From the project
Modular learning system for radio electronics
Project Yamhill is the successor to the Willamette Transceiver, also known as the qrp-l Group Project. The purpose of this endeavor is to provide a platform to learn about radio electronics at a system level. Modules that correspond to the blocks of a block diagram will be the basis upon which different types of radio designs will be created. A modular 3D printed backplane will be the chassis, user interface, and power supply for the radio experiments. The desired goal is to have a high-performance CW QRP transceiver at the end of the main project run, however there would be the capacity to…
