There is an anomaly when using the weather alert on the KG-935G and the KG-XS20G. When selected 'On' and scanning in area A, the scan will be continuously interrupted while it interrogates the NOAA weather channels for an alert tone. This is very distracting and inefficient. There are two ways to work around this "feature"; (1) Turn off weather alert or (2) Set your scan in area B where it will not be interrupted. The weather scan only occurs in area A.
If you find your scan still being interrupted by the weather frequencies, no matter what you do, then set Scan Mode to 'CO'
