On April 14, amateur radio transmissions must stop in the upper 3.45–3.5 GHz segment of the amateur secondary 9-centimeter band, per FCC order. Secondary operations may continue indefinitely in the rest of the band from 3.3–3.45 GHz.

The FCC announced in January the results of an auction for the 3.45–3.55 GHz band.

This is one of the reasons the American Radio Club is setting up a Spectrum Defense Fund to protect our valuable amateur radio spectrum!
