NON TWR ARPT USING WRONG CTAF MADE APCH AND LNDG OPPOSITE TO LNDG TFC. NO CONFLICT.

Narrative

I WAS INSTRUCTING A STUDENT ON A FLT FROM WLW. WE TRIED OPENING OUR FLT PLAN ON 122.3 AND COULD NOT GET SACRAMENTO APCH TO ANSWER. WE DSNDED BELOW THE BEALE AFB ARSA AND TRIED TO CONTACT MARYSVILLE ON 123.0. GETTING NO RESPONSE; WE ASSUMED OUR RADIO WAS INOP. WE CIRCLED THE ARPT AND AT 1400 FT MSL; STAYING BELOW AND OUT OF THE BEALE AFB ARSA; WE CHKED THE WIND SOCK ON THE ARPT AND DISCOVERED THE WIND FAVORED RWY 32. WE MADE A L DOWNWIND TO RWY 32 AND MADE A NORMAL APCH. ON FINAL I NOTICED AN AIRPLANE ON THE RWY BUT HE CLRED THE RWY AND WAS ON THE TAXIWAY WHEN WE WERE ON A 1 MI FINAL. WE LANDED NORMALLY; PARKED AND TALKED TO FSS ON THE FIELD. WE WERE INFORMED THE CTAF WAS 119.3 AND CONFIRMED IT WITH OUR VFR SECTIONAL CHART. MY CURRENT PLT'S GUIDE TO CAL ARPTS WAS STOLEN THE NIGHT BEFORE AND I WAS USING ONE THAT WAS OUT OF DATE; THUS MY USE OF 123.0. I APOLOGIZED TO FSS AND OFFERED TO APOLOGIZE TO THE PLT OF THE OTHER AIRPLANE. 5 MINS AFTER WE LANDED FSS CHANGED THE LNDG RWY TO RWY 32; CONFIRMING OUR CORRECT INTERPRETATION OF THE WINDS FAVORING RWY 32. THERE WAS NO DANGER OF COLLISION; HOWEVER; I REGRET NOT CONSULTING MY CURRENT SECTIONAL AS IT WOULD HAVE GIVEN ME THE CORRECT 119.3 FREQ. WHEN WE TOOK OFF; WE HEADED TOWARD TRAVIS AND STRAYED BELOW BEALE AFB ARSA. THE REMAINDER OF THE FLT PROGRESSED NORMALLY.
