Narrative:

Departure had been properly briefed, however neither pilot idented the acd NDB nor did we notice the ADF switches in the 'ant' position. We turned left at the vjz 261 degree radial and then began chasing the 'dead' ADF needles. As we turned too far south, I realized that the needles were not giving proper information, so I asked the PNF to get a heading to acd. He then became occupied in updating the FMS, direct to acd, but was delayed in the procedure doing so. Departure then called asking us why we were not proceeding to acd, which we explained. He cleared us direct to zmr, and advised that we had set off a noise monitor. Supplemental information from acn 372679: navigation error resulting in noise violation. ADF's were tuned. At the hold short position for runway 36 the needles were selected from VOR to ADF and pointed toward the beacon used on this SID (off the left wing). When I tuned the ADF's I failed to detect that the small ADF-ant toggle switches were in the ant position. In this situation the ADF needles point to the left 90 degrees. This SID calls for runway heading till crossing a VOR radial approximately 2 mi from runway, then a turn to the left toward a beacon 6 mi to the wnw. I was setting climb power and handling the radios with the aircraft in a left turn when the first officer asked for a further adjustment left of the heading bug. At this point I should have discovered something was wrong, but in a hurry to get the power set I moved the bug on to the left toward the ADF needles. When the first officer commented about their bearing I realized something was wrong. We leveled the wings and I asked the controller to proceed direct to the next position. He cleared us but informed us of the violation. We had turned well inside the beacon. This was the first time I had made this mistake. I will never tune ADF's again without thinking of this switch position.

Title: WDB ACR FLC ATTEMPTS TO FOLLOW THEIR ADF INDICATORS FOR THE DEP PROC BUT END UP S OF THE DESIRED POS. THE ADF SELECTORS WERE IN THE ANTENNA POS. THEY WERE CHASING 'DEAD' NEEDLES. DEP CTLR ADVISED THEM OF A NOISE VIOLATION.

Narrative: DEP HAD BEEN PROPERLY BRIEFED, HOWEVER NEITHER PLT IDENTED THE ACD NDB NOR DID WE NOTICE THE ADF SWITCHES IN THE 'ANT' POS. WE TURNED L AT THE VJZ 261 DEG RADIAL AND THEN BEGAN CHASING THE 'DEAD' ADF NEEDLES. AS WE TURNED TOO FAR S, I REALIZED THAT THE NEEDLES WERE NOT GIVING PROPER INFO, SO I ASKED THE PNF TO GET A HEADING TO ACD. HE THEN BECAME OCCUPIED IN UPDATING THE FMS, DIRECT TO ACD, BUT WAS DELAYED IN THE PROC DOING SO. DEP THEN CALLED ASKING US WHY WE WERE NOT PROCEEDING TO ACD, WHICH WE EXPLAINED. HE CLRED US DIRECT TO ZMR, AND ADVISED THAT WE HAD SET OFF A NOISE MONITOR. SUPPLEMENTAL INFO FROM ACN 372679: NAV ERROR RESULTING IN NOISE VIOLATION. ADF'S WERE TUNED. AT THE HOLD SHORT POS FOR RWY 36 THE NEEDLES WERE SELECTED FROM VOR TO ADF AND POINTED TOWARD THE BEACON USED ON THIS SID (OFF THE L WING). WHEN I TUNED THE ADF'S I FAILED TO DETECT THAT THE SMALL ADF-ANT TOGGLE SWITCHES WERE IN THE ANT POS. IN THIS SIT THE ADF NEEDLES POINT TO THE L 90 DEGS. THIS SID CALLS FOR RWY HEADING TILL XING A VOR RADIAL APPROX 2 MI FROM RWY, THEN A TURN TO THE L TOWARD A BEACON 6 MI TO THE WNW. I WAS SETTING CLB PWR AND HANDLING THE RADIOS WITH THE ACFT IN A L TURN WHEN THE FO ASKED FOR A FURTHER ADJUSTMENT L OF THE HEADING BUG. AT THIS POINT I SHOULD HAVE DISCOVERED SOMETHING WAS WRONG, BUT IN A HURRY TO GET THE PWR SET I MOVED THE BUG ON TO THE L TOWARD THE ADF NEEDLES. WHEN THE FO COMMENTED ABOUT THEIR BEARING I REALIZED SOMETHING WAS WRONG. WE LEVELED THE WINGS AND I ASKED THE CTLR TO PROCEED DIRECT TO THE NEXT POS. HE CLRED US BUT INFORMED US OF THE VIOLATION. WE HAD TURNED WELL INSIDE THE BEACON. THIS WAS THE FIRST TIME I HAD MADE THIS MISTAKE. I WILL NEVER TUNE ADF'S AGAIN WITHOUT THINKING OF THIS SWITCH POS.

Widebody transport air carrier flight crew attempts to follow their ADF indicators for the departure procedure but end up south of the desired position. The ADF selectors were in the antenna position. They were chasing 'dead' needles. Departure controller advised them of a noise violation.
