I don't think you can conclude anything by monitoring the transmitter with a separate nearby receiver. Have you tried measuring the power output with a power meter or even an SWR meter? Your current readings look just like what would be expected, and I suspect there is nothing whatsoever wrong with your K2. Put a power meter or swr meter in series with the dummy load and tell us what that says.
