Chapter 11 Continuous Tone Coded Squelch System (Ctcss); Using Ctcss - Kenwood TM-G707 Instruction Manual

1
You may sometimes want to hear calls from only specific
2
persons. The Continuous Tone Coded Squelch System
3
(CTCSS) allows you to ignore (not hear) unwanted calls
from other persons who are using the same frequency.
4
Simply select the same CTCSS tone as selected by the
5
other persons in your group. A CTCSS tone is
subaudible and is selectable from among the
6
38 standard tone frequencies.
7
Note: CTCSS does not cause your conversation to be private. It only
8
relieves you of listening to unwanted conversations.
