How stable are they? Could they provide a good regional reference if somebody with a good setup would measure several stations and publish the results? How often would you have to measure? How do you measure the frequency of an AM or FM station? Wait for silence and process it like CW? Any suggestions for a receiver (or whatever) that would be appropriate for that sort of project? I assume the main requirements are an external freq in and a serial/USB port to adjust the knobs. ---------- Ages ago, I remember seeing a small booklet (20 pages?) from NBS describing their setup with HP that was using NBC's atomic clock for time distribution. HP's part was to run the west coast calibration to get the delay over phone lines from the east coast to the west coast. Has anybody seen a copy of that booklet online? -- These are my opinions.
