I have a list of frequencies that I've heard activity on but can't identify. Below is a list of some of those frequencies. I'm hoping to find the identity of these frequencies so that I can decide whether their of any interest to me or not. Keep in mind while reading these that I'm rather new to scanning, so I don't know all the frequencies very well just yet. I have checked the database, as well as Radioshack's Police Call book, but still could not identify these frequencies. Also, I'm in Baltimore Co. using a Pro-94 from Radioshack, if that might give you a better idea of what I could possibly be hearing. Here they are:
143.985 451.300 856.387
143.990 464.000 856.637
147.135 463.175 816.000
147.525 460.387 855.537
