A method for use in locating a mobile transmitter in an emergency situation comprises the steps of (a) upon determining that the emergency situation exists, monitoring a bandwidth of a reverse voice channel (RVC) signal transmitted by the mobile transmitter; (b) determining whether the bandwidth exceeds a predetermined threshold; (c) if the bandwidth exceeds the predetermined threshold, measuring the location of the mobile transmitter; and (d) if the bandwidth does not exceed the predetermined threshold, performing a predetermined action to increase the bandwidth and subsequently measuring the location of the mobile transmitter.
