sorry to be the one to tell you this, but your r10 will not scan the highway patrol. you will need a trunk tracking scanner that can follow an EDACS type of system. if you look in the wiki at the top of the page you will find a very good introduction to trunk tracking. also in the data base section you will also find all the information you need to program into the scanner (frequencies and talkgroup numbers).Henderson police, anda North Las Vegas Police also require a trunk tracking scanner to listen too. You can still listen to Metro though, and they can be very exciting. Sorry for the bad news, but, it is a great excuse to go buy some new gear!!!
