I just picked up a BCD396T. I used Freescan and imported Madison County to the scanner via my RR account. It is currently scanning and I am getting hardly anything. I see the signal strength moving between 1 and 3. Do I need a better antenna? It seems to sit on 460.4500 and DAT keeps coming up next to it. GRP 1,2,3 are on so I know it is scanning. Any ideas!
