The deadline for comments on this is tomorrow. This is very concerning.
They have already been issued their experimental license that expires on

Wow, that didn't take long: The FCC wants to grant permission to use the
430 to 440 MHz range for commercial satellite control applications. Once
granted, Amateur Radio could become a source of interference, and
subsequently our allocation might be withdrawn.

FCC Proceedings and Public Comment:

The FCC's Space Bureau has accepted AST SpaceMobile's application
for filing and is soliciting public comments on the proposed use of the
band. Interested parties can submit comments through the FCC's
Electronic Comment Filing System (ECFS) by July 21 at:

https://www.fcc.gov/ecfs/filings/express?proceeding[name]=25-201

The FCC will consider all filed comments and evidence before making
a decision regarding the allocation of the 430-440 MHz

Dear Sirs, I am writing to express my concerns regarding the AST 
application for the use of
the 430-440 MHz spectrum fo r Telemetry, Tracking, and Command (TT&C). 
This frequency
range is already allocated on a primary basis in Region 1 and is 
actively used by various
entities, including amateur radio operators, amateur satellite services, 
etc. Amateur radio
acts as a vital resource for emergency communications and 
experimentation, while amateur
satellites support educational and scientific advancements. It is 
crucial for the Commission
to consider the potential implications of granting AST's application, as 
it could disrupt the
established uses of this spectrum and undermine the important functions 
they serve. I urge
the Commission to prioritize the preservation of these existing services 
and to explore
alternative spectrum allocations for AST’s requirements. Thank you for 
your attention to
this matter. Yours faithfully, <<>>
