If theres any doubt about who you hear-do what I do. It may take time, but if you really want to know who it is, just devote 1 scanner to whom you are tuned in on. You have to listen closely. Sooner or later they will say something about a delivery in your area. When they say they are coming, dont rush, trucks go slow.If it is an address you know-ask the occupant. I recently tried getting an entity that is ltr. Boy, the fun I had sepparating them. Well, this 1 entity said they were all done at a certain pizza joint. I called that place asking who it was that I saw -and how good are they? Well, after a little white lie-I got the guy to tell me who was there. Remember-if you turn your back-they will chat. It all comes down to how badly do you want to know who it is. Course-down here in York County, I got Strafford County-Rockingham and York all getting my attention. When it comes to public safety-in N.H they call 10-4 10-5 in N.H terms. Thats a good clue for me-but you got 10-4 all day long.. Well, best of luck. Listen-and you will hear. May take some time,but how bad do you want to know whats what.
