Questions
How big is the Filter PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Filter use?
106 parts, built around the ULN2803A and 1N4733A. 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 Filter KiCad files?
From the profdc9/QRPAmplifier repository on GitHub, at the commit this page was made from: the board is Filter/Filter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Filter design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
