Hi all,
I'm trying to use OSSIE.0.7.1 with new release of gnuradio (3.2).
The building of gnuradio it's ok, but when I attempt to build OSSIE, the
make of USRP component returns this error:
if g++ -DPACKAGE_NAME=\USRP\ -DPACKAGE_TARNAME=\usrp\
-DPACKAGE_VERSION=\0.6.2\ -DPACKAGE_STRING=\USRP\
Hello,
I asked this question before, but no one answered yet -- maybe it was
not recognized out of several questions.
Anyway, I have two related questions with usrp2.

Decimation
I see the minimum decimation rate of usrp2 is still 4 with GRC, and
wonder if there
Is any method to obtain the RSSI value for USRP2?

Thanks a lot Tom for your help. I now understand how Costas loop operates.
After all the tests that I did following your suggestions I was able to find
the answer for a lot of my unanswered questions.
Thanks again,
Ali

Hi,
I have another question regarding this. I sunk the output from the Costas
onto FFTsink and got this.

Are the peaks that appear on this the lower and upper sidebands of the data
signal?
Thanks,

I have achieved this by going for a multiple flow graph

Interpolation
Also, I found that the observed spectrum of my usrp2 is very choppy with
the interpolation lower than 10, which means my baseband sampling rate
can be only 10Msps. So, is this the limitation with usrp2? or are there
any ways to lower this interpolation rate
We are pleased to announce that the USRP2 is now for sale!
