Oh, I see. I was surprised of increasing the API's major version to 3,
but images are in 2.

Hi
I used XCVR2450 daughterboard for TX and RX on USRP2 and everything is fine.
Recently I began to use RFX2400 and DBSRX-LF, which I found out the
performance are much worse than XCVR2450.
Observed from FFT plot, I found out there are some weird spectrum response

Hi everyone.
I'm continuing my quest to try out my new USRP N210 and WBX transceiver
board. I still haven't managed to make it do anything useful yet.
I have it attached directly to a Mac OS X 10.6 system, via the built-in
gigabit ethernet interface. I updated N210 to the latest firmware

Hi,
The N210 we had was returning ping requests after we managed to burn the
latest firmware and fpga images on to it from
http://www.ettus.com/downloads/uhd_images/UHD-images-most-recent/. At that
point the green light on the ethernet port on the N210 was ON and the orange
light was blinking.

Dear all,
I'm trying to feed the received signal from USRP to a low-pass filter and sink
the filtered signal into a data file.
The received signal is in complex format. The receiver is built as:
u = usrp.source_c(0)
coeffs = gr.firdes.low_pass(1.0, 500e3, 20e3,.5e3,gr.firdes.WIN_HAMMING)

Hi,
I'm trying to load the firmware and fpga image onto N210.
I downloaded the latest image file from

And, I'm right now using usrp_n2xx_fw.bin for firmware and usrp_n210_fpga.bin
for fpga image.

Sorry for the delayed response to this, but I just tested out the
howto write a block code and had the same problem. I "fixed" the code,
but according to Eric's logs from December when he made these changes,
I'm not sure what's happening is what is supposed to be happening
after they did some work
I posted one question in an early email, but it might be better to put
it together with other questions here. I'd greatly appreciate your answers.
(1) When transmitting UHD packets (with USRP2 + WBX), after each
transmission, there is either one or a few "U" printed out. What does
"U" mean?

This book doesn't cover GNU Radio or the USRP, but I'm a big fan of it

Yes. One of the reasons for tying the call to the IRC
Could you post meeting minutes or a summary of some kind? I am very
interested in any new features in 3.4, and I am sure most others on this
list are as well.

Any people know the implementation of the generating python code in GRC? What
is the rule for generating python code from GRC file?
Any body can provide the detail document for me in explaining the
implementation detail in this code generation function?
Thanks a lot!

Josh,
Thanks very much.
When I use UHD transmitting packets, after each packet, there is a "U"
printed out. Would you tell me what "U" means?
In early GNU Radio versions, "U" means CPU underrun--GNU Radio not
sending data fast enough to a sink, either a USRP or an audio. But UHD

thank you very much for answering to my questions. It's good to know that
