Narrative:

I was flying south toward sus, spotted aircraft a mi or two ahead, appeared to be wbound, well above me. Looked down to fiddle with VOR, looked up and aircraft, a silver C120 or C140, passed above (slightly) and to right, heading in more or less opposite direction as me. Distance may not have qualified for near miss, but was uncomfortably close for me. Visibility excellent, and I had spotted the traffic. But I apparently misjudged its altitude and direction, and did not give it the priority it deserved until it was well distant. VOR tuning at that moment was unnecessary. I don't know if pilot in other aircraft saw me, I saw no evasive action.

Title: A GA PLT HAS AN NMAC WITH ANOTHER IN VFR CONDITIONS. THE RPTR WAS HEAD-DOWN ADJUSTING HIS NAV FREQ.

Narrative: I WAS FLYING S TOWARD SUS, SPOTTED ACFT A MI OR TWO AHEAD, APPEARED TO BE WBOUND, WELL ABOVE ME. LOOKED DOWN TO FIDDLE WITH VOR, LOOKED UP AND ACFT, A SILVER C120 OR C140, PASSED ABOVE (SLIGHTLY) AND TO R, HEADING IN MORE OR LESS OPPOSITE DIRECTION AS ME. DISTANCE MAY NOT HAVE QUALIFIED FOR NEAR MISS, BUT WAS UNCOMFORTABLY CLOSE FOR ME. VISIBILITY EXCELLENT, AND I HAD SPOTTED THE TFC. BUT I APPARENTLY MISJUDGED ITS ALT AND DIRECTION, AND DID NOT GIVE IT THE PRIORITY IT DESERVED UNTIL IT WAS WELL DISTANT. VOR TUNING AT THAT MOMENT WAS UNNECESSARY. I DON'T KNOW IF PLT IN OTHER ACFT SAW ME, I SAW NO EVASIVE ACTION.
