    Default EDM static

    For the last two years, very clear FM, this year static. Any things I should look for? I checked all connections, everything looks good.

    You might check to see if the input volume level is too high and over driving it.

    Whenever I'm hunting a "static" build up in my systems, the order of checks are:
    1. Check there are no damaged cables. Check they are clean inserts (unplug them, put them back in a couple of times, then reinsert them.) This action makes sure no gunk has found a way into (or has grown on) the connection points. The plug/unplug action actually scapes the contacts. Afterward, check that they are tight.
    2. Make sure all "non-balanced lines" are not running with power cables. Balanced lines can be checked as well, but they are less susceptible to insertion noise.
    3. If static is accompanied by "hum" (and all connections are tight), try reversing any power blocks/wall warts. Move any that can be moved to a different circuit.
    4. If all else fails, use a different sound source to see if the static is in the sound source itself, or is in the wiring/amplifiers.

    I rarely get past #1. This has worked since 1971 as I grew my sound system business.

    don't forget to check the broadcast channel - possibly some new broadcast popped up and you're competing for the same channel. If that's the case you might need to broadcast on a different frequency.

    Checked all of the above. The free channels for my location all have static/no stations.
    Thanks for your inputs. I hooked up speakers to the PI, by passing the EDM, no static.

    What happens when you connect a different source to the EDM?

    I changed FM to 88.7, far less static. Thanks everyone.
