Warning: predictions based on callsign expiration may be incorrect due to government shutdown!

Due to the government shutdown, FCC says that deadlines are extended and it seems that callsigns are not expiring on schedule. See FCC public notice DA 25-943 for details on the impact of the shutdown at the FCC. It is expected that many callsigns will not be available on the normal schedule.
