Par contre les personnes qui sont sur la même fréquence que vous, pourrons vous entendre. À moins qu’elles utilisent aussi un code CTCSS. Toutes fois il y a aussi des radios qui propose le CTCSS en émission et réception. part two: find the ctcss codes, privacy codes, pl codes, or subchannels for your frs/gmrs radio Step One: Understand what frequencies are matched to your Channel Numbers in your FRS/GMRS radios Here is the page from my Motorola Talkabout FRS/GMRS radio instruction manual to show what frequencies the channels are on.

Instead of the squelch simply opening when the received signal A CTCSS tone is a Continuous Tone-Coded Squelch System, something brought over to the hobby from CTCSS stands for Continuous Tone Coded Squelch System. Interference-Elimination Codes, sometimes refer to Tone Squelch, TalkGroup or Privacy Code. It works like Key and Lock on Door. Walkie Talkie transmits sub-audible tone (Key) and opens the door (Lock) on Receiver. For example: Group A on Ch1 no CTCSS, Group B on Ch1 Code1, Group C on Ch1 Code38.

CTCSS is an analog system. A later Digital-Coded Squelch (DCS) system was developed by Motorola under the trademarked name Digital Private Line (DPL).

You can even use CTCSS tones and Digitally Coded Squelch (DCS) codes on the same channel. The CTCSS encode deviation level can be adjusted up and 

One of the downsides of privacy codes is that you could assume that since you do not hear any communication on your radio, the channel is not being used. When I went to work for the police department at San Diego State University in 1972, there were 19 different campuses in the California State University System.

Incorporates 105 codes “DCS” and 50 privacy codes “CTCSS” programmable. * Function “VOX” (voice operated transmission). * Alarm function. * Up to 128 

In CHIRP it is called Tone for transmit and TSQL for receive. • Split tones - Transmitting and receiving different CTCSS tones or DCS codes.

CTCSS Tone Code Listing The tones in white with a letter suffix are supposed to be the only tones in use on UK repeaters, and the letter code is given after the Morse ID when the repeater times out. If you can't read Morse, use a free application on an iPhone or Android device. Privacy code 38 is CTCSS with a 250.3 Hz tone, privacy code 39 is DCS using code 023. The MT351R has 121 privacy codes, 38 CTCSS tones, and 83 DCS codes. The DCS-based privacy codes have been implemented two different ways. Uniden, Motorola, and Backcountry Access just keep the privacy code numbers going, and switch from CTCSS to DCS at code 39.

For the best results, you should compare CTCSS frequency information from your third-party radio with the information in this table.. CTCSS (Continuous Tone-Coded Squelch System) continuously superimposes any one of about 50 low-pitch audio tones on the transmitted signal, ranging from 67 to 254 Hz. The original tone set was 10, then 32 tones, and has been expanded even further over the years.

6 Oct 2012 Since most FRS radios seem to have adopted a 1 - 38 sub-channel system we at last have a way to express what CTCSS tone we all wish to  25 Aug 2016 The FM deviation for DCS is similar to CTCSS, about 600 to 800 Hz.
