Hello,
I have run into a problem using flow_graph stop(). To test the problem,
I wrote a quick test script that simply sinks a tone to the USRP
(test_tone.py).
Basically this is:
-
class test_tone(gr.flow_graph):
def __init__(self):

Thanks for the suggestion. I dove into the TCP code to try and figure out

Hello all,
I'm working on an Amplitude De-modulator. I have verified the received
signal is: x(t) = m(t)cos(2*pi*base_freq*t).
x(t) --- |multiplier| --- |lowpass filter| --- k*m(t)
cos(2*pi*base_freq*t)
My difficulty is creating the lowpass_filter and complex/float conversions.

I was thinking the same. But then I thought that the USRP is overkill
if you are doing ham type waveforms as they are only 3Khz wide at
mosy. A studio quality computer "sound card" can take 192K samples
per second at 24 bits per channel.. GNU radio software can interface
to a high-end sound car
Hi folks,
I'm a ham that has become interested in SDR in general, and GNU
Radio/USRP. I'm looking to build an SDR that can TX voice (FM & SSB) on
HF/2m/70cm and that could also be a platform for data transmission in
the coming years. I've found a good bit of information on the web
regarding recep
