@DavidEduardo - I was looking at the DC monthlies and saw WWUZ from the Fredericksburg metro and WWEG from the Hagerstown metro both get a 0.1 in the DC book. Since it's the lowest possible share would those diary market stations 1) be subscribing to the DC metro and 2) be encoding for PPM? It hardly seems worth it for a 0.1 showing in the monthlies in some books.
