Narrative

APCHING RWY 3R FOR TKOF WE WERE ADVISED TO CONTACT TWR ON 128.75. AS B757 LANDED WE WERE CLRED INTO POS TO HOLD WITH A COMMUTER ON 4 MI FINAL. WE WATCHED THE B757 CLR RWY. I HAD ENG PWR PARTLY APPLIED BUT HEARD NO CLRNC FOR TKOF. I COULD SEE ACFT APCHING FROM BEHIND ON TCASII. WE CALLED TWR AND GOT NO ANSWER. WE TRIED THE OTHER TWR FREQ ON RADIO #2 AND ADVISED THEM WE COULD NOT HEAR TWR ON 128.75. WE DID THIS AS I VACATED THE RWY. WHILE THIS WAS TAKING PLACE THE COMMUTER WENT AROUND. AS WE CLRED THE RWY WE COULD AGAIN HEAR TWR ON 128.75. WE EXPLAINED THE SIT AND WERE TOLD NO PROB AND WERE SUBSEQUENTLY CLRED FOR TKOF. SEVERAL YRS AGO WE WENT THROUGH THIS SAME PROB AT DTW ON RWY 3C. I DON'T REMEMBER THE FREQ; BUT WHEN OUR TAIL WAS TURNED AWAY FROM THE TWR WE COULD NOT HEAR THE TWR. THIS IS THE ONLY ARPT I GO TO THAT WE LOSE RADIO CONTACT WITH TWR ON THE RWY. I DID NOT KNOW THIS PROB STILL EXISTED IN DTW. I WILL SET TWR FREQ IN COM #2 IN THE FUTURE BUT I AM NOT CERTAIN IT WILL HELP. IT IS NOT AN ACFT PROB. I FEEL IT IS A BLIND SPOT. I DON'T KNOW WHAT THE CORRECTIVE ACTION WAS ON RWY 3C BUT WE NEED IT FOR RWY 3R. I AM THANKFUL IT WAS VFR AND THE COMMUTER COULD SEE US SITTING ON THE RWY. IT IS DEFINITELY A SAFETY PROB. I MADE A PIREP TO TWR AFTER WE DEPARTED AND WE WERE ABOVE 10000 FT. THE TWR CTLR SAID SHE REMEMBERED THE PROB ON RWY 3C BUT THIS WAS THE FIRST TIME SHE WAS AWARE OF THE PROB ON RWY 3R. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: I CONTACTED THE FACILITY QUALITY ASSURANCE STAFF MEMBER FOR MORE INFO. QUALITY ASSURANCE IS UNAWARE OF ANY FREQ BLIND SPOT ON ANY OF THE RWYS. RPTR SAID THAT ALL XMITTERS ARE AT THE SAME SITE LOCATION.
