BAE10 PIC is confused over the fact that the 348 degree radial set in for navigation backup doesn't agree with his position as he 'follows the river' on climb north from dca. Controller verifies his position after the first officer mistakenly says that their aircraft was on 'the 348 degree radial.'

Narrative:

We departed dca runway 36 and were instructed to follow the river on departure. We also had the 348 degree radial set in from dca VOR as backup. We followed the river and noticed it was not matching the radial. Controller asked us our position. We said we were on the 348 degree radial. He said, you're supposed to be on the 328 degree radial, and gave us a phone number to call when we got on the ground. We said we were over the river and he responded, 'then that's ok.' other crew member added he should have backed me up, and was not.

Title: BAE10 PIC IS CONFUSED OVER THE FACT THAT THE 348 DEG RADIAL SET IN FOR NAV BACKUP DOESN'T AGREE WITH HIS POS AS HE 'FOLLOWS THE RIVER' ON CLB N FROM DCA. CTLR VERIFIES HIS POS AFTER THE FO MISTAKENLY SAYS THAT THEIR ACFT WAS ON 'THE 348 DEG RADIAL.'

Narrative: WE DEPARTED DCA RWY 36 AND WERE INSTRUCTED TO FOLLOW THE RIVER ON DEP. WE ALSO HAD THE 348 DEG RADIAL SET IN FROM DCA VOR AS BACKUP. WE FOLLOWED THE RIVER AND NOTICED IT WAS NOT MATCHING THE RADIAL. CTLR ASKED US OUR POS. WE SAID WE WERE ON THE 348 DEG RADIAL. HE SAID, YOU'RE SUPPOSED TO BE ON THE 328 DEG RADIAL, AND GAVE US A PHONE NUMBER TO CALL WHEN WE GOT ON THE GND. WE SAID WE WERE OVER THE RIVER AND HE RESPONDED, 'THEN THAT'S OK.' OTHER CREW MEMBER ADDED HE SHOULD HAVE BACKED ME UP, AND WAS NOT.
