Exam-prep jepperdee
Technician-class Edition
Produced by Bob Raffaele, W2XM
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” stands for “semi-final jepperdee” and “FJ” means “final jepperdee;” proceed by clicking screen until you see the next hyperlink. There is one daily double on each board; click on “Here’s the question.”
For most fun, appropriate hardware (lights, push-buttons, sounder, lockout circuitry) should be used. A diagram is available from the author.
