Narrative:

On apr/thu/03, at approximately XA30 we were cleared for takeoff heading 010 degrees to 5000 ft. While climbing through approximately 2000 ft, we received an RA, and responded to the TCASII command. We attempted to contact approach, but were unsuccessful due to frequency congestion. After 'clear of conflict' we began to climb and heard ATC give us 040 degree heading. We started to turn and received a second RA. We again responded to the RA. We finally contacted ATC and they said our clearance was climb to 4000 ft then turn to 110 degrees. We did not receive this clearance. I feel that we missed it during the ambient noise and maneuver of the RA. We received the first RA while heading 010 degrees. I feel that the cause of this event was a fully loaded aircraft taking off in front of us (cessna 421) and a lightly loaded CL65 (us). As we overtook our traffic ATC was unable to communicate with us due to frequency congestion.

Title: A CL65 FLT CREW EXPERIENCES A TCASII RA ON CLBOUT WHILE OVERTAKING A SLOWER C421.

Narrative: ON APR/THU/03, AT APPROX XA30 WE WERE CLRED FOR TKOF HEADING 010 DEGS TO 5000 FT. WHILE CLBING THROUGH APPROX 2000 FT, WE RECEIVED AN RA, AND RESPONDED TO THE TCASII COMMAND. WE ATTEMPTED TO CONTACT APCH, BUT WERE UNSUCCESSFUL DUE TO FREQ CONGESTION. AFTER 'CLR OF CONFLICT' WE BEGAN TO CLB AND HEARD ATC GIVE US 040 DEG HDG. WE STARTED TO TURN AND RECEIVED A SECOND RA. WE AGAIN RESPONDED TO THE RA. WE FINALLY CONTACTED ATC AND THEY SAID OUR CLRNC WAS CLB TO 4000 FT THEN TURN TO 110 DEGS. WE DID NOT RECEIVE THIS CLRNC. I FEEL THAT WE MISSED IT DURING THE AMBIENT NOISE AND MANEUVER OF THE RA. WE RECEIVED THE FIRST RA WHILE HEADING 010 DEGS. I FEEL THAT THE CAUSE OF THIS EVENT WAS A FULLY LOADED ACFT TAKING OFF IN FRONT OF US (CESSNA 421) AND A LIGHTLY LOADED CL65 (US). AS WE OVERTOOK OUR TFC ATC WAS UNABLE TO COMMUNICATE WITH US DUE TO FREQ CONGESTION.
