RAC Bulletin 2014-004E - RBR-4 Confirms Access to 137 Khz.*
2014-03-15

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...g/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)".

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.

Thanks to Richard Ferch, VE3KI and Jim Dean, VE3IQ.
