Hi,
Try this:
./benchmark_tx.py -f 2.45G -r 512k --from-file=Apress.pdf
I think this will be work.

The USRP2 FPGA image can now be built with ISE 12.x. ISE 11.x probably
also works, but since 12 is a free upgrade from 11, I suggest you use
12. Everything still works on ISE 10.1.03 as well.
One additional change is that both the plain (Raw Ethernet) and UDP
versions (for UHD) are in the
With the change in 'date' and using 'awk', I still got the python dyld
load error, which I tracked down to the SWIG libraries. Doing 'make
clean' there and then 'make' did the trick. !...@#$% fragile SWIG stuff.

Can you test Darwin's 'awk' for this?
the '$' line returns exactly '4' ... I guess that's good?

I'm interested in demodulating the simple PPM signal commonly used for
RC aircraft control in the 72 MHz band. While searching, I came across
a post to this list back in 2005 where Chuck Swiger linked to a page
that looked interesting, but the page isn't up and archive.org doesn't
go that deep.

H, OK. But this is a *single* BASIC_RX card. Is that still going
to work?

II puut 40dB of 50MHz-low-pass-filtered gain in front of the Basic_RX,
and now it's "rational". :-)

Sorry for the double post; strange internet goings-on down here.
Nothing has changed about my setup w/r.t. 'cut' or anything else.
'which cut' returns '/usr/bin/cut' which is supplied by Darwin.
'which date' returns '/bin/date' which is also Darwin -- this issue
has been around for a while no

Hi
I have implemented multi-antennas for receiving using grc dual source but
when i set the bitrate above 1M it start displaying "Uo Uo" which i guess is
indication of overflow and it doesn't receive anything also. I am using
usrp1 with rfx2400 daughter card. Kindly help me with my problem.
