The AN/PRC-153 is the Joint Electronics Type Designation System designation for the US military version of the Motorola XTS-2500i secure handheld 2-way radio, known as the Integrated, Intra-Squad Radio (IISR) within the US Marine Corps. [1] Its intended purpose is squad-level communications during urban warfare.
The SCR-536 is often considered the first of modern hand-held, self-contained, "handie talkie" transceivers (two-way radios). It was developed in 1940 by a team led by Don Mitchell, chief engineer for Galvin Manufacturing (now Motorola Solutions) and was the first true hand-held unit to see widespread use. [1]
MDC (Motorola Data Communications), also known as Stat-Alert, MDC-1200 and MDC-600, is a Motorola two-way radio low-speed data system using audio frequency shift keying, (AFSK). MDC-600 uses a 600 baud data rate. MDC-1200 uses a 1,200 baud data rate. Systems employ either one of the two baud rates.
This requires either two separate radio channels or channel sharing methods such as time-division duplex (TDD) to carry the two directions of the conversation simultaneously on a single radio frequency. [2] The first two-way radio was an AM-only device introduced by the Galvin Manufacturing Corporation in 1940 for use by the police and military ...
Motorola first introduced digital two-way radio in the U.S. in 1991 under the name ASTRO Digital Solutions. [1] With the completion of the APCO Project 25 standard, Motorola introduced the ASTRO 25 solution and migrated its ASTRO Digital Solutions customers to ASTRO 25. Project 25 (also known as P25) is a suite of digital radio communications ...
Motorola SCR-300 circa 1940. The SCR-300, designated AN/VRC-3 under the Joint Electronics Type Designation System, was a portable frequency modulated (FM) radio transceiver used by US Signal Corps in World War II. This backpack-mounted unit was the first radio to be nicknamed a "walkie talkie". [1]
The AN/PRC-6809 MBITR Clear is a variant of the MBITR, made available without encryption. While the PRC-148 includes US Type 1 capabilities in all versions, the PRC-6809 uses Level III Data Encryption Standard, making it available to police, firefighters, and militaries unable to obtain International Traffic in Arms Regulations (ITAR) approval.
The ARC-210 is a family of radios for military aircraft that provides two-way, multi-mode voice and data communications over a 30 to 512+ MHz frequency range. It covers both Ultra High Frequency (UHF) and Very High Frequency (VHF) bands with AM , FM and SATCOM capabilities. [ 1 ]
