So good to hear Wayne telling his lifelong QRP portable story, it's been a four decade obsession to halve, halve, and halve again, leading to the amazing KH-1. Ive followed W7ZOI and Wayne 's designs, and many others, over this time and built a number of them, so interesting to hear the back story. Thanks for recording and sharing with the ham QRP world!
