Hams will not be able to access the FCC's amateur radio licensing database or file comments on rulemaking proposals beginning at 6 PM EDT on Wednesday, September 2, and possibly extending through the Labor Day weekend or beyond.
In an announcement on September 1, the FCC said the planned shutdown of its interactive public-access web applications - including the Universal Licensing System (ULS) and Electronic Comment Filing System (ECFS)- is necessary to permit and upgrade to its "legacy IT systems."
During this shutdown, hams will not be able to look up call signs on the FCC database or file license renewals or updates. In addition, new licenses and upgrades will not be posted during this period.
According to the FCC announcement, "We will work to have these web applications upgraded and available again by the morning of Tuesday, September 8." The FCC says it does not plan to release any official documents during this planned shutdown.
