NA1SS - Ham Radio on the International Space Station

The International Space Station (ISS) is equipped with Ham Radio to communicate with radio operators on Earth.

Thanks to the installation of new solar panels the ISS can be very easy to spot in the night sky with the naked eye.    It is the biggest man made object in space orbiting the planet at this time.

To see when the ISS will be passing overhead you can check out this web site:
