What is CTCSS encode and decode?

What is a CTCSS (PL) Tone? A CTCSS is a ‘Tone’ sent along with your voice when you transmit. The transmit tone is referred to as the Encode tone. The receive tone is referred to as the Decode tone.

What is CTCSS decode?

CTCSS is a system whereby a (not really) sub-audible tone is encoded into the transmit audio of a radio and a receiver on another radio on that frequency will only open up (decode) when it picks up that specific tone. Higher frequency tones are more easily heard.

What is a CTCSS DCS code?

CTCSS codes are functions that reject undesired signals on your channel. You will hear a call only when you receive a signal that contains a matching CTCSS tone or DCS code. If a call containing a different tone or code is received, squelch will not open and you will not hear the call.

How do Ctcss codes work?

Radio transmitters using CTCSS always transmit their own tone code whenever the transmit button is pressed. The tone is transmitted at a low level simultaneously with the voice. This is called CTCSS encoding. CTCSS tones range from 67 to 257 Hz.

Should I use Ctcss or DCS?

DCS stands for Digitally Coded Squelch. Digital subtone (DCS) has 104 subtones. Compared to CTCSS toneS, the code speed is faster, the bit error rate is lower, and much users in the same channel. DCS is newer than CTCSS, and has more codes.

How many Ctcss codes are there?

Most two-way radios have 38 CTCSS codes which stands for Continuous Tone Coded Squelch System. Many two-way radio manufacturers have different names for this feature. These are some of the manufacturers and their names: Motorola: “Private Line (PL),” GE/Ericsson: “Channel Guard”, E.F.

Should I use CTCSS or DCS?

Is Ctcss or DCS better?

Which is better DCS or CTCSS?

Compared to CTCSS toneS, the code speed is faster, the bit error rate is lower, and much users in the same channel. DCS is newer than CTCSS, and has more codes. This gives a lower chance of picking the same code as someone else. The different between CTCSS and DCS.

What is PTT ID code?

PTT ID, or Push-To-Talk ID, is a generic term for an automatic number identification (ANI)-like system used in two-way radio systems. It provides identification of the transmitting radio over the air, and is commonly used in selective calling/signaling systems, usually in commercial and public safety radio systems.
