I live in Warren County and i just recently got a scanner. I know A while back I had a hand help scanner and I could pick up the volunteer fire dept and the sheriffs department. I currently have a 800mhz uniden scanner and i cannot pick up anything. I have heard that the sheriffs dept switched to a new system similar to the Vicksburg PD and you could not listen to them on the scanner. Does anyone know if this is true? IF not any idea what i might be doing wrong? I have searched for the correct freq. and programmed them in and also manually went through all bands and have not been able to find but one channel with someone talking about coordinates and the Weather channel. Any tips?
