Motorola Astro 25 Expandable Site Subsystem, ie: “6
pack”. This is a 6 Channel VHF 136-174 Mhz expansion site that
comes complete with the following equipment:
(6) GTR8000’s VHF Repeaters
(2) GCP Site Controllers
(1) Optional Combining Equipment is available.
We would need to have the exact frequency in order to provide a quote for
Transmit Combiners, Receiver filters and multicoupler.
System is fully operational and comes with everything you see in the photos. You are welcome to come to our staging facility and preview the equipment prior to purchase. We can program the system to your freqs for an additional fee, we would need to know the frequencies in order to provide a staging quote. This system will consist of 1 rack and will require freight shipping. We will cap the shipping at $250.00 ONLY for lower 48 states. If you have any questions, please contact us.
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 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.
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.
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.
Multisite Linear Simulcast offers industry-leading coverage with fewer sites
Two branch diversity receiver expands talk-in coverage for HPD and TDMA trunking
100 ppb frequency stability directly enhances analog audio performance
All channels remain online and on air in the event of a network switch or timing/frequency reference failure
Battery Revert and
Eliminates need for an uninterruptible power supply (UPS) in many installations
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
Perform all servicing from the front of the station
Standalone deployment utilizes a 3 rack unit chassis
Reduced Number of Racks
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
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-only, user/password, and RADIUS server authentication configurations are supported
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
