B727 CREW OVERSHOT THE CLRED INTERCEPT RADIAL ON DEP FROM PHL.

Narrative

THIS PROB STARTED WHEN THE CAPT FAILED TO PAY ATTN WHEN I WAS BRIEFING THE DEP CLRNC. THE CLRNC WAS: PHL 6; RADAR VECTORS TO JOIN THE POTTSTOWN 320 DEG RADIAL TO INTERCEPT J64 RAVINE DIRECT PHILLIPSBURG THEN AS FILED; SQUAWK XXXX. I HAD SET POT 116.5 ON NAV SIDE WITH THE 320 DEG RADIAL SET IN THE OBS (COURSE) WINDOW. DEP WENT NORMAL UNTIL WE CROSSED POTTSTOWN VOR. I REMAINED ON THE 320 DEG HDG AND THE CAPT CHANGED MY VOR FREQ TO WHAT I THOUGHT WAS RAVINE VOR 114.6. AFTER ABOUT 2 OR 3 MINS; CTR INQUIRED ABOUT WHAT WE ARE DOING; IF WE ARE INTERCEPTING J64 OR NOT. THE CAPT STATES THAT WE ARE AND TELLS ME TO TURN L; THAT WE ARE OFF COURSE. AFTER XING POTTSTOWN; I HAD PUT IN THE RADIAL FOR J64 AND AT THE TIME OF THE INQUIRY I HAD NO INDICATION OF INTERCEPTING THE COURSE. I THEN ASKED THE CAPT WHAT WAS GOING ON. HE WAS LOOKING ALL OVER THE CHART. HIS RESPONSE WAS; PUT ON THE AUTOPLT AND SEE. AFTER LEVELING OFF; I ENGAGED THE AUTOPLT AND FOUND THAT HE HAD PUT THE WRONG FREQ IN MY RADIO. HE THEN TELLS ME I WAS INTERCEPTING J60 INSTEAD OF J64. ABOUT THAT TIME CTR GIVES US DIRECT TO PHILLIPSBURG. I FEEL THIS INCIDENT COULD HAVE BEEN AVOIDED HAD THERE BEEN MORE ATTN DURING THE BRIEFING. I ALSO FEEL THE CAPT SHOULD HAVE TOLD ME WHAT HE WAS CHANGING MY RADIO FREQ TO WHEN HE SWITCHED IT. THIS ENTIRE FLT WAS A DIRECT RESULT OF NO COM FROM THE CAPT.
