RBR-4 confirms access to 137 Khz

Industry Canada approved access by Canadian radio amateurs to the Low
Frequency (LF) band 135.7 -137.8 kHz, subject to certain conditions in
 late 2009. This was a direct result of implementing changes from the
World Radiocommunication Conference (WRC) 2007, which added amateur
use of this spectrum on a Secondary basis.

This has now been included in the newly updated RBR-4 Standards for
the Operation of Stations in the Amateur Radio Service.
(http://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf10650.html)

Canadian amateurs are reminded that the maximum emission bandwidth in
this band is 100Hz (e.g. cw, BPSK31, BPSK63, etc.) as well as a
maximum EIRP of 1 watt. These conditions are found in Footnote 5.67A:
"Stations in the amateur service using frequencies in the band
135.7-137.8 kHz shall not exceed a maximum radiated power of 1 W
(EIRP) and shall not cause harmful interference to stations of the
radionavigation service operating in countries listed in No. 5.67.
(WRC-07)".

Radio Amateurs of Canada (RAC) welcomes reports of activities in this
band, especially reports of DX achieved and useful operating tips.
We are asking those active on this band to consider writing articles
for TCA to help other amateurs get started on LF, given the large
differences in LF antennas, and the need for homebrew transmitters,
receivers, and/or transverters. Insights into propagation and other LF
operating tips are also requested.
