The new radios will work on SAFE-T, both the current Legacy System, and the P25 upgrade once its done. When need arises for them to use the SAFE-T they now can with no issues as compared to the past. The mobiles are still the same and County uses the same Conventional, and LTR as always until the change over to the IDPS once System 4 is built and online. The HT's are set up for SAFE-T, and will have the IDPS once that is ready. On power up, the HT's will affiliate with the nearest SAFE-T site to them. Only when PTT is pressed will you see any traffic. It is nice that they can now use the system if needed without hassles. Anderson included. I wouldn't expect a lot of traffic on SAFE-T from them unless they need mutual aid or there are issues with the LTR and Conventional systems. But it would be worth having the SWMA's, Regional MA's, and MadCo TG's in your scan pattern from now on if you haven't in the past. I would log every one of the RID's you can as those will come in handy once the new IDPS S4 P25 is up.
