[Elecraft] unequal tone power output in FSK

I agree with Dave. If what you were seeing was due to passband ripple, 
choosing a different RTTY pitch should make a difference. I don't 
believe it does. Not only that, but if it were passband ripple, it would 
affect AFSK A the same as FSK D.

My solution to this is to use AFSK A - it has almost all the same 
features as FSK D, but produces cleaner output.
