I have DX4WIN v7.04.04 and using it with the K3. I am having the following problems when I double click a spot. When I double click a spot with a split, a) the VFO B mode doesn't change and b) split does not stay on. I can see the split indicator go on but then it goes out. Is there a newer version of the K3 radio file? Any ideas? Bob Serwy - N9RS
