Many excellent educational resources are available online by individuals and organizations. Below are a few links that may be useful to those interested in acquiring a new license or upgrading their current classification.
Testing with instant feedback for your answers at the QRZ Practice Tests for amateur radio exams are free and open to the public. No previous or existing amateur license is required to participate.
Please note that anybody can have an account on QRZ. If you are not yet a licensed amateur, simply choose a user name of your liking when you are asked to register with a callsign. Once you have obtained your license, QRZ will change your username to your new callsign.
Note: You do not need to be a licensed ham to become a member. Registration is necessary so that we can remember which test questions you’ve taken and how best to study.
Some great videos by David Casler.
The YouTube channel is called “Ham Radio Answers.” The channel includes videos for Technician, General, and Amateur Extra training.
