Is there a resource for Radio ID's?

My local system "Morris County Public Safety" has put a number of PD's on the same talk group (like 7 or 8) and I find I have to listen to a lot of other traffic just to get my local PD.



I know I can hook my scanner (536HP) to my computer and troll for Radio ID's but I'm sure I'd never get a complete list.



Is there a resource that would show all the RID's of a particular department? Specifically Mendham Twp & Mendham Borough. Same goes for the Fire/EMS.



I've heard that these RID's are assigned in ranges so I was hoping maybe just getting the different ranges would work as well.



Thanks,



Roveer
