Questions

How big is the AMSAT SDR PCB?

It measures 92 × 92 mm and has 12 copper layers, 1.57 mm thick.

What parts does the AMSAT SDR use?

634 parts, built around the SKY13588-460LF, EP2K1+, LFCN-1000+ and LFCN-5850+. 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 AMSAT SDR KiCad files?

From the WA1CYB/SDR_Gen2 repository on GitHub, at the commit this page was made from: the board is AMSAT_SDR.kicad_pcb and its schematic AD9361-sheet-1-page6.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the AMSAT SDR design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
