What should I set my squelch to?
Ideally, the squelch level should be set just above the background radio noise level or at the point where the desired signal is becoming too noisy to be acceptable. Higher settings of squelch level require higher received signal strength to unmute the receiver.
What is squelch used for?
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 transmission.
What does squelch level mean?
The squelch setting adjusts the threshold at which signals will open (un-mute) the audio channel. It acts to suppress the audio output of the receiver in the absence of a sufficiently strong desired input signal. With the squelch level correctly set, you will hear sound only when actually receiving a signal.
