Huh? I'm no expert in microwaves, but I don't see how sunlight can be
the cause of noise in a lower part of the EM spectrum, unless the
effect is caused indirectly.

Frank,

Do a Google search on blackbody radiation. The sun radiates far more than
light. There is uv (I'm sure you're aware), plus microwave, plus lower
frequencies as well. The temperature of the body determines where the bell
curve of frequency of radiation will peak, but there is a heck of a lot of
other radiation too.

Best regards from Rochester, NY
