Narrative:
Charlotte approach was unable to contact us due to me (captain) dialing in wrong frequency when switching. Noting no communications on the radio and not yet receiving a descent clearance. I rechked the frequency and realized my mistake. First officer was flying, so when I recontacted approach, they were very accommodating and fit us in with a route 360 to the runway. Main factor affecting human performance -- fatigue. Supplemental information from acn 296131: the captain made the frequency change. The wrong frequency was tuned and the error went undiscovered for 2-3 min. I believe the high workload on this short flight from avl to clt in combination with the busy arrival environment at clt combined to result in neither one of us recognizing that we were not on the proper frequency.

Title: MLG LOSS OF COMS FOR A FEW MIN DURING DSCNT DUE TO FLC SELECTING THE WRONG FREQ.
Narrative: CHARLOTTE APCH WAS UNABLE TO CONTACT US DUE TO ME (CAPT) DIALING IN WRONG FREQ WHEN SWITCHING. NOTING NO COMS ON THE RADIO AND NOT YET RECEIVING A DSCNT CLRNC. I RECHKED THE FREQ AND REALIZED MY MISTAKE. FO WAS FLYING, SO WHEN I RECONTACTED APCH, THEY WERE VERY ACCOMMODATING AND FIT US IN WITH A RTE 360 TO THE RWY. MAIN FACTOR AFFECTING HUMAN PERFORMANCE -- FATIGUE. SUPPLEMENTAL INFO FROM ACN 296131: THE CAPT MADE THE FREQ CHANGE. THE WRONG FREQ WAS TUNED AND THE ERROR WENT UNDISCOVERED FOR 2-3 MIN. I BELIEVE THE HIGH WORKLOAD ON THIS SHORT FLT FROM AVL TO CLT IN COMBINATION WITH THE BUSY ARR ENVIRONMENT AT CLT COMBINED TO RESULT IN NEITHER ONE OF US RECOGNIZING THAT WE WERE NOT ON THE PROPER FREQ.
