  • FM Modulator Noise Question

    Anyone know why my fm modulator makes an increasing background sound as I accelerate (as my rpms increase the whining noise increases)?


    thanks

      thanks MonkeyBoy. Now at least i know what its called. 1st im going to try re-grounding, 2nd ground loop isolator, and 3rd noise suppressor. Hopefully 1st step works.
