Overview
The Digi-Wave system is a digital spread-spectrum (DSS), simultaneous two-way wireless listening system.

The Digi-Wave communication system allows users to listen and talk to one another wirelessly in a variety of scenarios

A Digi-Wave system consists of at least one transceiver (DLT 400) and various combinations of transceivers and receivers (DLR 400 RCH or DLR 400 ALK).
