How To Stop Ham Radio Interference To Get Clear Sound

Using amateur ham radio, you want to get a crystal clear connection. But most of the time, a lot of noise is what you get.

That’s because there is too much interruption that causes the signal to get weak. That’s why knowing how to stop ham radio interference becomes crucial.

To avoid the noises and get a clear line to talk on, you need to learn first what might be the reason for such an issue. And then have to deal with them accordingly.

Let’s not talk anymore and get started with getting things on the right track.

How To Stop Interference In Ham Radio

How To Stop Ham Radio Interference

Closely listen to the noise on your radio; you might notice a difference in the noises. That’s because the interference source isn’t the same always, and depending on what’s causing it, the noise sounds a bit different.

Now, let’s see what can cause such a problem.

Power lines

The biggest culprit in intruding the signals and causing those irritating noise is the power lines.

These can create those buzzing noises, especially when the weather is terrible; you will encounter them more. And it can be for various reasons in the power line.

One primary reason is arcing in the electric line. Probably, inside the line, there is some crack, or the insulators got damaged. It happens most of the time when the neutral and ground wires are within contact with each other.

The other is the corona (not the one you’re thinking) discharge. When the electricity leaks out of the atmosphere, you get the buzzing sound.

If you feel like the power line is causing the problem, don’t just go and fix it. It is the job of the power company to handle the issue. Not to forget, it is against the law to try to manipulate the power line.

But how do you figure out the cause is the power line near your area. It isn’t that hard. Take a radio with AM mode in use. And start walking near the line. When you find too much noise near any part of the line, that’s where the issue is. You just locate it and let the power company know about it.

They will take care of the rest.

Equipment

Another reason for having interferences within your Ham radio communication is the industrial equipment used around it. The noise is quite similar to the one you get from the power lines.

But identifying isn’t that difficult as you will hear a pattern that makes the noise in a particular cycle.

Now, there is a lot of equipment around us that can cause this. You’ve got your vacuum cleaners, air conditioners, microwaves, and so on.

The best way to solve this issue is to don’t use them when trying to communicate using Ham.

Defective Electric

Like the equipment, other electric things that can create the problem.

Most of the time, heavy loads in electric switches can create such a rasping sound. Not only you’ve got to fix them right away to solve the Ham interruption. But for the safety of your home, you need to deal with them as they are often the reason for fire accidents in homes.

Controllers

Speed controllers and dimmers often cause interference with the Ham radio signals. And in your home or office, you might find many devices that use such a thing. Take the smart bulbs as an example. They use the dimmer to control the light setting. Using one right now might be the reason you’re getting those screeching sounds on the radio.

Vehicles

This is the most surprising one that many don’t know about. When you try to start a car engine, you will pick up a lot of noise on the signal during the ignition, which creates those buzzing sounds. The reason behind this is the same as the power line system. The coils in the ignition create the electric arcing that makes life hard for you on the radio.

Fences

To be exact, electric fences are the reason you’re getting issues with the signal. The popping noise you get after every 1-second or so is because the home fences create the arcing problem.

How to Find the Source?

Now, I know that there are many home appliances and things around you that can cause the issue. And identifying one from the other can be a real pain, you know where. The best way to deal with it is to go with your device near the sources to see where you’re getting those loud noises. It might take some time, but life would be much easier once you figure it out.

The best way to go about it is to turn off the circuit breakers in parts of the home one by one and go there to find the electric noises. That way, you can locate the problem source much faster.

If it is coming from any external source instead of inside your home. The idea is the same. Take any radio device and use the AM mode and walk toward a particular direction to figure out where it is coming from or not.

Not all problems are fixable; as you can imagine, you can turn your microwave off, not your neighbors. In that case, use better quality equipment like an antenna or other stuff to improve the signal for you.

Conclusion

Finding the source and how to stop the Ham radio interference is a task that requires a lot of patience and effort.

For those who are genuinely passionate, it might be a job they will do with much care. But you use the device for hobby for some fun on and off, you can always look for accessories that help the signal.

No matter what you do, knowing what can be producing the problem is always good, and you now know what might be causing it.
