Help!!! My Electronics Project Doesn’t Work… AGAIN! 10KHz – 255MHz RF Signal Generator

This video is kindly sponsored by PCBway. Please give PCBWay a try for all your PCB needs. https://www.youtube.com/c/PCBWay

Building Electronics Projects is not only great fun, a good way to practice your soldering skills and a method to build cheap test equipment you could not otherwise afford… it is also a very good way to learn electronics repair when the original documentation was not clear or you want to substitute some component because you don’t have the original one. In this video I try to build an RF signal generator. There will definitely be a part two…
