/LOS transceiver with embedded communications security (COMSEC). The LST-5E provides the user with a single unit for high-grade half-duplex secure voice and data over both wideband (25 kHz) AM/FM and narrowband (5 kHz) 1200 bits per second (bps) binary phase shift keying (BPSK) and 2400 bps BPSK. Current applications for the LST-5E include manpack, vehicular, airborne, shipborne, remote, and fixed stations. The terminal is compatible with other AM or FM radios that operate in the 225-399.995 MHz frequency band [8]. AN/PRC-6725 or Leprechaun A handheld or wearable tactical radio. It can be programmed from a frequency fill device, laptop or PC, system base station, or it can be cloned from another radio [9]. MBITR (MultiBand Intra/Inter Team Radio) Provides voice communications between infantry soldiers. The Land Warrior Squad Radio is a SINCGARS-compatible, eight-channel radio. MBITR is a software capable design based on the commercially available PRC-6745 Leprechaun radio [10]. CSEL (Combat Survivor/Evader Locator) Provides UHF communications and location for the purposes of Joint Search and Rescue Center operations. CSEL uses GPS receivers for geolocation. Two-way, OTH, secure beaconing through communication satellites allows rescue forces to locate, authenticate, and communicate with survivors/evaders from anywhere in the world. The handheld receivers are one segment of the CSEL command-and-control system. The satellite-relay base station, Joint Search and Rescue Center software suite, and radio set adapter units interface with the UHF SATCOM network to provide CSEL capability. Upgrades through software loads make CSEL radios software capable [11]. MIDS (Multifunction Information Distribution System) A direct-sequence spread-spectrum, frequency-hopping, anti-jam radio that supports the Link 16 protocol for communication between aircraft. Operates in the band around 1 GHz. Originally called Joint Tactical Information Distribution System (JTIDS), this radio waveform has been redeveloped on a new hardware platform
