I got UHD Source receiver with frequency sweeper, its working fine but i need
to read and actually process the data to make graph out of it without using
QT GUI, i try to open with hex editor but dont seem to understand the

Hi Christian,
Use command port in USRP source to control center frequency. I've build a
frequency sweeper that can change center frequency automatically using
message strobe and python block that connected to USRP command port.

Hi all,
I using gnuradio companion and I want to saving data automatically by file

into .dat. I need to record value of frequency, time and relative power
during program running. Do i need to edit generate python from grc to

Hi all,
I'm on reseaching receiver radio frequency using USRP B200. I want to sweep
center frequency in rx usrp over 45-870 MHz. I want it running just like
slider on QT and WX slider. Is it possible to make it running automatically?
Best Regards,
Sinta.
