This question is probably more suited to the AirProbe mailing list.

Subject: [Discuss-gnuradio] run AirProbe with first_usrp_decim_
Hi all,
I am learning AirProbe to decode the GSM signal.
OS: fedora 9 (2.6.25.9)
GnuRadio:3.1.3
Following the link,
https://svn.berlin.ccc.de/projects/airprobe/wiki/WorkingWithTheUSRP, I
ran ./go.sh first_usrp_decim_112.cfile, but the GSM scanner showed
nothing as the attachment.
I have no idea

Jane,
Hi Tom,
I tried it out but its not working. I am always getting an S which means
overrun. I am attaching the all the files that I have used to make USRP2
work as receiver. I have made no changes to benchmark_tx.py as it is used
for USRP1 and its working correctly.
benchmark_rx.py:

They are,

Yes.

Hi list,
I have recently begun to see a lot of tx_underrun in my applications. At
first I thought it was due to me not setting realtime- scheduling
properly (which I did), then I thought it might have something to do
with recent fusb_* updates from gnuradio (which it didn't, since I
downgrade

This is fine.

This is not. You need to set your power settings to "performance" mode
to keep your clock at 2.2GHz.

Hello everyone,
maybe someone can help me with this:
I try to use two RFX2400 simultaneously, one for TX and the other for
RX. Is this possible?
Running the script usrp_benchmark_usb.py failed with two RFX2400 but
worked fine with one or none.
That's what i get:
Testing 2MB/sec... usb_contro
Hi everyone,
I am new to gnuradio, so this may be basic. Searching online, I couldn't
find a solution (other than advising to ditch the PC I am using :) )
I am running the usrp_siggen.py script to generate a sin wave using the
2.4GHz board and I get the following error when running the script:
I put the DBSRX modification instructions up at:

Hi All,
and thank you All for your Answers in my last thread.
Now i want to know, how i can convert the showing
values in the Y-Axis of the FFT-Plot Sink to dB, so that
i can interpret this correctly.
Do i have to define the max and min input value first ?
Results an input voltage 3.3V in the m

Hi Alberto
I have designed a simple frontend with a bandpass filter in several versions of
which one for 3 to 8 MHz using a MAR-4 for amplifier doing about 15 to 20db
gain.
See http://www.gnuradio.nl/pascal/BasicHFfront.html
You welcome to contact me if you are interested.
