DIY "Wonder Loop" QRP Antenna

I am a member of a group on Facebook that shares and discusses antenna designs, usually of a portable nature. Recently the topic of the WonderWand WonderLoop antenna came up, particularly how expensive it is relative to its apparent complexity. A number of members had posted pictures of a torn-down control box, and it really seemed to contain little more than a transformer wound on a mix-6 toroid and a variable capacitor.
