system can be used on all channels, but both systems cannot be used on the
same channel at the same time.
To successfully communicate using a privacy code, both the sending and
receiving radios must be tuned to the same channel and to the same privacy
code system (CTCSS or DCS) and privacy code number. Each channel will remember
the last privacy code system and number you select.
The privacy code 00 is not a privacy code, but allows all signals to be heard
