They had a solid 1.5, 1.6 in 2009 or so. The airstaff made it tolerable, Sherman & Tingle in particular. Calling Metallica "Alternative" just didn't sit well. People used to joke at how much Metallica and Red Hot Chili Peppers they would play.
87.7 averaged 2s. The first year or so when they shifted that format to 101.1 they were up in the mid 3s
FM News debuted July 2011.
I agree that Q101 at some point prior to that should've changed its positioning statement. Chicago's ROCK alternative would've been much more suitable than "Chicago's Alternative."
Underground Q at 87.7 MHz was a GREAT station.
