SMA USING WRONG UNI FREQ MAKES GAR AS HE SIGHTS ACFT ON RWY DURING FINAL APCH.

Narrative

I WAS ON A VFR FLT BTWN ANGEL FIRE NM (AXX) TO NAVAJO DAM STATE PARK (1V0). WHILE ATTEMPTING TO LAND AT 1V0 I WAS SET UP FOR THE FINAL AFTER MAKING A L BASE TO FINAL TURN AND ASCERTAINING THAT THE SLIGHT WIND THAT WAS PRESENT WAS FROM THE SW. I BROADCAST MY POS ON BASE AND ON FINAL ON 122.8 WHICH IS WHAT I NOTED FROM THE STATE OF NM NAVIGATIONAL MAP. WHEN I WAS APPROX 400 FT ABOVE GND LEVEL AND 3/4 OF MI OUT I NOTED A PLANE ON THE RWY. I THEN EXECUTED A TURN TO THE R TO PARALLEL THE RWY AND MADE A GAR; AGAIN BROADCASTING MY POS AS I WENT AROUND TO MAKE A DOWNWIND BASE AND FINAL AGAIN. I LANDED WITHOUT EVENT NOTING THAT THE PREVIOUSLY NOTED PLANE WAS IN THE PARKING AREA OF THE FIELD. UPON EXITING THE PLANE I NOTED THAT THE PLT WAS WRITING DOWN MY N NUMBER. WHEN I ASKED WHAT THE PROB WAS I WAS TOLD BY THIS GENTLEMAN THAT I WAS NOT USING APPROPRIATE PROC AT AN UNCTLED FIELD. HE ALSO REMARKED THAT MY XPONDER MUST BE BROKEN AS HE DID NOT PICK IT UP ON HIS TCASII DEVICE UNTIL I WAS EVEN WITH HIS PLANE; HE THEN NOTED THAT I WAS 600; THEN 700; THEN 800 FT ABOVE HIM. HE WAS VERY VOCAL AND MAD AND I ACTUALLY FEARED FOR A MOMENT THAT HE MIGHT STRIKE ME. HE THEN LET ME KNOW THAT 122.9 WAS THE CORRECT FREQ FOR USE AT THIS FIELD. I LATER LOOKED AT THE SAME MAP I HAD USED ORIGINALLY AND FOUND THAT THE OTHER PLT WAS CORRECT 122.9 IS THE MULTICOM FREQ FOR 1V0. I AM SURE THAT I JUST MISTOOK THE 9 FOR AN 8. I BELIEVE IN THE FUTURE I WILL MONITOR BOTH FREQS WHEN GOING INTO AN UNCTLED FIELD ALSO POSSIBLY 122.7. MY ACFT IS CESSNA 210.
