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!
Using a well-known circuit, I show you how to build a simple computer interface so your logging software can send CW through your radio.
The logging software simulates someone using a straight key. It changes the voltage on an RS-232 pin and the electronic circuit uses a transistor as a switch, grounding the lines as though someone grounded the contacts of a straight key.
This interface will let you work a contest or pile-up using your logging software – without having to use a key or paddle.
