I am puzzled as to why I can capture heavy radio traffic from the Sawyer Co. Wisconsin jail for 1-5 weeks a year, then its gone for most of the rest of the year, its not digitized in some fashion, it just literally disappears???? I have absolutely no idea what the deal is, it just vanishes into thin air.... and by capture I mean its there all day long, dozens and dozens of captures each day whilst its available, easily the busiest traffic I catch on a Uniden 536HP, more so than the Sawyer Co Sheriffs office as it patrols county roads.
