Meinberg LANTIME M200 - Configure DCF77 distance
The speed of light (radio waves) in a vacuum is 299792458 meters per second. So in 1 millisecond a radiowave travels 299792,458 meters, or just short of 300km. In order to correct for this delay, you have to configure your distance to the DCF77 transmitter. My receiver is 385km away from the transmitter site. And the delay is: 385 / 299,792 = 1,284 millisecond. I don't know if Meinberg corrects for the difference between air and the perfect vacuum
