The following proposal was passed unanimously by the members attending the Annual Meeting of the Radio Officers Association held at Poole, Dorset, England on 13th May 2006.
Radiotelegraphy Heritage Frequency (RHF)
That the frequency of 500 kHz be designated as the Radiotelegraphy Heritage Frequency.
Recognising that the two NAVTEX frequencies of 490 kHz and 518 kHz are vital components of GMDSS for the dissemination of Maritime Safety Information and are likely to remain so in the future. Therefore the proposed heritage frequency band is suggested to ensure that there will be no interference with this service. It is proposed that either:-
495 kHz to 505 kHz
495 kHz to 513 kHz
be designated as the radiotelegraphy heritage band.
