The prospect of a USA constellation of 240 commercial satellites that would use 430 to 440MHz for wideband control and telemetry, has prompted an unprecedented response from the amateur radio community to a Federal Communications Commission, or FCC, consultation. FCC Proceeding 25-201 would see AST SpaceMobile utilise much of 430 to 440MHz for downlinks as well as a series of ground stations around the world.
The RSGB and several other IARU member societies, along with the ARRL and over 2,000 individuals, have submitted comments to this consultation. The IARU itself has also issued a statement on the matter. Links for this, including the RSGB response, can be found on the RSGB website. Go to rsgb.org/spectrumforum and then choose the ‘Papers and consultations’ option in the righthand menu. Following the main submission deadline of the 21st of July, the FCC process has further phases to go through.
