Repeater or Direct Operation

Monitoring Features
Radio users who switch from analog to digital radios often assume that
the lack of static on a digital channel is an indication that the radio is
not working properly. This is not the case.
Digital technology quiets the transmission by removing the
"noise" from the signal and allowing only the clear voice or data
information to be heard.
Monitor a channel to ensure the channel is clear before transmitting.
