For Wireless Microphone Users: Information about the FCC 600Mhz Transition
Wireless microphone systems operating between 616-653 MHz and 663-698 MHz and as of July 2020 are now prohibited by law to use. The FCC auctioned these frequencies off and microphone users need to stop using systems on these frequencies. The 600MHz spectrum has been repurposed for new wireless broadband services and is no longer available for use by wireless microphones operating in this frequency range.
The end date for legal wireless microphone usage in the 600mhz frequency range was July 12, 2020.
What does this mean to wireless microphone users?
Any microphone system or component in this frequency range is now illegal to operate as of July 12, 2020. Additionally, wireless manufacturers are prohibited from repairing 600mhz transmitters and receivers.
To provide an example:
A Samson Airline 77 replacement headset/transmitter on an "N-series" frequency is now illegal to use as of July 12, 2020. However, a full new Samson Airline 77 Microphone System on the "K-series" frequencies has not been affected and is available for $299.
Note: Samson, Audio-Technica and Galaxy Audio 600Mhz Trade-in Rebate Programs have ended.

- Most (but not all) of the spectrum from 614-698 MHz has been repurposed for use by wireless services and will not continue to be available for wireless microphone use
- Wireless microphones that operate in the 600 MHz service band (the 617-652 MHz and 663-698 MHz frequencies) are required to cease operation, effective July 13, 2020.
