Narrative:

We departed martha's vineyard (mvy) at XA50Z. We were handed from mvy tower to cape control. Cape control gave us a turn of 10 degrees right and a climb to 6000 ft MSL. As we turned; we acknowledged a 'TA' from our TCASII. We idented that aircraft. Right after that TA; we acknowledged an RA from our TCASII. We responded with a hard right turn and stopped the climb. I informed ATC of the RA. It took 2 calls to ATC for a response. ATC was very busy. A second controller did respond to us about our RA. I don't know if this was a supervisor or if training was being conducted. After aircraft was cleared; we continued uneventfully with the flight.

Title: CL60 FLT CREW WITH K90 TRACON EXPERIENCED TCASII RA AT 5000 FT ON DEP FROM MVY.

Narrative: WE DEPARTED MARTHA'S VINEYARD (MVY) AT XA50Z. WE WERE HANDED FROM MVY TWR TO CAPE CTL. CAPE CTL GAVE US A TURN OF 10 DEGS R AND A CLB TO 6000 FT MSL. AS WE TURNED; WE ACKNOWLEDGED A 'TA' FROM OUR TCASII. WE IDENTED THAT ACFT. RIGHT AFTER THAT TA; WE ACKNOWLEDGED AN RA FROM OUR TCASII. WE RESPONDED WITH A HARD R TURN AND STOPPED THE CLB. I INFORMED ATC OF THE RA. IT TOOK 2 CALLS TO ATC FOR A RESPONSE. ATC WAS VERY BUSY. A SECOND CTLR DID RESPOND TO US ABOUT OUR RA. I DON'T KNOW IF THIS WAS A SUPVR OR IF TRAINING WAS BEING CONDUCTED.
