I made a trip from michigan (298) to colorado (3v5). While en route to colorado, in ZDV airspace, I was instructed to call ZDV after landing due to a variance from my assigned altitude of 8000 ft. I was experiencing moderate turbulence and was having difficulty understanding the controller and apparently missed an altimeter setting change. The radio was very busy and communications were frequently 'stepped' on. The controller requested me to report my altitude and altimeter setting, which I did. He then gave me the corrected setting and I was ordered to call ZDV on landing. I spoke with the supervisor and she asked a few questions and said she would review the tapes and may or may not contact me further. She asked why I was at 8100 ft when I was assigned 8000 ft. I did not get the altimeter change. The rest of the trip went without other problems.

Title: A PA28 SINGLE PLT OVERSHOT HIS ASSIGNED ALT WITH ZDC.
Narrative: I MADE A TRIP FROM MICHIGAN (298) TO COLORADO (3V5). WHILE ENRTE TO COLORADO, IN ZDV AIRSPACE, I WAS INSTRUCTED TO CALL ZDV AFTER LNDG DUE TO A VARIANCE FROM MY ASSIGNED ALT OF 8000 FT. I WAS EXPERIENCING MODERATE TURB AND WAS HAVING DIFFICULTY UNDERSTANDING THE CTLR AND APPARENTLY MISSED AN ALTIMETER SETTING CHANGE. THE RADIO WAS VERY BUSY AND COMS WERE FREQUENTLY 'STEPPED' ON. THE CTLR REQUESTED ME TO RPT MY ALT AND ALTIMETER SETTING, WHICH I DID. HE THEN GAVE ME THE CORRECTED SETTING AND I WAS ORDERED TO CALL ZDV ON LNDG. I SPOKE WITH THE SUPVR AND SHE ASKED A FEW QUESTIONS AND SAID SHE WOULD REVIEW THE TAPES AND MAY OR MAY NOT CONTACT ME FURTHER. SHE ASKED WHY I WAS AT 8100 FT WHEN I WAS ASSIGNED 8000 FT. I DID NOT GET THE ALTIMETER CHANGE. THE REST OF THE TRIP WENT WITHOUT OTHER PROBS.
