Today at lunch I was in close call mode and picked up some comms on a different frequency out of the normal range of the common ones. Was listening to 418.6250 P25, coming in somewhat strong but the P25 was distorted now and then but heard about 95% of it. Sounded like they were following someone. Thoughts of what I was picking up? DEA perhaps? From what some of the street names I heard, sounded like in the Boston area.
