Narrative:
As the PNF, I was completing the inrange check which included a call to company. I told the first officer I would be off the #1 radio while using the #2 radio for our inrange call. While I was off, the first officer answered a call that was for an small aircraft twin with a similar sounding call sign. Our heading was 180 degree. The first officer turned to 060 degree which was for the small aircraft twin. When I returned to the #1 radio I assumed the 060 degree heading was our base leg for the approach. Upon querying the controller he told us the 060 degree heading was for the small aircraft twin and we were to be on a 180 degree heading. We returned west/O conflict. As per company procedure the turn to 060 degree was read back to the controller who evidently did not catch our error. This incident emphasizes the need for us all to make sure we listen up on the radio especially with the increasing volume of air traffic.

Title: ACR COMMUTER TAKES HEADING CLRNC INTENDED FOR ANOTHER ACFT AND ATC HEARBACK FAILURE RESULTS IN HEADING DEVIATION.
Narrative: AS THE PNF, I WAS COMPLETING THE INRANGE CHK WHICH INCLUDED A CALL TO COMPANY. I TOLD THE F/O I WOULD BE OFF THE #1 RADIO WHILE USING THE #2 RADIO FOR OUR INRANGE CALL. WHILE I WAS OFF, THE F/O ANSWERED A CALL THAT WAS FOR AN SMA TWIN WITH A SIMILAR SOUNDING CALL SIGN. OUR HDG WAS 180 DEG. THE F/O TURNED TO 060 DEG WHICH WAS FOR THE SMA TWIN. WHEN I RETURNED TO THE #1 RADIO I ASSUMED THE 060 DEG HDG WAS OUR BASE LEG FOR THE APCH. UPON QUERYING THE CTLR HE TOLD US THE 060 DEG HDG WAS FOR THE SMA TWIN AND WE WERE TO BE ON A 180 DEG HDG. WE RETURNED W/O CONFLICT. AS PER COMPANY PROC THE TURN TO 060 DEG WAS READ BACK TO THE CTLR WHO EVIDENTLY DID NOT CATCH OUR ERROR. THIS INCIDENT EMPHASIZES THE NEED FOR US ALL TO MAKE SURE WE LISTEN UP ON THE RADIO ESPECIALLY WITH THE INCREASING VOLUME OF AIR TFC.
