I have had no problems installing Gnu Radio under Kubuntu.
If you already have a potent machine, try that. It gives the added bonus of
being much prettier than Gnome ;)

I’ve builded a graph with a Complex cosine (8Ms/s of sample rate and 1 MHz of
frequency), the fractional interpolator with 12/8 value for interpolation and a
FFT sink with 12MS/s of sample rate. (throttle block included).

Uhm, so it’s a little bit confusing.
Another strange problem is that if i put a 0.64 value of interpolation, and my
flow graph is a file souce-fractional interpolator-file sink, and my source
file is 1GB of data, i’m expecting a 1GB*1/0.64 output filesize. But when i run
the graph i get a 800MB
Sorry, the filesize is my mistake. All okay now. Thank you.

Perhaps this is the wrong place to post this error, but I'm hoping for a quick

I'm getting a network unreachable error on an E100 when trying to run
benchmark_tx.py from the gnuradio next branch (Tom Rondeau?). Command line
error, and output of uhd_usrp_probe are attached.

Also in benchmark_tx.py I noticed that calling -m qpsk and -m bpsk still
default to their differential versions unless I explicitly use the
--non-differential switch. Was this intended? I assumed that specifying
*psk vs. d*psk would do the right thing.
Thanks,
Sean

Hi all,
I am facing Segmentation Fault error.

so just to be on the safe side, i'd really rather replace the fan.

Yes I have. I disconnected it. In my opinion, it is overkill for anything
going on in a USRP1.
YMMV,

Ah good, glad to hear it's not just me…
Do you run it with the top on or leave it open?
