Yes, am looking at the source lists now

  no attempt at demodulation as far as I can see.
A lot happened as to modulation since the 1993
Also with all that quantum stuff we may get better sensitivity these days..

Summary:
  Researchers have announced a groundbreaking study using the Murchison Widefield Array (MWA) in Western Australia.
  The research is the first to search for signs of alien technology in galaxies beyond our own,
  focusing on low radio frequencies (100 MHz).
  This new approach looks at distant galaxies,
  making it one of the most detailed searches for super civilizations -- those more advanced than ours.
 
Would be interesting to hear their music :-)

Don't get your hopes up. The best chance is relatively nearby stars in
our own galaxy - might just have enough signal to noise then if we catch
them between inventing the thermionic valve and discovering spread
spectrum transmission (which looks like noise anyway).

We, earthlings, make so many RF noises... as do our spacecraft.
Voyager is still calling home I think.
There could be alien radio probes on their way.
