Radio Direction Finding System

Amateur Radio repeaters, which re-transmit radio signals, are subject to interference, both intentional and unintentional, which can render the repeater network unusable. Radio Direction Finding (RDF) systems to detect and track this interference are currently either very expensive or cumbersome to use. Many of these systems targeted for amateur radio use rely on manual readings from handheld antennas, which require lots of people and time to track frequencies and directions, which also makes it difficult to track short signals. This project aims to design a Radio Direction Finding system that uses three stationary receivers to track interference signals across Monroe County. Each receiver's frequency will be able to be updated and controlled by a single user through a front-end website. After locating the source of the interference, the location of the signal will be displayed to the user on a map. This system will cover the VHF and UHF radio frequency spectrum, including ham and commercial frequencies.
