The goal for any of these lessons is for the student to read the material, look at the Power-point presentations, view the U-tube videos and review the Industry Canada exam questions. There may be additional information given.
If you are attending a radio course, then it is expected that you will have done all of these before attending the class. The idea is , at the beginning of the lesson, the instructor will clear up any questions you may have and then continue on with hands on experiments, show and tell, operating radios and setting up stations, building antennas etc.
