How do you hear radio waves from space?
Get a radio scanner which will receive VHF-UHF signals, preferably a single sideband model. In theory you could use an FM-only handheld radio, but a decent scanner will improve the quality of your signals. Take an old VHF Yagi TV antenna and point it at the direction and elevation you previously calculated.
How far have radio waves Travelled?
That means our radio signals could only have traveled up to 116 light-years away — creating a “bubble” around the Earth announcing we’re here. “If there are any aliens inside the bubble, they might know about Homo sapiens,” Shostak said.

How can I detect a listening device in my home?
These devices pick up the radio frequencies when the device is sending a signal. A good way to test it’s effectiveness is to use your mobile phone near the detector and dial up someone. You will hear the device beep, to confirm RF signal. This is the same result with the listening device, when detected.
Where can I check to see if my lights are out of place?
Ensure that you check light fittings, book shelves, flower arrangements, extension leads, under surfaces such as desks. pictures on the wall out of level or lampshades that are out of place. Normally a device would be placed in a location that has a clear view of the activity.
