One possible reason is that your transmitted signal may have a wider
spectrum than you think due to the intermittent nature and or intermod.
You should look at the spectrum of the output signal and make sure you are
not transmitting wider than you think. Rapid on-off keying of the
transmitted sig
Hi Marcus,
Thanks for your answer. I do expect some of the Tx power to leak into
my Rx chain, and my application can live with that. What I don't
understand, is why this power is much higher when transmitting packets
than when transmitting a continuous tone.

Just different spectra

Dear List,
I am using a USRP-2 with a WBX daughterboard that is operating in full
duplex mode. Both the Tx and Rx gain are cranked up to their maximum
values (tx gain 25 dB, rx gain 30 dB). The Tx and Rx frequencies are
about 70 MHz apart (Tx->964 MHz and Rx->892MHz). I'm having a little

This is vaguely similar to what happens under OpenBSD - PortAudio is
installed and working with other applications but Gnuradio doesn't
find it. I think your detection method needs work,

Hi list,
I am using a USRP1 with UHD directly in C++, and several times I got the
following error within a few seconds after starting my application:
UHD Error:
The receive packet handler caught an exception.
