InfOspot ̶ originally marketed as the Talking House AM radio transmitter system ̶ is the first professional, license-free radio station available for government, nonprofit and individual applications. It is the most 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 up to 100 milliwatts of power, yielding a range of up to 1/2 mile when mounted 20 feet above ground. The InfOspot System offers unprecedented flexibility and affordability when compared to higher powered, licensed systems: (1) No FCC license is required. It is certified under FCC Rules Part 15.219. (2) 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.) (3) Any AM frequency 540-1700 kHz may be utilized. The frequency is easily changed using front panel controls. (4) InfOspot Systems utilize the most trusted, time tested Part 15 Transmitter to generate the broadcast signal. (5) The system’s Range Extender Outdoor Antenna and Tuner (ASIN B07TLNS2DF) may be mounted at any height above the ground, due to the exclusive coaxial Transmitter-to-Antenna linkage. (6) Integral 5-minute / dual message digital voice recorder / player for simplified message creation. (7) Security key prevents unauthorized transmitter control tampering.
