Bartonville,IL PD/Fire

Hello all, recently Bartonville Police and Fire switched over to Harris P25 phase 2. I bought a Uniden BCD436 so I can monitor them and others that will soon be added in the Peoria,IL area. My problem is that I cant seem to catch every transmission and if I do its somewhat garbled even sometimes so bad it can't be understood. My signal strength is at 5 bars. Is there something I can do that will help, settings ETC.?



Thanks
