Hi,
Considering we can get timesamples of rx samples from UHD in
metadata,can I add timesamples to tx samples,which would be send together.
Thanks.
Sure thing!

Hi list,
I'm writing a custom null sync block called "file_writer". What I want to do
is dump (to file or screen) what my null sync is receiving).
The problem is that if I use the file_writer in a flow graph, after the
"work" function is executed a few times it starts to receive the same input

Try again. I just checked and everything appears to be working
normally. M
Thanks martin for your explanation. I modified the dbpsk_loopback.grc
example to where my input sampling frequency is 16khz and instead of
looping back i'm using a uhd sink block with a sampling rate of 256khz.
Looking at the constellation on my spectrum analyzer i'm getting a dbpsk

Hi,
you're right. Using "return len(in0)" solve my problem.
Thanks

Hi list..
I'm implementing a FHSS and i have some trouble detecting my carriers, i
was triying to use the example usrp_spectrum_sense.py to see how they do it
but i'm still in the same trouble, does anyone knows a good reference or
have an explanation about how the detect the level of interference
Hi everyone,
I need to implement a mechanism that splits the span when is bigger than the
USRP limit. While I was looking for an example I found
"usrp_spectrum_sense.py". This script is old, so I want to know if there is an
updated way of spliting the span, or if I can rely in this example.

For anyone expecting answers from me about build-gnuradio and other of my apps
over the next few days, I'll be out of the loop.
My father is gravely ill and I'm busy making arrangements.

Hi everyone,
There is a new version of usrp_spectrum_sense.py that works with UHD instead of
USRP?
Thanks for your attention :)

Maybe my last replay is ambiguous.In metadata,the the time value of
rx_sample tags was get by the command "time.time()".Does it mean that
the actual time recorded in tags refer to when the sample goes through
AD in USRP with the clock in USRP?

Hi,
I found the following notes in file metadata.hpp in UHD:
/*!
* RX metadata structure for describing sent IF data.
* Includes time specification, fragmentation flags, burst flags,
and error codes.
* The receive routines will convert IF data headers into metadata.
*/
