The Kenwood communications product range includes hand-portable and mobile terminals (including Intrinsically Safe and ATEX / IECEx hand-portables), repeaters, infrastructure and application ...
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.
Many MDC-1200 systems utilize the unit ID option. With each push-to-talk press, the radio sends a data burst identifying the sending radio. Unit IDs are decoded as unique hexadecimal four-digit numbers. Every radio would have a unique four-digit ID, (for example: 0423 or 5990 ).
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.
Amateur radio operator. NASA astronaut Col. Doug Wheelock, KF5BOC, Expedition 24 flight engineer, operates the NA1SS ham radio station in the Zvezda Service Module of the International Space Station. Equipment is a Kenwood TM-D700E transceiver.
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 ...
The 33-centimeter or 900 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio on a secondary basis. It ranges from 902 to 928 MHz and is unique to ITU Region 2 (Americas). It is primarily used for very local communications as opposed to bands lower in frequency.
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 ...
