Is higher or lower squelch better?
Setting the signal too low will allow any signal level to come into your scanner. Setting the squelch too high will block all but the strongest signals from coming into your scanner.

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.
How do you set up squelch?
Adjusting the squelch is relatively straightforward. You simply set your mic up (powered on) at the furthest distance (or worst case) you ever expect to use it and adjust the squelch at the receiver until it just gates off your mic. Then move it back up just a little for an extra margin of safety.
Does squelch affect range?
Since received signal strength decreases as transmission distance increases, higher squelch settings will decrease the operating range of the system. In this system the squelch control essentially determines the “quality” of signal (signal-to-noise ratio) required to unmute the receiver.
What does squelch on a police scanner mean?
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.
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.
Does squelch affect transmission?
Does Squelch Affect Transmission? No. Squelch only affects the signals that your VHF radio receives, not the transmissions that you send. When you make a transmission, your radio broadcasts the same signal, regardless of your squelch setting.
What is the squelch on a scanner for?
What does squelch mean on walkie talkies?
In radio terms, squelch is the process of muting a channel when there is nothing on it. Usually, when you are on an open channel with no signal, you will hear the constant hiss of white noise which can be annoying.
How do you adjust squelch and RF gain?
Some truckers turn the squelch on a CB radio all the way off, turn the RF gain on a CB radio all the way on, then dial back the RF gain control until almost all the noise disappears. That eliminates the choppy signals that a squelched radio produces, but it still allows the distant signals to come in.
How far will a scanner pick up?
Generally, expect the scanner to receive signals from a 25- to 50-mile radius from your location.
