[Discuss-gnuradio] Tutorial on complex signals and receiving SSB no audio

Hello All,

I'm trying S. Katz's tutorial
(http://www.csun.edu/~skatz/katzpage/sdr_project/sdr/grc_tutorial4.pdf)
on SSB and can't seem to get any audio out of the gnuradio-companion
flow graph I've generated. I'm sure the error is mine, but can't
figure out where I made it.

I'm using gnuradio 3.7.13.5 under Linux and have attached my grc file.
If anyone has the time to try it out, you will need to download
ssb_lsb_256k_complex2.dat from
http://www.csun.edu/~skatz/katzpage/sdr_project/sdr/ssb_lsb_256k_complex2.dat.zip
and unzip it, then change the file source in my tutorial4.grc file to
point to the unzipped file.

Thanks in advance,

Chris
