Narrative:

This report is to let some one know that the radios at bna airport control tower/TRACON are failing often. We get such static that we can not transmit and /or receive! This is a potentially dangerous situation. It doesn't seem that management here is taking any action! Callback conversation with the reporter revealed the following information: the reporter stated that the heavy static interference with the bna radios is still a continuing problem. Asked the reporter if he could explain when it started, exactly what happens and what frequencies are involved? The reporter explained that the heavy static interference started about 3 or 4 months ago. The reporter claims that it occurs every 2 or 3 hours and blocks the frequency for about 15 to 40 seconds. The frequencies involved are 121.9, which is a ground frequency, that bleeds through to local, 118.6. In the TRACON its' both guard frequencies and the departure east frequency, 118.4 the reporter believes its' an internal problem because the pilots can hear them but they can't hear the pilots when the static is present. Also, the static can only be heard by them at the facility, which leads him to believe the problem is with their equipment.

Title: APCH RADAR CTLR AT BNA STATES FACILITY HAS ONGOING RADIO PROBS AND THE FACILITY MGMNT IS NOT TAKING ACTION TO FIX THE PROB.

Narrative: THIS RPT IS TO LET SOME ONE KNOW THAT THE RADIOS AT BNA ARPT CTL TWR/TRACON ARE FAILING OFTEN. WE GET SUCH STATIC THAT WE CAN NOT TRANSMIT AND /OR RECEIVE! THIS IS A POTENTIALLY DANGEROUS SIT. IT DOESN'T SEEM THAT MGMNT HERE IS TAKING ANY ACTION! CALLBACK CONVERSATION WITH THE RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT THE HVY STATIC INTERFERENCE WITH THE BNA RADIOS IS STILL A CONTINUING PROB. ASKED THE RPTR IF HE COULD EXPLAIN WHEN IT STARTED, EXACTLY WHAT HAPPENS AND WHAT FREQUENCIES ARE INVOLVED? THE RPTR EXPLAINED THAT THE HVY STATIC INTERFERENCE STARTED ABOUT 3 OR 4 MONTHS AGO. THE RPTR CLAIMS THAT IT OCCURS EVERY 2 OR 3 HOURS AND BLOCKS THE FREQUENCY FOR ABOUT 15 TO 40 SECONDS. THE FREQUENCIES INVOLVED ARE 121.9, WHICH IS A GND FREQ, THAT BLEEDS THROUGH TO LOCAL, 118.6. IN THE TRACON ITS' BOTH GUARD FREQUENCIES AND THE DEP E FREQ, 118.4 THE RPTR BELIEVES ITS' AN INTERNAL PROB BECAUSE THE PLTS CAN HEAR THEM BUT THEY CAN'T HEAR THE PLTS WHEN THE STATIC IS PRESENT. ALSO, THE STATIC CAN ONLY BE HEARD BY THEM AT THE FAC, WHICH LEADS HIM TO BELIEVE THE PROB IS WITH THEIR EQUIP.
