2011-08-16 · I was out flying my ultralight airplane the other day and I noticed something very strange. I always use a walkie talkie to communicate with people on the ground since there is no need for an aviation radio (not required where I fly), and I always set the pair to channel 21 privacy code 31 (CTCSS). As much as I understand, when you use a privacy code, you cannot hear other people that would be

DCS (aka DSQ/DPL) provides a slightly larger range of codes to pick from compared to CTCSS. This means less chance that a nearby station will accidentally overlap with yours. Specifically, DCS gives you 83 codes, whereas CTCSS gives you somewhere between 26-50 squelch tones depending on the radio -- manufacturers have added extra codes over time.

Motorolas " privacy codes" are a form of CTCSS tone codes. Try entering channel 1 on FRS frequency into a modern scanner. Talk on channel 1 and change only the privacy code. You will notice too the tone code as well will change for each privacy code. So, yes there is a tone code format for FRS. CTCSS takes advantage of the unused bandwidth below 300Hz by mixing one of the many tones listed below into the audio. If the radio receiver chooses to, it can keep the radio squelch circuit silent unless a particular tone is found. Features and Functions Below are some of the major features and functions of the UV-82 portable radio: Dual-band handheld transceiver with display LCD DTMF encoding Commercial FM radio receiver Allows storage of up to 105 programmable DCS codes and 50 CTCSS privacy codes 2020-07-20 · CTCSS is analog (a selection of tones, generally between 67 Hz and 255 Hz) With 9 bits, DCS codes are always denoted in base 8 (octal) Continuous Tone Coded Squelch System (CTCSS) allows you to ignore (not hear) unwanted calls from other persons who are using the same frequency.

• 121 Privacy Codes. (38 CTCSS 2 Feb 2017 Are we 100% sure that BCA CTCSS (privacy) codes are the same ones that Motorola uses? To be 100% sure, a simple frequncy counter with 4 Nov 2019 Display illumination and programmable keyboard,CTCSS and DCS functions, Incorporates 105 codes DCS” and 50 privacy codes “CTCSS” Features. • 8 Channels. • 121 Privacy Codes.

In any event, CTCSS works well in separating user groups. How radio "privacy tones" or CTCSS tones work.

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.

No code means you will hear everything on that channel, with a code you will only hear traffic with a matching code. Not all repeaters use CTCSS, The WRAK968 repeaters are set up with DCS codes instead. To my knowledge it is user preference as to which code group they wish to use with no real advantage to ether side.

17 Dec 2012 This video explains the difference between Midland CTCSS and DCS privacy codes and Motorola Talkabout interference eliminator codes.

To my knowledge it is user preference as to which code group they wish to use with no real advantage to ether side. 2020-11-02 Privacy codes are based on the CTCSS or DCS codes capability of two-way radios. A receiving radio that has a privacy code set will not un-mute its speaker unless that code is sent along with a transmission.

- posted in Guest Forum: My Cobra CXT1095 offers both type of privacy codes. Aside for any general tips on using (pros & cons) privacy code, got a couple of questions: # Seems like one downside of using a privacy code would be if someone in range was trying, in a worst case, to broadcast a Mayday or a PanPan I wouldnt hear it. 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. Likewise, when transmitting using CTCSS or DCS, the receiving station must have a matching tone or code to hear your call.Be aware that other parties can still hear your calls if they set up their transceiver CTCSS, DCS, "PL tones", privacy codes What does it all mean for you and your radio? 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.
