n-QAM

Hi
 I am new to gnuradio, so maybe a trivial question: I couldn't find any qam demodulation
block for use from python scripts, does it exist?  I have read somewhere about HDTV (not realtime)
reception by gnuradio, and DVB-T uses QAM, so I suppose it must exist, where can I find it?

Thanks, Jiri

I wrote the QAM modulators a while back, but I've yet to find the time
to build a proper receiver for them. There was some work to do this, but
it never got merged back into the trunk that I know of.  I won't be able
to get to it for a while, either (this big, black cloud named
"dissertation" has to be removed from over my head first), so any help
would be greatly appreciated.

Tom
