Hello everyone
I have recently updated my Gnuradio.When I try to import audio block and uhd
block I get errors saying Import Error:no module called _audio_swig and
_uhd_swig found.I tried reinstall the whole gnuradio and its packets but
with no success.
I would like to what could be the reason fo

I have the same problem -- I'm going to be using a USRP2 outdoors in the shade
(not direct sunlight) for around six hours in Yuma, Arizona, where the daytime
temperatures are 100-110 degrees F now in July. Will the USRP2 be able to
operate under these high temperatures?

Hi everyone,
I just wrote a new post about our recent server upgrade

Hey Marcus..a nice thing...
I did some manipulation in your script and it worked.
first I omitted the function "firmware" .. saved it and then ran the script.
then I downloaded the images from
http://www.ettus.com/downloads/uhd_releases/master_images/ (the .tar file)
then I extracted it and copi
Let me know if some further settings I need to do .

Hi,
I have a few questions about the (analog) AGC on the AD8347 mixer chip on
the Flex900 daughterboard.
1. Given a signal received with some known power, is it possible to read the
programmed AGC gains (and thereby find the mixer's noise figure)?
2. Is it possible to lock these gain settings? If

Suppose that we didn't have a specially mapped memory. I believe the
scheduler could easily ensure that contiguous chunks of memory are
always passed into the work function with little overhead for both read
and for write.
Now, I bet there will be a slight problem when you have a block with

Thanks, Marcus, for your prompt and detailed response. If I understand you
correctly:
1. The best case noise figure of the RFX900 daughterboard is about 3-3.8 dB.
This occurs when the mixer amplifiers are set to their highest gain setting.
2. These gain settings can be fixed via software (via UHD)
