The FCC has suspended issuance of new or renewed amateur licenses. Hams whose licenses expire during the course of the government shutdown will have to use their own judgment as to whether to keep operating. In the past, when various events have delayed the issuance of licenses, the FCC has permitted amateurs who have filed their renewal applications in a timely manner to continue operating until their renewals are processed. However, no one from the FCC has been available in this instance to confirm whether that will be the policy this time.
The U.S. federal government suspended most operations on October 1, the start of the government's new fiscal year, after Congress and the President could not agree on terms of a budget resolution. The U.S. Constitution gives Congress the primary responsibility for appropriating money for government operations.
