The first question I've already found the solution, please just advice for
the second part.

See how the logpwrfft in gnuradio adjusts for different windows and fft
lengths:

Hello
I wonder someone can help me out. While testing this code, the media with the
different size of fft shows different value. I would like to know how I can get
the same media value regardless of using different fft size.
Thanks,

Hello,
Can gr-sounder run on Basic daughter board? If not, what's the problem?
(gr-sounder said "the boards may be standalone LFTX/LFRXs or RFX
daughterboards", but what the reasons will be?)
Thanks in advanced

I've tried different gains on both boards, but it doesn't make a difference.
The frequency I am tuning to is 560.31 MHz, which is below the specified
frequency range of the DBSRX. My DBSRX tunes to that frequency without any
errors, but perhaps tuning it out of range it is causing a problem. I w
I thought the same thing when I first saw it, but reducing the gain doesn't
make a difference. At the link below is a screenshot of the result of lowering
the TVRX's gain from 30 to 10. The gain is low enough that what I assume is a
DC-offset from the ADC can be seen in the center of the plot.

You're probably trying to start "In the past". That is, your start_at

Thank you Eric!
We are glad that this is on your 'short list', we look forward to see the
results and try it out (assume the changes will happen in your branch?).
We are especially interested in synchronized message passing and the ability to
tweak parameters at runtime, perhaps even alter bloc

Hi,
I've been using the latest git version of gnuradio and trying to get Doug's
start_rx_streaming_at patch (now merged with the git version) to work. I
don't think there's any support via gr-usrp2 so I've modified
