This depends on which model of scanner you have.I have the BC396T,BC996Tand BC780XLT all capable of following LTR trunked radio systems.What model scanner are you using to listen with?
LCN#-Frequency order-(for unidens)
03-460.0375
07- 460.1625
11-460.2375
15-460.3125
19-460.4375
Hope this helps,Tony.
