Hi all,
I have a flowgraph that reads a signal and writes its FFT samples to a
file. I need to run this continuously (for a long time), without running
out of memory.
I tired deleting the earlier FFT samples from the file but that messes up
with reading the data. I also tried starting writing to
tually being flushed. Rethinking the problem is likely

it. I need
this to be done real time and that's why I'm looking for the most efficient
way.

Hi all,
I have a GNU Radio flowgraph which uses a USRP to receive a signal,
converts it to log power FFT and then writes the result to a file, using
File Sink. I want to have a counter which increments with each FFT written
to the file.
Is there a way of maintaining and increasing count of the
Hi all,
I have a flowgraph that users a USRP to receive signal and writes it to a
file using a file sink.
I want to start writing to the file and a specific time precisely. I
modified the code to start running the flowgraph at a specific time but
booting up the USRP and setting up the flowgraph
Cool. I will try that.
Thank you very much :)

Hi Dan,
I have tried different gain values from 0 to 20.

Hi,
I have a USRP B200 set to transmit a signal (using uhd_tx_dpsk.grc in the
GNURadio examples) and another USRP B200 receive the signal (using
uhd_rx_dpsk.grc in the GNURadio examples). But the receiving USRP does not
receive the signal that is being transmitted by the other USRP, even though
Thank you very much for the information.

Hi all,
I have flowgraph that receives a signal from a USRP and converts it to log
power FFT and then writes the result to a file, using File Sink.
I want to understand how writing to the file works.
- If the signal is received for *n *seconds and it takes *m *seconds to
write to the
