So after some google searches I was able to get onto the local Emergency P25 Phase 1 systems pretty easily by going into source adding multiple frequencies then putting the control and aux control frequencies in then setting the Decoder for P25 Phase 1 Simulcast (LSM).

So next I wanted to try getting the power company frequency their information is here:

I've added the frequencies in just as I did for the P25 system. Now I'm trying to figure out what decoder to use. I see it says System: Motorola Type II, but I'm not sure what decoder is good for that system.

Anyone know what I should do next?

For monitoring Smartzone you'll need either TrunkRecorder or OP25 on Linux. If you are running Windows I think Unitrunker is the one to use.
