K7QO issues a QRP kit challenge

Gang,
I am teaching a live CW course using my CD. Two weeks into the course.
About to get to the sending part. So, looking for several ways to get 27
students on the same page. Has to be cheap, they only paid $10 for the
course which goes into the club treasury and I don't charge a dime, as
I don't want to lose any one due to placing a hardship on their budget.
In 2002, Dave Benson K1SWL, came out with the Rock Mite. What?
