Narrative:

Center advised us, upon passing lake henry VOR (lhy), we were approximately 6 mi north of V-58, our assigned airway. Center requested our outbound radial from lhy to which I replied 088 degrees. We immediately corrected to the right, however, we were still not sure why our #1 navigation was showing us centered on the airway. I actually looked at the VOR frequency set in #1 navigation 3 times before I realized it was tuned to williamsport (ipt) VOR! Prior to discovering the above, we had tuned #2 navigation to lhy VOR when center advised us we were on V-58 our #2 navigation, which was properly set, indicated we were south of the airway! Once lhy VOR was properly tuned #1 idented on #1 VOR we did show proper airway location. The aircraft VOR check book was on board and current. On the same leg of the flight while working other VOR frequencys, both navigation units were in agreement regarding our position. We also conducted a ground vot check the same day with both navigation units showing proper alignment. Prior to center calling our position, we had been in the process of computing engine performance and true airspeed calculations. After giving the situation much thought, in the future I will properly see what I look at, identify the navigation station, and pay much closer attention to the navigation process, especially when in close proximity to navigation stations. Although there were no traffic conflictions, these are the types of mistakes that can cause those situations to arise.

Title: FLC OF CPR SMT ACFT DEVIATED FROM ASSIGNED TRACK DUE TO SETTING THE WRONG NAVAID FREQ.

Narrative: CTR ADVISED US, UPON PASSING LAKE HENRY VOR (LHY), WE WERE APPROX 6 MI N OF V-58, OUR ASSIGNED AIRWAY. CTR REQUESTED OUR OUTBOUND RADIAL FROM LHY TO WHICH I REPLIED 088 DEGS. WE IMMEDIATELY CORRECTED TO THE R, HOWEVER, WE WERE STILL NOT SURE WHY OUR #1 NAV WAS SHOWING US CTRED ON THE AIRWAY. I ACTUALLY LOOKED AT THE VOR FREQ SET IN #1 NAV 3 TIMES BEFORE I REALIZED IT WAS TUNED TO WILLIAMSPORT (IPT) VOR! PRIOR TO DISCOVERING THE ABOVE, WE HAD TUNED #2 NAV TO LHY VOR WHEN CTR ADVISED US WE WERE ON V-58 OUR #2 NAV, WHICH WAS PROPERLY SET, INDICATED WE WERE S OF THE AIRWAY! ONCE LHY VOR WAS PROPERLY TUNED #1 IDENTED ON #1 VOR WE DID SHOW PROPER AIRWAY LOCATION. THE ACFT VOR CHK BOOK WAS ON BOARD AND CURRENT. ON THE SAME LEG OF THE FLT WHILE WORKING OTHER VOR FREQS, BOTH NAV UNITS WERE IN AGREEMENT REGARDING OUR POS. WE ALSO CONDUCTED A GND VOT CHK THE SAME DAY WITH BOTH NAV UNITS SHOWING PROPER ALIGNMENT. PRIOR TO CTR CALLING OUR POS, WE HAD BEEN IN THE PROCESS OF COMPUTING ENG PERFORMANCE AND TRUE AIRSPD CALCULATIONS. AFTER GIVING THE SITUATION MUCH THOUGHT, IN THE FUTURE I WILL PROPERLY SEE WHAT I LOOK AT, IDENT THE NAV STATION, AND PAY MUCH CLOSER ATTN TO THE NAV PROCESS, ESPECIALLY WHEN IN CLOSE PROX TO NAV STATIONS. ALTHOUGH THERE WERE NO TFC CONFLICTIONS, THESE ARE THE TYPES OF MISTAKES THAT CAN CAUSE THOSE SITUATIONS TO ARISE.
