Excellent! Glad to hear it worked so well. One other thing to suggest,
in case you haven't done so already. Volk has a profiler tool,
volk_profile, which will tun

I have worked with the LimeSDR on 3.7, but not on 3.8. According to
github, work is still in progress to port LimeSuite to 3.8

Going back to this problem, I recently set up a fresh Raspberry Pi 4
system using Ubuntu Server 19.10 and compiled GNU Radio v3.7.13.5 from
source, which also compiled the built in Volk. I then ran volk_profile
and was surprised to find that the generic machine was very often
faster than NEON, and
Hi Glen,
In the top right corner of the flow you will see the flow properties box.
In there you can disable the GUI. You can then run your python file
directly, or even call the created class object from another file (have a
look inside the main function to see how the flow is instantiated). You c
My understanding is that you don't need to mess with the volk_config
file - the library will automatically read this file to determine
under-the-hood which machines to use to execute your function.

Hello all,
I'm working on a project that involves selecting and filtering 10-15
narrow channels (10kHz bandwidth) from a relatively broadband input
(1Mhz). I've been working on trying to implement this as performant as
possible using GNURadio companion (see this email thread

It is yes.

Hello all,
I'm working on an SDR project where I need to transmit a narrow
baseband signal on multiple different carriers simultaneously, over a
relatively wide bandwidth (1Mhz). Essentially, when working normally,
the system acts as a radio passthrough, retransmitting the existing
channels, but t
