Hi, guys
I updated my GNU radio to the 2.5 version. But I met
the following "segmentation fault" error when I tried
to run wfm_rcv_gui.py
usrp_standard_rx::set_decim_rate: WARNING rates > 128
result in incorrect gain.
>>> gr_fir_fff: using SSE
Segmentation fault
Can anyone provide some suggestio

Hi all,
There was some talk a few weeks back on creating a file format in which
there's a header storing info like the sample rate, capture freq,
decimation, etc.
I would like to create such a file, but would like to store some small
amount of data once per work cycle. The idea is to constantly

Since the inputs and outputs on the BasicTX and BasicRX are transformer-coupled,
you can not pass DC. The low end is about 100 kHz. You can make it much lower

Generating good white noise in real time with this bandwidth is a problem; it
takes a lot of processing, particularly to get a good distribution with
gaussian tails many sigma out. If you're going to redesign the guts of the
FPGA, I'd suggest feeding an external white noise generator into one o

It turns out making a psk31 idle is really simple:
samp_freq = 48000
pskmod = 31.25 /2
bpsk = gr.sig_source_f(samp_freq,gr.GR_COS_WAVE,pskmod,1,0)
tone = gr.sig_source_f(sam
