filed flight plan question
 

Looking at a SWA flight plan from kcle - klas. ( amrst1 amrst wwv115 wwv gsh j60 DW hbu j146 dvc grnpa1 ). question is : what does DW represent ? thanks ahead

Could it be DVV - Mile High VOR

I looked at the enroute chart, and it probably is Iowa City VOR (IOW), which is where J60 and J146 meet. Must have been a 'typo' by someone--- , I guess if one merges the 'I' and the 'O', you may end up with a 'D'. Was just curious as to whether there was somethin' out there I needed to know about.--Thanks

After rechecking, it is DVV, . I must keep in mind that back to back 'V's, can look like a 'W'
