Hi,

Two of the most common problems related to poor AM reception are radio noise interference, and weak AM reception.

When dealing with a radio noise and interference problem it is common to notice that your radio gets noise on AM but not on FM. Car stereos are particularly susceptible to radio interference on AM. This is because AM transmits on a very low frequency compared to FM and the AM frequency is much more susceptible to interference from the cars electrical components.

If you hear a high-pitched whining noise that changes when you step on the gas, the noise is most likely coming from the alternator, distributor or sparkplugs. Audio interference problems can also be caused by your vehicle's fuel pump.

If the radio noise problem originates in the car's electrical system, you should have your electrical connections inspected, especially the grounds, and you may have to install a noise filter on your radio.

Alternator noise is ab audible whine where the pitch varies with engine speed, roughly from about 1,000-HZ and higher. This type of noise is conveyed by the power supply connections. It can be reduced by use of a filter in the power leads between the radio and the battery. These filters can be purchased at places like RadioShack and are easy to install.

The other main source of interference comes from the vehicles ignition system. The source of most ignition noise is from the spark plug sparking itself. If your spark plugs do not contain ignition noise suppressors, the noise will radiate from the spark plug wires, too. The first step in reducing this noise is to use spark plugs which contain radio frequency suppressors.

Spark plugs intended to suppress radio frequency interference (RFI) are generally made in two styles, resistive and inductive. Resistive plugs contain a small series resistance in the plug body to suppress RFI. The resistance also affects the spark slightly, tending to reduce it. Inductive plugs have a small coil or inductor in the plug body which is more effective at suppressing RFI. Inductive plugs do not affect the spark as much. You might want to enquire about fitting a set of these sparkplugs with your mechanic or at AutoZone if you decide to do it yourself.

Some car antennas are embedded in the rear window or within the roof of the car – AM reception in these cars tends to be very poor and there is not much you can do about it. However if your car has an external antenna you may be able to improve the AM quality by grounding the shield of the antenna plug behind the radio.

This is just a matter of removing the radio, wrapping a bit of wire around the outside of the AM/FM antenna plug, and fastening the other end of the wire to the metal support structure in the dash.

As you can see - suppressing noise on AM reception involves quite a few steps in a car that is not adequately suppressed by the manufacturer. However provided you follow these steps and if AM reception is important to you then you should be able to resolve the issue through a few simple steps on your part.

Hope this helps and thanks for using FixYa.

There may be a lot of interference that's why you have a poor am signal. This is a common problem on all car radio when it comes to am unlike the fm that has good signal even on low areas. Well I guess that this is something that we should live with.
