Yes, am looking at the source lists now
 https://www.mrao.cam.ac.uk/projects/surveys/6C/data/README
  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..

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.
