Every time you instantiate a usrp source or sink it checks to see if
it needs firmware and/or an fpga bitstream. The library code checks
two MD5 hashes that are stored in the FX2 ram, o

Hard to say, I believe I have done both. However, I haven't been able to

I am now seeing something like this one crop up, very annoying.
Basically, I'm running in RX mode for a while. I stop running. I may
unplug usrp, plug it in. Then:

Nice install guide. Thanks.
FYI, we don't require numarray, just Numeric.

Hi,
I am installing gnuradio on fedora core3 and am getting some errors with
python, I am able to test the USRP with ./test_usrp_standard_rx and
./test_usrp_standard_rx, but when I try to run ./burn-basic-eeprom I get this
error:
Traceback (most recent call last):
File "./burn-basic-eeprom",
I have a USRP sort of working on USB 1. I still need to test it some
more to see if it is useful. I'm trying to get it to talk to an
OMAP5912OSK board.

Wow. Please ignore me completely. I totally misread your question.

In terms of physical ports a USB hub would solve that issue. However,
there may be a bandwidth issue since you're still only able to receive
the equivalent of a single USB port.
I hope

Dear gnuradio community,
I have USRP hardware and related software all set up on my Dell laptop
with FC2. My reception of AM/FM stations is still very noisy despite
trying out with various antennas. The last I tried with amplified
antenna (10 db). Still looking for better solution...

I think the chart is misformatted, this seems to make more sense

TechnoConcepts' RF to digital converter is the first 5 GHz carrier
speed RF to digital converter capable of direct conversion of a 5 GHz
RF carrier, eliminating all analog IF circuits.
