This project came from the idea that I needed a simple, light spectrum analyzer which could be easily interfaced to embedded applications. This design was a proof of concept which made use of an RFM22B radio module and a PIC16F690. A simple GUI was also constructed for initial testing purposes. Photos of the prototype can be seen below. Source code for the proof of concept can be found downloaded here:

The next post will contain some screen shots of the GUI in action.
