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
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, pushbuttons, sounder, lockout circuitry) should be used. A
diagram is available from the author.
