    An Icom IC-R5 hand-held scanner A GMRS radio that also has scanning capabilities. A scanner (also referred to as a radio scanner) is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases.

    So long as an intelligible signal gets to a single receiver in the system, the repeated audio, or audio sent to the console speaker, would be intelligible. In this arrangement, receivers at remote sites are connected to the voting comparator by private telephone lines, a channel in a D4 channel bank on a DS1, or an analog microwave baseband ...

    en.wikipedia.org/wiki/Rake_receiver

    A rake receiver utilizes multiple correlators to separately detect the M strongest multipath components. Each correlator output may be quantized using several bits. Demodulation and bit decisions are then based on the weighted outputs of the M correlators, which provide a better estimate of the transmitted signal than is provided by a single c
