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 ]

K.W. Electronics was a British manufacturer of amateur radio equipment founded in the mid-1950s by the late Rowley Shears G8KW. It was based in Dartford, Kent, and manufactured a wide range of high frequency band receivers, transmitters and accessory equipment. The company was taken over by DECCA and subsequently ceased production during the 1970s.
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 nominal "17 m" band actually covers 16.6–16.5 m. The nominal "15 m" band actually ranges from 14.28–13.98 m. By common sense, the "15 m" band ought to be called "14 m", but that name has been in longtime use for a shortwave broadcast band. 80 metres or 80 / 75 meters – 3 500–4 000 kHz – 85.65–74.95 m actual
The first ten transceivers Swan produced were serial numbered from 101-1 to 110-1, with the first nine being model SW-120 operating on 20 meters (14 MHz), and the tenth, 110-1, being the first SW-140, operating on 40 meters (7 MHz). The SW-175 then covered the 75 meter band (3.8 MHz).
