Narrative:

Another small GA aircraft (possibly a grumman from radio traffic); passed above my starboard wing from my 4 o'clock to my 10 o'clock at a vertical separation I would guess at being less than 200 ft. From radio traffic; I believe the other pilot was not aware of my position before crossing almost directly above me. My speed was approximately 90 KTS and I had recently made my radio call at approximately 10 miles out. The other aircraft seemed to be traveling much faster than my aircraft.

Title: Light Sport Aircraft pilot reports an NMAC with a low wing aircraft at 3;100 FT near CCR. The other aircraft passed overhead from the 4 o'clock position and apparently did not see the reporter.
