What Do You Need to Improve AM Radio Reception at Home
For improving AM radio reception, there is some important information you need to know beforehand.
Why Does the AM Radio Reception Become Worse
Before improving AM radio reception, you need to detect what kind of interference is causing the biggest problems for you.
The buzzing sound results from electrical interference. It seems like an appliance is close to where you place the radio.
To eliminate the sound, you need to turn off the appliance or move it to another location. Relocating the radio can also help.
If the radio creates a hissing noise, it’s most likely due to a poor signal. This case can happen if you’re too far away from a transmitter or if there are huge objects between the radio and the signal channel.
You may need to purchase an antenna or move the radio nearer to the window to cope with this problem.
The “shhh” sound occurs when a signal travels to the receiver via multiple paths.
The most common causes of this sound are cross-interference among the signals reflecting off towering buildings and direct transmissions.
If this resembles your problem, you should consider adding an antenna on your rooftop.
When your house is close to the transmitter, this sort of interference happens. In this circumstance, the radio signal has become overwhelmed.
You need to use an attenuator, which you’d plug in between the serial port and the antenna. That’s all you should do.
Antenna is crucial
Changing the antenna is a certain method to improve your AM reception. What you must be certain of is how much money you are ready to pay. Some antennas cost lots of money while other models can be extremely inexpensive.
Before you buy the external antenna, remember to check the radio to see if it includes an AM antenna port or not.
If yes, find a wire approximately a foot long and connect it to the AM port. This technique enhances AM reception.
If the said technique doesn’t work, consider investing in an AM radio antenna booster. The loop model might also be a viable option. It is a regular radio antenna that has been bent into a loop. It can collect radio signals more effectively because of its structure.
We suggest orienting the loop antenna in a position that allows it to roll towards the station for the greatest results.

5 Tips to Improve AM Radio Reception at Home
There are some methods to boost AM radio signal. They appear to be simple to follow. Let’s have a closer look at them.
Tip 1: Remove some domestic appliances
You should inspect the placement of your radio at home. There is some household equipment that affects the AM reception. They are microwaves, televisions, or smartphone chargers.
Keeping the radio away from these items is the best solution. Then, set it somewhere where it won’t get obstructed in its signal transmission.
A mobile radio can help you quickly determine if your household appliances are interfering with radio reception or not. To test this, place your radio close to a microwave oven. Listen and see whether the buzzing sound gets louder as you approach it.
If this isn’t the case, you can experiment with various appliances until you find the one that causes the most interference. You are free to move the radio away from that device.
This technique, though, does not work for some appliances you may have at home. It’s unhelpful for things that must always function, such as smoke alarms or automated yard lights.
But don’t worry! We still have some other tips.
Tip 2: Adjust the antenna
You should note down that the extended telescopic antenna on the radio is suitable for FM radio channels. The one that takes up AM signals is often inside the radio. It often stays at the back of the device.
Due to the antenna’s directional construction, it collects signals from certain directions far better than others.
As a result, you need to know the direction of the transmitting station first. Then, point the back of your radio that way to improve AM reception.
Tip 3: Change the location
Placing your radio near the window will get better AM reception. However, this approach will certainly cause some interference if there are power lines nearby. In such a situation, you need to move the radio a little further from the window.
When the sound seems fine, where you’re standing is the best placement for your radio.
Tip 4: Adjust the radio settings
You may also re-adjust the equalization settings on your radio, as long as it has one. Tuning up the bass and lowering the treble can assist you.
Resetting should help to eliminate a lot of the distortion, particularly if you’re listening to a conversation like talk shows.
However, it limits the dynamic range of the device. So this method can be a very extreme action to take.
Tip 5: Purchase a new radio
The last option is buying a new device to enhance your listening enjoyment. The new model allows you to pick up AM signals effortlessly. Satellite and shortwave radios are two of the most popular examples.
Long-distance transmissions can be possible in shortwave radio. Meanwhile, a satellite radio gets signals from a specific satellite around the earth, which is superior to regular radios. The AM radio station, however, needs to be broadcast to a satellite to function effectively in this case.
What If the Tips Above Don’t Work
In certain cases, your AM radio reception quality fails to increase although you apply the tips given. There are some underlying issues you should consider.
Your favorite AM station may lack the necessary power to broadcast a powerful signal in your region. At this point, the best you can do is invest in a more powerful antenna.
A large number of stations really target a specific geographical location for their broadcasts. They often focus the signal on the regions with the most residents.
In certain cases, stations will even modify their direction at night in order to save power or vary their broadcasting frequency.
The transmitters of some radio stations are frequently away from their source. It might be confusing, particularly if the station continues to promote its existence in your area.
They use this idea to give the impression that they have a broader distribution network and establish themselves as a station with obvious control over their frequencies. Yet, in fact, they don’t.
The above article is the step-by-step instructions for how to improve AM radio reception at home. Following the tips assists you in upgrading the signal detection of your AM radio. As a result, you can boost your radio sound’s quality and enhance your experience.
