Narrative:

ATC tower cleared mooney to land from 2 mi right base to runway 25R. I called tower to report a cessna passing immediately in front of my aircraft then turning base. Tower advised that he had tried to contact my aircraft 4 times to amend the clearance to land. Neither my passenger nor myself heard any such transmission. My radio worked perfectly both previous and subsequent to the event.
