Here is how the guessing is supposed to work (BTW, it applies for all 
zones, not only US stations):

1/ Search if the station has been worked on another band
2/ If not found, search is the CQWW.DTB file (which contains all current 
SCP file stations, and US zone is extracted from the current FCC database).
3/ If not found, search in the CTY_WT.DAT, if present (or CTY.DAT if 
not) exceptions.
4/ If not found, take the default country zone

Thus, if you want to modify the behaviour for W5, W6 etc... you must 
modify the current CTY_WT.DAT. BTW, Mike F5IN already patched a previous 
CTY_WT.DAT to add (among others data) these exceptions. You can find it 
here :

(Note : this file is *NOT* up to date with the current CTY.DAT).

Hope this helps
