The new P25 simulcast system is causing all kinds of frustration for us. NO scanner or antenna will fully solve the problem. I have a BCD396T, HomePatrol-1, and BCD536HP. All are programmed the same--Sedgwick County, Kansas State, and some Local Conventional. The new 536 (just set up this AM) works the best. It sits on my home desk with a Radio Shack magnetic mount car scanner antenna on the window sill a few feet away. The 336 and HP-1 are hardly receiving--very hit and miss. There are soooooo many factors when dealing with this new system--scanner, antenna, location, weather, buildings, terrain, fridge temp, tire pressure, shoe size--hope you get the point that it could be anything. So, for me, the solution was a $614 new scanner.
