Narrative:

Upon reaching the toll plaza at the san mateo bridge, we made visual contact of san carlos airport and requested a frequency change. Bay approach approved our request. At this point we reported 10 mi out at the toll plaza and requested field advisories on the CTAF for san carlos 119.0 and received negative response. We proceeded to make the same request from mid span san mateo bridge and heard, 'winds calm and use the runway of your choice.' and moments later we recognized the voice of airport one, as he complimented the virtues of the v-tail bonanza. We then reported on a right 45 degree entry to the downwind leg of runway 30, there appeared to be no other aircraft in the pattern. We then reported turning right base for runway 30 and in turn reported 1 mi final. We received a transmission that 2 aircraft appeared to be converging. We looked around and saw nothing, due to the fact that no other radio calls were made from another aircraft, no visual contact was made, considering his earlier remarks, the tone of his voice which had no urgency. We thought that he was being facetious. We landed the airplane, reported clear of the active runway, received a transmission that there would be an incident report, at which time we noticed an airplane on final. We taxied to our tie-down and still heard no radio call. An airplane then landed. Saratoga one told us that the radios in small aircraft Y were functional, but he did not hear them make any radio calls either. Key facts: 1) the saratoga did not make any radio calls. 2) the saratoga did not make a standard entry into the pattern. 3) we made the proper entry to the pattern and called out our position in accordance with the rules and regulations.
