I think it's Lincoln County Fire Prot District in Troy, MO.
They are licensed for conventional P25 on that frequency as well as a few others.
Look at the FCC site for call sign KZR643.
I get a good signal from them here in east Chesterfield with the same NAC of 441.
I heard the same trucks talking on 151.430 NAC 444 also which is also licensed under the same callsign above.
154.145 with nac 441 is Winfield/Foley FPD in our county list it is OPS 1.
LCPFD#1 is OPS 4. old LCFPD#1 (158.805) is now fd & ems paging, LC PAGING.
FYI if we reference as dept name it tis analog, if we refence it as OPS # it is P25.
