Exam-prep jepperdee Technician-class Edition Produced by Bob Raffaele, W2XM

Slide 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. Back 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. See last slide for a diagram or contact w2xm@arrl.net.
