In telecommunications, Continuous Tone-Coded Squelch System or CTCSS is one type of in-band signaling that is used to reduce the annoyance of listening to other users on a shared …

Continuous Tone-Coded Squelch System (CTCSS) and Digital-Coded Squelch (DCS) are two technologies commonly used to achieve this goal. They allow operators to selectively mute …

CTCSS is a Continuous Tone Coded Squelch System. It does this by adding a low-frequency audio tone to the voice. Where more than one group of users is on the same radio frequency, …

CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digital Coded Squelch) are signaling systems employed in walkie-talkies to improve communication by minimizing …

What is CTCSS? CTCSS stands for Continuous Tone Coded Squelch System, often referred to as “PL” (Motorola’s trade name) or “Channel Guard” (Ericsson/GE’s trade name). Many …

Apr 16, 2025 · CTCSS, or Continuous Tone-Coded Squelch System, is a function on two-way radios that mutes certain transmissions to prevent multiple messages from coming in at once.

Apr 30, 2025 · By configuring a specific CTCSS or DCS code, your radio attaches a sub-audible tone to transmissions. Only radios with matching codes will unmute and play your audio, …

Some call it by the most correct name (probably) of Continuous Tone Coded Squelch System (CTCSS). All this CTCSS stuff really is is a tone that is sent along with your voice to the …

Modern two-way radios contain 38 CTCSS codes which stands for Continuous Tone Coded Squelch System. The system filters transmissions to permit communication only between …

In telecommunications, Continuous Tone-Coded Squelch System or CTCSS is one type of circuit that is used to reduce the annoyance of listening to other users on a shared two-way radio …
