- May 1 6:45 AMMy Force also has had this problem since it was new. Here is what
1) The interference is radiative. A portable radio experiences the
interference when in the car's vicinity.
2) It affects the FM band as well. I live in a fringe area where the
stations I want to hear are 50 miles away.
3) The FM interference occurs whenever the motor is turning and is
manifested as a hiss that partially or completely masks the audio.
When the motor is not turning and the accelerator is not depressed,
the hiss is gone, which is to be expected since the AC motor doesn't
need a rotating field when stationary.
4) I checked the grounding of the antenna lead and tried various
arrangements of the mesh shielding. No improvement. In fact, the
interference is no worse with the mesh zipper jacket removed from the
RGB connector. So I leave it off.
5) The RFI drops off rapidly with distance from the car, so you are
probably not bothering the reception in nearby cars.
6) Probably the easiest solution would be to mount a vertical antenna
on the rear fender of the car (vertical being the best orientation
for FM reception). Unfortunately, this would change the looks of the
