Broadcast Television Spectrum Incentive Auction Finally Concludes
FCC Auction Update – January 2017

The 600MHz band auction, which began last spring, has finally come to a long awaited conclusion. 

On April 13, 2017, the FCC published the final CRPN, (Channel Reallocation Public Notice), which outlines the move of the TV stations in the upper 600MHz spectrum to new channels below 608MHz in a process called "repacking”.   Some stations chose to go off the air (for a cash payout), and some will begin sharing a channel with other stations.  We now know not only how much spectrum is to remain and where the "duplex gap” and guard band will be (see diagram below), but also the exact channel lineup your city or town is going to end up with.

This news is heartening. Much less spectrum is being lost than we had originally feared. The original goal of the auction, had it been successful, would have taken away 126MHz of the UHF spectrum. We are grateful that the final loss of only 84MHz will be much less harmful to the operation of wireless microphones and other wireless gear.

The final Channel Reassignment Public Notice triggers a 39 month "clock” during which the TV stations must either go off the air or move to their new assigned channels. This will proceed in 10 “phases” beginning this July and continuing until October 2020.  Once the new wireless services begin operation in a particular city on their assigned channel, wireless operation in that channel must cease.  So the changeover will be different for every city.

As we have in the past, we are happy to offer re-blocking service for any eligible affected units, at approximately 1/3 to 1/2 the cost of new. Please consult the re-blocking price list for further details. For any questions about re-blocking or to schedule your products for this service, please contact us at 800-821-1121 or This email address is being protected from spambots.

We will continue to update this page as news from the FCC is published.
