I'm locked on a P25 Simulcast system and have both a Pro-197 and Pro-106 and both have days where the P25 Armor system is so gargled that I can't make out what is being said. Signal strength is full, software is updated to Ver. 2.0 and I've tried Global Att on or off and it seems to be a weather issue. Somedays are fine with clear sound and others are very very bad. Anyone have any ideas how to correct the problem? I have a outdoor antenna installed. No gargle on WX channels or Conv. channels ever, just digital P25.
