Narrative:

Routine VFR charter from napa county airport to salinas. In a C182 that is LORAN equipped. Leveled at 3500 ft to follow highway 680 southward around the sfo class B airspace. About 5 mi southwest of the concord airport, the alert light goes off indicating that I am in class B airspace. I doublechked on my VFR terminal area chart (which was current) and verified with ground chkpoints that I was in the proper area. I had briones reservoir to my right and walnut creek in front of me so I figured it was a malfunction of the LORAN. I got on flight following about over dublin and stayed with it the rest of the way into salinas. What raised a question in my mind was every controller asked me to read back my call sign twice and verify my squawk code. I do not speak with an accent and they said my radios were loud and clear when asked, so it made me think that perhaps a violation of the airspace had occurred. I am very sure of my position, but I know that the FAA is enforcing possible problems stronger and stronger so I want to make sure my record stays clear by filing the proper paperwork with you at NASA.
