Talking To/At Aliens

A new service has been launched where you can call a premium rate number, and leave a message that will be broadcast into outer space. Recently, the Craigslist bigwig won an ebay auction to broadcast some material into space, but he paid $1225. With this new service you need only pay $3.99 per minute. Still, surely this is unnecasary, as all broadcasts will reach an indefinite distance, albeit at a reduced signal strength dependant upon distance. If an alien technology really wants to listen to my mobile phone calls, they'll have to filter out the fuzz, turn up the volume and decrypt it. But you get my drift, if you do have a legitimate reason for trying to get in touch with little green men, then just DIY.
