Mike, KT2E asked: How accurate have you found the internal power meter/wattmeter to be on the K2??? Reply: - Mine is well within the 1/2 watt at 5 watts as stated in the specifications. Measuring RF power at QRP levels is really not difficult. A low forward-voltage drop

Mike, The K2 internal RF metering is quite accurate - BUT it depend on having a precise 50 ohm non-reactive load. The wattmeters built into the KAT2, KPA100 and KAT100 remove the dependency on a 50 ohm resistive load, but need to be properly calibrated first. Many (IMHO most) external

Hi Fellow Elecrafters, How accurate have you found the internal power meter/wattmeter to be on the K2??? I ask this because there is a large difference between what I set the power for, on the K2, and what it displays as compared to the external meter (contained in a Ten Tec tuner, scale 0
