I just got a BCD396XT. When I connect it to my PC via the supplied cable (or with another cable I had for my "T") I get some strange audio. Loud pops at the beginning and end of transmissions, and sometimes severly distorted audio. I want to use the new scanner for my live feed, but it sounds terrible when it's connected to the PC. Anyone have any idea how to fix this? I've tried changing every setting that I can think of. (AGC analog & Dig, Referance gain's, P25 wait times, End code, Status bit, Tone search, Closecall settings, Vol. Offset). Even witht he audio cable disconnected the popping sound is present when the data cable is connected. HELP!
