FM radio tower near house

I live about 700 feet from a radio tower which transmits a strong oldies FM station. I can always hear the station faintly in my speakers. Nothing I have tried seems to get rid of this problem. I am using a Magnum Dynalab FT101A tuner with Sunfire Theater Grand II processor, 8TC kimber speaker cables. I would appreciate any help anyone could offer as I am fairly new to audio equipment and don't know what to try next. Thanks
