Narrative:

Could not get ATC to respond when we were asking for WX deviation until third call. At that time we had already deviated for level 4 WX. Controller said 'unable' any deviation whatsoever. He then declared us emergency aircraft, stated we were not in his airspace, and squawk 7700. Following the 1-2 mi deviation, we again contacted him and flight resumed normally.
