[RTTY] HF Channel Simulators

[Kok Chen]

The following URL is the paper by KC7WW on his HF channel simulator.  
If you scroll down a bit, you can find a link to a Linux implementation 
(by OH2BNS).

Remember that these are just models of the behavior of the ionosphere.  
What you see in practice may be much more complex, but to paraphrase 
Einstein, "God may be complex, but he is not malicious."
