57 parts, built around the AD8307AN and TL072. 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.
From the SmittyHalibut/HF-QRP-ServiceMonitor repository on GitHub, at the commit this page was made from: the board is hardware/RF Deck/RF Deck.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
