Introduction
Welcome to an exciting new world of radio scanning!
Recognizing that contemporary scanning receivers are too hard
to program and use, GRE!s engineers conducted extensive
research to determine the functional requirements for an entirely
new scanning receiver user interface. We call this new user
interface the Object Oriented User Interface (OOUI), and it is
based on the premise that, to a hobbyist, a scanner is easiest to
use if all of the things that can be scanned are handled using
common conventions for interaction between the user and the
radio, at least to the extent that this is possible given that the
“things” that can be scanned are different from one another in
either subtle or major ways.
In this new user interface design, we call “things” that can be
scanned Scannable Objects. Simply put, a Scannable Object is
defined as something that can be scanned or monitored.
Scannable Objects include the following:
•Conventional, non-trunked radio channels
•Trunked talkgroups used on a trunked radio system
•Service searches to search for a specific radio service
•Search ranges with upper and lower limits
•Spectrum Sweeper setups with band segments that can be
enabled or disabled by the user
One of the goals of the Object Oriented User Interface is to make
the scanner as easy to use as possible. The OOUI does this by
treating all Scannable Objects the same in terms of how they are
created, edited, manipulated and grouped. Once you have
learned how to create and store a conventional channel, you
know most of what you need to know to create a trunking
talkgroup, and so on.
While we have designed this radio to be the easiest scanning
receiver in its class to program and use, we encourage you to
read this manual in its entirety so that you will fully understand all
of the radio!s capabilities. However, if you consider yourself to be
an experienced scanning hobbyist and are feeling adventurous,
we invite you to dive right in and get started programming your
favorite “objects” into the radio.

Features
Upgradeable CPU and DSP Firmware - keep your radio current
with enhancements as they become available with free upgrades
from www.greamerica.com!
Intuitive "Object Oriented" User Interface Design is designed
for ease of use, yet powerful enough to satisfy the most
sophisticated experts. 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 – you can start out
with a small, easy to manage configuration, then expand it
whenever 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.
Powerful and flexible Scan List functionality allows you to
arrange, group and scan objects according to your preference.
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 1,800
conventional channels, trunking talkgroups, search
configurations and Spectrum Sweeper objects in any
combination, providing ample 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 geographical
areas or usage styles. Twenty one V-Scanner Folders are
provided, each capable of storing over 1,800 objects. Total
memory capacity of main memory combined with V-Scanners is
over 37,800 objects!
SKYWARN Storm Spotter Functionality - Instant, one button
access to frequencies used by storm spotter networks. You can
monitor storm conditions as they occur, and become aware of
0715 User Manual"Page 2
dangerous conditions before the media or emergency
management officials are able to announce them to the general
public.
SAME and All Hazards Weather Alerting - Your scanner can
operate in dedicated SAME weather alerting mode, and alert you
to severe weather and other hazards in the specific area(s) that
you select, or, your scanner can check your local NOAA weather
frequency periodically, even while scanning and alert you when
an All Hazards alert occurs.
Multi-System Trunking - Scans most common trunked radio
system signaling formats, including Motorola, EDACS, LTR and
P25 trunked radio networks. Talkgroup and individual call
monitoring is supported.
GRE's Exclusive Automatic Adaptive Digital Tracking - When
monitoring P25 digital systems, instantly adapts the digital
decoder to the digital modulation format of the transmitted signal,
then analyzes the signal over 50 times each second and adapts
to any subtle changes caused by multipath or fading. No
cumbersome manual adjustments are required.
GRE's Exclusive Digital AGC - instantly compensates for low
user audio levels that are very common on digital systems. The
radio is easier to listen to, and provides you with a more
enjoyable scanning experience.
The Best Subaudible Squelch Decoder in the Scanning
Industry - CTCSS and DCS subaudible squelch coding is
processed by the same powerful DSP chip that is used for P25
digital decoding. Provides fast and reliable decoding of
subaudible squelch signaling with squelch tail elimination.
Powerful Spectrum Sweeper - Quickly sweeps the scanner!s
frequency ranges for transmissions from nearby transmitters.
P25 NAC Functionality - Much like CTCSS and DCS with
analog signals, P25 Network Access Code (NAC) is used to
provide selective squelch operation on conventional digital
channels. Your 0715 will detect the NAC that is being used on a
P25 conventional digital channel, and allow you to program NAC
codes to block transmissions that do not have a matching NAC,
including analog traffic on the same frequency!
Exclusive ALERT LED - Programmable tri-color LED can be
configured to illuminate or flash when certain objects are active.
0715 User Manual"Page 3
Eight user-defined colors and brightness levels can be specified
from thousands of possible combinations. Provides visual alerts
when certain channels are active, e.g., blue can be used to
signal activity on your primary police channel, red for fire, etc.
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
described above.
High Speed PC Interface - uses GRE!s 30-3290 USB cable in
full duplex mode at 6 times the speed of previous scanner
models for PC transfer and 8 times the speed of previous models
for radio to radio cloning.
Real-time Signal Strength Indicator – shows relative strength
of received signals.
Sleek, compact case design with large speaker is designed
for one-handed operation and ease of use.
Overview of the Object Oriented User Interface
Background
Scanner hobbyists who have been involved in the hobby long
enough probably remember the days before microprocessor
technology reached the point where it feasible for use in
everyday consumer devices. Back then, scanners were relatively
limited in what they were able to do. A typical scanner was able
to scan between 2 and 10 frequencies. The frequencies were
selected using plug-in crystal elements, and a custom crystal had
to be purchased for each frequency that a user wished to scan.
Scanning activity was typically shown using a row of
incandescent or LED indicators. These indicators would show
scanning operation in progress as the scanner moved from one
channel to the next, looking for activity, and would indicate the
active channel when activity was found. Pushbuttons or switches
were used to skip or lock out undesired channels. The scanning
row of LED or incandescent indicators seemed to personify the
hobby at the time, and it was quite an experience to see the light
show from multiple radios in a well-equipped scanner shack
Early microprocessor controlled scanners eliminated the need for
crystals and increased the number of channels that could be
scanned. Without keypads and numeric or alphanumeric displays
these early microprocessor controlled radios still relied on the
0715 User Manual"Page 4
traditional row of lights to show scanning activity. A row of
switches was used to enter binary code to store individual
frequencies. In some later models a punch card or metal comb
was used to load the binary code.
The true predecessors of today!s modern scanning receivers are
those first radios to use a numeric keypad to store frequency
information and control the radio, and numeric LCDs to show the
programmed information and display the status of the radio. The
row of lights was replaced with a row of zeroes or other display
elements in the LCD to show scanning activity.
As it became possible to increase the memory capacity of these
microprocessor controlled scanners, designers started looking
for ways to organize this expanded memory to make operation
easier for users. This lead to the typical bank/channel memory
organization that is still used in many scanning receivers today.
This design works well when scanning conventional, non-trunked
frequencies.
Trunking presented new challenges for designers. Early designs
operated in trunking or conventional mode, but not both at the
same time. Because programming for trunked systems includes
many parameters not normally used in conventional radio
scanning, it was necessary to design a completely separate user
interface for entering trunking parameters and scanning trunked
systems. Soon after the first early models were released, new
“multi-scanning” receivers appeared that allowed users to scan
different combinations of trunked systems or conventional
channels simultaneously.
Trunking scanners soon earned a reputation for being complex
and difficult to program. Even experienced expert users were
frustrated when confronted with the challenges of programming
and operating a trunked scanning receiver. Part of the problem
with trunking scanners was the way that trunking functionality
was added to the radio. Until recently, trunking functionality was
forced into the traditional bank/channel scanner design. This
created confusion and frustration for users, who had to learn two
different methods for programming and controlling their scanners
– one for conventional, non-trunked channels, and another for
trunked systems and talkgroups.
GRE!s engineers have studied the challenges of programming
and operating today!s current crop of trunked scanning receivers.
We have also carefully studied how scanning hobbyists like to
use their radios, and the role the Internet plays in the scanning
0715 User Manual"Page 5
hobby. We have studied the scanning hobby itself, which has
changed dramatically over the years as radio systems, scanning
receivers and scanner hobbyists have all become more
sophisticated. Sophistication is a generally good thing, but in this
case it can have the effect of locking out newcomers to the
hobby.
Our engineers decided that an entirely new method of
programming and controlling scanning receivers was needed –
essentially, a new user interface. Several design objectives were
defined. These included the following:
•There should be a strong focus on ease-of-use. The radio
should do as much work as possible for the user. A brand
new hobbyist should be able to begin using the radio quickly
with minimal frustration. There should also be enough
advanced features and functionalities to satisfy the most
sophisticated expert users.
•The user interface should be intuitive. Interactions with the
radio should be standardized to the extent possible. For
example, the same basic methods should be used whether
adding a new conventional channel or adding a trunked
talkgroup.
•The scanner should include efficient memory usage. Bank/
channel designs result in much wasted memory. Memory
should be allocated as it is needed for new objects.
Our engineers realize that our scanners are used by a wide
variety of users with varying levels of experience and expertise.
These include amateur radio operators, scanner hobbyists, fire
buffs, railfans, public safety professionals, volunteer firefighters,
news and media organizations, and most importantly, everyday
people who just want to know what is going on around them.
All of these users have a few things in common about the way
they use scanning receivers. First, they all follow the same basic
process when configuring and programming the radio for use.
Second, all have one or more collections of frequencies,
talkgroups, or other things they listen to.
As our engineers studied the scanning hobby and those who use
scanners, they began to realize that the scanning hobby had
much in common with hobbies that involve collections, like stamp
collecting, coin collecting, and so on.
