Not everything below 28.200, George.  W6WX/B at 14100 kc and 21250 kc  
are exceptions that prove the rule which you mentioned.

The approved stations not only are allowed to operate on 14.100 around  
the world, that particular window (1 kc wide) is even a guarded IARU  
frequency for beacon use only; although you can hardly notice it  
during RTTY contest weekends.
