A radio educator asks the FCC to keep AST SpaceMobile out of the 430-440 MHz ham band

Rosalie Ann White, a former schoolteacher and Amateur Extra Class licensee with call sign K1STO, says she read over 150 filed comments in FCC docket 25-201 before submitting her own opposition to AST & Science's modification application. The request, as her filing describes it, would authorize an additional 243 satellites with telemetry, tracking and command operations in the 430-440 MHz amateur band. She calls that "appalling," writing that the segment AST wants "is used all the time for RF exploration and educational research done by students considering aerospace and technology careers."

Her filing joins a crowded record. Docket 25-201 holds 145 filings from 106 distinct parties, including 94 comments, 8 oppositions, and 3 petitions, with SpaceX, T-Mobile, CTIA, and the Competitive Carriers Association among the filers. Her bluntest objection targets the size of the spectrum request itself: 10 MHz.

"And why 10 MHz? They must be expecting their transmissions to not be clean; they must expect the signal to be illegally wide."
