“The City of San Marcos utilized the station to keep our residents and visitors updated on critical fire information, including evacuation and shelter information. During this time, 10 different messages were quickly and easily uploaded …and broadcast to the community. It worked great.”

Below are things to consider in setting up RadioSTAT station in your area. Feel free to email us for personal planning assistance (or call Bill Baker at 616.772.2300 Ext 102). We have a network of representatives across the country. And after initial brainstorming, can put you in touch with one in your area who can visit your site(s), help test frequencies and find the best antenna location(s) — even install the system, if you like — whatever is needed.
Step 1 - Order a frequency search.
You must have a FCC license in hand to operate. We will assist you in obtaining it. 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.

The FCC grants 10-year-renewable and Special Temporary Assignment (STA) licenses. STAs are quicker to get and can be requested first. The FCC considers 10-year, renewable licenses for this type of station secondary to full-power broadcast stations, which means, that in a rare situation in which a full-power station might move into a given area, your station in that vicinity might need to change frequency. We can assist.

Contact us to order a Frequency Licensing Package. This package includes a list of frequencies the FCC will assign to your area, as well as a Signal Monitoring Radio Receiver to assist you in determining which frequency is best. We work with you every step of the way in selecting the operating frequency for your station.
Step 2 - Survey onsite listening.
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 complete coverage.
Select an operating location for each RadioSTAT station such that a 3-mile-radius circle fully encompasses the highways requiring coverage. The signal usually carries 3 to 5 miles and can be heard much farther away on some radios. However, the strongest part of the signal will always be within this radius.

Consider where signs will be placed to announce to motorists entering the coverage area that the signal is available.

The RadioSTAT system can be operated in a fixed location permanentlty or kept ready to roll to events as needed. The USB Edition is generally chosen for portable applications and the IP Edition for permanent fixed locations.
Step 4 - Choose a specific location for each station.
For the best coverage, the immediate antenna location should be free of tall objects that will crowd or overshadow the antenna. 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 set up the station's antenna and deploy the portable groundplane.

An optional Vertical Profile Antenna Support and Grounding System (VP.9000) is available if you'd like to operate the RadioSTAT station in a fixed location most of the time. Only one square foot of open-ground area is needed for installation. All wiring is inside the pole. VP.9000 is aesthetically pleasing, highly secure and the only antenna solution that meets hurricane wind standards in all parts of the United States. It can be installed near a building or in isolation.

An optional 2X Signal Booster offers up to double the efficiency/range of the station’s antenna, allowing the transmitter to run at less wattage or allowing the signal to have twice the signal intensity at a given distance. It functions with upper-band (typically 1610-1700 kHz) antennas only and is recommended for federal government agencies that do not have a signal intensity limitation; also for any operator in a challenging environment that requires maximum signal intensity to cut through woods, buildings and obstructions. (NOTE: local government licensees must seek a waiver of the FCC rules to allow a signal intensity above the standard 2.0 mV/m limitation.)
Step 5 - Consider equipment, options and services you might need.

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.
