Bad compass issues

I just bought a Pixhawk kit from mRobotics, my 2nd one from them. It comes with their Ublox GPS/compass unit as well. I have the Pixhawk and GPS/compass unit taped to a piece of cardboard to maintain their orientations for bench testing.

The compass calibration seems to go okay, although the numbers seem high. I tried both the onboard and live calibrations with similar results.

After the calibration, I'm still getting a lot of "Inconsistent Compasses" and "Compass Variance" errors.

I can load the EKF status window and slowly yaw the system and watch the compass EKF go off the chart relatively quickly.

Any suggestions?
