This digital trunking scanner employs cutting edge technology to bring a high level of performance and innovative features. The intuitive Object Oriented User Interface is designed for ease of use. This model clearly raises the bar in the area of advanced trunking scanners.

Intuitive "Object Oriented" User Interface Design
- 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 access to frequencies used by storm spotter networks. You can monitor storm conditions as they occur, and become aware of 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 Specific Area Message Encoding (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. Both talkgroup and individual call monitoring are 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. This makes the radio easier to listen to, and provides you with a more enjoyable scanning experience.

LTR Home Repeater AutoMove
- Takes the guesswork out of programming LTR trunking systems when the home repeater order is not known. Enter the LTR system frequencies in any
order, and the PSR-500C will automatically move the frequencies to the proper home repeater slots as transmissions are received on the system.

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 scannerʼs frequency ranges for transmissions from nearby sources. When a nearby active frequency is found, the scanner automatically tunes to that frequency and receives the traffic.

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 PSR-500C 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. 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 Scannable Objects are active. Can be used in conjunction with, or separately from, the ALERT LED described above.

High Speed PC Interface
- uses GREʼs 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.
