Customer Review

"I want to thank Information Station Specialists for their assistance in designing and refining this concept into something highly user friendly and important to our response plans. They provided assistance in frequency monitoring and selection, FCC license application; and they listened to our feedback on what was needed and could afford.”

Step 1: Order a frequency search.

Contact us to order a frequency search. All we need is the geographic area where the system might be operated. We will develop a list of available AM frequencies and send it to you with our suggestions and instructions on how to monitor them.

See more about our frequency-search/licensing services.

Step 2:  Survey listening areas.

Survey (with an automobile digital AM radio tuned to your candidate frequencies) the streets, roads and highways where listening is required. Monitor all of the candidate frequencies throughout the listening areas at least once during daylight hours and at least once after dark. Report your results to us on a form like this (to key your results right on the form, right-click on this interactive version, "Save As" to your desktop. Then open, complete and submit it from there. You cannot open the interactive version in your internet browser.)

Step 3:  Choose an operating location for optimum coverage.

Use a map to select a general operating location for VoiceStar such that a 3-mile-radius circle fully encompasses the highways requiring coverage. The signal will usually carry 3 to 5 miles and be heard much farther away on some radios; but the strongest part of the signal will always be in this radius. If a specific highway or intersection is critically important to cover, consider locations immediately adjacent to the roadway. Mark the map to show the area within which the antenna should be located to meet your coverage goals. Consider where changeable message signs or portable static signs will be placed to announce to motorists entering the area that the signal is available.
Step 4:  Survey the intended site for your VoiceStar station.

For best coverage, the immediate location should be free of objects that exceed 25 feet (about 2 stories.) This includes tall buildings, trees, terrain features, lighting, power and communication poles and towers, overpasses and highway signs. Make certain that there is a 20'-by-20' area of open ground to park the trailer and deploy the portable FlexPlane groundplane (Patent #5,495.261).
Step 5:  Complete a FCC License Application Questionnaire.

Request a simple VoiceStar License Application Questionnaire, so we may secure your operating license from the FCC in a timely manner. The questionnaire requests basic contact information and details about the proposed antenna location and frequency chosen for broadcast, with which Information Station Specialists can also assist you. When we receive your completed questionnaire, we will prepare the necessary engineering work and submit your application to the FCC for approval, which often takes a few months. As part of an overall license package, we will handle any additional filings you may require to get up and running, such as temporary licenses, minor adjustments and the required FCC notification that your station has been built.

NOTE 1: Because FCC processing time is unpredictable, we recommend you request licensing and other FCC documentation services as soon as you know for sure you will have a station – definitely no later than when you place your radio equipment order.

NOTE 2: The FCC considers 10-year, renewable licenses for information radio stations secondary to full-power broadcast stations. This means, that in a rare situation in which a full-power station might move into a given area, an advisory radio station already in that vicinity might need to change frequency. We can assist.   
Step 6:  Consider options and services.

Variables to consider:
Step 7:  Know your cellular telephone service.

At the time of your equipment order, we will ask for a contact name at your cellular telephone provider. The appropriate cellular service format must be available from your provider.
Step 8:  Configure and order your system.

For personal planning assistance, contact Bill Baker (phone 616.772.2300 x102) of Information Station Specialists or Casey Inoue (phone 770.448.6650 x112) of American Signal.

Information Radio Stations is a generic term synonymous with Travelers Information Stations (TIS), Highway Advisory Radio Stations (HAR) / Highway Information Systems & Low Power Radio Stations (LPR). Operation of the stations is governed by FCC Part 90.242 Rules. A FCC license is required. Information Radio Stations may be fixed or portable. Subcomponents may include transmitter, antenna and ground system, digital voice player, wateter, cabinet with conventional or Corbin locks, lightning arrestors for RF, power and telephone lines, coaxial cable. Most stations employ black maximized antennas to discourage ice accumulation and security measures to prevent unauthorized program access. Options include synchronization, battery backup, solar power, remote programming by local, network or telco, multi-station audio distribution via RF or LAN / WAN or wireless network.
