The purpose of this page is to allow you to determine the range at which a possible alien radio transmission, such as from Gliese 581 or SHGb02+14a, can be detected, using your choice of assumptions about frequency, antenna dish size, receiver bandwidth etc. Similarly you can calculate and model ideas for sending signals to, or receiving signals from, places like Gliese 581 or OGLE-2005-BLG-390Lb or HD 189733b or 55 Cancri. The Search for Extra Terrestrial Intelligence SETI involves using sensitive radio telescopes to search.

Very interesting tool, particularly tinkering with ELF...

A little bit confused - please be advised, not an astronomer - but will try to understand *fighting* =)

Interesting to see what happens to range at 1.42GHz :-)

Can someone please let me know how large the alien transmittor dish is. I'm not sure I can see it from here. That and the aliens havent told me how large their dish is. I'm also not quite sure what wattage they are using as well.

At what Signal/Noise ratio is S@H software able to detect something and what is the temperature of the ALFA receiver?
