Questions
How big is the Swr meter PCB?
It measures 65 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Swr meter use?
70 parts, built around the PE4259-63, TSR 1-2450E, AD8307ARZ and AD7991YRJZ-0RL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Swr meter KiCad files?
From the F6ITU/vswr_meter repository on GitHub, at the commit this page was made from: the board is swr_meter.kicad_pcb and its schematic Documentation/swr_meter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Swr meter design in my own project?
Its repository states no licence, so its author keeps all rights: ask F6ITU before reusing the design.
