audioguru Posted March 21, 2007 Report Share Posted March 21, 2007 Try connecting to the motor two 0.1uF ceramic disc capacitors with very short leads. Each capacitor from each terminal to the motor's metal case.It would be difficult to filter the radio signals. If all the interference is filtered out then the radio won't pick up stations.
