Emergency Position-indicating Radiobeacon Station
An Emergency Position-Indicating Radio Beacon (EPIRB) is a type of emergency locator beacon for commercial and recreational boats, a portable, battery-powered radio transmitter used in emergencies to locate boaters in distress and in need of immediate rescue. In the event of an emergency, such as a ship sinking or medical emergency onboard, the transmitter is activated and begins transmitting a continuous 406 MHz distress radio signal, which is used by search-and-rescue teams to quickly locate the emergency and render aid. The signal is detected by satellites operated by an international consortium of rescue services, COSPAS-SARSAT, which can detect emergency beacons anywhere on Earth transmitting on the distress frequency of 406 MHz. The satellites calculate the position or utilize the GPS coordinates of the beacon and quickly passes the information to the appropriate local first responder organization, which performs the search and rescue. As Search and Rescue approach the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NJFA
__NOTOC__ NATO Joint Civil/Military Frequency Agreement (NJFA) and is the universal NATO common civil/military treaty to regulate the military access to the radio frequency spectrum in the range of 14 kHz to 100 GHz in peacetime, during exercises, in times of crisis, and in military operations. This document has been the basis for the frequency utilisation in NATO-Europe since 1982. Nations and organisations, e.g. partnership for peace countries, are invited to participate as deemed to be necessary. The national representatives of the frequency sovereignty agree unanimous to changes of the NJFA, in line to decisions of World Radiocommunication Conferences, operational requirement of the armed forces, and technical developments. However, the provision of "Article 38 of the International Telecommunication Convention, Nairobi 1982" remains untouched.International Telecommunication Convention, Nairobi 1982; § 163, 1.

Radio Station
Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM ( amplitude modulation), FM radio stations transmit in FM (frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB (digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale).
