What does SW mean on a radio?
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 metres); above the medium frequency band (MF), to the bottom of the VHF band.
What is FM MW SW?
FM/MW/SW Portable Radio It features a durable design and a large, easy-to-use Tuning/Volume Knob. An 8-cm speaker and 800-mW Power Output deliver crisp, clear sound.
Is shortwave radio AM or FM?
It’s called shortwave because, quite literally, the waves emitted are short as opposed to long wave and medium wave, used by AM radio, and wideband VHF (very high frequency) used by FM radio. These short waves can travel thousands of miles across the globe, so shortwave radio is, by nature, international.
Is AM or FM Better?
With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static.
What is full form of FM radio?
The full form of FM is Frequency Modulation. FM is a method or technique of encoding details about a given analogue or digital signal by changing the frequency of the carrier wave according to the frequency of the modulating signal.
What is disadvantage of FM over AM?
Explanation: The disadvantage of FM over AM is that in frequency modulation large bandwidth is required. While, in case of advantages, FM is less prone to noise interference and has lower power consumption compared to AM. So it is only used in frequency modulation and not in amplitude modulation.
Does AM radio still exist?
Even though AM is the first and oldest, it’s still around in more forms than you might think. There are over 6,000 AM stations in the U.S. today. And they still have a huge audience of listeners, typically locals who seek out the latest weather, traffic, and news information. Most still listen in their cars or trucks.
Is AM radio the same as MW radio?
AM, which stands for Amplitude Modulation (AM) is the oldest radio broadcasting system in the UK. The term AM is commonly used to cover both Medium Wave (MW) and Long Wave (LW). All AM radio stations broadcast in mono. It only broadcasts Radio 4 on LW.
Why is shortwave better at night?
Certain radio stations, however, especially the short-wave and AM bands, can travel much farther. Short-wave can circle the globe, and AM stations transmit hundreds of miles at night. You can pick up some radio stations better at night because the reflection characteristics of the ionosphere are better at night.
What is the most powerful radio station?
XERF is the most powerful commercial radio station in North America and the third most powerful in the world. With its mammoth transmitter across the Rio Grande in Ciudad Acuna, Mexico, XERF can increase its signal up to five times the 50,000-watt limit allowed by the U.S. Federal Communications Commission.

How do I get good FM radio reception?
Get a new antenna. Switching from an indoor to an outdoor antenna can greatly improve FM reception. If you have a directional antenna, try switching to an omnidirectional antenna, or vice versa. Directional antennas can pick up stations from farther away, but omnidirectional antennas work well for closer stations.
