Sure there are...depending on what you consider vacant. The first-adjacent frequencies are mostly vacant, except for the ones that have been appropriated by the various pirate stations, or the few first-adjacent stations in the market that have been grandfathered in, like WBLI or WPRB.
Some other frequencies are practically vacant as well. 91.9 is pretty much clear throughout the city and is a second-adjacent that I always thought should have a mid-power allocation. Instead, by day the frequency is used by a Hasidic pirate station and by night, by another pirate that plays different kinds of music, depending on what day it is....everything from dance to country!...and going by the name of WHUT. The latter station, especially, has an absolutely amazing signal when it's on, covering the entire city with a clear, sharp signal and relatively good sound quality.
