Is there a time difference if I broadcast satellite live?

A. 1

There seems to be no lag at the speed of 3 x 10^8 m/s radio wave itself, which is the speed of light in the atmosphere.
But the actual speed seems to be two to three seconds apart.
For example, when you show the weather on the news, you talk to a reporter live, and when an anchor calls a reporter, you talk a few seconds later.

There's a few seconds difference.
I think the reason is probably because it sends radio waves back to the satellite after receiving it.
It travels at the speed of light in the atmosphere, but passes through the ionosphere when shot by satellite.
Because if you're propagating through an ionized gas like the ionosphere, the rate at which the wave's energy is transmitted is a little slower than in the atmosphere.

There is some. There's a difference between broadcasting companies in Korea, too
