What does the Squelch feature on a radio do?
In telecommunications, squelch is a circuit function that acts to suppress the audio (or video) output of a receiver in the absence of a sufficiently strong desired input signal.
Squelch is widely used in two-way radios to suppress the annoying sound of channel noise when the radio is not receiving a transmission..

What is Delta Tune on Cobra CB?
Your Citizens Band radio includes an array of controls for receiving, adjusting and listening to audio from other CB radio users. The radio’s delta tune knob, also known as the clarifier control, reduces the amount of static present on the radio when communicating with another person.
What is squelch on a CB?
The squelch (or silencer) is a control found on all CB radio transceivers. This function is used to reduce background noise when there is no communication. … The signal/noise ratio determines whether a signal is heard or not.
What is T back on a CB radio?
While there are a lot of names for this control, the talkback function is a useful tool for you to monitor your own transmissions. In radios that do not have talkback, you are unable to hear your voice through your speaker. … Talkback allows you to hear yourself, which tells you that your radio is probably transmitting.
Is a longer CB antenna better?
Choosing the Optimal CB Antenna Length Yes, taller/longer is better for range of distance when it comes to an antenna and the optimal antenna length is 1/4 wavelength. That translates to 102 inches (8.5 feet), too tall to be practical for most mobile applications.
How do you squelch on a CB radio?
The higher you turn the squelch, the stronger the incoming signal will have to be in order for you to hear it. This has no affect on the receive as indicated by the meter. Turn it higher (to the right) to only hear strong signals. Turn it down (to the left) to hear weaker signals as well.
What is S RF on a CB radio?
S-RF meter is a signal strenthg meter, on transmit it shows the strength of the outgoing signal, on recieve the strength of the incoming signal or the background noise if no incoming signal.
Should squelch be high or low?
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.
Can a CB radio be traced?
Not hard to do, since all you need is a CB. And yes, the FCC can track where a CB is transmitting from, Heck, they can even tell what kind it is etc. BUT, thats if you’re a real bad guy threatening The Prez, for instance, not some backyard dunce with a base station harrasing us poor truckers.
How do you adjust the RF gain on a CB radio?
First, start off by leaving your car turned-off (if the radio is mobile). Second, turn both the Squelch and the RF Gain all the way down (counter-clockwise). Third, turn the main volume almost all the way up. Forth, begin raising the Squelch very slowly and stop right when the radio gets silent.
What is MIC gain on a CB radio?
Your Mic Gain control, which is short for “microphone gain” is in essence, a level control for your modulated audio. Or a much easier explanation: the Mic Gain controls how loud you are to everyone else. It’s a volume control for your voice.
How do I increase the signal strength on my CB radio?
There are several procedures for ensuring maximum output.TUNE THE RADIO. A CB radio is only as good as the coax and antenna connected to it. … USE CB-SPECIFIC ANTENNAS. … ESTABLISH A GROUND PLANE. … CHECK THE VSWR. … ELIMINATE RESISTANCE.
What causes high SWR on CB?
One of the most common causes of high SWR readings is incorrectly connecting your SWR meter to your radio and antenna. When attached incorrectly, readings will be reported as being extremely high even if everything is installed perfectly.
Can SWR be too low?
An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. … If you have an antenna that’s say, three feet or less, and the SWR tunes great (less than 1.5) across all the channels than maybe your antennas feedline coax or the antenna coil is “lossy”.
