I scan pretty much every band that scanners can get. While scanning the MURS frequencies im getting what sounds like correction dept comms on 151.820. I get them full scale. I think I am getting the Ash St. Regional lock-up facility. I know the Bristol county HOC operates on 856.3875. I thought Ash st. would also be on the 800 frequency to. I've been listening for the past couple of days trying to confirm who is using it. When they're calling each other they say Officer so and so calling another officer. Then give locations within building which also sound like corrections like rotunda and mess hall.
