Since I don't wear a watch nor care much about clocks neither have I but I use the signals regularly to verify receiver / SA operation and check freq stability of some of my test equipment. I have a cheap but seemingly stable GPS disciplined 10mhz osc that I guess will be my go to freq standard now. I guess that I had better get it out again and verify that it is as stable as I think it is before they hit the plate off on the big transmitters.
Was there any time frame to turn them off?
