The Sun generates electromagnetic energy in every frequency as it fuses hydrogen to helium in its core. Electromagnetic energy is, depending on the frequency, light, heat, radio, X-rays, gamma rays, and everything in between. So the Sun is continually generating radio energy and radiating it out in all directions.
We can receive those radio signals from the Sun and other stars; that's the basics of how "radio telescopes" work.
But sometimes, the radio signals from the Sun can interfere with the radio signals that we ourselves generate, and this can cause disruptions in our own signals. This can especially be an issue when the Sun has emitted a "Coronal Mass Ejection" which strikes the Earth, causing a "solar storm".

Why does radio and satellite reception deteriorate when the sun goes down?
All satellite equipment, whether it be for communications, TV or radio, operates on its own specific radio frequency to communicate with the satellite. Light also gives off a radio frequency. "White light" which is what the sun gives out, is a full spectrum frequency. This means that every radio frequency there is, the sun is emmiting. So for you, when the sun goes down, the satellite which your radio equipment gets its signal from is probably in the path of the sun. Since the sun's rays are so powerful it inteferes with the satellites signal to your radio equipment. Let me know if I am right on this, you have XM radio. I am a satellite communications systems operator/maintainer in the US Army. Just curious because the XM satellites are geostationary which means that they are constantly in the same place in the sky in relation to the ground. You probably wouldn't have this problem with Sirius radio because their satellites have a highly elliptical orbit which means that there are multiple satellites moving over the western hemisphere where there are always two moving across the skies over North America. Since there are two always in the sky in different locations, if one was in the suns path, your radio would receive its signal from the other. Just as a little satellite humor, we sometimes have problems with our equipment when we try to locate the satellite in the sky. If the satellite is near the sun, our dish sometimes locks onto the sun. A couple of times I've seen when the sun crosses the path of our signal, the dish will start following the sun and we lose communications.
Why do robins spread their wings in the sun?
To absorb the heat coming from the Sun, or it could be a signal to its mate.
The sun's revolutions cause the seasons.?
The sun's revolutions cause the seasons.
What two things cause the seasons to change on earth?
There are two things that cause it which are the earths orbit and thetilt of the earths axis.
Is the sun the main cause of rising and falling tides?
North moon is the main cause because
Which parts of the sun interfere with our radios?
The sun's corona and chromosphere can interfere with our radios. These regions of the sun emit radio waves that can sometimes overlap with the frequencies used by radio communication on Earth, causing disruptions and static in radio signals.
Why do auroras mess up my radio signal?
Auroras are radio frequency emanations from the violent solar flares that occur on the SUN. Visibly these auroras can be seen visually as wavering shows of light in the far north sky. These flares can also cause momentary much higher levels of radio frequency noise which can and does cause interference to Radio & TV communication systems frequencies used here on Earth.

What is the burst of energy from the sun called?
The burst of energy from the sun is called a solar flare. These are sudden releases of magnetic energy on the sun's surface that can cause disruptions to technology and communication on Earth.
Was there ever been a solar flare?
Yes, solar flares occur periodically on the Sun. They are sudden, intense releases of energy that can cause disruptions to satellites, radio communications, and electrical grids on Earth. Scientists monitor these events to better understand and predict their impact.
What is a sudden increases in brightness of the chromosphere of the sun?
A sudden increase in brightness of the chromosphere of the sun is known as a solar flare. These are intense bursts of radiation that happen when magnetic energy that has built up in the solar atmosphere is suddenly released. Solar flares can cause disruptions in radio communications and satellite operations on Earth.
Can the sun cause an EMP?
It doesn't cause an EMP. However, sunspot activity can interfere with radio transmissions.
1995 Pontiac Sun fire the left turn signal does not work the right turn signal does?
Check the bulbs. A failed bulb can often cause the signal to stop working on that side.

Radio reception improves after sunset-why?
If you mean FM/AM radio: Radio reception is based off the bouncing of radio waves off of the upper atmospohere and ionosphere. But in the daylight, the sun causes molecular turbulence in those layers like photodissociation and infrared absorption. Imagine trying to look in a liquid mirror that has a lot of turbulence vs one that is rather stagnant. Sunlight makes the "mirror" of the upper atmosphere and ionosphere turbulent while in comparison the night sky is a more stagnant "mirror" Particularly, radio stations switch to low power mode some point after dark because of the substantial increase in transmission-reception ability. ---- If you mean radio astronomy: Your question is better stated, "why does the signal-to-noise ratio improve after sunset" where "improve" means "increase". Though it is not as dramatic as the visible or infrared emissions, the sun is a strong radio source. As a result, if we are looking for radio signals that are not the sun, then the sun is considered to be part of the background noise. Then after sunset, this noise source is propagating through the earth and not directly into the radio telescopes. As a result, the amplitude or level of noise has decreased and the signal has remained mostly the same and thus the signal-to-noise has increased by dividing by a smaller noise. signal-to-noise is literally "signal divided by noise".
Why do radio's fuzz when they lose signal?
They are picking up the background radio static noise. It has many sources: bad electric motors, the sun, stars, even the original big bang 3K radiation.
Harmful effects of radio waves?
Radio waves aren't harmful at its usual pattern of operation. They are harmful only when a strong signal is close to a person. It can cause cancer and other problems. Radio waves may also cure. All waves have different results.
