    Winding toroids is often "scary" for folks. Here I show how I do it. I'm no "pro toroid" winder, I do it by hand. Just like everybody else.

    This is part 2 in the journey of building the QCX-Mini for 20m. This is a fantastic radio, with fantastic instructions. If I can do it, so can you!

    Great video. The winding process was oddly satisfying! Hope the project is coming along nicely. I like your background music because it reminds me of Tomorrow Land at Disney World.

    An alternative way to check the turn count on a small toroid is to take a photo.
    Look at it on a large monitor.... or print it.
    Then mark each turn on the paper with a pen.
    A blown up photo on a monitor is also great to check solderings.

    I've been toying with the idea of building the larger QCX+---exact same circuit, I believe, but with a larger layout and enclosure. I'm investigating what kind of power output folks are getting and if they're really getting 5w out with around 13.8 volts I will probably pull the trigger.

    'Hose toroids' are ALWAYS tough to wind!

    It is easy! It just takes longer than you're planning ;-)

    At least that's what I keep telling myself

    You might watch this video by Hans about tuning up the QCX+, 5w should be possible on 20m with 13.8v.
    I have to do all his tips to mine (20m), only 2w out as initially built.

    Just make sure all the water is out and if you warm the hose in the sun first it will be much easier. I also use the absolute biggest toroids I can find, I think they're like, uh, FT-2400s or thereabouts.:eek:
