Narrative:

Air carrier X, upon arrival pit terminal area, while on vectors for visual approach runway 28L frequency 108.9, we tuned and tried to identify the ILS frequency for runway 28L. We could hear a radio station on the localizer frequency. The radio was tuned to 108.9, the communication panel set up to navigation and audio selection to range. The sound did not change in intensity as we neared the field. I asked approach if the localizer was indicating normal. They said yes. I then told them (controller) that we were receiving radio station over the localizer frequency and if there was another aircraft in the area that could also check the identifier. Another aircraft, a different air carrier in a different type airplane, also noted the noise of a radio station on the localizer frequency. We both informed approach control and both aircraft landed normally in pit. While on final, music was still going on and the localizer and/or ILS was or did appear normal -- both azimuth and GS. Notified both FAA and union safety of the problem.

Title: ACR X RECEIVED RADIO STATION INTERFERENCE ON RWY 28L LOC FREQ 108 PT 9.

Narrative: ACR X, UPON ARR PIT TERMINAL AREA, WHILE ON VECTORS FOR VISUAL APCH RWY 28L FREQ 108.9, WE TUNED AND TRIED TO IDENT THE ILS FREQ FOR RWY 28L. WE COULD HEAR A RADIO STATION ON THE LOC FREQ. THE RADIO WAS TUNED TO 108.9, THE COM PANEL SET UP TO NAV AND AUDIO SELECTION TO RANGE. THE SOUND DID NOT CHANGE IN INTENSITY AS WE NEARED THE FIELD. I ASKED APCH IF THE LOC WAS INDICATING NORMAL. THEY SAID YES. I THEN TOLD THEM (CTLR) THAT WE WERE RECEIVING RADIO STATION OVER THE LOC FREQ AND IF THERE WAS ANOTHER ACFT IN THE AREA THAT COULD ALSO CHK THE IDENTIFIER. ANOTHER ACFT, A DIFFERENT ACR IN A DIFFERENT TYPE AIRPLANE, ALSO NOTED THE NOISE OF A RADIO STATION ON THE LOC FREQ. WE BOTH INFORMED APCH CTL AND BOTH ACFT LANDED NORMALLY IN PIT. WHILE ON FINAL, MUSIC WAS STILL GOING ON AND THE LOC AND/OR ILS WAS OR DID APPEAR NORMAL -- BOTH AZIMUTH AND GS. NOTIFIED BOTH FAA AND UNION SAFETY OF THE PROB.
