I finally seem to have a working TTD setup. Issue is that if TTD is left running all day the audio level creeps up for some reason. The scanner is not being touched and I am using one of the cheap USB sound cards input into the microphone port. I adjust the squelch level in TTD but it creeps up more. Once I restart TTD it resets and is good again. Should I be restarting TTD every few hours or did I miss something in the setup?
