The 5000's are great radios. I use an XPR 6550 because CSU Maritime uses DMR. Vallejo PD and Solano provide for great listening when it's busy. Looks like you live near the Bay Area as well!
This is why I love the apx line on a system, it can tattle tale on a system with otar otap if the user has jerked with the radios programming, read it, altered in anyway. We fired numerous folks already over this. They are lucky they didn't face computer crime charges.
Radio ID's aren't encrypted. Same goes for the talk group number. Only the voice will be protected. Apparently there may be some security enhancements in the pipeline for P25 such as: -Encrypted Control Channel - Encrypted metadata (RID, TG)
