Narrative:

2 separate air carrier flts -- flight abc and flight xyz -- on sep/xa/00. Both departed runway 27 cvg and encountered 'bleed over' on cvg tower frequency 118.3. Both times my MD88 aircraft was in position for takeoff on runway 27 and received frequency bleed over from what sounded like cvg ground control frequency. We could not isolate the bleed over to either cvg 121.3 or 121.7. We did report both occurrences to cvg tower frequency 118.3. This is a potential safety hazard due to the bleed over interfering with tower communication on cvg intersecting runways 9/27 and 36L/18R.

Original NASA ASRS Text

Title: MD88 CREW RECEIVED RADIO BLEED THROUGH WHILE ON CVG TWR FREQ FROM THE CVG GND FREQ.

Narrative: 2 SEPARATE ACR FLTS -- FLT ABC AND FLT XYZ -- ON SEP/XA/00. BOTH DEPARTED RWY 27 CVG AND ENCOUNTERED 'BLEED OVER' ON CVG TWR FREQ 118.3. BOTH TIMES MY MD88 ACFT WAS IN POS FOR TKOF ON RWY 27 AND RECEIVED FREQ BLEED OVER FROM WHAT SOUNDED LIKE CVG GND CTL FREQ. WE COULD NOT ISOLATE THE BLEED OVER TO EITHER CVG 121.3 OR 121.7. WE DID RPT BOTH OCCURRENCES TO CVG TWR FREQ 118.3. THIS IS A POTENTIAL SAFETY HAZARD DUE TO THE BLEED OVER INTERFERING WITH TWR COM ON CVG INTERSECTING RWYS 9/27 AND 36L/18R.
