Should I use CTCSS or DCS?
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.
Can you use CTCSS and DCS at the same time?
The TX and RX codes will have to be the same unless you have a repeater to translate it (bharvey2’s suggestion requires a repeater to translate the DPL into PL etc). You can only use one method of tone squelch (DPL or PL) at a time.
What does DCS mean on a walkie talkie?
Digital Code Squelch
CDCSS or Digital Code Squelch (DCS) is a further development of the continuous tone-coded squelch system or CTCSS that uses a slow-speed, binary data stream passed as sub-audible data along with the transmission. Motorola calls this Digital Private Line or DPL. DCS is a two way, 3-digit, digitally encoded code.
What is a DCS channel?
DCS (Digital Coded Squelch) is digital data or code word that is transmitted with the voice audio. This data is sub-audible with most of it’s energy below 300Hz. However is does have a wide bandwidth from 2 to 300 Hz. Each code word is unique and all code words may be used on the same channel without interference.
What is CTCSS?
CTCSS is used to access repeaters and networks, allows multiple users to communicate on the same frequency (channel) without receiving radio traffic from each other, and is employed to improve radio operation in high RF noise, interference and congested areas.
Is CTCSS secure?
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 two-way radio communications channel. The CTCSS feature also does not offer any security.
What are CTCSS channels?
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 two-way radio communications channel.
How do I set up CTCSS?
How to manually program a simplex channel
- Press [VFO/MR] and enter Frequency Mode.
- Press [A/B] and choose the A Side (upper display).
- Press [BAND] for the frequency band.
- Disable TDR (Dual Watch/Dual Standby).
- Enter the frequency.
- optional – Enter the transmit CTCSS/DCS code.
- Assign the frequency to a channel.

Continuous Tone Coded Squelch System
In conventional radio, one of the most used and sometimes misunderstood features is CTCSS, which stands for Continuous Tone Coded Squelch System.
What does CTCSS DCS Dec mean?
CTCSS (Continuous Tone Coded Squelch Systems) aka “Tone Access” or “PL” CTCSS 1.01 – the very basics (Jim, KC9HI) Many repeaters have a LOCK on their receiver to keep unwanted interference from getting in (Lock = receive CTCSS tone). If it does, your radio needs to transmit the matching KEY to enter.
What is CTSS and DCS?
CTCSS (Continuous Tone Coded Squelch System) uses continuous tones below 300 Hz whereas DCS (Digital-Coded System) uses digital data or encoded-words which are very unique and all encoded words can be used on the same channel without interference.
What is the difference between CTCSS and DCS?
CTCSS and DCS are systems used to ignore other users who you may be sharing a radio channel with. These two systems are also referred to by other names, including CDCSS, PL and DPL, but the official terms are CTCSS and DCS. They both have the same function and work in similar ways. CTCSS stands for Continuous Tone Coded Squelch System.
What does CTCSS stand for on a radio?
CTCSS stands for Continuous Tone Coded Squelch System. Basically what it does is this: it adds a tone into your transmission at a certain frequency. Other radios must have the same CTCSS tone or code set to hear the transmission. It will also be heard if the radio has CTCSS and DCS off.
Can a radio with no CTCSS and DCS work?
If someone has a radio with no CTCSS and DCS on, they will be able to hear everyone on the channel/frequency, including people using CTCSS and DCS. CTCSS and DCS do not make additional channels. If someone is on the same channel with a different code, then it’s not a different channel.
What does DCS stand for on a radio?
It stands for Digitally Coded Squelch. It sends a number repeatedly encoded in digital as you speak, in the low frequencies so you do not hear it. If someone else transmits on the channel with a different or no DCS, the radio will not unmute.
