ARLB005 Amateur Operation in 3.45 – 3.5 GHz Segment Must Cease by
April 14, 2022

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 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.

DA 22-39 can be found online at,

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 responding to H.R. 5378, the
Spectrum Innovation Act of 2021, before the US House Commerce
Communications and Technology Subcommittee.

A chronology of actions responding to amateur access on the 3.5 GHz
band can be found on the ARRL website at, .
