In the QST May 2021 edition, page 30, there is an article about constructing a TDR project. I made a home brew circuit board and put it in a cabinet and it worked great! Then I decided to make a printed circuit board project and order it. Now I know what a Gerber file is. Filling in the PCB and putting it in the cabinet this also works great. So now I have one working prototype board and 2 bare PCBs that work. So, if someone would like to make one of these projects and use one of these items send me a message.
