Like other land mobile systems, NXDN systems use the VHF and UHF frequency bands. It is also used as a niche mode in amateur radio . NXDN is implemented by Icom in their IDAS system [1] and by Kenwood as NEXEDGE; [2] both Kenwood and Icom now offer dual-standard equipment which supports the European dPMR standard.
Amateurs use a variety of voice, text, image, and data communications modes over radio. Generally new modes can be tested in the amateur radio service, although national regulations may require disclosure of a new mode to permit radio licensing authorities to monitor the transmissions.
Types of radio emissions. The International Telecommunication Union uses an internationally agreed system for classifying radio frequency signals. Each type of radio emission is classified according to its bandwidth, method of modulation, nature of the modulating signal, and type of information transmitted on the carrier signal.
The International Beacon Project ( IBP) is a worldwide network of radio propagation beacons. It consists of 18 continuous wave (CW) beacons operating on five designated frequencies in the high frequency band. [1] [2] The IBP beacons provide a means of assessing the prevailing ionospheric signal propagation characteristics to both amateur and ...

R-S-T system. For other uses, see RST (disambiguation). S-Meter (ICOM IC-732 HF Transceiver) The R-S-T system is used by amateur radio operators, shortwave listeners, and other radio hobbyists to exchange information about the quality of a radio signal being received. The code is a three digit number, with one digit each for conveying an ...
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. [1] The term "amateur" is used to specify "a duly authorized person interested in radioelectric ...
