USA AMATEURS GRANTED 630-METER BAND!

On 27 March 2017, as part of Report and Order FCC 17-33, the FCC adopted the final rules for the USA 630-Meter band.

Operation on the new band cannot begin immediately, because PLC coordination between Amateur stations and the Utilities Telecom Council (UTC) is required prior to the Amareur station beginning transmissions. Further details about the specifics of the coordination procedure will be released by the Wireless Telecommunications Bureau.

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.

These maps have been compiled by Ralph Wallio, W0RPK.

Thanks Ralph, for the tremendous effort!

Check out the 600 Meter Band Viewer. This allows you to watch signals on the 600 Meter Band between 495 and 510 KHz in 5 minute segments in near real time

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!
