The General Class license is the second of three US Amateur Radio licenses. To upgrade to General Class, you must already hold a Technician Class license (or have recently passed the Technician license exam). Upgrading to a General license–which conveys extensive HF privileges—only requires passing a written examination. Once you do, the entire range of operating modes and the majority of the amateur spectrum below 30 MHz become available to you. The FCC grants exam Element 3 credit to individuals that previously held certain older types of licenses.
