Hi List,
just wanted to let you guys know that I created a PKGBUILD to create a gnuradio
package with the current git version, since the old svn one was out of date.
It's available via:
http://aur.archlinux.org/packages.php?ID=39425
I'd like to add this to the wiki, too.
Best regards,
Moritz

Thank you very much Josh

Did you mean the tune frequency in the basic R

Did you mean the tune frequency in the basic Rx same with the frequency that i
can set in the usrp source block ?
So if the same i set the frequency in the usrp source block(from my understand
is nco frequency ) equal 1.5Mhz
and the tones of the FFT sink seem like the product of the multipl
Hello,
I have once post this message. Please help me cause its very urgent.
I now have a project with the following specifications:
I need to send 2 input-signals parallel over USRP, then find out the
zero-crossings (time) of each signal so I can calculate the phase difference
of them.
The 1st
Thank you so much again Josh
So Josh could you give me some opinion
That
if my input signal pass through the USRP is about cos(wt+phi) after it
passed through the mixer by NCO that generate sinwt and coswt and met
with the cic filter inside the usrp
what my professor expect is
the output t
This seems to be cumbersome :(
Anyway, It may be easier to drop packets rather than samples, ,let's say I
want to drop 9 packets from each ten and only make use of one! Do you think
this is really easier??

In a word, NEVER. No self respecting communication systems designer
would allow that much excess bandwidth on the air or any realistic
transmission medium.
Typically 2-3 samples per baud is more than enough. You then use a
polyphase filter bank based clock recovery tool to FIND the correct

Ahh...I had tried power-cycling previously, without success, but
hadn't tried re-seating the RFX2400. Upon re-seating, I am now able
to get the RFX2400 to be properly recogni
Does anybody know if i want to set 2 channel of the usrp source in GRC how do i
do
for python example
self.u = usrp.source_c(0, nchan=2)
Thank you very much for every advice

Hi Josh
Great, thanks.
Allow me to add a follow up question.
Say that I want to interface the USRP1 to Simulink using the UHD and
supporting timed TX samples. Would that be feasible with the anticipated
state of the USRP1 support?
Kind Regards
Jesper Kristensen

The USRP1 does not feature timed samples, and simulink support is really
up to the folks at simulink inc, unless you want to

Generally when there's no response, it's an indication that the way
you asked your questions failed to attract the attention of people who could
help.

hi,
I just received an usrp2 board with a LFRX db. I installed the s/w from the
repository and tried connecting using the instructions. At startup, I see
all 6 led's flash and then d,f remain on. The ethernet led is flashing
orange some times when connected to 100MBPs ethernet port but never flashe

Roughly 0dBm would be a safe bet.
Which translates to roughly 0.22V
There are several handy places on the web for doing conversions between
dBm and voltage:

Hi All,
We have been using the USRP1 with the WBX card on it to communicate with
the AO-51 satellite. We are expecting to hear from the satellite using
an Fm Receiver GRC at 435.300 MHz but don't receive anything as yet, we
are pretty sure about our
