The FCC has established April 14, 2022, as the date by which amateur radio
transmissions must stop in the upper 3.45 - 3.5 GHz segment of the amateur
secondary 9-centimeter band. Secondary operations are permitted to continue
indefinitely in the remainder of the band, 3.3 - 3.45 GHz, pending future FCC
proceedings.

On January 14 the FCC released[1] DA 22-39, which announces the results of
Auction 110 for the 3.45 - 3.55 GHz band. Release of this notice triggered FCC
rules adopted last year requiring that amateur radio operations between 3.45
GHz and 3.5 GHz cease within 90 days of the public notice.

In October 2021, ARRL President Rick Roderick, K5UR, urged Congress to direct
the FCC to preserve Amateur Radio's secondary use of the 3 GHz band in a
written statement[2] responding to H.R. 5378, the Spectrum Innovation Act of
2021, before the US House Commerce Communications and Technology Subcommittee.

A chronology of actions[3] responding to amateur access on the 3.5 GHz band can
be found on the ARRL website.
