Megjegyzés
A 'lib-table' fájlok hozzáadják a kapcsrajz szimbólum és rajzolatokat tartalmazó fájlokat a könyvtárak közé. Amennyiben ez mégsem történik meg, ezt manuálisan kell megtenni.

Questions
How big is the 70cm preamp PCB?
It measures 41.8 × 13.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 70cm preamp use?
15 parts, built around the PGA-103+ and SF2446E. 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 70cm preamp KiCad files?
From the simonyiszk/70cm_preamp repository on GitHub, at the commit this page was made from: the board is 70cm_preamp.kicad_pcb and its schematic 70cm_preamp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 70cm preamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask simonyiszk before reusing the design.
