In early January 2013, an update to the Wouxun programmer(s) affected the "Scan Add" function. This update broke the files previously had "Scan Add" turned on, it shut the feature off. Affected programmers include:
KG-UV123 / KG-UV3X / KG-UV6D/X / KG-UVA1
What you'll need to do is just turn the scan function back on by checking the box for "Scan Add". That will enable scanning for the channel again. We had to push this update so that copy and paste would read in frequencies with scan turned on. Also, for future frequencies added in, it will automatically turn "Scan Add" on, so you won't have to check the box. To remove the frequency from scanning, all you'll need to do is uncheck the box for "Scan Add".
We apologize for the inconvenience. Everything is running properly now. Should you have any trouble, feel free to contact us via email (firstname.lastname@example.org) or over the phone (303-586-6510 M-F 8-5 Mountain Time).
