Why does my CB squeal?

Excessively high SWR may cause squealing (and also results in short range). Try running a ground wire to a screw on the side of the radio. If you are using a power microphone, try turning the gain down. Also try using the original microphone.

Why do radios squeal?

An RF squeal or growl has a much harsher sound as compared to an audio feedback. It is normally caused from the radios own signal re-entering the radio and effecting the mike amp circuit or the transmitter circuit.

How do I stop my CB radio from interference?

You could try wrapping your CB radio power wire in tin foil. You could try shielding your radio by using tin foil. You could also try moving your radio or redirecting your wiring. Try using a different radio to ensure that your radio isn't having issues.

Why is my CB not transmitting or receiving?

Make sure the CB radio's fuse is not blown and that it is seated correctly. Also check the in-line fuse for the CB radio's power cord- if it is burned out, your radio will not power on.

What channel should my CB radio be on?

You can only contact those in a 40- to 100-mile radius, depending on the antenna, radio, and atmospheric conditions. There are 40 channels, and Channel 19 is best to connect with others, though if you're interested in making small talk, move to a less used channel.

Should CB antenna be grounded?

Ground Your Antenna Mount

If you're using a standard CB antenna (i.e., anything except a no ground plane, or NGP, kit), you'll need to make sure your antenna mount is solidly grounded to the vehicle's chassis. A bad ground will result in an un-tunable antenna and sky-high SWR levels.

Why is my SWR so high?

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.

Do CB noise filters work?

This power line filter really works - BUT - you the noise you're eliminating needs to be coming through your power line for this filter to be effective. If you're getting unwanted engine noise in your CB, try removing the coax cable first. If you still hear the noise without your coax connected, this filter will work.

What is NB on a CB radio?

What is the NB/ANL switch for? The Noise Blanker and Automatic Noise Limiter are used to reduce the amount of unwanted static, or interference you can get from many sources. Specifically these functions are mostly used for unwanted ignition noise, power lines, inverters, etc.

What causes interference on radio?

Interference occurs when unwanted radio frequency signals disrupt the use of your television, radio or cordless telephone. Interference may prevent reception altogether, may cause only a temporary loss of a signal, or may affect the quality of the sound or picture produced by your equipment.

What does a radio jammer sound like?

It is usually some type of noise, such as stepped tones (bagpipes), random-keyed code, pulses, music (often distorted), erratically warbling tones, highly distorted speech, random noise (hiss), and recorded sounds.

How do you increase CB power?

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. Safe operation of your CB should be with an SWR of 2:1 or less. Most people would prefer to be 1.5:1 or less.

Does coax length affect SWR?

Coaxial Cable Length Does Not Change Antenna SWR.

How do I know if my CB antenna is bad?

What does Delta Tune do on a CB?

The delta tune is the CB name for a very similar function on amateur radios called RIT, or receive incremental tuner. The Delta Tune controls the frequency your radio's receiver is operating on.

What is the Dynamike knob for on a CB radio?

DYNAMIKE - This control amplifies your voice to make you sound louder. It is like a built-in power mike. Normally you would have this control turned all the way up. If you are using a power mike and you experience squealing or distortion, try turning down the Dynamike.

How far will a CB reach?

CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances.

Does CB antenna length matter?

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 big does a ground plane need to be for a CB antenna?

In this case, it's a multi-band antenna the customer is using (it can be used from 700 MHz – 2700 MHz) so the ground plane required could be anywhere from 4-64 square inches.
