When it all goes down, the ALERT AM System stays up.

Hundreds of communities and transportation departments across America operate ALERT AM Emergency Advisory Radio Stations to tell citizens what to do during highway travel and incidents that threaten life and property.

No power? No internet? No problem. With the ALERT AM system, listeners receive up-to-the-minute reports and instructions across a 3-5 mile radius (25-75 square-mile area) with a level of detail that makes the broadcasts invaluable.

During non-emergency times, officials use the stations to inform motorists of street repairs, traffic constraints, travel advisories, city history and visitor information.

Message Control

The ALERT AM broadcast program can be managed on a network (LAN / WAN) with a local USB / flash-drive backup control method. Program automation software is not required. A multi-channel program mixer is present so the live microphones and live feeds can be mixed in during emergencies or special events.

Message recording software comes with ALERT AM so you may pre-record messages files (mp3), keeping them for quick retrieval as emergency scenarios present themselves.

When the National Weather Service issues a warming, it broadcasts immediately, interrupting standard programming and automatically resetting. An audio processor is onboard to boost ALERT AM’s audio intelligibility and receivable range.

Your message library can be stocked with pre-recorded emergency management messages prepared by our professional announcers. to illustrate what’s possible within the system. See free or commissioned recording services.

Antenna Styles

The most common formats are described below. Click thumbnail images (right) to see a full view of each example.

  • Yard Style: ALERT AM's antenna may be installed at a building with the electronics securely indoors and the antenna pole and groundplane located in the adjacent yard, connected by a coaxial cable. This style is a recommended first choice, because it is most economical and affords the greatest security for equipment. A 50’ separation from buildings is recommended. We can even provide the mounting pole for yard areas with limited room grounding.

  • Flat-Roof Style: If no earth surface location is available, a flat building roof may be your best choice for antenna installation. We can provide an installation package which requires no roof penetrations.

  • Isolated Style: At remote locations where there is no building, a weatherproof cabinet containing the electronics is attached to the antenna support pole. The location must have electrical power and, if equipment is to be remotely controlled, telephone or network service.

ALERT AM can be installed by you, your agent or as a service by us. Included in the package are the FCC type-accepted transmitter, digital message system, cabinets, antenna, preassembled groundplane, lightning arrestors, cables, connectors, mounts, hardware and illustrated instructions.  

Planning & Purchasing Your System

We We provide a full menu of technical services to help you put and keep your ALERT AM station(s) on the air. We will help plan and implement your station, including frequency and site selection, FCC licensing, installation, staff training and the FCC-required field survey and documentation. Even professionally recorded audio messages are available, so your broadcast is ready to put on the air as soon as the station is turned on. Best of all, each system comes with remote technical support for the life of the station.

See typical ALERT AM planning steps and / or contact Bill Baker for a recommendation on the best setup for your intended application. Bill can also supply related pricing.

See Purchasing Method Options here.

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

For extended range emergency broadcasting, see RadioSAFE Wide Area Emergency Broadcast Radio Systems, which offer coverage areas of a 5 to 20+ mile radius. The Information Station is a lower cost alternative with many of the same messaging capabilities as ALERT AM but without the specialized 'all hazard' broadcast capability, the same operational battery backup and GPS frequency stabilization options described above.

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, wattmeter, 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.
