How many operator/primary station license grants may be held by any one person?

The FCC permits an individual to hold exactly one operator/primary station license grant. This single license authorizes you to operate on any amateur band allowed by your license class, using any permitted equipment. Unlike some commercial or broadcast radio services that require a separate license for each physical transmitter location, frequency, or tower, your amateur license travels with you. Whether you are operating from your primary residence, a vehicle, or a vacation home, your one primary license covers all of your amateur operations.
