about 100 milesUseful daytime AM service is generally limited to a radius of no more than about 100 miles (162 km), even for the most powerful stations. However, during nighttime hours the AM signals can travel over hundreds of miles by reflection from the ionosphere, a phenomenon called “skywave” propagation.
How do number stations work?
At their most basic, numbers stations are simply shortwave radio transmitters, generally operating between 3,000 and 30,000 kilohertz. They’re located in many, many countries, but no one knows just how numerous they are. They often transmit strings of numbers or numbers intoned by a computerized-sounding voice.
Does AM or FM travel further?
FM radio waves also travel horizontally and skyward. However , due to the higher frequency of the carrier waves, the waves that go skyward are not reflected. They pass through the atmosphere and into space. Although AM waves can be received at greater distances than FM waves , FM.
