CTCSS (Continuous Tone-Coded Squelch System) Codes. * Some radios use 69.4 Hz instead, which better fits the harmonic sequence, and this tone is often omitted as a choice. 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.

CTCSS (Continuous Tone-Coded Squelch System) uses sub-audible (below 300 Hz, not necessarily inaudible) tones to activate coded receivers. PL (Private Line) is Motorola's trademarked name for this system. General Electric calls theirs CG (Channel Guard). DCS (Digital-Coded Squelch) uses a 23-bit digital pattern to activate coded receivers. Btw, "privacy codes" on FRS radios are just CTCSS codes.

• The icon appears on the display when the DCS function is ON. • Each press of [TONE] changes the selection as follows: Tone (T) –> CTCSS … So those cheap two-way FRS/GMRS radios use the same 2m UHF bands and use CTCSS for the “privacy” code… which amusingly isn’t private as anyone tuned to the same frequency can hear the transmission. For example, a FRS radio on channel 4-2 is using simplex frequency of 462.6375MHz and a CTSCSS of 71.9Hz. 14-4 would be 467.7125MHz and 77.0Hz. With CTCSS it may seem like you have your own private channel but other parties can still hear your calls if they set up their radio with the same tone code or no tone code at all.

CTCSS (Continuous Tone-Coded Squelch System of Continuous Tone Coded Subaudio Squelch) is een systeem van ruisonderdrukking bij radioverbindingen. Dit systeem maakt het mogelijk een radiokanaal met meerdere gebruikers te delen, en minimale storing van elkaar te ondervinden. CTCSS frequencies and squelch codes may differ in some radios from third-party manufacturers. For the best results, you should compare CTCSS frequency information from your third-party radio with the information in this table. CTCSS does not offer any “privacy”, it only filters which transmissions a CB will “un-squelch” for, but everybody in non-CTCSS land can still hear you, whether you want them to or not. CTCSS is a limited aid in sharing channels but the FM capture effect still applies, and the more “powerful” station (either by RF output or proximity) will still win at the end of the day.

CTCSS 38ch Standard Frequency Table Some FRS radio literature calls these CTCSS tones “privacy codes,” though there is no encryption employed and conversations over these radios are overheard simply by pressing the monitor button. In any event, CTCSS works well in separating user groups.

Often these will be called "privacy codes" or " subchannels" on FRS radios. Set both CTCS-R (receiving code) and CTCS-T ( transmitting DTMF encoding. • Commercial FM radio receiver.

Radios Explained: "Privacy codes" are the opposite of privacy, CTCSS & DCS. Watch later.

2020-11-02 · To solve that, privacy codes like CTCSS and DCS got introduced. What they do is that they set a system in place where specific codes get sent to a receiver to accept the signal. The receiver got that code already set in their device. If you aren’t transmitting using the same channel and code, it won’t get received. The receiver will be quiet.
