A method for stopping on a radio station includes calculating a radio signal
quality
(205) using a multipath echo indicator and determining if the radio signal
quality is greater than a predetermined signal quality threshold (210).
A zero crossings indicator of a demodulated signal may be used (225) to
reduce a false alarm rate. An apparatus includes an antenna (105), a local
oscillator (110) coupled to the antenna, an analog-to-digital converter
circuit (115) coupled to the local oscillator, a demodulator circuit (120)
coupled to the analog-to-digital converter circuit, a signal strength determining
circuit (125) coupled to the analog-to-digital converter circuit, a logarithmic
circuit (150) coupled to the signal strength determining circuit, a multipath
echo bandpass filter (155) coupled to the logarithmic circuit, and a stop-on-station
circuit (145) coupled to the demodulator circuit, the multipath echo bandpass
filter, and the logarithmic circuit.
