Narrative:

I was taxiing from terminal area via ramp to runway 21. I called a back-taxi on 122.9 CTAF. There was no response. While looking for traffic, I commenced back-taxi to runway 21 lanai. I aligned aircraft with centerline and did pretkof checks and called 'lny traffic, air carrier X is rolling runway 3 lny right turnout 2000 ft nwbound to molokai.' as I rolled approximately 50 ft down runway 21, from out of nowhere a princeville air carrier Y DH8 aircraft was on short final for runway 3 lny. I called on radio that I was on runway 21 and rolled my aircraft to the west side of runway towards grass. I continued to call on frequency that I was on runway. The other aircraft landed, a dash 8. Only after the dash 8 landed did the pilot come on frequency. He said on CTAF that he had his radio switch in the wrong direction and apologized. The wind direction at the time was 180 degrees at 17 KTS.
