If you are a ham and doesn't want to spend too much, I would recommend
Peaberry SDR V2 (and it's not just receiver it's 4-band tranceiver and
it doesn't require sound card opposed to softrock). It will cost you
$150 as a kit (quite easy to build) or $250 built.

that.

The ctrlport related warnings are ok (they are but warnings), the
segfault is bad; as you might imagine, it's not the easiest thing to debug.
However, I really hope you uninstalled Ubuntu's gnuradio package first,
before using build-gnuradio?
Also, you'll *still* have to install libhackrf and gr-os
One thing I tried was "wget http://www.sbrac.org/files/build-gnuradio &&
chmod a+x ./build-gnuradio && ./build-gnuradio"
After almost 4 hours it completed. Didn't notice any errors during the
build.
However now when I run gnuradio-companion I get:
Warning: Block key "blocks_crtlport_monitor"
First thing, get rid of the throttle. It is only needed in
*simulations*. In graphs with real hardware, everything is "paced" by
the hardware.

How long it takes for the Metafile Sink to began recording data?
I have a "No GUI" script that is a simple USRP source, throttle, and
metafile sink. All have a 1M sample rates; the metafile sink has a relative
rate of change of 1, 1M segment size, and have a detached header.
I start my script up
-8dBm may, or may not, have damaged either of the the two LNA stages on
the WBX.
"Modern" WBXen have TVS and limiter diodes in front of both stages to
try to ameliorate laboratory accident consequences, but they offer no
firm guarantees.
Nearly all of the receivers on USRP daughtercards are
1) What you are doing is correct. What's the power of your signal
generator? I was using -40 dBm, and as Marcus says, that is strong, but
you'll need to have a good SNR since the noise bandwidth is ~250 kHz.
Several posts ago you stated running -8 dBm into the WBX. You may have
damaged the WBX
Just as the GCC C compiler doesn't include every program that has ever
been written with it, nor every library that has ever been written with
it, so too, the "gnuradio" package only includes the core Gnu Radio
functionality. Just as other packages have "plug-ins", Gnu Radio
organizes many of it

The gnuradio package doesn't contain every GNU Radio module that exists ;)
you still need to install gr-osmosdr and libhackrf; see my last mail[1].

You need to ./configure once more.
If that doesn't help, git clean -xdf will clean up your source tree,
and you can start with a "clean" build.

I am trying to find the osmocom and/or RTL-SDR sources.
I'm running GNU Radio Companion 3.7.2.1
In GNC I did a search for osmocom and RTL-SDR and nothing was found.
What didn't I setup correctly during the "sudo apt-get install gnuradio"

The problem of last mail (in install 3.3.0 with Ubuntu 9.10) is resolved
installing libtool.
Now I have a problem with libtool version in make:

I used the ofdm transmitter receiver blocks to create a simple system as shown

Hi
Thank you for your note.
My questions here are just based on my previous measurements and your last
mail. kindly clarify the same.
1) Is it possible that different USRPN210 devices with WBX boards have the
different calibration factors. I set the channel gain to 0 and still get :
