Wireless Microphone Usage

Users of this device must cease operating on these frequencies no later than July 13, 2020.

Changes to operations on frequencies in the 600 MHz service band
To meet increasing demand for wireless broadband services nationwide, the FCC recently auctioned spectrum that had been licensed to broadcast television stations operating on TV Channels 38-51. The results of the auction (completed in April 2017) will affect the availability of spectrum for wireless microphone operation on the 600 MHz frequencies that correspond to these TV channels, specifically the 614-698 MHz frequencies. Most of these 600 MHz frequencies have been repurposed for new 600 MHz service wireless operations (specifically, the 617-652 MHz and 663-698 MHz frequencies).

There are systems still in operation that users are unaware fall in this range. The 600 MHz systems were very popular in our area for years. Some systems only have a Channel number on the screen, users don’t understand that represents a frequency range that needs to be checked if it is in compliance.
