Canadian Amateur Radio access to 137 Khz

Industry Canada has approved access by Canadian radio amateurs to the Low Frequency (LF) band 135.7 - 137.8 kHz, subject to certain conditions.

The Revised Canadian Table of Frequency Allocations, promulgated in December 2009 to incorporate changes arising from decisions taken at World Radiocommunication Conference (WRC) 2007, permits amateur radio use on a Secondary basis subject to Footnote 5.67A.

The Footnote states: "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)".

Industry Canada has advised that Canadian radio amateurs may now use the band and that  Schedule I of RBR-4 Standards for the Operation of Stations in the  Amateur Radio Service will be amended in due course.
