[. . . ] · Signal reception is affected by weather, atmospheric conditions, and seasonal changes. · The time calibration signal is bounced off the ionosphere. Because of this, such factors as changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to higher altitudes due to seasonal atmospheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible. · Reception is best when the back of the clock is facing toward Mainflingen.
