After switching to day approach frequency of 134.45 I was distracted by a passenger question in the rear of the airplane. I did not notice a lack of other aircraft on this frequency, or consider it unusual since it was a clear evening. After about 25 or 35 mi I realized that I was in ind in approach control airspace and had not received a frequency change. It was at this time that I noticed that my communication radio was tuned to a frequency of 133.45. Rather than contact day approach on 134.45 I called ind approach and advised that I had lost communications with day approach. Ind approach acknowledged my transmission, confirmed assigned altitude and advised type of approach to expect at my destination. I believe that a momentary distraction led to a mischanneling of the radio, delayed the initial call on the frequency and therefore the unintentional loss of communications with day approach control.

Title: DUE TO DISTR IN ACFT REPORTER MISTUNED RADIO FREQ AND FAILED TO CONTACT CORRECT APCH CTL FAC.
Narrative: AFTER SWITCHING TO DAY APCH FREQ OF 134.45 I WAS DISTRACTED BY A PAX QUESTION IN THE REAR OF THE AIRPLANE. I DID NOT NOTICE A LACK OF OTHER ACFT ON THIS FREQ, OR CONSIDER IT UNUSUAL SINCE IT WAS A CLEAR EVENING. AFTER ABOUT 25 OR 35 MI I REALIZED THAT I WAS IN IND IN APCH CTL AIRSPACE AND HAD NOT RECEIVED A FREQ CHANGE. IT WAS AT THIS TIME THAT I NOTICED THAT MY COM RADIO WAS TUNED TO A FREQ OF 133.45. RATHER THAN CONTACT DAY APCH ON 134.45 I CALLED IND APCH AND ADVISED THAT I HAD LOST COMS WITH DAY APCH. IND APCH ACKNOWLEDGED MY XMISSION, CONFIRMED ASSIGNED ALT AND ADVISED TYPE OF APCH TO EXPECT AT MY DEST. I BELIEVE THAT A MOMENTARY DISTR LED TO A MISCHANNELING OF THE RADIO, DELAYED THE INITIAL CALL ON THE FREQ AND THEREFORE THE UNINTENTIONAL LOSS OF COMS WITH DAY APCH CTL.
