Limited Range   Unlimited Flexibility
Introducing the first professional, license-free radio station available for government, nonprofit and individual applications. InfOspot is an affordable solution for local area broadcasting, offering the widest latitude in frequency flexibility, audio quality, broadcast content and programming convenience.

Designed to operate under FCC Part 15 rules, InfOspot is capable of 100 milliwatts of output power, yielding a range of up to 1/2 mile even when mounted at a modest height of 20 feet above ground. The InfOspot System offers unprecedented flexibility when compared to higher powered systems:
  • No FCC license is required.
  • Any AM frequency 530-1700 kHz may be utilized.*
  • Any program content may be broadcast, including information, music or commercials.*
(*) FCC rules do not allow the broadcast of objectionable content or the use of a frequency that causes interference to other radio stations.
InfOspot's transmitter is the best designed Part 15 transmitter ever manufactured; and the results are evident – a full quality broadcast signal, which is listenable on vehicle radios with excellent loudness and range.
Broadcast Options
Available software allows you to create, edit and store audio files on your PC or laptop. You may also substitute alternate live or recorded audio sources of your choice to customize your InfOspot system.
Antenna Positioning
The gravity-mount flat-roof stand with mats and mast is the most popular antenna mounting option.
Audio Quality
InfOspot is the first system of its kind to provide the convenience of program control across both an Ethernet network and by USB/flash drive. The InfOspot digital message player operates on standardized MP3 audio files that may be processed for optimum broadcast quality and loudness. The resulting broadcast quality is unmatched.
