Checking through different recordings of the quake...I came across Mt. Redoubt’s rso recorder.
Not a single hint of that big quake....kinda odd. Wonder what they have it set on...lol

From the link you posted:
October 4, 2011: The signals from station RSO is currently troubled with radio interference from an unknown source. Station RSO is located 3 km (2 miles) south of the Redoubt summit and can be very sensitive to activity at the summit. A map showing the location of RSO and other Redoubt seismic stations is available at http://www.avo.alaska.edu/image.php?id=16308.
Ha! Typical government workers, lol... Takes 'em forever to do something. Reminds me of the "Daily Update" on the JPL Mars Curiosity page: "October 10, 2012 - Work Resumes with First Scooped Sample."
