Extra class license questiuons

Many people thought that the internet would kill amateur radio, but it actually helped it grow, by increasing the number of things you can do with a ham radio license, and by making the information on how to do it accessible to all.

There are probably millions of people out there who had never heard of ham radio until they learned about it on the World Wide Web. In order to pursue the hobby of ham radio, a person needs a license from the federal government.

There used to be six different kinds of licenses, but a while back the licensing process was streamlined, and now there are only three — Technician, General, and Extra. Technician is the entry level license. General is the intermediate level and may be taken by people who have passed the Technician exam.
