Earth Moon Earth

One of the things that has always interested me is doing an Earth Moon Earth contact. I remember trying to listen for my own echo by pointing the direction antenna from my school at the moon and bouncing an FM voice signal off of it (It takes seconds for the light path to connect back up, thus it is common to hear your own echos off of the moon). I wasn't successful.

An EME contact, simply put, is one where you use the moon to bounce signal off of and talk to someone else on the ground. This is often considered the pinnacle of VHF communications, and can in fact allow for worldwide communication, but it can be a bit tricky to perform. I am going to borrow some information from my elmer in this area, Paul, K4MSG, and specifically his article entitled "EME on a budget". This will include some of my own research on the subject as well.
