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.
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 USMC ordered 60,000 radios to be used until replaced by the more complex Joint Tactical Radio System (JTRS) cluster 5 spiral 2 radio in 2013. [2] However, JTRS was cancelled in October 2011, [3] and thus the PRC-153 continues to serve. The IISR is a Motorola XTS 2500i [4] with
The Motorola APCOR (Advanced Portable Coronary Observation Radio) was a 12 watt, paramedic telemetry radio produced by the Motorola company during the 1970s and 1980s. The Motorola APCOR could transmit voice and EKG simultaneously and was battery operated.
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] By July 1941, it was in mass ...
A walkie-talkie, more formally known as a handheld transceiver, HT, or handheld radio, is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald Hings, radio engineer Alfred J. Gross, Henryk Magnuski and engineering teams at Motorola. First used for infantry, similar ...
Motorola Type II refers to the second generation Motorola trunked radio systems that replaced fleets and subfleets with the concept of talkgroups and individual radio IDs. [1] [2] There are no dependencies on fleetmaps, therefore there are no limitations on how many radio IDs can participate on a talkgroup. This allows for greater flexibility ...
The ASTRO 25 core is the hub for the communications network. It comprises P25 portable and mobile radios, dispatch consoles, data applications, and RF conventional or trunked sites. [16] In addition to ASTRO 25, Motorola also builds several other P25 radio models, including the APX family of radios, designed for first responders. [17]
