Overview of a GTR 8000 Base Radio in a Trunked 3600 System
In a trunked 3600 system, the GTR 8000 Base Radio control channel runs at 3600 bps, and the voice
channels can be configured for analog or ASTRO
®
25 voice operation.
The base radio can be used in the following trunked 3600 SmartZone
®
systems:
• Trunked SmartX – 6809/MTC 3600 Site Controller Simulcast Subsystem
Depending on the system capabilities, each base radio can be configured for analog voice (4-wire
interface), digital voice (V.24 interface) or mixed-mode (4-wire and V.24 interfaces). These interfaces
connect to either a channel bank or ASTRO-TAC 3000 Comparator.
The base radio is available in the following frequency bands:
• 800 MHz
• UHF R1 (380–435 MHz)
• UHF R2 (435–524 MHz)
• VHF (136–174 MHz)
NOTICE: A GTR 8000 Base Radio can be implemented as a QUANTAR
®
replacement within a
trunked 3600 SmartZone
®
system. The implementation details can be found in the Quick Guide
for Replacing a Trunked 3600 QUANTAR with a GTR 8000 Base Radio manual.

Power Efficiency Package
The GTR 8000 Base Radio is available in a Power Efficiency Package, which provides low standby
power consumption (see Table 2: Standby Power Consumption
on page 39) functionality for ASTRO
®
25 Conventional base radios and trunked base radios operating in the UHF-R1 and UHF-R2 frequency
bands. The Power Efficiency Package optimizes the power consumption for supported base radios for
the use of power generated from alternate energy sources such as solar or wind.
