Narrative:

At approximately XA00 CST I received an IFR clearance from midway mdw clearance delivery to go to milwaukee mke. The clearance was poorly delivered and contained discrepancies. Upon query, the clearance was reread once and possibly twice with some changes before I was satisfied that I had copied it correctly. I departed mdw about 1 1/2 hours later and flew the clearance as copied. When mdw tower handed me off to chicago radar, the controller immediately noted that my flight path was not the one he was expecting. He immediately changed my flight path to avoid a developing conflict and vectored me onto a new route to my destination. I was asked to call chicago radar on the phone after landing just before my arrival at mke. I called and talked to a supervisor at the facility. I was told that the incident was to be investigated immediately and asked for a phone number where I could be reached in about 2 hours. I gave a number and was called back in about 2 hours. I was informed that the investigation showed that the incident was deemed to be a system deviation and that I would not be involved any further. I accepted that and continued with my mission.
