Human Factors; Procedure
On approach to OAK Runway 11; [we] planned visual approach due to ATIS of 2;600 FT ceiling and 10 miles [visibility]. I briefed the ILS course; frequency; and touchdown zone elevation. I somehow failed to set the correct ILS frequency on my side First Officer had the correct frequency on his side. Weather was worse than planned. We were being vectored for the ILS to Runway 11. Somewhere near ALCAT we were cleared for the approach. The aircraft flew past the LOC course due to the frequency error. We were vectored back toward the course but again failed to intercept. ATC canceled our approach clearance and gave us a heading toward the field with a climb to 3;000 FT. Approaching 2;500 FT they called traffic out above us and gave us urgent instruction to descend to 1;800 FT. We complied and saw the traffic on TCAS (no RA occurred). After we crossed the field at 1;800 FT; we were given a climb and RADAR vectors to an uneventful ILS to Runway 11.
OAK Air Carrier arrival for Runway 11 selected an incorrect localizer frequency resulting in a failed intercept requiring additional ATC vectors and an eventual go around event.
