Hi Przemek,
I must admit I'm not able to reproduce the issue –
>>> from gnuradio import analog
>>> analog.sig_source_c(1,analog.GR_SIN_WAVE, 0.1,1,1)
works just fine, and the literal 1 is definitively an int. What does
print type(offset_Value)
say in your code?
I guess you might want to us
Hello All !
I am Ravi Sharan and I am currently pursuing my M.Tech in EE from

This may help. In line 55 of CMakeLists.txt, add VOLK. Like so:

Hi Pavan,
Yes, you are correct, this test won't show phase alignment. The most common
checks for phase alignment need a receiver able to do two simultaneous
channels, such as a high bandwidth oscilloscope, another N210/SBX that can
be setup the same as your transmitter pairing, or an X300 series U
Hi Derek,
That makes sense. I will put a combiner and try this. However, now the test
is a bit different, right? The only way I could tell that the transmitters
are transmitting at the same time is if the power level is double what it
used to be, assuming they are actually fully in phase. Is there

I would like to set offset to signal source component in construktor;

Hi Pavan,
I'm sorry, I didn't read your cabling closely enough or I would have
noticed this before. If you only have one SBX in the receive N210, then you
only have one possible receive channel! That is why you are seeing the
error that RX channel 1 (remember they're 0 indexed) is out of range. On

OFDM containing BPSK symbols is not a PSK modulation in time domain; so
you're using the wrong estimator as is.

Thanks, Tom.
Okay, every once in a while I guess correctly.
I will look at the logging infrastructure as you suggest. For now, since I do
all my OOT dev on Linux, I will be okay. The issue came up when I wanted to
make sure the OOT module works on a second box, and that happened to be OS X.

You can just add a bigger file-backed swap partition. From my experience
building on the Pi3, the time that it spends building stuff at a high mem
requirement is low. This will allow it to not die on a burst of mem needed,
but allow the build to continue with fairly little oversight.

Hi,
I have a GRC project with multiple Tag Debug blocks. Under Linux, the output
appears in the console as one would expect. However, under OS X, the characters
of the output appear to be “multiplexed” in some way. The problem goes away if
I have only one Tag Debug block enabled. Out of 4 diffe

I’m very happy to introduce myself as one of the GSoC students this year

That's what i thought the message strobe does. I tried different times

Hi Marcus,
Thanks for your response. I realized that I have a more fundamental
problem before optimizing this project:

Hi Dan,
given you want to sweep within one TX bandwidth (which is the complex
sampling rate), something like the following flow graph fed into a USRP
sink tuned to the right center frequency:
Sweeping FG
If you want your sweep to span more than the sampling rate, things get
more complicated.
