    Amateur Radio operators will descend upon 630 meters on November 11 during a special operating event to commemorate the 1906 Berlin Treaty, which made 500 kHz the International Distress Frequency on November 3 of that year. US radio amateurs recently gained access to 630 meters but must have notified[1] the Utilities Technology Council (UTC[2]) of their intent to operate and either received explicit approval or not heard anything for 30 days in order to participate.

    Four different groups will take part: US radio amateurs, US Part 5 Experimental operators, Canadian radio amateurs, and the Maritime Radio Historical Society (MRHS[3]). Canadian and authorized US radio amateurs will operate from 472 to 479 kHz, using CW.

    Some stations are expected to offer cross-band contacts, transmitting on 630 meters and listening on 160, 80, and 40 meters. Part 5 Experimental operators, including WD2XSH stations and others who don't yet have UTC approval, will operate in the 472-479 kHz band or just outside of it, and there may be some operation on 500 kHz proper.

    The Maritime Radio Historical Society will activate its KSM/KPH transmitter at Bolinas, California, for a mini "Night of Nights" with special messages and bulletins.
