In July of 2011, television stations switched over to digital broadcasting. Consequently, many wireless mics were required to stop transmitting on the old TV channels. So, does this include your wireless mics? If so you may be in violation of FCC regulations, and soon you will start having digital interference bursts over your sound system, since almost all mics made in this range were analog. (Think fax machine or modem noises.)
Maybe your church upgraded in 2011 or later, but now things are uncertain again. The FCC is moving even more channels around in 2016. The good news is there will be a 39 month period for unlicensed users to stop using wireless mics after the changes are made. However, you may need to replace your wireless mics in the next four years.
Now the good news! The FCC has been lobbied by major wireless mic makers and is making promises about creating some safe spectrum for wireless mic users.
Update: As of November 2016, the second part of the spectrum auction continues to drag on… However, this isn’t so bad, it just means that you’ll get more life out of your current wireless systems while the FCC does it’s thing.
