What are possible radio beacon disturbances?

Radio beacons are susceptible to atmospheric and propagation effects that create noise and interference on the received signal. Lightning produces intense, broad-band RF energy that can flood the receiver and cause garbling or temporary loss of the beacon signal. Precipitation static arises when charged precipitation interacts with the air, creating irregular RF noise along the line of sight and degrading reception, especially in stormy conditions. At night, certain atmospheric conditions can enable distant stations to affect local frequencies through long-range propagation or ducting, leading to interference with a nearby beacon signal. Other options don’t fit as well because solar flares primarily affect higher-frequency and longer-range communications and aren’t a routine concern for typical beacon reception; general EMI can be a factor but is not as specific to beacons as the weather-related and propagation effects listed; weather radar operates on a different, higher frequency and is not a common source of beacon disturbance; power line noise is a possible local issue but is less characteristic of the described disturbances compared to lightning, precipitation static, and night-time distant-station interference.
