I finished building the 40 meter version of the Oak Hills Research 100A QRP transceiver. I also added the internal keyer.
In this video, I share my final thoughts about the build and the radio.
Summary: It’s a great radio and I encourage you to build one. The documentation could use some tweaking to make it easier to understand a few of the more confusing steps. However, I built it without help and it worked right out of the gate. If I can do it, you can do it!
