What should I listen to on shortwave?
Specialized interests of shortwave listeners may include listening for shortwave utility, or “ute”, transmissions such as shipping, sailing, naval, aviation, or military signals, listening for intelligence signals (numbers stations), or tuning in amateur radio stations.
What is the difference between shortwave and longwave radio?
The frequency for longwave range from 30KHz to 279 KHz , covering a median wavelength of 150 meters. On the other hand, the frequency of shortwave varies between 1.5 MHz to 30 MHz which covers around 10 to 85 meters. Longwave moves along the ground at a certain power and moves across in a linear line.

Shortwave (SW) radio operates on the frequencies between the AM and FM bands. Shortwave has the unique characteristic of traveling very long distances making it a powerful medium to reach the masses from even one transmitter.
How far can a shortwave radio reach?
Shortwave radio travels much farther than broadcast FM (88–108 MHz). Shortwave broadcasts can be easily transmitted over a distance of several thousands of kilometers, including from one continent to another.
Can you talk on shortwave radio?

What does shortwave mean?
1 : a radio wave having a wavelength between 10 and 100 meters. 2 : a radio transmitter or receiver using shortwaves. 3 : electromagnetic radiation having a wavelength equal to or less than that of visible light.
What is LW frequency?
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. … In contemporary usage, the term longwave is not defined precisely, and its intended meaning varies.
Can shortwave radio be jammed?
Because radio propagation on shortwave can be difficult to predict reliably, listeners sometimes found that there were days/times when the jamming was particularly ineffective because radio fading (due to atmospheric conditions) was affecting the jamming signals but favouring the broadcasts (a phenomenon sometimes …
Is FM radio going away?
The BBC has cancelled plans to switch off FM radio broadcasts and force millions of listeners to tune into digital transmissions. The corporation is set to announce FM will remain as part of a ‘hybrid’ future that will operate alongside DAB and the internet.
