The 20-meter or 14-MHz amateur radio band is a portion of the shortwave radio spectrum, comprising frequencies stretching from 14.000 MHz to 14.350 MHz. [1] The 20-meter band is widely considered among the best for long-distance communication ( DXing ), and is one of the most popular—and crowded—during contests . [ 2 ]
The list of frequency ranges is called a band allocation, which may be set by international agreements, and national regulations. The modes and types of allocations within each frequency band is called a bandplan; it may be determined by regulation, but most typically is set by agreements between amateur radio operators.
Shortwave bands are frequency allocations for use within the shortwave radio spectrum (the upper medium frequency [MF] band and all of the high frequency [HF] band). Radio waves in these frequency ranges can be used for very long distance (transcontinental) communication because they can reflect off layers of charged particles in the ionosphere and return to Earth beyond the horizon, a ...
As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...
The 27 MHz CB27/81 Bandplan is a list of the channel frequencies for FM CB radio in the United Kingdom. Unlike CB usage in the United States , and subsequently elsewhere in the world, the original UK 40 channels progress in order with 10 kHz spacing.
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz).Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication.

GB3RAL, which is located at the Rutherford Appleton Laboratory, transmits continuously on a number of low-band and mid-band VHF frequencies – 40050, 50050, 60050 and 70050 kHz – as well as 28215 kHz in the 10-meter amateur band.
