What are the rules regarding a business setting up an FM transmitter on top of a billboard that plays a loop of commercials?
A local car dealership has a billboard that says "tune to 105.1FM". Then on that frequency is a continuous loop of their employees making commercial announcements about the dealership.
The FCC Database has no license for this site. Also LPFM rules clearly state "These stations are authorized for noncommercial educational broadcasting only (no commercial operation)". The reach of is FM signal is 1/3 to 1/2 mile while in the car. Is that low-power enough to fall under Part 15 rules?
Is this an illegal operation? Would the responsibility fall on the billboard owners or the business engaging in the advertising? This is new and no other businesses have done this previously.
