Through the release of this paper, Industry Canada is hereby initiating a consultation on the addition of a footnote to the Canadian Table of Frequency Allocations to allow the amateur radio service (ARS) to operate on six frequencies in the 5 MHz range, on a no-protection, no-interference basis. Industry Canada is also consulting on possible amendments to Regulation by Reference RBR-4, Standards for the Operation of Radio Stations in the Amateur Radio Service. These amendments specify emission designators, transmit power and occupied bandwidth for ARS transmissions on these frequencies.
Industry Canada is seeking comments on the issues raised in this paper, in accordance with Canada Gazette notice SMSE-010-12. Submissions must be received no later than June 12, 2012 to ensure consideration.
The Minister of Industry, through the Department of Industry Act, the Radiocommunication Act and the Radiocommunication Regulations, with due regard to the objectives of the Telecommunications Act, is responsible for spectrum management in Canada. As such, the Minister is responsible for developing national policies and goals for spectrum utilization and ensuring effective management of the radio frequency spectrum resource.
In developing a policy and licensing framework to make additional spectrum available, Industry Canada takes into consideration the need to provide spectrum access for new services and technologies, the impacts of such a framework on all stakeholders, and the Spectrum Policy Framework for Canada (SPFC) policy objective to maximize the social benefits that Canadians derive from the use of the radio frequency spectrum.
Industry Canada believes that amateur radio should be readily accessible to Canadians, in accordance with the SPFC guideline of making spectrum available for a range of services that are in the public interest.
The band 5250-5450 kHz is allocated to the Fixed Service and the Mobile Service (except aeronautical mobile service), on a co-primary basis in Canada, as shown in Table 3.1. This band is also allocated to the Fixed and Mobile services (except aeronautical mobile service), on a co-primary basis in all three Regions of the International Telecommunication Union. Currently, there is no domestic or international allocation to the ARS in this range.

A survey of the band 5250-5450 kHz revealed that there are numerous licensees. However, there have been no reported cases of interference to these licensees from ARS operations in other countries that have licensed ARS use of the band.
In 2010, the Radio Amateurs of Canada (RAC) approached Industry Canada and requested the use of five centre frequencies in the 5 MHz band, namely 5332 kHz, 5348 kHz, 5358.5 kHz, 5373 kHz and 5405 kHz. The RAC stated that the use of these frequencies would allow for more reliable communications during emergency operations compared with other amateur bands at 3 and 7 MHz, which can be heavily impacted by ionospheric disturbances. The RAC indicated that the propagation characteristics in the 5 MHz frequency range allow for both local and interprovincial communications.
The RAC also highlighted that the U.S. amateur radio community has had access to these frequencies for several years. Harmonizing frequency use would allow Canadian radio amateurs to conduct regional emergency communications on a coordinated basis with U.S. radio amateurs. Finally, the RAC noted that many administrations around the world have authorized the use of the frequency 5405 kHz to radio amateurs.
The RAC also requested the use of two additional frequencies, namely 5319 kHz and 5329 kHz, for domestic use in Canada. The RAC underscored that access to these two frequencies would minimize the potential for interference from other users worldwide when Canadian amateurs are communicating in times of local and regional emergencies.
The U.S. Federal Communications Commission (FCC) recently released amendments to U.S. domestic rules governing ARS use of the band 5250-5450 kHz.1 The U.S. ARS community has had access to the frequencies 5332 kHz, 5348 kHz, 5373 kHz and 5405 kHz since 2003, and was recently authorized to use the frequency 5358.5 kHz. As well, the FCC allowed an increase in the maximum authorized effective radiated power in the band from 50 W to 100 W peak envelope power (PEP) and authorized the following emission types and designators: telephony (2K80J3E), data (2K80J2D), Radio Teletype (RTTY) (60H0J2B), and Continuous Wave (CW) (150HA1A). Finally, the FCC required that amateur radio operators ensure that their transmissions occupy only 2.8 kHz centred on each of the authorized frequencies. U.S. radio amateurs must not cause harmful interference to other authorized stations.
The band 5250-5450 kHz is heavily used by federal agencies in the United States. It should be noted that these frequencies and technical rules were carefully selected by both the National Telecommunications and Information Administration (NTIA) and the FCC after studying the interference potential to primary users in the band.2 Therefore, harmonizing Canadian frequency use and technical rules with those of the United States would diminish the risk of interference to U.S. primary users.
After conducting a review of domestic and international use of the seven frequencies requested by the RAC, Industry Canada determined that the frequency 5319 kHz is unavailable for use. However, the remaining six frequencies could be made available to the ARS on a no-protection, no-interference basis.
The Department invites comments on the following:
- Should Industry Canada allow amateur radio operators to use the five frequencies 5332 kHz, 5348 kHz, 5358.5 kHz, 5373 kHz and 5405 kHz, which are harmonized with U.S. amateur use, on a no-protection, no-interference basis? Transmissions would be restricted to a 2.8 kHz bandwidth centred on each of these frequencies.
- Should Industry Canada harmonize emission modes and designators with those specified in the United States for these five frequencies – i.e. telephony (2K80J3E), data (2K80J2D), RTTY (60H0J2B) and CW (150HA1A)?
- Should Industry Canada specify a maximum effective radiated power of 100 W peak envelope power?
- Should Industry Canada allow Canadian amateurs access to the 5329 kHz frequency for domestic communications only? Transmissions would be restricted to a 2.8 kHz bandwidth centred on this frequency.
- Should Industry Canada specify emission designators and peak envelope power for this additional frequency? If so, what should these be?
Industry Canada is proposing to add a new footnote to the Canadian Table of Frequency Allocations, as follows, to allow for the use of the band by the ARS as shown in Table 7.1. This footnote would allow the ARS to operate on no-protection, no-interference basis on these frequencies and would require the ARS to protect incumbent services, both domestically and internationally.

CXX (CAN-12): In the band 5250-5450 kHz, the amateur service may transmit only on the six centre frequencies: 5329 kHz, 5332 kHz, 5348 kHz, 5358.5 kHz, 5373 kHz, and 5405 kHz. Amateur service operators may not occupy more than 2.8 kHz centred on these six frequencies. Such use is not in accordance with international frequency allocations. Canadian amateur operations shall not cause interference to fixed and mobile operations in Canada or in other administrations and, if such interference occurs, the amateur service may be required to cease operations. The amateur service in Canada may not claim protection from interference by the fixed and mobile operations of other administrations.
- Comments are invited on this proposal to update the Canadian Table of Frequency Allocations.
Industry Canada is also proposing consequential amendments to RBR-4, Standards for the Operation of Radio Stations in the Amateur Radio Service, as follows.
