I have seen ads for various microphone and IEM systems that run in the 944-960 MHz Broadcast Radio STL (Studio-to-Transmitter Link) band. This band is reserved EXCLUSIVELY for broadcasters, and you MUST have a license to use equipment here - period. This band is full of very sensitive STL equipment for radio stations, and unlike the TV bands that we usually operate in, there is a very good chance you could cause broadcasters a lot of trouble by operating equipment here. So, with that said, DO NOT BUY 944-960 MHz WIRELESS AUDIO EQUIPMENT! Broadcasters are promising to hunt down users that interfere with their operations, and they are very likely to cause you a lot of trouble - to the tune of a potential $11,000+ fine from the FCC. Discussion may commence in any of the current wireless threads. This post serves as a PSA only.
