For Intelligent Transportation Systems 
Our ITS6000 Highway Advisory Radio (HAR) Systems provide new and efficient ways to integrate real-time radio into 21st century ITS projects. Radio is as relevant as its content is current. ITS6000 HAR Stations are designed to make broadcast content match current conditions to maximize utility to motorists.

Conventional Highway Advisory Radio design, kicked up a notch, ITS6000 offers operators the ability to record 3 hours of recordings, 1,000 high quality messages in 50 playlists and, if desired, automatic 'All Hazard' alerts from the National Weather Service, targeted to areas served (e.g., hurricane updates and AMBER alerts). Two-way redundant control, standard with each station, uses push-to-talk style transceivers (transceivers not included) and the same, familiar broadcasting protocols and voice prompts as regular phones. Computer audio control is an option.   
Other Standard Features 
  • Antenna system.
  • Independent recording, monitoring and erasing of recordings.
  • The NX8R Digital Message Player offers 3 hours of recordings, 1,000 high quality messages in 50 playlists and 'All Hazard' alerts from the National Weather Service targeted to the area served through Specific Area Message Encoding (SAME). Non-volatile dynamic message storage.
  • Remote control.
  • 4-day battery backup operation, if AC power is lost.
  • Rack-style signal cabinet for high security and multiple option flexibility.
  • One-of-a-kind TR6000 HQ5.0 transmitter system.
In addition to staff training and system certification, we offer the following optional services.
Exclusive Features in the Marketplace  
1. System components manufactured in the United States.  
2. Only our transmitter (TR6000 HQ5.0) features full 5000 Hz audio bandwidth to comply with new FCC rules that allow for high quality broadcasting. The transmitter employs a modern synthesized frequency system, so that if a frequency change ever is necessary, it can be easily done without component changes or board-level work. The TR6000 Transmitter also utilizes an efficient Class D amplifier, comprised of only two driver devices for highest reliability. Moreover, TR6000 is the only such unit manufactured and type-accepted for Travelers Information Station (TIS) applications in the United States, and it is approved for military use on 510-530 kHz, 1610-1700 kHz - Certification: J/F 12/07677. (An optional HQ5.1 broadcast quality audio processor incorporates tight peak control, adaptive pre-emphasis and low-pass filtering. Meets new FCC audio filtering standards for expanded bandwidth Travelers Information Radio Stations [TIS]. Certified by the FCC on 2-18-2016 for exclusive use with the TR6000 Transmitter.) 
3. Ability to  change to new message patterns, when the National Oceanic and Atmospheric Association (NOAA) All-Hazard Radio System sends warnings related to specific hazards and/or geographic areas.  
4. Field-programmable/upgradeable 'All Hazard' Receiver to remain current with changes in NOAA Emergency Alert System/weather hazards.  
5. An ENcast option to allow for instant broadcast of text-based alerts issued by your Emergency Notification System (check for compliance) and/or National Weather Service SAME/'All Hazard' system. 
6. Ability to capture the most recent warning activation for replay by system operators.  
7. Ten prerecorded touchtone bursts and burst sequences to program into broadcasts to gain attention for important messages.  
8. Optional ability to distribute audio to satellite stations without relying on vulnerable dial-up telephone links. (See the GPS Frequency Stabilization webpage.)  
9. Black antenna to discourage ice build-up, finished with a special UV-resistant architectural-anodization process to prevent color fading.
10. An option requiring that only a support pole be set. Not required are large, buried, copper-wire groundplane installations or chemical-emitting ground-pipe (hollow rods) burial. (See Vertical Profile Antenna Support and Grounding System webpage.
11. Battery backup system capable of keeping the station on the air for a full 4 days. The pack recharges full in only 7 hours.  
12. Nonproprietary electronic designs. All equipment uses standard 19" rack-mount hardware for ease of substitution and service. This means that, in the future, you may change components as needed without the requirement to return to us; i.e., simple wiring diagrams are provided, so you can service equipment yourself, if you choose, or have a third party assist – all with our full support.
13.  A supplier that offers technical assistance for the life of the product. We support today radio stations that first went on the air in the 1980s when the company first started. Our staff of engineers has more than 60 years of combined experience specifically in the kind of radio technology under which ITS6000 operates (FCC Rules, Part 90.242).
14.  Free professional recording service option.
