Narrative:
There is a large amount of interference on our ATC frequencys from local radio stations. The problem has become worse recently, and I believe it is from over-modulation. This results in our control instructions being blocked or misunderstood. This has caused numerous problems with pilot/controller confusion and unnecessary duplicate xmissions contributing to work stressloads during busy moments. This problem has also manifested itself in the frequencys used by jackson international, but to a lesser extent due to their location outside the city. Frequencys involved are: hks frequencys: 120.0 local control, 121.9 ground control. Jan approach frequency: 125.25 west, 123.9 east, 119.05 final. Jan frequencys: 120.9 local control, 121.7 ground control.

Title: CTLR CLAIMS THAT LCL RADIO STATIONS ARE FEEDING THROUGH ON ATC FREQS AT 2 FACILITIES NEARBY.
Narrative: THERE IS A LARGE AMOUNT OF INTERFERENCE ON OUR ATC FREQS FROM LCL RADIO STATIONS. THE PROB HAS BECOME WORSE RECENTLY, AND I BELIEVE IT IS FROM OVER-MODULATION. THIS RESULTS IN OUR CTL INSTRUCTIONS BEING BLOCKED OR MISUNDERSTOOD. THIS HAS CAUSED NUMEROUS PROBS WITH PLT/CTLR CONFUSION AND UNNECESSARY DUPLICATE XMISSIONS CONTRIBUTING TO WORK STRESSLOADS DURING BUSY MOMENTS. THIS PROB HAS ALSO MANIFESTED ITSELF IN THE FREQS USED BY JACKSON INTL, BUT TO A LESSER EXTENT DUE TO THEIR LOCATION OUTSIDE THE CITY. FREQS INVOLVED ARE: HKS FREQS: 120.0 LCL CTL, 121.9 GND CTL. JAN APCH FREQ: 125.25 W, 123.9 E, 119.05 FINAL. JAN FREQS: 120.9 LCL CTL, 121.7 GND CTL.
