How do you know what the incoming signal is such as RTTY, PSK31, Olivia, ect.? All I see are just random letters with a few numbers and symbols. I have not see a real word yet.

Knowing what frequency you are often often will tell you what you are hearing. Different modes are usually confined to specific frequencies.
If you are on 14.070 USB for instance, then the signals you are hearing ther are PSK31. Here is a link to some sound files to help you identify what you are hearing. Digital Modes Samples |
