static problems

I have been using digital scanners since they came out and even know how to program them. I am working on a 396xt digital and a 996xt. I am getting static before officers talk and dispatch. It also gets hung up and stays staticy. My question is why. I am listening to OPP.

I am wondering about the p25 settings. Hold times and anything else that can help before I smash the Crap out of them.

I am listening to the primrose tower and Edgar tower.

Please help is it something in the programming I am missing.
