    Exclamation FR24 Receiver produces heavy noise. EMI/RFI

    Hello forum.
    I noticed that the FR24 receiver (F-EDDT2) causes strong interference around long wave and medium wave.

    Receiver ON

    Receiver OFF

    Is there any known workaround? Ferrite clamps and so on doesn't work
    I don't want local authorities to visit me because of that

    Does this use an external power supply? Perhaps it is the PSU that is generating RFI rather than the receiver itself?

    Yes, the power supply is original from FR24.
    I also believe that comes from the power supply and will ask the support for a new one.

    I remember giving away a Panasonic plasma TV that screwed up reception from 200KHz upwards, all down to the switched mode supply.
