A data communication receiver (100) includes a first antenna feed (106) coupled to a first receiver element (110) for demodulating (502) a radio signal containing data bits and for deriving a first phase-locked loop error signal. The data communication receiver (100) also includes a second antenna feed (108) coupled to a second receiver element (112) for demodulating (502) the radio signal and for deriving a second phase-locked loop error signal. A received signal strength indicator (134, 144) measures signal strength of the radio signal from the first antenna feed (106) during reception of a data bit, and concurrently measures signal strength from the second antenna feed (108). A processor (146) then defines (506, 508, 512) the data bit as received from the antenna feed (106, 108) having the greater signal strength to be the optimum data bit.
