2. Exam-prep Jepperdee: 2014 Tech Edition …a game to help prepare contestants and audience for the entry-level ham exam produced by Bob Raffaele, W2XM

3. This game is to be played in the PowerPoint “slide show” mode. Operation of the game is almost intuitive, and you can make up your own rules. Each numeric point value on either game board is a hyperlink which reveals a question. Advancing the game one slide past the question (by clicking the screen) displays the answer. “Done” on the answer slide returns you to the game board. “SFJ” (clickable) stands for “semi-final jepperdee” and “FJ” (also clickable) means “final jepperdee;” clicking anywhere on the screen reveals the final- or semi-final-jepperdee question. There is one daily double on each board; click on either “daily or “double.” For most fun, appropriate hardware (lights, push- buttons, sounder, lockout circuitry) should be used. A diagram is available from the author.
