Hi,
Why is the d_phase equation different in these two files?
d_phase += d_alpha*phase_error; // In gr_mpsk_receiver.cc
and
d_phase = d_phase + d_freq + d_alpha * error; // In gr_costas_loop.cc
The d_freq term is omitted and I don't understand why.
Thanks,
Ali
HI all,
I run the FM stereo example with Ubuntu 8.04 and gnuradio 3.1.3
but now I try to run gnu on fedora 10 with gnuradio 3.2
I got the error like
File "radiogui.py", line 31, in
from gnuradio import blks
ImportError: cannot import name blks
I copy the FM stereo file in gnu directory still

Installed GNU radio 3.1.1 last friday on Ubuntu 8.04(hardy) and ran
tests for maximum throughput between host and USRP using
usrp_benchmark_usb.py. Worked fine on friday.
Not working today. Getting following error.

Hi,
You have to explain well in order to get help, for example you said :
[ for 200ms cycle time my array look like [27, 200, 27, 27, 27, 27, 276, 27],
here count = 27, other values are actually some errors ]
What is [my array]? how we suppose that we know your array? And what are these
numbe

Its no bug in GRC. It seems the qam8 demodulator is empty:

I'm in the process of verifying that my MacPorts Portfiles work with
the 3.2 release -- before releasing them "into the wild" -- by
updating them with the actual release requirements (e.g., no inband,
pmt, mblock, atsc, ). During this process, I'm come upon a bug in the
3.2 release tarball
Hello,
I would like to capture signals using the USRP1 (rev 4.5) with DBSRX. For
the first test I am using CW signal from generator at 1.501GHz, 0 dBm
(verified to be precise). To capture the signal I use the usrp_rx_cfile.py
(usrp_rx_cfile.py -R a -d 8 -f 1.500G -N 40064 -s -g 45 usrp.dat)

Is there a way that I can view some of the data samples when the GNU Radio
is running FM radio? That way I would be able to compare the actual data
values that should be coming, and the values that I am getting through the
interface I am using.

I have successfully run gnuradio on linux/windows. I am running the
example usrp_wfm_rcv.py. i want to look at few of the data samples
