Why does my radio have so much static?
Radio static can be caused by antenna noise
If the noise is present only on the radio, then it’s most likely coming through your antenna lead. Unplug the antenna. If the noise goes away, try an antenna noise suppressor (like American International’s AS100).
Why is there static in my car Bluetooth?

How do you fix static in speakers?
You can usually fix this by getting a power bar with power filtration built in or by picking up a separate power line filter and plugging your power bar into it. There’s also the possibility the speaker noise comes from radio signals picked up by unshielded speaker wires or the speaker itself.

Why is AM radio so bad?
AM transmissions are much more susceptible than FM or digital signals are to interference, and often have lower audio fidelity. Thus, AM broadcasters tend to specialise in spoken-word formats, such as talk radio, all news and sports, leaving the broadcasting of music mainly to FM and digital stations.
How do you fix radio interference?
There are three basic methods of reducing RFI. The first is to prevent the radio interference from reaching the antenna by shielding. If the noise source is totally enclosed in a metal can, then the noise is contained and cannot reach the antenna.
How do you detect radio interference?
Detecting interference typically involves using a spectrum analyzer. Today, suppliers offer both swept-tuned and real-time spectrum analyzers (RTSAs). While a traditional swept-tuned spectrum analyzer can be used for interference detection, it does have certain limitations when compared with an RTSA.
Why does touching a radio antenna reduce static?
The signal quality increases because your body is an antenna. You increase the radio antenna length and hence it’s “gain” when you touch it. This effect doesn’t happen at all frequencies and the increase in gain is fairly small. It can make a difference if the signal you are trying to listen to is weak.
