The SNV-12 uses Digital Signal Processors to continuously monitor multiple remote receiver sites and select the receiver with the best signal quality. A typical application is an LMR system in which mobiles and portables can hear a repeater, but due to their lower transmit power, the repeater can’t hear them.
Remote receivers can be positioned in the communications dead spots, with audio from each receiver linked to the SNV-12 voter. It will select the best quality signal from all unsquelched remote receivers and forward this signal to the repeater for rebroadcast and/or monitor by a dispatcher, thus providing greater talk back range for the field radios.
The PTG-10 pilot tone generator is available for use with receivers that lack pilot tone capability.
