Questions

How big is the AM Receiver PCB?

It measures 118 × 50 mm and has 2 copper layers, 1.58 mm thick.

What parts does the AM Receiver use?

95 parts, built around the SA612AD/01, 74HC74D, 74HCT4046AD and BC547. 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 AM Receiver KiCad files?

From the TomBrown576/PCB-Design repository on GitHub, at the commit this page was made from: the board is AM Receiver/AM Receiver.kicad_pcb and its schematic AM Receiver/AM Receiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the AM Receiver design in my own project?

Its repository states no licence, so its author keeps all rights: ask TomBrown576 before reusing the design.
