Hi Alexander, I see exactly what is shown in the tutorial and I don't see any harmonics. There are a two "shoulders" left and right to the signal, which are caused by the window function, which is applied by the Frequency sink to reduce spectral leakage. When I increase the lower boundary of

Hi Alexander, that is obviously a "problem" in gnu radio ;) It depends on the window chosen and if it is normalized or not. The problem with the window functions in an FFT is, that you spread the power of the signal over multiple bins (which also happens when you have spectral leakage). You ca

Removing Python Bindings from 3.9 OOT

2022-03-30 Thread Brandon Smith
Hello, I am porting our GNURadio OOT from 3.8 to 3.9, and I have a block that we utilize only in C++ and do not expose in GRC/Python. What would be the correct method for removing it from the pybind process? I am hesitant to start removing it from the new bindings dir for fear of breaking the buil

As you have probably figured out by now, I don’t have experience with GRC. Your best answer will be to ask in the Matrix channel (or IRC if you are old-school). I’m guessing your question is related to the change in how the Python bindings are done? I think that was 3.9 and not 3.10… In the nex

Finding the GPS seconds time from GPSDO

2022-03-30 Thread isaac mario tupac davila
Hello I'm Isaac. As it is said in this web: https://files.ettus.com/manual/page_gpsdo.html , get_mboard_sensor("gps_time") gives us the seconds since January 1, 1970 (so UTC seconds). What I'm looking for is that GNU Radio gives me the GPS seconds directly (GPS time is ahead 18 seconds from UTC).

Conda package for gr-sdrplay3 OOT module for Windows

2022-03-30 Thread Franco VENTURI
Good news - with Ryan's help a few days ago I was able to create a recipe and a conda package for the gr-sdrplay3 OOT module for Windows. For those not familiar with it, the gr-sdrplay3 OOT module adds support for the SDRplay RSP devices as native GNU Radio sources, using directly the SDRplay A
