the recorded wav file

    - in the Output Settings menu on the Data Output Display/Setup panel choose your callsigne, an in the Select Folder menu select a directory path and filename

    - Clikk one of the 2 options starting "Log to File... text.

    - Choose OK to close this menu

    - Choose Signal F1 menu at the left side, if you want to see something in the black window.

    - Start the processing with the Start F12 button.

    - After the processing finished, check the log file in the choosed path.

    Here is a decoded beacon text example. Its format has DOS type carriege returns, not nice in linux:

    There are 3 special satellite in orbit since december, with similar devices you referred:

    This are the HawkEye360, and some weeks ago they started the first test on board, geolocating signals in wide frequency range.

    It will be a business based activity, but, maybe in the test time, they accept some voloutair based request too: recording some signals over the part of Es'hali's coverage area, in 3 different satellites.

    Here is the news about the test time:

    Some info about the satellites:

    This is the SDR platform, they use:

    And this is a presentation on gnu-radio conference, about the software side:
