A radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that two-way radio signals can cover longer distances. A repeater sited at a high elevation can allow two mobile stations, otherwise out of line-of-sight propagation range of each other, to communicate. [ 1 ]
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]
The lowest series has adjacent tones that are roughly in the harmonic ratio of 2 0.05 to 1 (≈1.035265), while the other two series have adjacent tones roughly in the ratio of 10 0.015 to 1 (≈1.035142). An example technical description can be found in a Philips technical information sheet about their CTCSS products.

Motorola radios with MDC options have an option allowing the radio to filter out data bursts from the ...
In 1990, the T800 series of modular base station and repeater equipment was on the market. The T700 series also appeared. [8] In 1992, the T2000 series of mobile radios was released. [8] In 1993, additional offshore subsidiaries were opened and the T3000 series of hand-portables and the Quasi-Sync base station/repeater systems were introduced. [8]
The introduction of Motorola Type II SmartZone introduced the IntelliRepeater. An IntelliRepeater, or IR, site is a bare-bones trunked site which has no database of users or talkgroups . It is simply sophisticated software running on a Quantar repeater.
