Narrative:

ZZZ is a pretty busy uncontrolled field with a lot of flight training going on; both fixed and rotor wing. I was getting ready to embark on a long cross country trip back to my home [airport]. I filed my IFR flight plan to pick up the clearance once airborne. I did a thorough preflight and run up and observed two targets on my traffic avoidance device. One had just departed and was on the crosswind leg; the other had just turned downwind. As I approached the entrance to the runway I turned my aircraft 45 degree to the right for the best possible view of any base or downwind traffic. No traffic was observed. I then announced; '[airport name] traffic. Cirrus departing runway 30 left turn out; [airport name].' as I was climbing out the pilot (possibly instructor in the R-22 scolded me and said I almost hit him. I explained that I had looked for the traffic on base and final and did not see anyone and that I had announced I was entering the runway and departing runway 30. He stated that he had called his position on base and final and that this is a very busy airport etc. I explained I certainly did not hear his announcement and that I would not knowingly launch in front of him if I had. As I turned from crosswind to downwind on my climb out he was just exiting the runway. This leads me to question how close we really were. I fly [several hundred hours] per year and I take this type of allegation seriously. The last thing I want to do is have a collision with another aircraft. Lesson learned; see and avoid is a two pilot equation; stay away from helicopters; and airfields that host a lot of training.
