The “Was It ET?” Signal

Daily Grail reader Andreas writes:

My name is Andreas. I am running a German news-site on paranormal and fortean issues (not unlike yours) and thought you might be interested in my news article about an unknown signal detected by Australian SETI astronomers. My article is also the only one (so far) that features the print out of the detected signal

The hand-written note on the readout certainly evokes the famous 1977 ‘Wow!’ SETI signal (though not half as snappy for newspaper copy). But again, without repetition, will we ever know its origin (without the help of S.R. Hadden)?
