Human Factors
At an uncontrolled field after making calls I taxied to Runway 3 for a northeast departure. I cleared the runway made a call and then commenced takeoff roll with all available lighting illuminated. Somewhere around V1 I noticed an aircraft starting to enter the left side of the runway at the opposite end in which I was departing. I briefly thought about aborting but thought the safer alternative would be to rotate; establish a climb; and veer to the right side of the runway. The aircraft was exiting the runway by the time we crossed the departure end of the runway; [I noticed] the aircraft was a Canadair regional jet. I was about to make a call and noticed I must had inadvertently switched the frequency to the ground frequency at some point.
BE9L pilot reported a CRJ taxied onto his runway as he was on his takeoff roll. After takeoff the pilot noticed his radio was tuned to Ground frequency.
