FM Radio Static while using generator

When I run my portable generator while using my FM Stereo it produces a lot of static. I was careful to purchase a generator that produces power <5% THD so as to avoid this. Is there something I can do to prevent the static?

  • Spark plug voltage radiation. Fine screen tent over entire ignition circuit then connect with wire to a nail then push nail into earth. Aluminum screen works fine and you only need to shield the ignition not the entire generator.
  • Is the FM stereo connected to the 12 volt DC system or the 120 volt AC system?

    I'm assuming that this is an inverter type generator. It's very unlikely the problem is coming to through the power lines, more likely it's radiated from the switching electronics and so probably not much simple that could be done.

    You can confirm if its coming to through the A.C. power line by borrowing a good powerline filter like sold for audio equipment. If that makes no difference when added then the problem is radiated.

    Some tin foil or a metal plate connected to the ground put near the electronics of the generator as a shield may help, but it's a long shot.
