Charlie Morris, ZL2CTM, builds his QRP rigs, the old fashioned way, starting with a paper and pencil, combining basic components to make each stage of a receiver or transceiver.  Once the radio is made, he adds an Arduino micro-controller, touch screen, and other advanced components to bring his masterpiece into the 21st century. Charlie is a prolific creator of You-Tube videos to document and demonstrate his creations.  ZL2CTM is my QSO Today.
