• Finally: looking for alien FM radio stations?

    First low frequency search for alien technology in distant galaxies

    Summary:
    Researchers have announced a groundbreaking study using the Murchison Widefield Array (MWA) in Western Australia.
    The research is the first to search for signs of alien technology in galaxies beyond our own,
    focusing on low radio frequencies (100 MHz).
    This new approach looks at distant galaxies,
    making it one of the most detailed searches for super civilizations -- those more advanced than ours.

    Would be interesting to hear their music :-)

    Not only in town here, in house too:
    https://www.panteltje.nl/pub/floor_warts_IXIMG_0790.JPG
    and that is only a few of those in use...
    OTOH over here, outside with a decent antenna, it is still OK.
    Small village, some distance between the houses..

    At higher frequencies we have radar interference..
    rotating radar just a few km away from here.
    Some satellite channels have an interference pattern every few seconds.

    https://panteltje.nl/pub/radar_spectrum_sidebands.gif
    that 1.37 GHz is picked up by the satellite dish LNB output
    Some radios pick it up to and give a click every few seconds,
    very strong radar signal, rotating dish.
    I think they are looking for Russian or US invaders...

    Yes, am looking at the source lists now
    https://www.mrao.cam.ac.uk/projects/surveys/6C/data/README
    no attempt at demodulation as far as I can see.
    A lot happened as to modulation since the 1993
    Also with all that quantum stuff we may get better sensitivity these days..

    Don't get your hopes up. The best chance is relatively nearby stars in
    our own galaxy - might just have enough signal to noise then if we catch
    them between inventing the thermionic valve and discovering spread
    spectrum transmission (which looks like noise anyway).

    We, earthlings, make so many RF noises... as do our spacecraft.
    Voyager is still calling home I think.
    There could be alien radio probes on their way.

    DTIC reports have a wide range. A few are very good. Typically the
