"The Washoe County Health District (WCHD) utilizes the [VoiceStar] AM radio station to provide up-to-date information to the public on vaccine administration and operations at our large scale COVID-19 testing and vaccination site. WCHD has four radio capable units which are part of our region's emergency redundant communication system and WCHD partners with our local Amateur Radio Emergency Services (ARES) organization on emergency communications planning."

While their utility in disaster response is self-evident, they provide a valuable component to exercises, vaccine clinics and whenever we need to communicate information to a continuous stream of community members.

Powered by a robust array of solar panels and large battery backup, VoiceStar stations can go anywhere, anytime. They are built to operate in isolated locations. The radio messages and sign text may be programmed locally or remotely via cell modem.

VoiceStar has 'quick startup' and can be broadcasting and/or providing its message display at a ew location in fewer than 5 minutes.

After parking, the operator swings up the antenna, lays out the portable groundplane and flips on the power. Batteries are immediately online. If AC power is available, the operator has the option of plugging in and charging the system’s batteries while operating. The solar array is aligned to allow positioning of the trailer in any roadway orientation.

This allows the operator to change frequencies or change to a backup transmitter on the fly.

Frequencies & Licensing
VoiceStar Portable Information Radio Stations are licensed on frequencies 530 to 1700 kHz AM, secondary to standard AM broadcast stations. 

Via solar wireless communication, operators can program broadcast messages and the changeable sign display remotely. Range is 3-5 miles (25-75 square miles) across average terrain. The FCC’s special “broad area” license (good for 10-years and renewable) affords operators a territory in which each VoiceStar may roam. Licenses can also specify a fixed operation point, if desired.

See our Frequency Search / Licensing page where you can download a form to complete and return, requesting this service.

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.
