1. Overview and Purpose

ScannerFreakDB is a Python-based database application built to log, organize, and manage radio scanning information. Most off-the-shelf logging tools are either too generic or too rigid, making it difficult for hobbyists and professionals to track detailed frequency data. ScannerFreakDB is designed to fix this by providing a customizable and easy-to-use solution for radio enthusiasts—whether focused on ultralight DXing, UHF monitoring, or general scanning.

With ScannerFreakDB, users can quickly store, search, and categorize frequency data, making it a long-term, flexible tool for anyone serious about scanning.
