SPECIAL EVENT - 630/600 METERS

 The 630/600-meter operators will be conducting a special event during the weekend of Oct 31 - Nov 1 - Nov. 2.

This event marks the 106th anniversary of the Berlin Treaty that created the international distress frequency at 500 kHz.  This event includes US experimental stations, Canadian amateur stations, and US heritage maritime stations.

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

 -  Some stations will run beacons with special anniversary messages, perhaps followed by 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.

-  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.

 
-  This may be the last such event with operations on 500 kHz itself.  This band is not being included in new experimental licenses as it is supposedly reserved for a new maritime-data service.

Plus,

     The Maritime Radio Historical Society (MRHS) will conduct a mini "Night of Nights" 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. They will send a verification to any listeners who mail in a reception report.

Also,

     Three 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 Friday evening Oct 31-Nov1 TX Frequency: 477.7 kHz RX (QSX) Frequency: 3562 / 7062 kHz

 
Station: VE7SL (Steve) CN88 Mayne Island, B.C.

Time: 0200Z - 0600Z Friday evening Nov 1(Z) TX Frequency: 473.0 kHz RX (QSX) Frequency: 3566 / 7066 kHz

 
Station: VE7BDQ (John) CN87 Delta, B.C.

Time: 0200Z - 1000Z Friday evening Nov 1(Z) TX Frequency: 474.0 kHz RX (QSX) Frequency: 3536 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 on Nov. 1 through 23:59 on Nov. 2.

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




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.

RECEPTION REPORTS

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!
