With the ATSC stuff, there's a little variation depending on input
data, but not much.  

Take a look at gnuradio/src/gnu/atsc/test_full_loopback.  It generates
fake data and runs it through the transmitter and then the output of
that into the receiver.  I suggest concentrating on
the atsc_rx code running with the -s 20 -L flags.  They enable
20MS/sec input processing and the LMS equalizer.  Those are the usual
options.
