Are Your Wireless Mics Being Stepped On?

A common source of interference for our wireless mics comes from our local television broadcasting stations. If you have a wireless mic that was working just fine, but that recently has started to make unexplained radio frequency interefence noises, check this chart to see if maybe one of your local TV stations is broadcasting on a nearby frequency. If you see a conflict, contact the manufacturer of your wireless mic system for advice on how to solve the problem. If there truly is an interference problem, they may be able to change the frequency to one that will work in your area.
