In radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band .
Read moreWhat frequency is short wave?
High Frequency Broadcasting (HF), also known as Shortwave Broadcasting, is a radio service licensed by the FCC to operate between 5,950 kHz and 26,100 kHz . This is an international broadcast service where transmissions are intended to be received by the general public in foreign countries.

Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting . The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band.
Read moreWhat is considered short wave?
There is no standard cut-off for the near-infrared range; therefore, the shortwave radiation range is also variously defined. It may be broadly defined to include all radiation with a wavelength of 0.1μm and 5.0μm or narrowly defined so as to include only radiation between 0.2μm and 3.0μm.
Read moreDoes anyone still use shortwave?
“Media Network” began in 1981 as a weekly shortwave program; in 2000 that show ended in favor of its current online presence. “Other regions vary from country to country,” said Sennitt. “Shortwave is still significant in much of Africa, South Asia and parts of Latin America .”
Read moreWhy do I need a shortwave radio?
Over the years, people have relied on shortwave radio for broadcasting voice and news to listeners over massive areas – even spanning continents. Other uses include over-the-horizon radar, two-way international communication, and diplomatic communication.
Read moreWhat is the difference between short wave and medium wave?
By one or more reflections between the earth and the ionosphere, a short-wave radio signal can be received at long distances from the transmitter. And medium wave or mediumwave (MW) is a part of the Medium frequency (MF) radio band used for AM broadcasting.
