Narrative:

We listened to AWOS. About 10 NM out; it was clear below 12000 ft and visibility was 10 mi; wind 280 degrees at 9 KTS. I told the student that the CTAF was 122.8 and he changed frequencys. I failed to notice he set the frequency to 120.8. He reported our position and intentions at 5 mi; 2 mi south and crossing midfield; downwind; left base; and final. After landing and during rollout; we noticed the commuter on about a 1/2 mi final. We had landed on runway 35 and the commuter was landing runway 17. I felt we might not have time to go to the next taxiway to clear the runway and a go around would put us in a perilous position; so we taxied off to the runway onto the smooth grass on the east side of the runway and were well clear of the runway when the commuter taxied by. This incident could have been avoided had I been more observant of the frequency on the radio. It was an oversight and hopefully will not happen again.

Title: STUDENT AND INSTRUCTOR PLTS HAVE CONFLICT WITH COMMUTER ACFT LNDG OPPOSITE DIRECTION AT NON-TOWERED ARPT. DISCOVER THEY HAD TRANSMITTED POSITION REPORTS ON WRONG CTAF FREQ.

Narrative: WE LISTENED TO AWOS. ABOUT 10 NM OUT; IT WAS CLR BELOW 12000 FT AND VISIBILITY WAS 10 MI; WIND 280 DEGS AT 9 KTS. I TOLD THE STUDENT THAT THE CTAF WAS 122.8 AND HE CHANGED FREQS. I FAILED TO NOTICE HE SET THE FREQ TO 120.8. HE RPTED OUR POS AND INTENTIONS AT 5 MI; 2 MI S AND XING MIDFIELD; DOWNWIND; L BASE; AND FINAL. AFTER LNDG AND DURING ROLLOUT; WE NOTICED THE COMMUTER ON ABOUT A 1/2 MI FINAL. WE HAD LANDED ON RWY 35 AND THE COMMUTER WAS LNDG RWY 17. I FELT WE MIGHT NOT HAVE TIME TO GO TO THE NEXT TXWY TO CLR THE RWY AND A GAR WOULD PUT US IN A PERILOUS POS; SO WE TAXIED OFF TO THE RWY ONTO THE SMOOTH GRASS ON THE E SIDE OF THE RWY AND WERE WELL CLR OF THE RWY WHEN THE COMMUTER TAXIED BY. THIS INCIDENT COULD HAVE BEEN AVOIDED HAD I BEEN MORE OBSERVANT OF THE FREQ ON THE RADIO. IT WAS AN OVERSIGHT AND HOPEFULLY WILL NOT HAPPEN AGAIN.
