Bad AM radio reception suddenly???

Don't know about a potentially defective radio, but suggest you start by measuring the vehicle's battery voltage to make sure it is still at full power. Since the battery is now at least 4 years old (assuming it is original), it may be the initial sign that it will soon need replacement. I've seen this before with weak batteries, or a bad alternator that is not properly charging. Also suggest you make sure the radio connectors, especially the antenna signal and ground are clean and tight since a poor connection could give the symptoms you are seeing.

Did you install tint?

Could be sun spots ?

AM is very sensitive to bad grounds and lose connections at the antenna. First tighten the antenna where it attaches to the vehicle. Second, check the tightness of the wire connection to the antenna; third, check the tightness of the plug end into the radio. If that does not help a new antenna may be needed. In the old day there was an AM trim screw to match the impedance but I have not seen that in "modern" car radios.

Did you drive through a tunnel?

Just checking - the IQ of people listening to AM talk radio is known to be a relatively small number

That's not true overall - the proportion of Air America listeners is pretty small, so the average IQ still remains very high.

You must be an AM radio talk show host.

Oh - why yes - certainly you've heard of me.

Also not true. Of course, all I have is a 6 tube Philco radio in my 1940 Royal Coupe!

You must be referring to Air America listeners.
