Re: [Discuss-gnuradio] DVB-T Reception Problem

It looks like it's doing a little better. I would try deleting (or
bypassing) that Multiply Const block. It may actually be causing trouble
for the gr-isdbt OFDM acquisition block.

If you do get things running, the viterbi_decoder block needs to be set
to Code rate 2/3.
