Detail of Frequency Band

Band reserved for non-civil utilisation. If civil utilisation is also stated with priority, the band is being used equally with civil utilisation on the basis of coordination.

Non-civil stations can use the band with subsidiarity to civil ones (which use the band with priority), but must not interfere and do not have rihgt to protection against interference by civil utilisation.

Non-civil stations cannot use the band.

On the frequencies of fixed and land mobile services notified with Radiocommunication Bureau of ITU, the primary user is that one for which frequencies have been recorded at Radiocommunication Bureau of ITU and are noted at the Czech Telecommunication Office.

The use of the bands 14 – 19.95 kHz, 20.05 – 70 kHz and 70 – 90 kHz (72 – 84 kHz and 86 – 90 kHz in Region 1) by the maritime mobile service is limited to coast radiotelegraph stations (A1A and F1B only). Exceptionally, the use of class J2B or J7B emissions is authorized subject to the necessary bandwidth not exceeding that normally used for class A1A or F1B emissions in the band concerned.

In the bands 70 – 90 kHz (70 – 86 kHz in Region 1) and 110 – 130 kHz (112 – 130 kHz in Region 1), pulsed radionavigation systems may be used on condition that they do not cause harmful interference to other services to which these bands are allocated.
