● Intuitive "Object Oriented" User Interface Design --
Designed for ease of use, yet powerful enough to satisfy the most
sophisticated expert. Common data entry, browsing and control methods are used
for non-trunked conventional channels, trunking talkgroups, search
configurations and Spectrum Sweeper setups. The radio grows with you - start
out with a small and easy to manage configuration and expand it as you need
to.
● Menu Driven Programming with Context Sensitive Help -- Each
menu item provides a few lines of help text that provide assistance with
programming and using the scanner.
● Upgradeable CPU and DSP Firmware -- You can easily keep
your scanner current with software enhancements as they become available with
free upgrades from
GRE America.
● Flexible Free-Form Memory Organization -- Memory is
assigned as objects are created using a sophisticated internal file management
system. You are not constrained to traditional bank/channel scanner memory
layouts. No memory is wasted as a result of bank/channel programming
constraints. The scanner has sufficient main memory capacity to store over
1800 conventional channels, trunking talk groups, search configurations and
Spectrum Sweeper objects in any combination. This provides amble capacity for
more sophisticated hobbyists and professionals while keeping the database size
manageable for beginners.
● GRE's Exclusive V-Scanner Technology -- Allows you to save
complete radio configurations within the radio for recall into main memory as
needed in the field. This is similar to having a laptop computer and
programming software available anytime. You can use V-Scanners to store
configurations for different geographic areas or usage styles. Twenty-one
V-Scanner folders are provided, each capable of storing over 1800 objects.
Total memory capacity of main memory combined with V-Scanners is over 39,600
(1800+37800) objects.
● Multi-System Trunking -- Scan most common trunked system
signaling formats, including Motorola, EDACS Standard, EDACS Narrow, LTR and
P25 trunked radio networks. These new scanners will not trunk
M/A-COM proprietary modes such as Open Sky and ProVoice. Talk group call and
individual call monitoring are supported. Supports trunking operation in
virtually any land mobile band including 700 MHz and the new US DoD 380-390
MHz band.
● P25 NAC Functionality -- Much like CTCSS and DCS with
analog signals, a P25 Network Access Code (NAC) is used to provide selective
squelch operation on conventional P25 channels. These GRE digital scanners
will detect the NAC that is being used on a P25 conventional digital channel,
and will allow the user to program NAC codes to block transmissions that do
not have a matching NAC, including analog traffic on the same frequency.
● Audible alarms -- Programmable audible alarms can be
configured to sound when certain objects are active. Can be used in
conjunction with, or separately from, the ALERT LED feature described above.
● GRE's Exclusive Automatic Adaptive Digital Tracking -- When
monitoring Motorola and P25 digital systems, instantly adapts the digital
decoder to the digital modulation format of the transmission signal, then
analyzes the digital signal 50 times each second and adapts to any subtle
changes caused by multipart signals or fading. No cumbersome manual
adjustments are required.
