I Don’t think there is much on the FIRST Trunked system for Montgomery County since they have there own talk group. For example MCPD, MCFRS, Sheriff, Corrections etc... is all done on the Montgomery County Trunked System. The only stuff I can think of on the FIRST system would be MDOT highway stuff and possibly ICC Police stuff. But yeah most stuff inside the county is done on the Montgomery County system. Let me know if this helps and if you have any more questions
