Hi, thanks you for your reply.
Tx side it's all ok.
The problem is on Rx side,
Using Oscilloscope with usrp_fft.py or saving samples
on disk i noticed all packet are transmitted. This is true using high value of
interpolation/decimation factor (very low bit rate).
What do you think about

Hi Eric,
Thanks a ton for the reply. My main concern is not that the frequency
offset is high enough but that it changes pretty often (every time I run
a new run) which makes it difficult for repeatability.
So is there a way in software where I can make sure that the frequency
offset is

If I place some output statements in the destructor and flush the output
stream, I never see the statements. If I set a breakpoint in the
destructor using GDB, the breakpoint is never reached. This is in the
top most block. I've tried it in several of the inband applications
Hi all,
Is the destructor of classes instantiated in m-blocks not guaranteed
when using shutdown_all()?

They should all be called. However, if an mblock is blocked in the
kernel we currently don't blast it out of the system call,

I've recently tried out the synthesis_filterbank method provided in
filterbank.py and received unexpected results. I'm trying to use the
filterbank to create one signal from multiple baseband signals. When I use
two signals to create one output, I can see both signals using the FFT sink.

Hi eric,
Thanks for the reply, i have connected it to the
channel filters, i trying to do an estimate on
wireless channel coefficient. Therefore i'm trying to
capture the complex data received before
de-modulation. I havent have much success using vector
sink even when i set a range for the data
