When using two-way radios or walkie-talkies, we all use CTCSS/DCS or Motorola system PL tones or DPL.  It is divided into CTCSS and DCS. Both CTCSS and DCS are all used on analog two way radios. Do you know what is the difference between CTCSS and DCS?   ...

CTCSS (Continuous Audio Coded Squelch System) is the most commonly used. Digital Code Squelch is a further development of the continuous tone-coded squelch system. In order not to accidentally turn on the transmitter by the clutter signal, the repeater must set the receiving CTCSS tone. To connect the repeater, the intercom must be set to CTCSS tone.  ...

CTCSS and CDS are also referred to by other names, including CDCSS, P, and DPL, but the official terms are CTCSS and DCS. They don't stop anyone from listening to you, they just stop you from hearing other people.  ...

As we all known, many analog repeaters have their own frequency and CTCSS Tone, and the frequency maybe always the one many people already remembered, but not the CTCSS/DCS tone. So now, if your radio can scan for a CTCSS/DCS tone, that will be very useful. Today, let us see the CTCSS/DCS scanning on Retevis RT85.   ...

the privacy tones are CTCSS tones, DCS tones, or PL tones, or Squelch tones. But, it should be understood that the privacy codes, as such, do not ensure the privacy of your conversation.  ...

When use on ham radio, for example, sometimes we know the repeater frequency, but dont know what is the CTCSS/DCS. At this time, it is very helpful if your radio has the CTCSS/DCS scan function.  ...

CTCSS/DCS scan is a very useful feature for a radio amateur, Retevis RT5R as a ham radio, although there is no CTCSS/DCS menu, but it also can scan the CTCSS/DCS.   ...
