    Good day. I have recently been using radio-controlled clocks in various rooms. In my experience, there is probably no signal in some locations and the clocks do not set. It is obvious. The solution is simple; either you have to change the clock position or just give it up. However, in the present case, in a room where I decided to mount two of such clocks, I encounter at least their bizarre behavior. I will explain that one clock is a dial for reading the time of the day, the other has a digital display for reading the time of the night. In this room, although it is also strange, because it is located on the top, eighth, floor of the building and has a window facing west, and from there (from Germany), if I'm not mistaken, a signal comes, I found only one place, on the wall, just opposite this window facing west, where the clocks react and carry out the adjustment procedure. So I installed them there. But here, an abnormal thing is happening. Here the clocks set around 01:00 at night so that the hands on the digital clock first run for twelve hours, and then set the right time, except that it is the time ... ALWAYS one forward. So if we have, for example, 13:20, as it is at the moment, this clock indicates 14:20 ... With the digital clock it is similar, it also sets, but apart from the fact that it also indicates exactly one hour ahead, additionally at 14:20 it indicates 02:20, and at night, at 02:20 it indicates 14:20, which means it has a 12-hour shift ... Both of them set themselves every day for a long time always with the same result. What is this about Why is this happening? I checked to make sure that sometimes in Germany they did not stop switching from summer to winter time, which could explain this anomaly to some extent, but in Germany the time is consistent with ours, i.e. one hour earlier than the one shown by both my digitally controlled clocks . What else stupidity trying to explain this phenomenon comes to my mind is that maybe somewhere is broadcasting some other signal, which my clocks catch in return the right one from Germany ... Did anyone have a similar problem and have any suggestion what is here going on? Greetings to all.

    He did not wonder Colleague if it is not the case that the hour hand is not in its factory place? Or maybe someone didn't mechanically adjust it to show such interesting indications?

    I have the Twins clock from Biedronka and I have observed its deviations in showing time and date several times. I think that the occurrence of these distortions is caused by some interference from the DCF time transmitter signal, hence our clocks present themselves to a different time transmitter and show a different time than they should.

    Probably no German time signal is broadcast, only UTC time, i.e. +1 for Poland, which would be correct. There should be a possibility of correction in the clock settings.

    During automatic adjustment, the minute hand first rotates around the dial until the hour hand makes the entire turn around the dial and all three hands stop at 12:00. Then they switch to the current time. In this situation, it does not seem logical to me to look for the reason in the original position of the clues.

    It seems strange to me because, first of all, I have never heard of the existence of another signal for setting the radio clocks, and secondly, logically speaking, it is difficult to imagine a more suitable place to correctly receive the right signal from Germany, since, as already I mentioned earlier, the room window is facing west and is located relatively high, eighth floor, so it is difficult to explain signal reception problems with some terrain obstacles.

    I think I know the instructions for both clocks by heart; I don't remember any hints regarding the possibility of time correction. And besides, if the German time signal is not transmitted, as you suggest, then it really must be some other transmitter, because the one from Germany gives the correct time, because two floors below, in another room with a window, ironically facing east, another clock is being set correctly ...: - /

    So how do clocks know where they are? I have had one from Lidl for several years and in fact, now I thought that I do not set anything after replacing the battery and it sets itself correctly for Polish time. I just have to put it out the window. Maybe clocks are made for a specific location? What is the origin of yours?

    One bought on "Allegro", while the other ... on "Allegro" ... ;-) If I find auctions, I will put links. If it matters, they were not expensive equipment, but when buying I did not think that it could affect their operation. As a side note, I bought these clocks, two pieces each, and the digital ones I already advertised because the manual time setting function did not work.

    Clocks may have an MCF-60 receiver instead of DCF-77, hence the difference of indication in relation to our time may result, in the offer of a certain company there are clocks that have two receivers. Possible sources of interference - household appliances without radio interference suppressors / TV receivers closer than 2m / devices emitting high frequencies (e.g. PC) / being out of range of the transmitter (1500 km); Topographic and meteorological conditions may also affect the reception of the signal.

    After a few months of not staying in a room with a clock, I discovered that it was suddenly set correctly. I rarely stay in this room, but I will keep watching him. In the near future I plan to install a permanent power supply system for this clock from the power supply and an adapter. Under these circumstances, of course, I will have to disconnect the clock from the power supply, so it will "detun" again, and then I will see if it will "recover" again ... ;-)

Topic summary

The discussion revolves around issues with radio-controlled clocks, particularly regarding signal reception and time adjustment. The user reports strange behavior when using two clocks in a room on the eighth floor, where one clock displays the time of day and the other the time of night. Despite being positioned to receive a signal from Germany, the clocks exhibit abnormal time settings. Responses suggest potential causes for the discrepancies, including interference from household appliances, the possibility of different signal receivers (MCF-60 vs. DCF-77), and the need for proper positioning to receive the correct time signal. Some users share experiences with similar clocks, noting that certain models may not automatically adjust based on location. The conversation highlights the importance of understanding the signal sources and the potential for environmental factors to affect clock performance.
