Today I learned that VOR stations are all set to magnetic north at the time of commission, and since magnetic north moves, the VOR is not necessarily in-line with magnetic north in the present.
Where can a pilot look to read numerically what the VOR is set to as its magnetic north? I understand a sectional chart could be measured, but I want to know where I can read the setting in a manual.
For example, is it contained in chart supplements?
