Abstract: A method and apparatus in a data communication receiver (100) for diversity reception of a radio signal including a predictably repetitive, predetermined data bit pattern (304) comprises a processor (114) controlling (600) an antenna switch (106) to select between a first antenna feed (102) and a second antenna feed (104) as a momentary source of the radio signal during transmissions of the predetermined data bit pattern (304). The radio signal received from the momentary source is monitored by a data receiver (110) during the transmission of the predetermined bit pattern (304) to derive the data therefrom, and at least one bit error count is determined (604, 610) by the processor (114). After completion of the predetermined bit pattern (304), an antenna feed (102, 104) for the radio signal is selected (616, 620) in response to the at least one bit error count.
