Should I use DCS or CTCSS?
Digital subtone (DCS) has 104 subtones. Compared to CTCSS toneS, the code speed is faster, the bit error rate is lower, and much users in the same channel. DCS is newer than CTCSS, and has more codes. This gives a lower chance of picking the same code as someone else.
What is the difference between CTCSS and 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.
Can you use CTCSS and DCS at the same time?
The TX and RX codes will have to be the same unless you have a repeater to translate it (bharvey2’s suggestion requires a repeater to translate the DPL into PL etc). You can only use one method of tone squelch (DPL or PL) at a time.
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.
Is CTCSS secure?
The CTCSS feature also does not offer any security. A receiver with just a carrier or noise squelch does not suppress any sufficiently strong signal; in CTCSS mode it unmutes only when the signal also carries the correct sub-audible audio tone.
What is the difference between CTCSS and tone?
Simply Tone is encode only and CTCSS is encode and decode. DCS is always encode and decode.
What are CTCSS channels?
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.
What is a CTCSS DCS code?
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.
What is CTCSS stand for?
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 a DCS table?
DCS is also known as Motorola Digital Private Line – “DPL “ DCS is a digital form of CTCSS. Instead of sending a continuous audio tone however, it transmits a low level digital signal. DCS sends a fixed octal digit 4 as the first digit, followed by the three octal digits shown in the table.
What is the purpose of CTCSS?
CTCSS is used to access repeaters and networks, allows multiple users to communicate on the same frequency (channel) without receiving radio traffic from each other, and is employed to improve radio operation in high RF noise, interference and congested areas.
Where is the CTCSS unit on a Kenwood tr-9000?
Hi/Low button and repeater offset knob (K, T, X models) My TR-9000 is fitted with a ZS6MRK tone board at 88.5Hz. CTCSS signal is injected at the junction of L1 and C16 on the TX unit, just before the modulation pot. The actual CTCSS unit is fitted on the other side of the radio, close to the speaker.
What kind of filter does a Kenwood tr-9000 have?
TR-9000(JP) have very selective front-end with 2-pole bandpass filter->FET amplifier->3-pole high quality bandpass filter. TR-9000G(JP) have same block diagramm of front-end, but bandpass filters are more simple and looks the same as TR-7700(another VHF FM RIG on Japanese market, well known in EU/US as TR-7730 with “split” feature).
Is the Kenwood tr-9000 a VHF transceiver?

Is the Kenwood tr-9000 2m SSB mobile good?
Recently purchased one from a friend, as i wanted a dedicated 2M SSB mobile, the reviews of the Kenwood were certainly good so i took the leap and got it. First impressions, built like a tank, good full received audio, the transmitted audio is full and apparently nice to the ear. Received signals are clear, even weak “back of the box” are clear.
