Narrative:

Violated base of sfo class B airspace in transition through sql and across bay by approximately 50-100 ft. VFR, squawking 1200 without assistance from ATC. Primary cause was flight of low time/familiarity in type. Also, around XA00 that same day, errantly squawked code from trk to C83 and from C83 to Q99, neglected to change to VFR on ground at C83.
