Why does AM radio go further than FM?
When they reach the layer of atmosphere called the ionosphere, they may be reflected back to earth .
This reflection enables AM radio waves to be received at great distances from the antenna.
FM transmission have a broadcast waves ( 88-108 MHZ) are shorter than AM broadcast waves (540 – 1600 kHz) and do not go as far..

How far can a 50000 watt radio station reach?
For most AM radio stations, which are only licensed to use 5,000 watts of power or less, these radio stations are heard only within a 30 to 50 mile radius. The most powerful 50,000 watt AM radio stations can be heard within a hundred miles or further in the daytime.
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.
Why is AM radio reception so bad?
If the battery operated radio reception is good, interference could be caused by the mains power – check the power cord is well insulated. If both radios are affected, the problem is likely to be electrical interference to the antenna, caused by a nearby electrical appliance.
What causes poor AM radio reception?
The main problem affecting AM signals is electrical interference. … The FM signal travels in a straight line and loses strength when it can’t be broadcast straight to the antenna; for example, when blocked by buildings, hills, or large trucks. This causes increased hiss or fading and interruption in the FM signal.
How can I get radio stations from other countries?
The internet has made it quite easy to listen to thousands of radio stations from around the world, free of interference. If you know the radio station you’d like to listen to there is likely to be a stream available at their website. Alternatively you can use a website or app like TuneIn to browse stations by country.
How far away can you hear a radio station?
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 I tune into a local radio station?
To listen on your smartphone or tablet, you need to download the TuneIn mobile app. It’s available (for free) for iOS, Android, Windows Phone, and Blackberry devices. On your computer, you listen in by pointing your browser to http://www.tunein.com.
How far does radio travel?
The distance a radio wave travels in one second, in a vacuum, is 299,792,458 meters (983,571,056 ft) which is the wavelength of a 1 hertz radio signal. A 1 megahertz radio signal has a wavelength of 299.8 meters (984 ft).
How far can FM radio waves travel?
40 milesReception distance VHF Radio waves usually do not travel far beyond the visual horizon, so reception distances for FM stations are typically limited to 30–40 miles (48–64 km).
