Awesome! Thanks everyone - Turning off weather alerts seems to have resolved the issue for me as well!

Turning off weather alerts fixed it for me. Thanks!

Here is a short clip of my KG935G running a scan and it never stops unless there is a legit signal. 
My scan has no weather alert or priority..  Make sure those are not enabled.

Very strange! 
You say that if you manually flip from one channel to the next there is zero trace of any silent signals but if you let the radio scan it always finds rogue signals that disappear when you stop the scan...   That is bizarre. 
I would send a video of this to two way radio or whoever you purchased it from.   
Too bad you don't have another KG935G to establish a base line.    Good Luck!

I occasionally have the scan stop on either GMRS02 or GMRS06 when I am in the car, but it is normally accompanied by digital signal audio from some close by device. Does this happen on the same channels every time or most of the time? You might check your squelch settings. If you can get to the radio while it is stopped you might try pressing the monitor button to see if you can hear anything. Are you using Priority Scan? I am sure someone who knows more than I do will have some suggestions.
