Mark, First, set the CAL CUR in the K2 menu to 3.50 - and also make certain the power supply voltage as displayed on the K2 display is not dropping significantly during a TUNE. If it drops more than 1 volt suspect your power supply or the power cable. A low supply voltage can cause the K2

Just installed the KAT2 in a newly assembled K2. At power levels greater than 8.0 watts, the K2 was displaying the high current warning. The KAT2 power calibration was calibrated by measuring voltage with the K2's RF probe at the feed point to a dummy load. I removed the KAT2 and remeasured
