For the second time in a week or so, Radio Australia was having
digital fidgits. Between about 12:40 UTC and 15:00 UTC, there were
five second long drop outs, some silent, some starting with a funny
klaxon buzz noise. Since the good audio lasted between two seconds
to only a portion of a minute, it made "interesting listening".

I was hearing the same thing yesterday from Australia on 9580, and this
morning heard exactly the same thing from Radio Canada International on
17820. I thought my radio was dying.
