What is a PL tone?
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.
Is PL tone the same as CTCSS?
Member. CTCSS is often called tone or tone squelch or PL, which is a Motorola trademark, etc. These are used for repeater access in the US and the tones are not audible in your speaker when properly implemented.
What is the difference between DCS and CTCSS?
Why CTCSS is Different from DCS? 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.
What does DCS mean on a walkie talkie?
Digital Code Squelch
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 are PL codes?
PL = Private Line. CTCSS = Continues Tone Coded Squelch System. 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.
How do you hit a repeater?
4 Answers. The simple answer is to transmit on the repeater’s input frequency, saying something like ” < your callsign > testing” and listen for the repeater’s courtesy beep (assuming there is one) on its output. If you’ve heard the beep, then you’ve hit the repeater.
What is a Csq tone?
CSQ means there is no tone. So you can pick it up.
How do you know if you hit a repeater?
The simple answer is to transmit on the repeater’s input frequency, saying something like ” < your callsign > testing” and listen for the repeater’s courtesy beep (assuming there is one) on its output. If you’ve heard the beep, then you’ve hit the repeater.
What happens if you don’t put a PL tone on Your Radio?
If your radio is not sending the proper tone, the repeater will not open, and repeat the signal. If you key your radio to talk to someone or some repeater that is using PL tones, you must provide the exact PL tone they are expecting, or it won’t work.
Is there a standard tone number for PL?
There is no generic standard tone number assignment or code letter to go with a particular tone; however, below is a chart of the commonly accepted 50 tones used at this time. In addition to these standard PL tones, there are also “Color Dot” frequencies that can be accessed through business two-way radios.
What’s the difference between a QC and a PL tone?
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. Many repeaters require the use of a PL tone to access the repeater.
Why do I need a PL tone on my repeater?
Typically the purpose of these tones are to key up, or “open” a repeater so you can talk through it. When you use your radio and try to talk on the repeater, you must send along with your voice message, the proper sub-audible tone (PL) to open up the repeater.
