All digit zeros are shown in the tables with a slash through them,
to eliminate the chance of confusing them with the capital letter O.


CTCSS (Continuous Tone-Coded Squelch System) uses sub-audible (below 300 Hz, not necessarily inaudible) tones to activate coded receivers. PL (Private Line) is Motorola's trademarked name for this system. General Electric calls theirs CG (Channel Guard).

DCS (Digital-Coded Squelch) uses a 23-bit digital pattern to activate coded receivers. DPL (Digital Private Line) is Motorola's trademarked name for this system. General Electric calls theirs DCG (Digital Channel Guard).
