What causes radio disturbances?

Radio disturbances can be caused by various factors, including natural phenomena such as solar flares and geomagnetic storms, which can disrupt the ionosphere and affect radio wave propagation. Human-made sources, like electrical equipment, industrial machinery, and even certain types of communication devices, can also generate electromagnetic interference. Additionally, atmospheric conditions, such as thunderstorms, can create noise that interferes with radio signals. Overall, both natural and artificial sources contribute to radio disturbances.
