Dynon Heading Calibration

[Steve Y]

My Dynon in the CC is about 15-20 degrees off on the magnetic
heading. Following the Magnetic Compass Calibration instructions in the Installation
Manual, I find I must first get the "Magnetic Inclination and Intensity"
of the airport that I'm at to do a calibration. Since our government is on paid vacation,
the only NOAA web site that Dynon tells you to go to is closed! I have used the
manual adjust to get the heading closer to correct, but it would be nice
to try a proper calibration. Anyone know the [INCLINATION and TOTAL FIELD]
numbers for KTRM (Thermal, CA.) ? Even the local avionics guys and Dynon customer
support don't know it!
