Noaa is an open-source printed circuit board by scooterthedev, from the scooterthedev/noaa-ant repository on GitHub. It is a 2-layer board of 28.5 × 20.8 mm with 18 parts on 22 nets, routed with 73 tracks and 26 vias.
It is built around the GALI-84. Its parts include 6 capacitors, 3 resistors, 3 connectors, 2 inductors and 1 IC.
NOAAmp is an extremely small PCB- only 28.5x20mm in size, that is capable of taking in an SMA input signal from an antenna like a custom built QFH antenna, and amplifing the signal to be sent to a device like a RTL-SDR to be viewed. This PCB will only work for 137MHZ since that is the freq of the NOAA-19 satellite that I am targeting.
This PCB + Enclousure is done, but you can view my journal throughout on JOURNAL.md.

It measures 28.5 × 20.8 mm and has 2 copper layers, 1.6 mm thick.
18 parts, built around the GALI-84. 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 scooterthedev/noaa-ant repository on GitHub, at the commit this page was made from: the board is noaa.kicad_pcb and its schematic noaa.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask scooterthedev before reusing the design.
