Berlin Treaty Special Event – Saturday night, November 12, 2016

– Posted in: Uncategorized

UPDATE: November 6, 2016:

Steve, VE7SL, just posted the following announcement to a number of email reflectors  with additional information and intent for the event:

“I know there are several folks on this list in NA that are interested in 630m band actvities. Some of you may even be planning to get on 630 when it becomes a ham band in the U.S. Here in Canada, we’ve had the band for a couple of years now and regular ‘crossband’ QSO events have allowed interested amateurs in North America to explore the band’s potential by working the 630m Canadians.

The next ‘crossband evening’ will be one week from tonight, on Saturday, November 12th.

As in previous events, the participating Canadian CW stations will be calling CQ on specific allocated frequencies and will be listening on their announced HF (QSX) frequencies, within the 160, 80 and 40m bands. In past crossband nights, transcontinental CW QSO’s have been completed as have contacts between the west coast and Hawaii.

The popularity of this event has continued to increase each year as more and more amateurs become interested in this part of the spectrum (472 – 479 kHz). Hopefully this trend will continue next weekend and that you will consider taking part in the one night event.

As in the past, numerous U.S. ‘experimental’ stations will be active on the band, either running CW beacons or seeking two-way QSO’s with other stations in the experimental service. As well, some may be operating WSPR or JT9 modes. All are interested in your reception reports and most of the experimental callsigns can be found via a QRZ.com lookup.

The Maritime Radio Historical Society are also promising activity, as KSM / KPH in Bolinas, California will be activated for the night, sending weather notices, press bulletins and possibly engaging in two-way work with historical naval ships involved with the MHRS.

All told, there will be six different participating Canadian stations that will cover most regions of the continent, should propagation co-operate!

More information as well as a detailed schedule of times and frequencies may be found here:


As well, if you have not participated previously, you will find some useful hints to help you out.

Details were previously released on both the ARRL and RAC ‘news’ pages, here:


and here:


I will also post a reminder next Friday, one day before the event. I would also ask and encourage you to pass this information forward within your blogs / Facebook / Twitter pages as well so that as many amateurs as possible are aware of the activity. Please e-mail me if you have any questions and we all hope to see as many participants as possible next Saturday night!

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. Experimental Operators,
  • Canadian Amateurs, and
  • Maritime Radio Historical Society.

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.
