WASHINGTON DEP CTL GAVE US A VECTOR HDG OF 160 DEGS OFF THE DCA 185 DEG RADIAL AND CLRED US TO CLB TO 14000. THEY DID NOT INSTRUCT US TO INTERCEPT J61. PRIOR TO XING J61; DEP CTL INSTRUCTED US TO CONTACT WASHINGTON CTR ON 133.9 WE CALLED ON 133.9 AND RECEIVED NO ANSWER. WE THEN VERIFIED THE FREQ AND CALLED AGAIN. AS WE WERE DOING THIS WE CROSSED J61. WHEN WE FINALLY MADE RADIO CONTACT ON 133.9; WE WERE TOLD TO DSND TO 13000 FT AND TO TURN R IMMEDIATELY TO HDG 220 DEGS. AS WE WERE DOING THIS THE CTLR SAID HE NEEDED A HARD R TURN. WE THEN DISCONNECTED THE AUTO PLT; INCREASED THE BANK FROM 28 TO 45 DEGS; AND LEVELED AT 13000 FT. WE WERE NEVER ISSUED ANY TFC BUT BOTH OF US LOOKED FOR TFC TO THE L AND DID NOT SEE ANY. THE CTLR THEN GAVE US INSTRUCTIONS TO INTERCEPT J61. DURING THIS TIME; OTHER ACFT WHERE CALLING ON THE FREQ AND WERE NOT BEING ACKNOWLEDGED. THE FLT PROCEEDED UNEVENTFULLY TO SAVANNAH.
