John,
You need to run: "./pybombs env"
and then follow the instructions about using the "source" command to set
the environment variables.
Once this is done type "gnuradio-companion" in the terminal to launch GRC.

If you make an FFT block for each rtl-sdr source you can then interleave
them all together and take your pick using the 'M in N' block. At the edges
of each rtl-sdr frequency it will probably get quite messy as the clocks
are not synchronised.
An example of the use of the FFT and 'M in N' blocks i
The delay block works in samples so to get seconds you have to multiply the
sample rate by the number of seconds you want to be delayed by.

To shift just the phase you can use the 'Complex To Float' block in GRC
which separates the stream into real and imaginary components. After
adding the delay block in line with the imaginary component you can then
recombine the stream by using the 'Float To Complex' block.

If you want 1e6 Hz (1MHz) of receive bandwidth at a center frequency of
2.4e9 Hz (2.4GHz) then you just set the center frequency to 2.4e9 and
sample rate to 1e6 in the UHD source block in GRC.

Hi,
The WBX frequency stability is determined by the accuracy of the USRP clock
signal. For example, the USRP2 has a 100MHz internal clock which can be
locked to a 10MHz external source such as GPSDO for better frequency
stability.

Hi,
You have to call tb.stop() before the tb.wait(), not the other way around
like you mentioned:
tb.stop()
tb.wait()
The tb.wait() is to make sure the flowgraph has fully stopped before doing
anything else.

Hi Azim,
This seems to work for me, just update the function on line 265 with the
following two lines:
power_db = float(20*math.log10(power))
print freq, power, power_db

Hi Sajjad,
Try tcping if ping doesn't do what you want:

Hi Sajjad,
Ignore the last message! TCP Traceroute is actually what you are after:

Hi,
I'm having the same trouble on Ubuntu 12.04 LTS x64 after playing with the
AMD/ATI drivers.
The quick solution is to add the following to ~/.gnuradio/config.conf :

Hi,
I believe that error is due to me experimenting with the uhd_fft 'click on
fft to change frequency' feature. Are you using the current master branch
as this contains Marcus Leech's fix for it.

The build GNU Radio script from Marcus Leech is highly recommended as it
also does the UHD:

Hi,
Go into the gr-osmosdr directory and type 'make'. When the build fails
again you should be able to pinpoint the problem from the error message
produced.

Using the lo_offset on the TX side prevents local oscilator leakage on the
TX frequency, to prevent giving the false impression that it is
transmitting after stopping the flowgraph.

I've just looked at the git log and I am also using the same version as you:

I am using Ubuntu 12.04 LTS x64 with a Quad Core i7/8GB Ram and GNU

Hi Zeeshan,
If you attach your code I can take a look for you.
Assuming you have 2 x USRP2, have you tried a MIMO cable/10MHz clock source
to synchronise clocks between transmitter and receiver?
