I'm surprised no one has mentioned this here yet. Q100 was flagged for possibly attempting to contact meter holders in the April Nielsen book. Apparently they ran a contest on the Bert Show and attempted to find out which listeners were carrying a meter. That's a big Nielsen no-no. They should know better than that!
