Although it has been in use by interpreters for more than 20 years, the InfOspot License-Free Radio Station that is being re-introduced by Information Station Specialists is a much improved entry – with enhanced audio, flexibility and range. Parks, historic sites, wildlife viewing areas, unattended visitor / nature centers and interpretive kiosks commonly employ these micro-radio stations to get aural interpretation to people in cars approaching, parking or traveling through sites. Each InfOspot station has up to a half-mile range and, coupled with instructive signs, can be a useful tool for instructing and providing visitors information about the site  ̶  especially in ADA applications.

There are few restrictions on content, per FCC Part 15 Rules, which allow an operator to include music or even sponsorships to defray costs.

One of InfOspot’s newest subcomponents is its RE2.5 Range Extender Outdoor Antenna and Tuner with coaxial cable connection. InfOspot is the only certified license-free radio system with a coaxial cable link in its FCC-approved design. This allows the transmitter to operate in a protected location that can be conveniently monitored – safe from theft, wind damage, moisture intrusion and lightning. It also allows the transmitter’s antenna to be positioned at a high point on a building or pole, enhancing range. Several options are available to customize an InfOspot station packages to exact application needs, including audio quality and connectivity enhancements; outdoor cabinets, and more.

With all these advancements, cost has been contained to less than $500 for a basic station package that includes lifetime product support, the transmitter with its internal dual-message digital audio player, the new Range Extender Antenna/Tuner with mount and 25’ of RG6 coaxial cable.

On August 5th the Hobby Broadcaster Part 15 website/forum evaluated the new Range Extender, comparing it to its predecessor, and published this review.

Nez Perce National Historical Park in Idaho has operated an InfOspot system since 2007 to interpret sites whose isolation and absence of visitor services pose particular management challenges. The Park’s existing transmitter has operated four years without interruption, in all weather; and the Park's confidence in the system led to expanding it to several locations. See a summary.
