We are about to connect the USRP with LFRX and LFTX daughter boards to
a laboratory data acquisition system where noise and ground loops are
an issue. Can anyone confirm my understanding of the grounding on the
USRP, daughter boards, and enclosure?
As I understand it, the USRP is floating with
Hi,
I recieved the same error at my relay node too and it was for the first
time.

Hello,
I am making good progress.
The first couple of weeks or so (months?) I was collecting information.
I managed to get some design articles about Mode S transponders,
various protocol specifications, and comments. I was able to decode
some packets by sight using the oscilloscope program. T

Hi List,
I'm writing a little script to collect some data with mine USRP/DSBRX
combo.
I receive this error:
Exception exceptions.ReferenceError: 'weakly-referenced object no longer
exists' in > ignored
Any suggestion?

hello all,
I am thinking about building loop antenna for 3-6 MHz to
receive some DRM stations. As I understand it the loop antenna is parallel
resonant circuit so without any amplifier the parallel res. circuit should
look into big impedance(~1 MOhm) to get high Q. Lfrx has 50 Ohm i
