When it all goes down, ALERT AM stays up.
Hundreds of communities across America operate ALERT AM Emergency Advisory Radio Stations to tell citizens what to do during 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 controlled over a network, USB, landline/cellphone or via a two-way transceiver provided by the operator. Two redundant voice systems, both operable locally or remotely, provide full audio system control which continues to function should telco, network or building access would be lost.*

The ALERT AM system allows the operator to pre-record messages for quick broadcast as anticipated emergency scenarios present themselves.

Broadcasts may also be triggered by ancillary devices, i.e., siren-system closures, switches or other external sources. This allows ALERT AM to quickly switch from broadcasting general information to specific emergency information if disaster strikes. When the National Weather Service issues all-hazard Emergency Alert System alerts for designated counties, they are broadcast automatically, interrupting standard programming. ALERT AM also allows the operator to lock out NOAA alerts if desired. Broadcasting live is easy with the push of a button and can be effected at the radio station itself or remotely from any telephone. An audio processor is onboard to boost ALERT AM’s audio quality and receivable range.

ALERT AM’s digital message players 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 two most common formats:
  • Yard Style: ALERT AM may be installed at a building with the electronics securely indoors and the antenna pole mounted in the adjacent yard connected by an underground cable. This style is recommended because it is most economical and affords the greatest security for equipment. A 50’ separation from buildings is recommended.
  • 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, two-way or network service.
If a yard- or isolated-style installation is not possible, custom installation on a building roof is possible in some instances. Lateral separation of the antenna from large, nearby objects by at least the height of the object is suggested to prevent signal degradation.

We can provide documentation that radio frequency exposure from the ALERT AM antenna does not exceed FCC limits for safe operation.
Planning and Purchasing Your System
See Typical Planning Steps for the ALERT AM system and/or contact Bill Baker for assistance in planning the best configuration for your setup. Bill can then provide a formal quote. See optional methods of purchasing.

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.


As you would expect, Information Station Specialists provides a full menu of technical services to help you put and keep ALERT AM system on the air. We are here to help, even with professionally recorded audio messages, so your broadcasts are ready to air as soon as your station is turned on.

Best of all, each system comes with
Remote Technical Support for the life of the station.

For extended range emergency broadcasting, see RadioSAFE Wide Area Emergency Broadcast Radio Systems, which offer coverage areas of 5 to 20+ miles in 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, four-day operational battery backup and GPS frequency stabilization options described above.

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.
