We can't see the stars with our eyes during daylight hours because all the sunlight bouncing around in our atmosphere drowns them out. The sunlight makes up for this offense by turning the sky a pretty blue color.
Radio telescopes don't observe visible light. They observe other frequencies of electromagnetic radiation. These other frequencies don't bounce around in our atmosphere like visible sunlight, so as long as the radio telescope isn't pointed directly at the sun, the sun doesn't drown out the signal.

Like linlyons said, radio waves are not the same at light waves.
It doesn't have to be light or dark to receive them-- if they did your AM/FM radio wouldn't work at certain times of day either.
