Narrative:

I contacted ATIS and was given a transponder code (no heading, altitude or departure frequency). I requested runway 14 and was cleared to taxi to 14 and hold short. I did as cleared. I did my run-up and pre-takeoff checklist. I then contacted tower and advised that I was ready for departure at 14. I then heard a clearance to turn left to 090 degrees and contact departure on 125.3. I read back the clearance and took off on runway 14. Prior to takeoff I looked in both directions to be sure that there was no traffic (incoming or taking off on runway 5-23). I do this at all airports with intersecting runways. There was no other traffic. I contacted departure and was cleared to maintain at or below 2000'. I did so and read back clearance. Shortly thereafter, approach called and wanted my name and phone #. I asked if there was some problem. He said to give him my name and home phone # and we could talk about it later. I gave him my name and #. I requested he give me a # and I would call him when I got on the ground. When I called, I was told that I had not been cleared for takeoff. He said that I had been cleared to taxi in position and hold. I asked if I could listen to the tape. He said he was too busy and I could not. I called the FAA in atlanta and was referred to winston-salem. I explained what had happened and asked if he could help me to be able to listen to the tape. He said he would make some phone calls. The next day I was called by the tower and they said I could listen to the tapes. He said that there was nothing on the tape about being cleared to taxi in position and hold and that the clearance was for another aircraft. I plan to go to rdu and listen to the tape tomorrow. I have had 2 conflicting stories. I believe that I was cleared for takeoff along with heading and departure frequency. Please call me by phone and I will have more information after hearing the tapes.
