Hi all,I was simulating filtering.grc example from Digital Modulation Primer
using GNU Radio by Tom Rondeau. However during execution it gives following
error. Can anybody help it out.
Executing: "/home/ehsan/mygn/filtering.py"
Traceback (most recent call last): File "/home/ehsan/mygn/filtering.

This is the default
Try use different frequency for transmitter and receiver.

Hi
When I try to establish the duplex comunication between two USRPs, I found
that if I put the code A infront of code B, only the transmitter works, but
if I put code B infront of code A, only receiver works.
Could anyone tells me the reason?
Thanks a lot!
code A:
self.source = uhd_rece
Thanks Josh. It worked. Apparently, the gr_modtool.py is not including the
API in the header.

'master' also just built & tested for me without issue on Fedora 17. All

I just cleaned and rebuilt master and all tests pass for me on Ubuntu

Output of gnuradio-config-info shows that I am on master.

Why are you trying to transmit it using the benchmark scripts? Why not
tx_samples_from_file or something similar?

Thanks very much for your reply. I also searched online about the

the TX/RX antenna. So termina
The problem was bad LD_LIBRARY_PATH.
Can anybody explain:
why with LD_LIBRARY_PATH=/usr/bin:usr/local/lib64:usr/local/lib, GRC won't

But the SDR(software define radio)doesn't processes the input signal Fc

Just install 3.6.3, you should be fine.
Otherwise, manually browse through /usr/local and kill everything that
