This is an example of Digital and Analog cross mode
operation. The IDAS radio (including repeater) can
receive both analog mode and digital mode signals on
a single channel. This function is useful when
introducing digital system components into an existing
analog system. It allows the system operator to
communicate with analog only terminals while utilizing
the digital features as required.
