Narrative:
In marginal VFR WX after having been cleared for an ILS to runway 21L with first officer flying aircraft, noticed that first officer had inadvertently transposed frequency and tuned in 115.1 instead of 111.5 (proper 21L ILS). Gave command to turn 30 degree left to correct back, dialed in 111.5 for him and then, since we were at the marker and supposed to call tower, I accidently, in my rush, dialed in ground control frequency instead of tower. The ground controller then directed us to go around and contact approach control for vectors for another ILS. We complied and made another ILS to an uneventful landing. Contributing factors: marginal VFR. We were lulled into complacency expecting to pick up 21L visually and therefore we didn't bother to identify the ILS frequency. ILS 21L structure, this approach requires the PNF to have his navigation radio set to carleton VOR for intersection DME instead of dxo (dtw) VOR as a result you really don't have a good reference of where the airport is during the approach.
Original NASA ASRS Text
Title: FLC OF MLG ON APCH TO 21 ILS AT DTW USED WRONG NAV FREQ AND WRONG TWR FREQ. GAR WAS INITIATED BY GND CTLR WHEN CONTACTED.
Narrative: IN MARGINAL VFR WX AFTER HAVING BEEN CLRED FOR AN ILS TO RWY 21L WITH FO FLYING ACFT, NOTICED THAT FO HAD INADVERTENTLY TRANSPOSED FREQ AND TUNED IN 115.1 INSTEAD OF 111.5 (PROPER 21L ILS). GAVE COMMAND TO TURN 30 DEG L TO CORRECT BACK, DIALED IN 111.5 FOR HIM AND THEN, SINCE WE WERE AT THE MARKER AND SUPPOSED TO CALL TWR, I ACCIDENTLY, IN MY RUSH, DIALED IN GND CTL FREQ INSTEAD OF TWR. THE GND CTLR THEN DIRECTED US TO GAR AND CONTACT APCH CTL FOR VECTORS FOR ANOTHER ILS. WE COMPLIED AND MADE ANOTHER ILS TO AN UNEVENTFUL LNDG. CONTRIBUTING FACTORS: MARGINAL VFR. WE WERE LULLED INTO COMPLACENCY EXPECTING TO PICK UP 21L VISUALLY AND THEREFORE WE DIDN'T BOTHER TO IDENT THE ILS FREQ. ILS 21L STRUCTURE, THIS APCH REQUIRES THE PNF TO HAVE HIS NAV RADIO SET TO CARLETON VOR FOR INTXN DME INSTEAD OF DXO (DTW) VOR AS A RESULT YOU REALLY DON'T HAVE A GOOD REF OF WHERE THE ARPT IS DURING THE APCH.
