Applies to mobile radio receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals using:a)angle (Type G or F: phase/frequency) modulation, orb)double-sideband amplitude (Type A) modulation with full carrier, orc)single-sideband amplitude (Type H, J or R) modulation with full, reduced or suppressed carrier.Standardizes the definitions, conditions and the methods of measurement used to ascertain the performance of selective-calling receiver-decoders.
