GNURadio Leaking memory during repeated simulations

Hi, I am using GNURadio to decode a large amount of 1024-sample complex vectors of different modulation schemes. Thus, I have a for loop which runs gr.top_block.run() at each iteration and uses a vector sink to collect the results. The issue is that as the simulation keeps going, each itertion

GNURadio with Python 3 for Windows

Hi, Currently, the windows precompiled GNUradio installers found here feature GNURadio 3.8, but only with Python 2.7. My questions are: 1. Is there a currently precompiled Windows version of GNURadio 3.8 w/ Python 3? 2. If there is

Custom constellation scheme

Hi, I am currently using `digital.generic_mod` with the included modulation scheme from https://www.gnuradio.org/doc/sphinx-3.7.1/digital/constellations.html

OTA Encoding/Decoding with Ettus SDR & GNURadio

Hi, I am trying to do over-the-air (OTA) encoding and decoding using GNURadio and an Ettus SDR. I used a basic flowgraph (shown at https://imgur.com/a/P846OSe) which I know can correctly decode the encoded signal w/ 0 BER in simulation (w/o/ the SDR blocks). However, using the SDR sink/source

Python OOT module not showing up in GRC

Hi, I have followed Section 3.2 in the tutorial https://wiki.gnuradio.org/index.php/Guided_Tutorial_GNU_Radio_in_Python to setup an OOT python block in GRC. I followed the instructions on a Linux machine running GNURadio 3.7 and it worked exactly as described. I then ran the tutorial on an
