Product ID: SLR 8000
The MOTOTRBO™ SLR 8000 is a high-power 100 W base station repeater engineered for continuous 100% duty cycle operation across demanding dispatch and trunked networks. Housed in a space-saving 2U rackmount chassis with no thermal ventilation gap required above or below, it features a high-sensitivity receiver, built-in 5 A battery charger, integrated front-panel speaker, and comprehensive connectivity (including Ethernet, USB, DB25, and external frequency reference input). Supports DMR digital protocols (Tier II and Tier III) as well as conventional and trunked analog systems (including MPT 1327).
Product features:
100% continuous duty cycle operation at full RF output power up to 100 W 
Compact 2U rackmount form factor with zero spacing required above or below 
Built-in 5 A battery charger with automatic AC to battery revert function 
Integrated front speaker, volume control, and microphone jack for local operation and servicing 
Internal diagnostic circuitry tracking voltage, current, power output, temperature, and VSWR 
Flexible internal options including preselector, antenna relay, and wireline card (4-wire audio/tone control) • Product description
The Motorola SLR 8000 represents the pinnacle of reliability for professional base station repeaters. Validated through Motorola's Accelerated Life Testing (ALT) program, it guarantees stable 100 W continuous transmit output under harsh operational conditions. Its next-generation receiver with high sensitivity and superior noise blocking excels at congested RF sites, delivering clear voice communications and error-free data transmission.
The SLR 8000 serves as the core infrastructure for high-density, mission-critical radio networks. Ideal for sectors including:
Critical Infrastructure & Utilities: power utilities, mining operations, pipeline networks
Public Safety & Defense: emergency operations centers, security agencies, site defense
Transportation & Logistics Hubs: seaports, international airports, railway corridors
Industrial Manufacturing: heavy manufacturing facilities, chemical plants, refineries
