I see this problem on certain parts of certain bands when using certain antennas. I believe it is caused by RF getting into the K2. In the first scenario, it is causing a reset of the rig, much like it just powered on. In the second scenario, it is interfering with the computer dialog between the microcontrollers between the K2 and the KAT100. Perhaps just resetting the KAT100. If I switch to other antennas / frequencies the problem will go away. It will also go away if I reduce power somewhat.
