Is it a good idea to use AM broadcast transmitters as a frequency
standard when the regulatory tolerance (ITU and many countries) for such
transmitters is +/- 10 Hz? Is that good enough for the purpose?

When I was working in BC, and later when looking at stations with an HP
precision frequency measuring instrument, I regularly saw errors less
than one Hz on the MF broadcast band with major US stations.
