We have done it! 🥳 Polskie Radio S. A., together with the Central Office for Measures in Warsaw, has successfully started broadcasting the official time signal DIGITAL in Poland on long wave at 225 kHz from RCN Solec Kujawski 😎 This is another technical signal (after control signals for energy systems and industrial automation for various receivers) broadcast on this frequency.
The time signal (e-CzasPL Radio project), which is generated according to an atomic standard, has a similar frame structure to DCF77, but surpasses DCF in terms of signal strength, range, coding (phase modulation) and a much higher frequency of transmission of successive signal frames (and thus a much higher overall immunity to interference). In the first quarter of next year, the accuracy of the signal on the ground wave should reach the order of microseconds (as a reminder - the accuracy of the 225 kHz frequency alone is in the order of pHz/Hz) 🧐.
Such a time standard is successfully used by industrial consumers (e.g. energy consumers - tariffing), infrastructure consumers (e.g. tickets, master clocks) as well as government services and research organisations. The Weights and Measures Office also provides electronic circuit designs for self-assembly that are designed to receive the digital long-wave time signal 🤩.
