Narrative:

I attempted to contact the ixd tower on 118.9. I had copied this frequency from the airport facility directory. I am now aware that 118.9 is the frequency for kansas city approach/departure control, not ixd tower, which is 118.3. I received no response on this frequency. Under the assumption that ixd tower was now closed, I began making common TA frequency (CTAF) position reports on 118.9. I entered a left downwind for runway 22 which was illuminated and made a normal landing giving position reports on downwind, base, and final approach. As I taxied off of the runway the taxi lights went off. From my position on the taxiway I could then see the headlights of an approaching vehicle on the runway. I waited for the vehicle which pulled up next to my aircraft. As the driver exited her vehicle I stopped my engine. The driver instructed me to contact ground control on 124.3 and that tower frequency was 118.3. I then contacted ground control who informed me that the ixd tower was open, and that I had entered the air traffic area and landed without clearance. After informing me of my error the controller asked me what my intentions were. I informed the controller that I wanted progressive taxi instructions and clearance for an eastern departure. I was then instructed to back taxi on runway 22 for departure. After back taxi I contacted tower on 118.3 and was given clearance for eastern departure and takeoff. I then departed and returned to 9k4.
