With the ever-shrinking band of available wireless channels for RF wireless microphones, wireless in-ear-mics, and personal listening devices, what does the church need to know in order to plan well? I’d love a Laymen’s overview of the “problem” with RF, and some practical insights, tips, tricks and best practices for how to overcome or prepare well for the ever-changing spectrum changes. Is that wired mics wherever possible? Are there specific bands that are safe? IS there data, info, or places that people can stay informed on this topic? etc.
