Monday night at approximately 5:20 PM I logged "Radio Torrente de Vida" on 1690 KHz. Hadn't heard this one before. This station apparently operates from a church in Lynn, Massachusetts. It is fairly representative of one of the multitude of ethnic pirates that operate in the Boston area. I caught it from about 2.5 miles away from their claimed location, using my car radio while waiting in the parking lot of a train station. The station was playing Spanish language pop music with occasional identifications. Decent signal, but I suspect that this station probably does not run a lot of power and is probably only audible in a very local area.
The station currently has a web site here (in Spanish):
