Thanks for your comments!
The QRP Quarterly published my article last year. It also was published in Spain with a few additions.
It’s still here online, which is nice. A few people have built similar tuners that work well, and that is what I hoped would happen.
My larger tuner works well down through 60M, and up through 15M, but I need to build some new tuners for higher frequencies and lower frequencies. When the sunspots return, great times await, perhaps on 10M with easy DX during the day.
With the virus crisis, this is a good time to stay home and build tuners and other gear for SOTA!
