    Whining noise is heard by people I call on BT phone.

    Very odd. When I make a call via blue tooth those I call complain of a whining noise. It follows RPM, no noise when stopped and at idle. I hear no noise thru radio, AM or FM. I hear no noise when on a phone call and call is on truck BT. Can this be the alternator? Appreciate any input. Thanks...
