Ok I just bought a BC246t. I used arc246 and downloads from radioreference to program it. My problem is on one county they use convential system type and on the neighboring county they use Motorola Type 2 800MHz Smartzone. All freq seemed to download and install correctly. And I can listen to the convential system fine. BUT the trunked systems all sound like a machine gun. Nothing is dicernable. Need help because I can't figure this out. The county in question is Dougherty County Georgia.
