[amsat-bb] Nothing from ARISSat-1?

Over the past couple of days I've heard ARISSat once. Even on the really high passes (up to 27° on the highest ones) there's just been not a cheep out of it. It must be in full daylight, too.

Has anyone else heard it? I notice my tweetly noise is still there on 145.919MHz, still no idea what that is. It seems weaker today, but maybe that's a weather thing.
