630-METER SPECIAL EVENT
November 12, 2016
On November 3, 1906, the Berlin treaty made 500 kHz the International Distress Frequency. 630-meter operators will commemorate the Berlin Treaty with a special event on Saturday night, November 12.
Three different groups will participate:
U.S. Part-5 Experimental Operators including WD2XSH stations and others will operate in the 472 - 479 kHz band. They will use CW transmissions for QSOs and beacons with special messages. There may also be some operation on 500 kHz itself.
Canadian Amateurs will also engage in CQ QSOs in the 472 - 479 kHz band. They will also participate in cross-band QSOs with amateurs operating on 80 and 40 meters.
The Maritime Radio Historical Society will activate its KSM/KPH transmitter at Bolinas, CA for a mini "Night of Nights" with special messages and bulletins.
Detailed information will be posted on a number of sites as the event approaches, including:

AMATEURS WIN 600 METER BAND WORLDWIDE!
Amateur Radio Obtains a Secondary Medium Frequency Allocation at WRC-12
02/14/2012 It’s official -- delegates attending the 2012 World Radiocommunication Conference (WRC-12) have approved a new 7-kilohertz-wide secondary allocation between 472-479 kHz for the Amateur Radio Service. Agenda Item 1.23 had both its first and second readings in Plenary Session on Tuesday, February 14; to become part of the ITU Radio Regulations, each Agenda Item must be read twice in Plenary Session. While the Final Acts will be signed on Friday, February 17 at the close of the Conference, the new allocation will not take effect until it is entered into the Radio Regulations. No date has been set for this, but it is unlikely to be earlier than January 1, 2013. In any case, no amateur can use the band until his or her national regulations are revised to implement the allocation.

You do not have to be a member of this group to send us a reception report.
Reception reports are welcome for ANY 600-meter station - not just WD2XSH stations. Multiple reports on the same station on different dates and times are encouraged as they allow us to see that communication is repeatable
The entire Amateur Radio community stands to benefit from your assistance!
