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.

Since the last post, I had gotten involved in a Facebook group with a focus on the mcHF transceiver. As well as being a great forum for sharing knowledge and experiences, it gave me the opportunity to get a very nice case in a group buy organised by one of the members. The case is 2-part design, which is easier to work with than the one I bought  previously. It also comes with buttons, a speaker and very nice machined aluminium knobs.
