I'm a little new to scanners so here I go. I just received my uniden bearcat 436 hp scanner. They preprogrammed for my county and I also purchased the NXDN upgrade because my city and sheriff's dispatch operate on NXDN. I don't get anything from the city of Enterprise Alabama or coffee county sheriff's. I'm several miles from both towers. Bearcat Warehouse said they've done all they could do. I believe this is a program or possibly software issue. I need help. I've had scanner for 6 days.
