I use Monroe East since I am in Brighton. If you are on the Westside, Monroe West is probaly best. Monroe East tends to have most TGs other than some FD local TGs in the far west. Monroe East usually has Ontario Law and Fire Dispatch TGs active. Monroe South may have some additional Ontario actvity but miss some low activity Monroe TGs. RPD should be good on both East and West at all times.Which system do you have it set on?
