HRWB055 4-Port Coax Relay Project Design

George KJ6VU takes us through a thorough deep dive of the design of the 4-Port Coax Relay Project.  We talk about the five major sections of the project - RF circuit switching with relays, control via PIC Microcontroller, the power supply, the user interface, and serial communications.  Each section provides a reference design that could be leveraged in other projects.
