Narrative:

A shorts departed koa and was vectored around inbound traffic. When the aircraft was clear of traffic; it was given a 070 heading to join V3 to mue; V3 to paris V2 ito. When I saw the aircraft cross V3 and was 1-2 miles right of course; I advised that the aircraft that it was right of course. The pilot asked me for a radar vector back on course; the aircraft was at 7;000 ft. I advised that I couldn't vector because the aircraft was below my MVA. I suggested that the aircraft turn left to join V3 and issued 9;000; 8;000 was the MVA in that area. When the aircraft was over mue; I advised; but the aircraft still looked like it was going off course. The aircraft was in my 16;000 MVA at one point. I asked the pilot if he/she was having navigational problems. The pilot said he/she dialed into 112.2 instead of 113.3 for the mue VOR and that everything was fine. I told the pilot it was very mountainous in that area and to be very careful.

Title: HCF Controller described a below MVA event when an IFR aircraft continued to make course errors; the pilot later indicating the reason for the errors was an incorrect NAVAID frequency selection.
