The MSR918-D is a true-diversity FM receiver module for desktop or 19-inch/1U rack use in wireless-microphone systems. It provides 32 switchable frequencies (16+16) across two bands: VHF 150–250 MHz and UHF 470–880 MHz. The receiver features high sensitivity, sharp selectivity, reduced intermodulation, TX battery telemetry, and a digital pilot-carrier tone squelch. An optional ITC928 interface enables intercom/PTT functionality with supported transmitters.
