Go to the Ratings link at the top of the page here on R-I and you'll see the latest ratings posted for various markets. Click "See all markets', then scroll down to market # 193 for Cape Cod. However, the latest ratings posted for Cape Cod are for 2008 so they aren't updated yet.
Worcester, on the other hand, is updated for Spring 2009 with WSRS leading the pack very handily, doing twice what WXLO is doing locally. WXLO is #4 with two Boston stations between WSRS and WXLO. I assume it's ok to post the numbers since it's taken right from the R-I list.
Locally, WSRS all the way; WXLO down bigtime from a year ago; 100FM the Pike holding fairly steady; WTAG down alot; WVEI, WCRN holding down the basement; Oldies 98-9 (WORC-FM) barely treading water:
