Standard frequency and time signal radio station DCF77
Transmission of the time signal transmitter YVTO

The standard frequency and time signal radio service ( English standard frequency and time signal service ) is as defined by the International Telecommunication Union (ITU) in the Radio Regulations , a radio service , to scientific in which technical and other purposes normal frequencies , time signals simultaneously emitted or both with a fixed high accuracy and in which the broadcasts are intended for general reception.

    1. ↑ VO Funk, Article 1.53, 2012 edition
    2. ↑ Uppercase : primary assignment
    3. ↑ 2: Frequencies up to 30,000 kHz can be used for induction radio systems. The limit values ​​of the interference-relevant parameters of induction radio systems are specified in the frequency plan or the required frequency allocation. Induction radio systems must not cause any interference with other radio systems and radio services currently and in the future to which the corresponding frequency ranges are assigned on a primary or secondary basis. Interference from these other radio systems and radio services must be accepted by induction radio systems.
    4. ↑ 3: In the frequency ranges 9 - 14 kHz, 72 - 112 kHz, 115 - 126 kHz, 3 500 - 3 800 kHz, 4 063 - 4 438 kHz, 5 900 - 6 525 kHz, 7 300 - 7 350 kHz, 8 195 - 8 815 kHz, 9 400 - 9 900 kHz, 11 600 - 11 650 kHz, 12 050 - 12 100 kHz, 12 330 - 13 200 kHz, 13 570 - 13 600 kHz, 13 800 - 13 870 kHz, 15 600 - 15 800 kHz, 16 460 - 17 360 kHz, 17 480 - 17 550 kHz, 18 900 - 19 020 kHz, 22 000 - 22 720 kHz, 25 070 - 25 110 kHz, 26 100– 26 175 kHz, 28 000 - 29 700 kHz, 34.35 - 36.55 MHz, 38.45 - 39 MHz, 137 - 138 MHz, 144 - 223 MHz, 410 - 862 MHz, 1 525 - 1 535 MHz, 1 660.5 - 1 700 MHz , 2 290 - 2 300 MHz, 3 400 - 3 600 MHz, 5 150 - 5 255 MHz, 5 850 - 6 525 MHz, 14 - 14.62 GHz, 15.23 - 15.35 GHz, 17.3 - 17 , 7 GHz, 23 - 23.6 GHz, 31 - 31.3 GHz and 66 - 71 GHz, individual frequencies are used for military purposes.
    5. ↑ 5: ISM applications can also use frequency ranges that are assigned to radio services in the frequency range 9 kHz - 300 GHz if the frequencies required for this use are specified due to the desired physical effect and cannot be freely selected. The limit values ​​of the permissible radiation and other parameters relevant to interference for these ISM applications are specified in the required frequency allocation from the point of view of radio compatibility. The ISM usage according to this usage provision must not cause any interference with other radio systems and radio services currently and in the future. The shared use of frequencies by ISM applications in frequency ranges that are dedicated to safety-relevant radio applications is excluded.
    6. ↑ D111 : The carrier frequencies 2 182 kHz, 3 023 kHz, 5 680 kHz and 8 364 kHz as well as the frequencies 121.5 MHz, 156.525 MHz, 156.8 MHz and 243 MHz may be used in accordance with the procedures applicable to terrestrial radio services are also used for search and rescue work if this concerns manned spacecraft. This also applies to the frequencies 10 003 kHz, 14 993 kHz and 19 993 kHz, but the emissions on each of these frequencies must be kept within the limits of ± 3 kHz of the relevant frequency.
