FLDigi: Decode HF Digital modes with no cables and maybe no radio

I heard  a few people talking about a program called FLDigi.  So I thought I would see what it’s all about.

The good news is that FLDigi runs on lots of platforms – FreeBSD™; Linux™, OS X™ and Windows™.  The better news, if you just want to listen/decode the digital modes, is that you might not even need any messy connections between your PC and your radio.  And, if you are really clever, you might not even need a radio.  So, “in the best of all possible worlds”, Dr. Pangloss, you can decode real-time digital activity on the HF bands without even having a radio.  Imagine that!
