Amateur radio operators take part in portable operations using radio equipment when traveling. "Portable" equipment indicates a configuration that allows for relatively rapid collection, transportation, and deployment of amateur radio gear. A portable station can be anything from a small QRP (Low Power) radio and antenna, to a large transceiver.
The 15-meter band (also called the 21-MHz band or 15 meters) is an amateur radio frequency band spanning the shortwave spectrum from 21 to 21.45 MHz. The band is suitable for amateur long-distance communications, and such use is permitted in nearly all countries.
[24] [25] [26] Introduced in the year 2000, the radio was known for its "all-in-one" functionality. It can transmit on all amateur radio bands between 160 meters and 70 centimeters, with the exception of the 1.25 meters band, and the "X" model also has built-in 23 centimeters band capability option. Kenwood discontinued production of the TS ...
In the days of crystal-controlled radios, these pairs were identified by the last portion of the transmit (Input) frequency followed by the last portion of the receive (Output) frequency that the ham would put into the radio. Thus "three-four nine-four" (34/94) meant that hams would transmit on 146.34 MHz and listen on 146.94 MHz (while the ...
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 ]
VOACAP simulation of propagation against distance, comparing effective radiations of 1 watt (top) and 99 Watts (bottom).. The practice of operating with low power was popularized as early as 1924, with a variety of reports, editorials and articles published in U.S. amateur radio magazines and journals that encouraged amateurs to lower power output, both for purposes of experimentation, and for ...
