MV,
How about our own Sun? I'm not a radio addict, so I can't name the exact
frequencies now, but any short-wave radio or ham-radio operator can let you
listen to the radio noises of our nearest star. You do not need a dish
antenna for these nearby signals; any antenna (that can accommodate these
frequencies) will do.
Radio astronomers have "mapped" the sky at various radio frequencies, and
the radio star charts look rather different from the visible light star
charts.
Cheers,
Red

These are pulsars. Dont you have a normal star in your basket? I'd
love to hear it.

cfs717,
Stars do emit radio noise, but not uniformly, all across the radio
spectrum. We are listening in a "quiet part" of the radio spectrum,
thinking that aliens would choose to send a signal where it has a better
chance of being detected.
Listen to *these* stars; click the gray arrow buttons on this web site.
It takes a minute to load each one, but it's worth the wait.

Not even a strong, regularly pulsed radio signal from outer space is proof
of ETI. We continue the search here...

We all know that it is imposibble to see a planet from other solar system
nomatter how powerfull a telescope might be.
Because the light from the Star is so bright that it cover-up the dim light
from the planet.
We also know that a Star emit radio wave.
Won't that radio wave from the Star cover-up the radio wave from the planet
where ET live?
