Colleagues,
After some struggles, we are running USRP2.
Thank you very much for information and help
form the wiki page and the mailing list.
Next I would like to use time stamp data from
USRP2. It is necessary for our project of
making a radar receiver.
Would you please suggest me how we ca
Hi Matt,
I have some questions (prepared from a while before you have been submitted
USRP2 schematics so excuse me if some of them can be answered from your
schematics).
1) How USRP2 boots? and how the FPGA firmware is loaded?
2) What is USRP2 ADC chip? Is there an auxiliary ADC?
3) What is U

Hi friends,
Can anyone tell me how durable the USRPs are? Can I put them ON for hours
without worrying about damaging them in the process. I observed that the
daughter boards heat up after a while though not to a very high temperature.
I feel unplugging them frequently is a little unpleasant to me

The 250 MHz spec on the BasicTX is somewhat misleading.
Although the analog portion (basically the transformer)
is rated to that, the D/A converter is only running at
128 Megasamples/sec. Nyquist says I can only use that

BasicTX allow transmit only up to 44MHz, isn't it ?

The project I'm working on (an SDR for a spacecraft
communication groundstation) needs to transmit VHF at
around 145 MHz. There seems to be a distinct "gap"
in the transmit capabilities of the USRP daughterboards
between 32 MHz and 400 MHz.
I'm looking for suggestions as to how to best accomplis
Hey all,
I am using two XCVR2450 transceivers(one as transmitter and one as
receiver). When I use only the receiver using usrp_fft.py -RB , i see the
environment noise level is -50dB. when I use $usrp_siggen.py -TA -f2.45e9 as
transmitter in one shell script and $usrp.py -RB -f2.45e9 as receiver i
Hi Vaibhav,
You may have a look at this :
f = open('file', 'a')
f.write('%X\t' % (data))
I didn't try but it should be the way to print in hexadecimal and
appending to the file.

Hi all
I want to find a example file. fsk_rx.py and fsk_tx.py
But, I cannot found it in gnu radio3.1.3
gnuradio-example/python/usrp/fsk_r(t)x.py
Does any one know which gnu radio has this file.

Thanks I appreciate your reply. I think I have the same problem with
alliasing but my biggest problem is the gain control. I haven't updated
to the current firmware version yet. I hope it will solve the problem.

Well, I've got the USRP & gnuradio working...to the point where hf_radio.py
doesn't crash, provides me a very low level of background noise, and not much
else. I had kind of hoped that I could pick up at least wwv with a three meter
hunk of wire connected to RX-A, but no luck. Of course, I had e
