Thanks Eric.sox will get me started but I would eventually like my application to be able to open wav files. Unfortunately the Python wave library limits the sample size to 16 bits - OK for USRP but not for HPSDR. I have a feature request in at python.org to expand it. I'm still struggling to get
I have a narrowband FM receiver running (not based on GNU radio) using the usrp library and the USRP hardware. I would be helpful if the USRP firmware could reduce the sample to 25 ksps from the current 250 ksps at the maximum decimation factor. I want to try run ning my FM receiver on a TI OSK
The guy in the cubicle next to me says that it is possible to talk to a USRP from inside a vmware player using my USB1.1 patch for the USRP library. It is to early to tell if you can do anything useful from vmware, but he did successfully run the tx and rx programs.
Hopefully, we can use this to
Hi Kyle,
Hi, I've finally got the minimal gnuradio working.
That's great!
The problem may be the outdated cygwin system.
The mirror I was using for cygwin setup is for some reason not up to date.
So even though I did a 'current' installation, many of modules were
outdated.
Today, I
All,
In using usrp_rx_cfile.py, I pull complex I and Q data off of the USRP. I
was wondering if this data is handled in any analog fashion in the mixed
signal processor, or if the data is only handled in the FPGA.
To be specific, I want to know if, when using the GNU Radio USRP functions

Hi, EricThanks~ setting the msq_limit to 0 solved my problem.But actually if you take a look my code, I am inserting the packets to the queue after calling fg.start()

Hi all,
I am new to gnuradio and I was wondering if you could help me out with
some of the questions I have:

Yes, if you expect to be able to e.g. send a CTS after only SIFS time
Hi
I am having trouble with transmiting from a Basic TX daughterboard
(it's the only one I have for the time being). I've tried connecting an
oscilloscope to the output while running siggen.py, but there is no
signal coming out. Also, I notice a continuous stream of 'usrp

For an input sequence of length N and a filter with L taps
the output sequence should have N + L-1 samples.
It seems that the GnuRadio implementation produces exactly N
samples, ie, it does not generate the L-1 tail samples.
I guess the reason is that there is no way of knowing
when the input
Hi Don,
The mirror I was using is *.aarnet.edu.au ( cannot recall exactly ) since I
am located in Australia.
But I just found this mirror has been removed from the cygwin mirror list.
However, my local pc must have a cache to memorize that mirror. That's why I
got outdated cygwin packages.
Now I
Sorry Don. I mistook you as the user who are experiencing the same problem.
Just realized you are the guy who helped. (one of the developer?)
Thanks a lot along the way.
Kyle

Hi Don,
I can be almost sure that the mirror I used is
http://mirror.aarnet.edu.au/pub/cygwin/
It is really outdated. e.g. the binutil version is 20050610-1 cygwin is
1.5.19-4 and python is 2.4.1-1.
Maybe you can try that mirror and see if u can reproduce the problems I met
before.

Hi,
I must be doing something really stupid. I'm trying to figure out how to
compile against the C++ libraries.
I copied test_usrp_standard_tx.cc, timestuff.h, and timestuff.c to a new
folder, then I compiled the application using
g++ test_usrp_standard_tx.cc timestuff.c -lusrp -Wall
have u added /usr/local/lib in your LD_LIBRARY_PATH environment variable?
cheers
kyle
