July 25, 2025 – Ottawa, Ontario, Canada

Radio Amateurs of Canada (RAC) has taken note of the concerns raised by Canadian and international Amateurs regarding a proposal submitted to the US Federal Communications Commission (FCC) by AST, a US-based company.

The proposal seeks limited authorization to use the 430 MHz to 440 MHz spectrum – including other non-Amateur bands – for satellite telemetry, tracking and control (TT&C) functions during unspecified emergency scenarios.

RAC was aware of this proceeding, designated as FCC Docket 25-201 and opted not to comment during the initial submission phase. This decision aligns with guidance received from our US counterpart, the American Radio Relay League (ARRL), who has now submitted their formal comments.

RAC intends to participate during the reply phase of this proceeding, which concludes on August 5, 2025. We will coordinate closely with the ARRL to ensure our response is both complementary and constructive. Our shared goal is to uphold and defend Amateur Radio access to the 430-440 MHz band.

RAC has also consulted with Innovation, Science and Economic Development Canada (ISED), ensuring that Canadian regulatory authorities are aware of the proposal and the concerns voiced by Canadian Amateurs.

The Amateur community has expressed strong reservations about potential interference with weak-signal activity in the vicinity of 432 MHz, as well as with Amateur satellites operating between 435 MHz and 438 MHz.

While some online commentary has exaggerated the implications of the proposal – including claims that Amateur access to this spectrum is in jeopardy – it is important to note that such assertions are unfounded.

Nevertheless, RAC remains committed to defending the interests of Canadian Amateurs and will formally respond to the FCC in the upcoming phase of the proceeding.
