HAMEXAM(1) General Commands Manual HAMEXAM(1) NAME hamexam - Study guide for USA FCC amateur radio (ham radio) license examinations. SYNOPSIS
hamexam [option] DESCRIPTION
hamexam presents questions in random order from the selected question pool, and terminates when all questions have been answered correctly. The session may be interrupted with ^C, and resumed later. Some questions refer to diagrams. The diagrams for the selected question pool are displayed in a separate window using eog(1). Licenses are issued by the Federal Communications Commission (FCC), but examinations are administered by Volunteer Examiners. OPTIONS
If no pool is specified, usage, version, and help information is displayed. In normal usage, one of the following options should be specified: t Element 2, the Technician Class pool. This is the entry-level license. g Element 3, the General Class pool (element 2 is also required). e Element 4, the Extra Class pool (elements 2 and 3 are also required). q The question pool is selected interactively. FILES
A directory ~/.hamexam is created to hold the names of the questions which remain to be answered correctly. SEE ALSO
