Military radio systems Military radio systems In telecommunication, a combat-net radio (CNR) is a radio operating in a network that (a) provides a half-duplex circuit and (b) uses either a single radio frequency or a discrete set of radio frequencies when in a frequency hopping mode. ...more on Wikipedia about "Combat-net radio"
Communications security (COMSEC): Measures and controls taken to deny unauthorized persons information derived from telecommunications and ensure the authenticity of such telecommunications. Communications security includes cryptosecurity, transmission security, emission security, traffic-flow security. and physical security of COMSEC material. ...more on Wikipedia about "Communications security"
The AN/FLR-9 is a type of very large circular " Wullenweber" antenna array, built at many locations during the cold war to gather signals for western signals intelligence (SIGINT). The world-wide network, known collectively as "Iron Horse", could eavesdrop on HF communications from almost anywhere on the planet. ...more on Wikipedia about "FLR-9"
GBZ is the callsign of a British VLF transmitter, which transmits on 19.6 kHz from Anthorn (formerly Criggion) encoded signals to submarines. Although the signals of GBZ cannot be decoded by common means, its reception - if its signal is shown in form of spectrograms - is very interesting, because the signals of GBZ show figures looking like fishes, garlands and ornaments on the spectrograms. At certain times these signals are also transmitted as strong pulses, so-called superpulses, which can oversteer the amplifier of a PC soundcard at distances of a hundred kilometres away from transmission site. ...more on Wikipedia about "GBZ"

The Joint Tactical Information Distribution System (JTIDS) is an L-band TDMA network radio system used by the United States armed forces and their allies to support data communications needs, principally in the air and missile defense community. It provides high- jam-resistance, high-speed, crypto-secure computer-to-computer connectivity in support of every type of military platform from Air Force fighters to Navy submarines. ...more on Wikipedia about "Joint Tactical Information Distribution System"
The Joint Tactical Radio System (JTRS) is planned as the next-generation radio for use by the U.S. military in field operations for the second decade of the 21st century. JTRS a software-defined radio for voice and data that will be backwards compatible with a very large number of other military and civilian radio systems. It also includes Wideband Networking Software to implement full-featured mobile ad hoc networks. ...more on Wikipedia about "Joint Tactical Radio System"

Multi Rolle Radio (English: Multi Role Radio) is a portable radio set which supports high speed frequency hopping and of course state of the art encryption. It was ordered early 1993 and first put to operative use in mid 1995. It operates on standard military VHF frequences ranging 30-88mhz. ...more on Wikipedia about "Multi Rolle Radio"
AN/PRC-77 Radio Set is a manpack, portable VHF FM transceiver used to provide short-range, two-way radiotelephone voice communication. It can provide secure voice (X-mode) transmission with the TSEC/ KY-57. The radio consists of the RT-841 transceiver and minor components. In the Joint Electronics Type Designation System (JETDS), AN/PRC is short for Army/Navy Portable Radio Communication. ...more on Wikipedia about "PRC-77"
A secret broadcast is, simply put, a broadcast that is not for the consumption of the general public as a whole. The invention of the wireless was initially greeted as a boon by armies and navies. Units could now be coordinated by nearly instant communications. It soon became clear that radio was a two edged sword. An adversary could glean valuable and sometimes decisive intelligence from intercepted radio signals: ...more on Wikipedia about "Secret broadcast"
SINCGARS stands for "Single Channel Ground and Airborne Radio System." It provides U.S. and allied military commanders with a reliable, secure, easily maintained Combat Net Radio (CNR) that handles voice and data. Vehicle-mount, backpack, airborne, and now handheld form factors are available. ...more on Wikipedia about "SINCGARS"
TADKOM / TAktisk Digital KOMunikasjon (English: TADCOM / TActical Digital COMmunication) is a encrypted network used as a carrier for most of the communication for all four branches of the norwegian military. Most nodes operate on a speed of 2mbit and above. TADKOM is also used to carry signals such as Link-11, Link-11B, Link-16 and Link-22(Future). ...more on Wikipedia about "Tadkom" http://www.shortopedia.com Dreamteam. Military_radio_systems
