Is it a good idea to use AM broadcast transmitters as a frequency
standard when the regulatory tolerance (ITU and many countries) for such

Hi Richard,
I would expect many to be at least GPS locked. Droitwich 198kHz is
rubidium atomic clock locked at less than 10e-11 Hz per day accuracy!
At least until they run out of transmitting valves.
