KALW IBOC off?

KKUP is now being heard clearly again in San Francisco, which probably means that KALW has its IBOC shut off. KALW was one of the first stations in the Bay Area to start running HD (If I'm not mistaken, the first was KFOG) It is unknown if this is a equitment failure, or if its off for good to save on the power bill. Many AMs in SF have had their IBOC going on and off, and KGO quietly turned their's off for good last year. KCBS's HD signal is pretty consistant, but KNEW and KKGN's IBOC goes off and on.
