The Extra Class license is the highest of all three US Amateur Radio licenses. To upgrade to Extra Class you must already hold a General Class license (or have recently passed all of the exams required for a General Class license). Upgrading to an Extra license only requires passing a written examination. As an Extra Class licensee, you will have full privileges on all frequencies authorized by the FCC for Amateur Radio.
