WNEW-FM, which had been rated around #30-something in the last couple of monthly Washington ratings, has dropped off the list completely.
Arbitron has changed its reporting system, so that stations that don't subscribe to the ratings in each market are off the published list. That's why most Baltimore stations aren't showing up in the Washington ratings at this point and visa-versa. But that doesn't apply to WNEW-FM.
The other CBS-owned stations in the DC market are listed, including Latin Hits WLZL, which left 99.1 for 107.9 to make way for WNEW-FM. If anything, you'd think CBS would want to make sure WNEW-FM shows up in both the Washington and Baltimore books, since its signal covers Baltimore better than rival WTOP.
