Alternative to myIBFS for FCC International Bureau Filings

MyIFBS is the International Bureau Filing System for International Affairs, Sattelite Filings, and other space-related filings.
Unfortunately, The FCC IBFS does not have any RSS feed capability and has an otherwise very poor user interface for this data.

The site FCC.report has mirrored the IBFS database and enabled a better UI as well as RSS feed capability. You can view the improved version of myIBFS here.
