W3BBO to the rescue! Once again.

 I mentioned in the previous post how it's QCX toroid time. I had mentioned to Bob W3BBO that as excellent as Hans Summer's assembly manuals are - they differ from Elecraft in one important way.

When you're ready to wind a toroid in an Elecraft kit, they generally start off the step with something like this "Cut off a 12 inch piece of the supplied magnet wire". In the QCX manual, Hans just gives you the toroid nomenclature and the number of turns. I'm not a rocket scientist - how much wire do I need without cutting too much and wasting some - or cutting it too short and REALLY wasting some?

Bob W3BBO had the answer, as always.  Go to W8DIZ, Diz Gentrow's Website at kitsandparts,com. He has a toroid page complete with winding info.

Take for instance - L4 on the QCX 40. It's a T37-2 toroid and you need to wrap 16 turns on it. Simply go to https://www.kitsandparts.com/xtoroids.html and you will see that you need a 10 inch length of magnet wire. Easy peasey, lemon squeezy! 

This is the stuff you automatically know when you are a home brewer par excellance, which Bob W3BBO is and I am obviously not. Thanks again, Bob - for pulling my fat out of the fire. In thanks, I will pay it forward and pass your tip to others out there who may need it. (I'm probably alone in that regard).
