Wiring Diagram

Here is both a handwritten diagram and text based description of the wiring for MyAwos.  The wiring is pretty simple - four components. Pi, Radio, Relay and Arduino. You do not even need a breadboard. Some WAGO 221 connectors will do the trick just fine.  

However, sometimes wiring just doesn't click for you. So if you have questions or get stuck let me know. Happy to send pictures or walk you thru the steps.

 If you use the AirSpy R2 SDR instead - just remove the Arduino all together, the AirSpy connects via USB. You can also a USB relay so the wiring is just three wires - from the Yaesu radio splitter.
