I've just finished a low noise preamplifier prototype based on Avago
MGA62563, and I would like to use it in conjunction with the tvrx - the
device needs 3V @ 60mA, or 5V - is there any place on the board where I
can get such a supply safely?

Good point.
I commented out the offending lines. If you have portaudio and/or jack,
they are easily replaced.
#from gnuradio import audio_portaudio
#from gnuradio import audio_jack
and then remove the comment in front of the
dst = audio_jack.sink
and/or
dst = audio_portaudio.sink

With help of the examples, I was able to get a little bit further. The
portaudio_sink now gets initialized, but it shortly after fails with
an abort trap. The cause is line 167 in audio_portaudio_sink.cc where
d_portaudio_buffer_size is 0. It looks like if

I was looking at the fftsink.py and the plot.py that it uses. Is there a
simple way to plot a graph with everything down under the points also filled
with a colour ? I am trying to see if plot.py has a way to do that.

Thanks.
In general, I think we ought to push the selection of audio
"subsystem" into a preference somewhere. Yes, I know we're missing
that feature right now.
I'm fine that you've modified t

Ok, Eric -- I really understand it now.
Im able to start "dual_tx.py" and "dual_fft.py" and I
can see the two signals ! (I have Tx_A -> Rx_A and
Tx_B -> Rx_B)
I can switch the signals by just swapping mux values
-- nice...
Now it seems trivial, but I can upload the
"dual_fft.py" if is there anyo
No. Let me be clearer...
If you have a DBSRX Rev 2.0 board (what most people have):
Apply your bias voltage to the pin labeled "+" on J100 (the
one closer to the SMA). The other pin on J100
is ground.
Your bias voltage can be up to 30 V, and you

Hi,
I fixed gr_pll_carriertracking.h in gnuradio-core
It had one comma too many on line 41 which broke the build.

Ok. This is closer. I get a few buffers, almost 1 second and then it
goes off the deep end but that is better than before when all I could
get was segmentation fault!
I will look at the callback interface, etc. to see if I see anything.
I already know this pa works because I am using it
