README.mdNOAAmp - Reliable Signal Gain for NOAA Reception
By: @Scooter Y
What it is?
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.

Questions
How big is the Noaa PCB?
It measures 28.5 × 20.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Noaa use?
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.
Where can I download the Noaa KiCad files?
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.
Can I use the Noaa design in my own project?
Its repository states no licence, so its author keeps all rights: ask scooterthedev before reusing the design.
