A method and system for detecting and diagnosing leaks and interferences in a cable network by detecting interferences through radio receivers and correlating with data extracted from the network elements. Interferences in a cable network are detected with a kit comprising an antenna, a radio receiver, a computer device, a global positioning system (GPS), and an application. The method includes moving the radio receiver within an area of coverage; receiving and recording a radio frequency (RF) measurement; detecting an interference point based on a signal level of the RF measurement; determining, with the GPS, a location of the interference point; and reporting the location of the interference point, as it is detected, to the application.
