[Elecraft] K3 CW and RTTY tones

[goldtr8 at charter.net]

Dear All,

When operating CW or Rtty there is a split tone that you have to know 
about.  I have been reading on the HRD forums to figure this out to get 
the software set up correctly.  I know it has something to do with 
carrier supression, but it just does not make sense to me.

So the more I read there the more confused I become.  I have also tried 
google searches but I still have not figured it out yet.

So if someone can direct me to some reading sources to help me 
understand this I would really appreciate it.

Thanks
Don
