Welcome to the KF4L Learning Center
The purpose of the KF4L learning center is to maintain and improve our technical abilities throughout our amateur radio careers and provide opportunities for the development of new amateur radio operators.
The first steps in Amateur Radio
There are many different avenues one could take to get into amateur radio. The most common are test books like the ones found here. After you feel comfortable studying. Online practice tests can be found at hamexam.org. A good rule for online practice is 85% or higher and you are ready to test. Testing times and locations can be found on the Events Page. Don’t forget to bring a copy of your FRN and two forms of ID.
