Hello,
Months ago I bought a USRP. Nice piece of Hardware but I did not really
dive into GNURadio until this weekend. Still learning about it. I am
also busy maintaining software that decodes Trunked Radio Control
Channels and LTR variants like NTS Passport.
I am a Boston area Ham and member o

Hi Eric,
I get it now, 64/4 Msps = 16 Msps = 32MBps ==> each sample has to be
2 bytes i.e. 8 bit I&Q.
Can we make usrp_spectrum_sense.py to run with 8 bit I&Q instead of 16
bit I&Q? I mean, If I want to be able to observe a chunk of 16Mhz at
once (if possible, even more), is there something I c

Yes, we do it all the time.
Though generally speaking, we like to take advantage of the

You would have to modify the verilog, but it is definitely possible.

Hi,
is it possible to tune the intermediate frequency of the USRP before
quantization and then make a base band translation on software?

Hello everyone,
My understanding is that the decimation value for the fpga has to be
between [4, 256]. In usrp_spectrum_sense.py, when I set the decimation
values to 16 or 8 (spanning 4Mhz and 8Mhz chunk at once), then
m.data[0] ...m.data[255] print out fine. However, when I set the
decimation to
Hey All,
I have figured out how to program signal processing blocks in c++, and get
them to run in python, but I am looking at creating a source that will read
from a wx slider bar and scale that value and pass it into my other signal
processing blocks. So I need to set up a source in python, bu
Hi Jonathan,
Just to be sure, I checked out a new version and followed the steps
again. It works!!
The Makefile points to the correct swig. May be the problem was not
doing a distclean.
Thanks so much!

Did it actually rebuild any files? Just being paranoid, I'd do a 'make
distclean' an
Hi Jonathan,
I installed swig-1.3.31 and ran "bootstrap, configure, make and make
check", but I get the same errors again. Here is what my system says:
