Airport; Human Factors; Procedure
During taxi on ground control I crossed the hold line to runway 04R at SFF without clearance. This occurred as I was changing to tower frequency as instructed by ground. After crossing the hold line I immediately stopped and turned around. There was no other traffic at the airport. I believe that I was distracted by changing radio frequencies while taxiing. In the future I will stop taxiing to set radios to requested frequencies. I am an instructor and will review this with students and pilots getting flight reviews.
Instructor pilot reports crossing the hold line for Runway 4R at SFF (a complex intersection and HS1); while changing frequency to the Tower at Ground Control's request.
