Oh man, you sent a CQ into the abyss and the abyss asked you for your contact card, there's no saving you anymore.

Yep, he's probably started cheerfully doodling Smith charts by now ...

(I used Smith charts a couple of times in school, but did not inhale.)

P.S.

Just hit search for 'Amateur Radio "Extra" license curriculum', and it's impressively comprehensive, at least from the first hit, a nice PDF at http://www.arrl.org/files/file/Instructor%20resources/Tiley,...

(it features Smith charts at page 109, and at 118 ends with a full page blank chart :)
