Narrative:
Flight progressed normally until just prior to turn in for the ILS. Captain mistook call for aircraft to mean frequency. Aircraft crossed approach course while off correct approach frequency. When we returned to proper frequency, we received an 'immediate left turn' back to intercept. On the new heading, autoplt was engaged for a coupled approach, but did not have time to settle and did not capture localizer. Autoplt was disengaged and flown manually to recapture until 600', at which time crew elected to go around. Correction would be for closer attention to frequency instructions by crew.

Title: FLT CREW OF LGT MISREAD TRIP NUMBER FOR NEW APCH FREQ. CHANGED FREQ. LOST COM.
Narrative: FLT PROGRESSED NORMALLY UNTIL JUST PRIOR TO TURN IN FOR THE ILS. CAPT MISTOOK CALL FOR ACFT TO MEAN FREQ. ACFT CROSSED APCH COURSE WHILE OFF CORRECT APCH FREQ. WHEN WE RETURNED TO PROPER FREQ, WE RECEIVED AN 'IMMEDIATE LEFT TURN' BACK TO INTERCEPT. ON THE NEW HDG, AUTOPLT WAS ENGAGED FOR A COUPLED APCH, BUT DID NOT HAVE TIME TO SETTLE AND DID NOT CAPTURE LOC. AUTOPLT WAS DISENGAGED AND FLOWN MANUALLY TO RECAPTURE UNTIL 600', AT WHICH TIME CREW ELECTED TO GO AROUND. CORRECTION WOULD BE FOR CLOSER ATTN TO FREQ INSTRUCTIONS BY CREW.
