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.

Do i have to define the max and min input value first ?

Community,
I've read all the faq and a lot of code (some codes i couldn't
understand, I learning c++ and verilog yet...) about USRP2, but I
also have doubts.
They are,
1 - Is the DUC fully implemented in FPGA?
2 - Is the complex modulation function[page 38, AD9777 datasheet] used?
3- The

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
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:

This is fine.

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

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

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.

Hi all,
Because of the tight budget, I only have one GSM phone, one RFX900 daughter

Is it possible to play with the OpenBTS with one RFX900 daughter card instead
of two?
