It does not get any simpler than this project but if you have a FTDX-3000 in your shack connected to an amplifier or external antenna tuner you will not build a more useful tool. This little push button switch will force the FTDX-3000 to output a CW signal at any power level between 10 and 100 watts for tuning up your amplifier or tuning up your antenna with your antenna tuner. Once the switch assembly is finished and connected to your FTDX-3000 simply set the following menu items on the FTDX-3000 and you are in business.
Construction of this project is non critical. As with all my projects I enclose a parts lists and information on the parts I choose to use. You may find parts cheaper or already on hand. I have included a mechanical drawing if you want to build it exactly the same way I did. Most importantly have fun, take some pride in your project and learn something. If you have any comments or questions drop me a line.
