Alan, your two Youtube QRP kit videos are fabulous. The high view count for the Cub video (900+ views in 8 days) shows there is a need for them. Who knew??? Those numbers are amazing for a video that doesn't have the word "topless" in the title.
It would be wonderful if you could do a series on all the popular QRP kits. I would think the makers would be fully cooperative because the YT exposure would help them sell more kits.
My son, an EE student, and I built an Oak Hills OHR-100A QRP kit last year. While its manual is excellent for building the kit, it says virtually nothing about how the 300+ components function. A schematic is included, but no block diagram or text explanation.
I'd be happy to send you a copy of the OHR-100A manual if you'd like.
