I have held off on asked about this on my 996 when I scan the Occone county SC Sheriff I can hear them but at random times I get nothing but data noise and it can last several minutes! I find myself looking through channel out a lot after paying for the DMR upgrade it's kinda of a loss! Now if I scan the same channels with a 436 I never hear this! I posted a video of it so you can hear it! Is there something wrong with the scanner? Am I missing a setting? Or is it encryption? I don't think I can upload video so here's a YouTube link. There's a New 536 under it but I didn't unlock the DMR yet.
