I traded messages with the guys at
BuyTwoWayRadios.com about the software problem with the
KG-UV8D.
They've seen a problem where the radio shuts down when transmitting. They aren't 100% sure, but the common factor seems to be that the customers had used the frequency adjusting software. They are working with Wouxun to find out more, but that will take some time.
It sounds like they are working hard to keep their customers happy, but I would recommend avoiding the frequency expanding software just in case.
