Narrative:

Approaching leesburg, fl, uncontrolled airport from west. Saw only one aircraft lifting from runway to southeast. I entered right base turning to final noticed another aircraft on final 200 ft below. Climbed and turned left downwind. Using a commercial flight guide, had monitored CTAF 127.2 as published -- heard no calls. On taxi out noticed signage listed CTAF as 122.725. Upon return home flight guide revision was in mail which showed new frequency. Change of CTAF frequency had occurred before I received revision.
