The reliability and serviceability of Motorola’s full-featured flagship solution makes it ideal for mission critical ASTRO® 25 Land Mobile Radio (LMR) systems.

Meet today’s demand for IP networks and narrow-band radio operations with the high performance GTR 8000 Base Radio / Expandable Site Subsystem. The GTR 8000 surpasses the bar previously set by QUANTAR™ offering software-based upgrades and migrations, no single point of failure, hot swap hardware, front access serviceability, and integrated battery charging. Its state of the art compact design enables everything from basic Analog Conventional to advanced P25 TDMA Trunking on the same hardware. The GTR 8000 ships tuned from the factory for quick and easy deployment.

Features and Benefits

Due to the FCC Narrowbanding mandate in the United States, product specifications and brochures for Motorola Solutions two-way radio products may indicate 25 kHz/12.5 kHz analog/digital operation which may not be the standard mode of operation at the time of shipment after Jan. 1st 2013.


 ASTRO® 25 Trunking
GTR 8000 Expandable Site Subsystem (ESS), Motorola's premier turnkey RF site design, provides the optimal P25 trunking solution for easy installation and high availability. All base radios, networking equipment, timing and frequency distribution, RF combining and multi-coupler equipment are factory integrated into a single rack or cabinet.
ASTRO® 25 & Analog Conventional
Motorola's Conventional channel solutions range from small single repeater sites to wide-area coverage voting and simulcast systems. The GTR 8000 Base Radio's high performing analog capabilities enable narrow-banding migrations that maximize audio performance.
 ASTRO® 25 Data
Motorola's Integrated Voice and Data (IV&D) in ASTRO® 25 trunking and conventional systems as well as High Performance Data (HPD) are supported by the GTR 8000. Voice and data transmissions switch dynamically on the same base radio for ease of use.
3600 Trunking
The GTR 8000 base radio supports 3600 trunking operation, enabling new future-ready base radios to be added to existing SmartZone systems with SmartX. The GTR 8000 is software upgradeable to P25 trunking when the time is right to migrate to P25. 3600 trunking operation is available on both simulcast and IntelliRepeater systems, in either analog or digital mode.



Maximum Coverage
Multisite Linear Simulcast offers industry-leading coverage with fewer sites

Receive Diversity
Two branch diversity receiver expands talk-in coverage for HPD and TDMA trunking

Superior Audio
100 ppb frequency stability directly enhances analog audio performance

Dual Connections
All channels remain online and on air in the event of a network switch or timing/frequency reference failure

Battery Revert and Charging
Eliminates need for an uninterruptible power supply (UPS) in many installations


Installation & serviceability
Easy Install
Ships factory aligned ready for installation

Hot Swap Hardware
Service and replace hardware without system down-time

Online Software Download
Download software while online and fully operational

Front Serviceable
Perform all servicing from the front of the station

Space efficiency
Compact Hardware
Standalone deployment utilizes a 3 rack unit chassis

Reduced Number of Racks and Cabling
Expandable Site Subsystem conserves power and space by integrating controllers, switches, cavity combining, TX filtering, multicouplers & preselectors into one vertical cabinet/rack

Front Access Connections
Install within inches of the wall and save valuable site space


Life expectancy
Future Ready
No new hardware required to convert for narrow-banding, from conventional to trunking, from 3600 trunking to P25 trunking, from FDMA to TDMA, or from single to multi-site configurations

Software Defined Radio
Upgrade to new functionality through software updates and configuration changes

Password Protected
Password-only, user/password, and RADIUS server authentication configurations are supported

Secure Connectivity
Secure SNMPv3 and secure shell (SSH) IP connectivity provided with Microsoft Windows® Configuration Service Software

Robust, Hardened IP Stack
Built to comply with Department of Defense STIGs for secure network communications
