I believe this is the database entry for your area:

At first glance, it looks like *most* of the services in your immediate area are using analog conventional (FM) or analog trunking which your Uniden BCT15X can already receive. I see a NXDN and a DMR system used for businesses and utilities. Depending on what you want to listen to, I am not sure there is much digital in your area to monitor.
There are also some Public Safety agencies in Nevada that are using a P25 Phase 1 trunking system (Southern Nevada Area Communications Council - SNACC). If you wanted to (or could) listen to these, you would need at least a P25 Phase 1 digital scanner.
What types of services are you interested in?
Are you considering a handheld or a desktop model (similar to your )?
What is your budget?
