Ok I need help. I just moved into a new house and my reception is crap now. If I put my scanner outside it works fine the second I bring it in I can only pick up local departments. I live in Baltimore and the city are county are both using a P25 system.. Like I said county works fine city is another story. Its almost like this house is lead lined. My questions is I see they sell amplifires for scanners are they any good? Or am I wasting my money? How about a antenna upgrade what is good or again wasting my time? I have three scanners all radio shacks a Pro 96,2096 and a Pro 106. All worked wonderful till the new house. I am scratching my head now. Thanks in advance.
