![]() If you have one of the devices which doesn't have either option you may be out of luck, but it is worth looking for the instructions just in case. The time is still accurate as the time still gets corrected, the clock just nows to add an hour to the resulting time when displaying it. With this option you can set the displayed time to offset by a specific number of hours (one in the case of Spain). If you don't have a selector switch to tell it to use the German signal, another option some clocks have is a time offset. Unfortunately I haven't found a way to set my UK model to use the frequency from Germany (I even took it apart to see if there was a way of doing this from inside the device). ![]() I have a few of these clocks, one has the UK/EU switch I mentioned and the other one does not (bought in the UK). Low-cost receiver components A receiver consists of a tuned ferrite core antenna (e.g., from HKW, 60 kHz version sold by Maplin order no MK72P, 77. Doing this should tell the clock to try to get the signal from Germany. Robust receivers can be constructed very easily for as little as 2030 USD/EUR and are found today in many radio clocks. Look for something like a UK/EU slider position and set it to the EU if available. ![]() The time code signal can be received upto 1500km from Frankfurt. P5 (Power-Down / Fast-Start) Receiver powered down if P50v (although on-board shunt regulator still active). What is the coverage of the DCF time signal The DCF radio time code signal is broadcast from Frankfurt, Germany, the coverage of the DCF signal is the whole of the Germany. P4 (+supply) e.g +5v ±½volt (note different voltage ranges possible). Some devices have a switch which you can use to tell the device where to pull the signal from. STANDARD FREQUENCY & TIME SIGNAL BROADCASTS SF/TS, STANDARD FREQUENCY & TIME SIGNALS Class : Standard Frequency & Time Signal Broadcast (Continuous). P3 (Out) Open drain data output signal, pulled to 0v when no carrier, high impedance (high) when carrier present. Assuming your device is getting a signal (generally better at night) - it sounds to me that your device is locking onto the UK signal from Rugby and hence displaying GMT (UTC) time. Easily keep track of time of day in hours and minutes with any of these wall-mounted clocks. Unless this has changed, clocks that are automatically updated by a radio signal in Europe use one of two long wave radio signals, one is from Rugby, UK and the other one comes from Germany (I think Frankfurt). Controlling radio signal from NIST (National Institute of Standards and Technology) in Colorado automatically adjusts clock to reflect precise time, daylight savings, leap year, and leap seconds (earth rotation wobble corrections).
