Narrative:

We were given a 360 degree heading - (base leg) for runway 9R at atl. The captain turned to this heading and we awaited a turn to the dog leg, when approaching the localizer and visual centerline, and the captain called approach with no answer. I checked the radio and the frequency had dropped from 118.35 to 118.32 on its own. I immediately corrected this and called approach. They had us continue on the 360 degree heading and make a left 270 degree turn to join the localizer. No conflict was apparent on TCASII, visually or from approach control. We had flown this aircraft previously in the rotation and had the same radio problem, but did not write it up because we thought we might have bumped the radio know ourselves.

Title: COM LOST TEMPORARILY DUE TO FAULTY RADIO.

Narrative: WE WERE GIVEN A 360 DEG HDG - (BASE LEG) FOR RWY 9R AT ATL. THE CAPT TURNED TO THIS HDG AND WE AWAITED A TURN TO THE DOG LEG, WHEN APCHING THE LOC AND VISUAL CTRLINE, AND THE CAPT CALLED APCH WITH NO ANSWER. I CHKED THE RADIO AND THE FREQ HAD DROPPED FROM 118.35 TO 118.32 ON ITS OWN. I IMMEDIATELY CORRECTED THIS AND CALLED APCH. THEY HAD US CONTINUE ON THE 360 DEG HDG AND MAKE A L 270 DEG TURN TO JOIN THE LOC. NO CONFLICT WAS APPARENT ON TCASII, VISUALLY OR FROM APCH CTL. WE HAD FLOWN THIS ACFT PREVIOUSLY IN THE ROTATION AND HAD THE SAME RADIO PROB, BUT DID NOT WRITE IT UP BECAUSE WE THOUGHT WE MIGHT HAVE BUMPED THE RADIO KNOW OURSELVES.
