I purchased the 40m version of the QCX kit a while back. Seeing Hans Summers (QCX designer) at the recent Four Days in May event made me very excited about this little rig so I came home and built my kit. What an awesome little CW-only radio – for only $49!
In this video, I review the QRPGuys.com End-Fed Half-Wave Mini Tuner. This is a $25 kit that will tame the high impedance of an End-Fed antenna. With this, you can deploy a half-wavelength of wire without feeding it in the middle (like you would for a traditional dipole).
Easy to build. Works great. A nice little kit for your building pleasure!
Here are the basic tools that you will need for electronic projects. It’s a great time to tinker with electronics because there are so many radios, antennas, tuner, and other gadgets available as kits. Of course, you can “homebrew” your own gizmos, too!
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!
