LR36 FLT CREW LOSES RADIO CONTACT SHORTLY AFTER TKOF. FLY INAPPROPRIATE HDG MISTAKEN TO HAVE BEEN ASSIGNED BY TWR AT TKOF.

Narrative

BEFORE DEPARTING FROM MORRISTOWN; TN; WE RECEIVED OUR CLRNC ON THE GND FROM KNOXVILLE APCH. I COPIED BACK THE CLRNC AS CLRED TO TRI-CITIES AS FILED; CLB TO 5000 FT; FREQ 125.5 AND SQUAWK ABCD. SO THEN WE DEPARTED AND WE HAD TROUBLE CONTACTING DEP ON THE RADIO. SO AFTER REACHING 5000 FT I TOLD MY COPLT I WAS GOING TO START A TURN ON COURSE. OUR FILED COURSE WAS DIRECT HMV DIRECT TRI. SO I WAS GOING TO TURN DIRECT HMV. MY COPLT CORRECTED ME AND SAID THAT WE WERE TO FLY A 140 DEG HDG PER THE CLRNC. HE SAID THAT AFTER KNOXVILLE APCH GAVE US OUR SQUAWK HE SAID ON DEP TURN TO A 140 DEG HDG AND HE SHOWED ME THAT HE HAD WRITTEN IT DOWN. SO I TURNED TO A 140 DEG HDG AND TRIED OVER THE RADIO TO CONFIRM THE HDG. WE WERE TALKING TO TRI-CITIES APCH AND THE COM WAS DIFFICULT. NORMALLY WE WOULD BE TAKING TO KNOXVILLE DEP. SO WE WERE SOMEWHAT CONFUSED BY THIS AS WELL. BEFORE WE COULD GET A CONFIRMATION FROM TRI-CITIES ON OUR HEADING WE WERE TOLD TO CONTACT KNOXVILLE APCH. ONCE WE CONTACTED THEM WE HAD CLR COM AND THEY CLBED US UP TO 6000 FT AND TURNED US ON COURSE. THEY ALSO GAVE ME A PHONE NUMBER TO CALL ON THE GND. IT TURNED OUT THAT AFTER KNOXVILLE GAVE US OUR CLRNC THEY TOLD ANOTHER ACFT TO FLY HDG 140 DEGS AND MY COPLT MISTOOK THAT TO BE FOR US. THAT 140 DEG HDG TURNED US TOWARDS MOUNTAINOUS TERRAIN AT LOW ALT. THE PROB WAS A MISUNDERSTANDING OF A CLRNC. THE CONTRIBUTING FACTORS WERE POOR CREW MEMBER COM ON THE GND ABOUT THE CLRNC BEFORE TKOF. AND POOR RADIO COMS IN THE AIR WHEN TRYING TO RESOLVE SOME CONFUSION. THE SOLUTION IS BETTER CREW MEMBER COM ON THE GND. AND KNOXVILLE IS QUESTIONING WHETHER OR NOT THEY SHOULD MAKE CONTACT WITH DEPARTING ACFT BEFORE HAVING THEM ATTEMPT TO MAKE CONTACT WITH A DIFFERENT CTLING FACILITY.
