From the project

Based on design by W7ZOI in 1998 QST

This repository contains a complete KiCad implementation of the famous W7ZOI Spectrum Analyzer design, originally published in QST magazine. The W7ZOI spectrum analyzer is a well-regarded amateur radio test instrument design that provides a cost-effective solution for RF spectrum analysis.

The W7ZOI Spectrum Analyzer is a superheterodyne spectrum analyzer designed for amateur radio applications. It provides frequency analysis capabilities across the HF and VHF bands, making it an invaluable tool for antenna analysis, filter characterization, and general RF measurements.
