Yeah I have once read somewhere that the sun's radiation can be a cause of radio frequency interference. The same way auroras like the northern
lights cause such disturbances. Also, electric power transmission lines (especially the huge 500kv ones) that emits EMF are said to cause disturbances
to electronic devices, particularly radios, cable tv's and internet. Learned that when researching factors that depreciate residential real estate
property values.
Maybe this link could help:
"A Smarter Approach to Resolving Power-Line Noise"

If those things can be ruled out, then perhaps that's when the "fun" starts lol
