2021-1-30 · Many radios just have one set of numbered privacy codes, and you have to magically know where it switches from CTCSS to DCS. This is how my Motorola MT351R works. 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. 2020-1-12 · 6 PL-DCS Transmit CTCSS - Receive DCS 7 DCS-PL Transmit DCS - Receive CTCSS 8 DCS-CSQ Transmit DCS - Receive CSQ 9 CSQ-DCS Transmit CSQ - Receive DCS 10 DCS-NN Transmit and receive the same DCS code with normal polarity 11 DCS-NR Transmit and receive the same DCS code with different tx/rx polarity 12 DCS-RR Transmit and receive the same DCS CTCSS DCS - Miklor.

Ctcss vs dcs

Before the concept of trunked radio user groups and push-to-talk (PTT) over cellular, many users purchased portable radios and shared airtime over a given RF channel, which usually was owned and licensed by a local radio shop. 2021-1-30 · Many radios just have one set of numbered privacy codes, and you have to magically know where it switches from CTCSS to DCS.

As such, CTCSS can be used with PM transmitters as well as true FM transmitters. DCS / DPL is normally applied to the r.f.

Funktioner. • 8 kanaler. • 121 privatkoder. (38 CTCSS-koder/83. DCS-koder). • Handsfree (VOX).

CTCSS typically decodes in about 250ms or less. When decoding DCS on very weak signals, the DCS decode threshold can be as much as 2 dB worse than CTCSS. CTCSS is an analog system. A later Digital-Coded Squelch (DCS) system was developed by Motorola under the trademarked name Digital Private Line (DPL). General Electric responded with the same system under the name of Digital Channel Guard (DCG).

DCS, Ja, 104 toner. Drivspänning, 13,8 VDC. Strömförbrukning, Max 10A. Storlek, 112 x 30 x 145 mm. (WxBxH utan knappar och kontakter). of 3124 channel combinations are available when the 22 channels are combined with the 142 privacy codes (38 CTCSS/104 DCS).

DCS (Digital-Coded Squelch) uses a 23-bit digital pattern to activate coded receivers. 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. CTCSS (Continuous Tone-Coded Squelch System) uses sub-audible (below 300 Hz, not necessarily inaudible) tones to activate coded receivers.

Built-in CTCSS and DCS Encoder/Decoder Circuits The FT-1900R includes both CTCSS and DCS Encoder/Decoder circuitry, with Reverse CTCSS Decoding also available, to mute your receiver when a particular tone is received (instead of opening your squelch). And you can encode CTCSS and decode DCS, or vice versa, too, if your application requires it. Scanning for CTCSS and DCS Tones/Codes * Not all repeaters requiring a CTCSS tone or DCS code for access will transmit one back. In that case, you would need to listen on the repeater's input frequency for a station accessing the repeater and identify the tone they are using. ** Due to firmware changes in the UV5R/UV82 over time, this procedure CTCSS and DCS Encode/Decode Built In For easy repeater access, or silent monitoring of busy channels, both CTCSS and DCS (Digital Code Squelch) Encoder/Decoder circuits are built in. CTCSS and DCS configuration data may be stored independently in each memory channel.
