Check out Radio Reference web site!
 

For those of you that haven't already done so, be sure to check out the
Radio Reference web site! It is a very active, and current resource for
everything having to do with our scanner radio hobby. They have a national
frequency database like no other! You have to create a user I.D., and
Password to access it, but its no trouble. They do accept donations,
(definitely worth it), but it's not required. No riff-raff either!
