Using an Icom706MKII in a '93 jeep grand cherokee. The antenna is a 102" SS whip connected to the AH-4 tuner.

When I'm transmitting, the rear windshield wiper activates, stray RF for sure. Anyone have this problem or have an idea to fix it. I don't use this wiper that much so I could disconnect it if necessary.


Ideas???

Try placing a 0.01uF ceramic disc cap (rated at least 100v) across the power leads to the motor (most I have seen have a connector within several inches of the motor to allow for installation and removal).  If the motor has a metal shell or frame, check to see if it is grounded to the chassis.  Most likely it is not, and will probably be mounted on rubber cushions to absorb vibration.  Try a short piece of braid from the shell to the door, and make sure that there is a braid between the door and the body to ensure good grounding.
73, and best of luck!
