What is a DPL code?

What is a DPL code?

DPL = Digital Private Line. DCS = Digital Coded Squelch. PL / CTCSS or DPL / DCS refers to the several different types of sub-audible codes that can be transmitted on a channel frequency by a group of radios using that frequency.

What is PL and DPL?

PL Tone stands for Private Line Tone, DPL is Digital Private Line. It is a sub-frequency that filters out other radio user’s transmissions on the same frequency in the area. You can and should still “monitor” the frequency first before transmitting of the channel.

What does PL mean in ham radio?

Below is the terminology used by different commercial companies for CTCSS: PL is the Motorola Abbreviation for “Private Line”. QC is the RCA abbreviation for “Quiet Channel”. CG is the General Electric abbreviation for “Channel Guard”. CTCSS is often referred to as a “PL” tone by many users.

Is DPL the same as DCS?

DCS and DPL are the same thing.

How many DPL codes are there?

The bitstream consists of a repetitive 23-bit Golay codeword consisting of 12 data bits (of which three are fixed) followed by 11 CRC bits. In theory this means that there are 512 possible DPL codes.

What does CTCSS mean?

Continuous Tone Coded Squelch System
In conventional radio, one of the most used and sometimes misunderstood features is CTCSS, which stands for Continuous Tone Coded Squelch System.

What is tone pl?

Technically speaking, PL tones are sub-audible tones that are transmitted simultaneously with the speech portion of the transmission. It is these tones that prevent other people from receiving the transmission.

What is R DCS?

CDCSS or Digital Code Squelch (DCS) is a further development of the continuous tone-coded squelch system or CTCSS that uses a slow-speed, binary data stream passed as sub-audible data along with the transmission. Motorola calls this Digital Private Line or DPL. DCS is a two way, 3-digit, digitally encoded code.

What is a PL frequency?

What are the MURS frequencies?

MURS devices have been permitted since 2002 to operate using five VHF frequencies known by users as the VHF “colour dot” frequencies. These frequencies are 151.820 MHz , 151.880 MHz , 151.940 MHz , 154.570 MHz and 154.600 MHz . MURS are premitted to emit no more than 2 watts maximum transmitter output.

What is DCS tone?

What does pl and DPL mean on a radio?

In short, PL and DPL are squelch features that allows groups of people using the same frequency from annoying each other and hearing each other’s radio communications. It essentially mutes the other users if they are using a different PL/DPL tone or no tone at all.

What does 071 DPL for digital private line mean?

DPL = Digital Private Line. It’s like PL tones, but it’s a digital code that is sent instead of the sub-audible tone. It’s just another option. 071 is the digital code that is used. It doesn’t mean the audio signal is digital, just that the squelch code is a digital code that is sent out.

What is the DCS code on a DPL?

DCS is a digital squelch scheme which is sent by a transmitter to control the squelch opening of a receiver. DCS is designed to work in the “so called” sub-audible portion of the communications audio band below 300 Hz. DCS digital code values are actually Golay {23, 12} codes.

Can a PL code be used on a two way radio?

While many people think PL tones and codes provide some kind of two-way radio encryption, the truth is they do not provide any scrambling, encryption or security advantages.
