Current Band Plans and Frequency Assignments for WD2XSH Stations
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:
- 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.
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.
Three Canadian amateurs will be operating in the 472 - 429 kHz band.
Time: 2130Z - 0130Z Friday evening Oct 31-Nov1 TX Frequency: 477.7 kHz RX (QSX) Frequency: 3562 / 7062 kHz
Time: 0200Z - 0600Z Friday evening Nov 1(Z) TX Frequency: 473.0 kHz RX (QSX) Frequency: 3566 / 7066 kHz
Time: 0200Z - 1000Z Friday evening Nov 1(Z) TX Frequency: 474.0 kHz RX (QSX) Frequency: 3536 kHz
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!
