Narrative:

On initial climb out we were given a climb to 16;000 and a heading of 240; and handed off to jax center. We were unable to contact jax center due to frequency congestion and were forced to turn the aircraft to a heading of 180 to avoid level 5 convective activity at our 12 o'clock position. At that time we attempted to declare an emergency but were not sure if the controller ever received it. At a later time the controller handed us off and our flight resumed uneventfully.
