Filter tester
About the Filter tester PCB
Filter tester is an open source PCB design by alanmimms, published on GitHub under the MIT license. It is a 6-layer board measuring 90 × 60 mm, with 62 components from 23 distinct parts.
Other key parts include the AS183-92LF. By type, the board carries 21 capacitors, 18 inductors, 10 ICs, 10 resistors and 3 connectors.
It belongs with the rf & radio and displays & leds designs in this gallery.
From the project
Fork of NexRig to build just the receiver part of the project to get started.
NexRx is an ambitious open-source project that reimagines how we interact with ham radio receivers. Instead of the knobs, buttons, and menu diving that have defined radio interfaces for decades, NexRx presents a browser-based interface built around a revolutionary concept called "setboxes."
Think of it as bringing ham radio into the modern computing age - where your radio's interface is as flexible and powerful as the software on your computer, but still maintains the real-time performance demands of RF communication.
