John,

You may also want to try increasing the decimation (lowering the
bandwidth); this may help cut some noise. Change the -d flag to 32 or
64.

Subject: Re: [Discuss-gnuradio] NTSC Receiver

I see your using an over the air channel. I’ve only tested with cable
tv. The simple detector probably can’t deal with the noise found in that
signal. I will connect an antenna to my board tonight and look in to
that. If you happen to have cable (or the VHF output of a TV receiver)
you can try that for now.

Thanks,
Daniel

TV Channel 15 should be 476 - 482, and the Video at 477.25, which
I see on my FFT display of the channel.
