What is squelch sound?
To squelch means to make a wet, sucking sound, like the sound you make when you are walking on wet, muddy ground.
What does break squelch mean?
“Breaking squelch” is a common term used to indicate that a received signal has risen above the power threshold, and thus indicates a strong enough transmission is present.
What is 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.
What is squelch in VHF?
In telecommunications, squelch is a circuit function that acts to suppress the audio (or video) output of a receiver in the absence of a strong input signal. Squelch is used in two-way radios and VHF/UHF radio scanners to eliminate the sound of noise when the radio is not receiving a desired transmitter.
What is squelch on a scanner?
What is squelched mean?
1a : to fall or stamp on so as to crush. b(1) : to completely suppress : quell squelch resistance. (2) : silence squelched the protesters. 2 : to emit or move with a sucking sound.
What causes squelch?
If the signal level of the radio frequency is below a certain amount, the gate stays closed and nothing gets passed to the mixer channel. When the signal is strong enough, the signal is passed along. At this point, the squelch circuit is keeping background noise from being passed to your channel.
What is 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.
Which is better DCS or CTCSS?
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. The different between CTCSS and DCS.
What is squelch type?
Essentially, squelch is a specialized type of noise gate designed to suppress weak signals. Squelch is used in two-way radios and VHF/UHF radio scanners to eliminate the sound of noise when the radio is not receiving a desired transmitter.
