Yes that’s right, we’ve started on construction of the QRP Labs QDX- Despite one major challenge, that is. Check the video below for details, and make sure to subscribe to the YouTube channel for more updates, as I try not to duplicate content too much between the blog and YouTube. They serve different purposes. Thanks!

Ha. You do those tapped inductor toroids better than I do. I hate ’em! Like a pro!
My only suggestion is to go maybe 80 cm instead of the manuals 75 cm on the length of the wire (or maybe 31″ instead of 29.5″). I had to rewind the last two taps because I ran out of wire at 75 cm. And because of that I had a small kink in the wire that I didn’t notice so the 30T to 36T area of my tapped inductor isn’t quite as tightly wound as the rest because I couldn’t pull the wire through. Still fine, toroids get most of their inductance through the turns through center but if I were to wind it again I would do it slightly differently than Hans suggested.
Oddly I don’t mind making those on binocular cores though. Those are a snap for me.
So far the QDX is a very quick build but it does have a bunch of hand wound parts. I will keep looking for more of your videos. I am always interested in different ways of building to pick up “best practices”.
