From the project

Controller for High Power RF Power Amplifiers based Raspberry Pi Pico

Reading and District Amateur Radio Club(RADARC) are working together on a number of collaborative construction projects. This one is to design and build a Modular PA controller for High Power (1kW plus) semiconductor Power amplifiers. This prototype implementation is targetted on the High Power HF PA Modules from W6PQL :
