Upcoming 630-meter special event – November 13/14, 2015

– Posted in: 630 Meter General Topics, 630 Meters

The following  information was posted on the 600mrg reflector today.  Last year was actually quite a bit of fun for those of us that generated both NTS and commercial message traffic and forwarded or relayed it to one another in addition to the crossband activity conducted by the VE’s.  I suspect this year will be much of the same, even if we really don’t know the whole story behind the Berlin Treaty…


Updated 10/26/15

The 630/600-meter operators will be conducting
a special event during the weekend of November 13 – 14.
This event marks the 107th anniversary of the
Berlin Treaty that created the international distress
frequency at 500 kHz.  This event includes US experimental
stations, Canadian amateur stations, and (we hope) US heritage
maritime stations.


For US experimental ops, this will be a CW event and
the main activities will be:

–  Some stations will run beacons with special messages,
and some will offer special QSLs.

–  Other stations will simulation maritime communication.
They will call CQ on a designated calling frequency and
then QSY to complete the QSO.  Silent periods will
be observed.

–  Some stations will pass message traffic.

–  The frequency bands are
465 to 480 kHz and
495 to 510 kHz.
Different licensees have different frequency authorizations.

–  The designated calling frequencies are
475 kHz for the lower band
500 kHz for the upper band.


The Maritime Radio Historical Society (MRHS) will
conduct a mini “Night of Nights” on Saturday night,
with special attention to MF operations.  This will
give listeners the best chance of copying their MF
signals by operating during the winter and extending our
operating hours well into the evening hours Pacific time.
KPH will keep 500 kc and 426 kc (and HF) active with
special messages, press and weather.  And they will
send a verification to any listeners who mail in a
reception report.


Five Canadian amateurs will be operating in the
472 – 429 kHz band.

In addition to activities similar to those of the US
experimental stations, the Canadian amateurs will
conduct cross-band communication tests with amateurs
operating on 80 and 40 meters.  The plans include:

Station: VO1NA (Joe) GN37 Torbay, Newfoundland
Time: 2130Z – 0130Z both Friday night (Nov 13-14Z) / Saturday night (Nov

Station: VA7MM (Mark) CN89 Coquitlam, B.C.
Time: 0500Z – 0700Z Friday (Nov 14Z)
0400Z – 0800Z Saturday (Nov 15Z)

TX Frequency: 476.0 kHz
RX (QSX) Frequency: 3558 kHz / 7062 kHz

All stations will either call CQ or run “VVV”
marker beacons while listening on their respective
QSX frequencies.  QSX frequencies will be included
in the CQ or marker beacon.


The official time period is

00:00 Z on Nov. 14


23:59 Z on Nov. 15.

These include Friday and Saturday evenings in North
America.  Stations on the east coast may start a
little earlier if they like.
