by terrain, atmospheric conditions, station strength and distance from the
transmitter, Buildings or other obstructions can ·cause moment ary static, flutter
or station swapping . If you cannot keep good reception, tuning to a stronger
station will bring improvement.
Stereo Sound -All Delco Sound Systems with an FM stereo radio will switch
