Noted this signal several weeks ago when I got a new car radio that tunes down to 87.5. Music only, no voice. Seems a 24 HR operation. Plays alot of 1980's obscure punk rock, rock, reggae. Weekends also plays other stuff. Best signal near Rte 38 Lowell-Tewksbury border. Signal disappears in 2 miles eat of west of that QTH. Nice mod, clear audio. Not sure if stereo or not as new radio doesn't have a stereo indicator.
