A pirate in Boston with the fictitious call letters WPOT (gee, wonder what the owner's smoking) broadcasting on 87.7 FM claims to broadcast in HD. I really would not be surprised if I personally hear IBUZ on 87.5 and 87.9 next time I go to Boston. Ironically, that pirate station moved to 87.7 from 97.5 because of...you guessed it...IBUZ interference from WKAF 97.7!
