hello all
I am trying to create my own UHD block in gnu radio for this i use cc files
of already available module but i can't be able to do it. I have a basic
knowledge of OOT blocks and have able to create blocks using this
technique. can you please list the steps for this purpose.
Any help in t
Hello,
I'm not using GRC, it's an C++ application with no Python at all. That
is the flowgraph:
I've got one OsmoSource, to that are connected several paths like this:
freq xlating fir filter -> quadrature demod -> fir filter -> custom sink
And one path like:
freq xlating fir filter -> stream
Hello,
It all depends on your use case and potential for reuse, as well as if you are
using Gnuradio Companion. If you use GRC to layout and generate your flow
graphs, they will overwrite any custom code you add to the top_block.py.
Your understanding of the use of the null sink or zero source

Hello Blake,
can you explain what the advantage of using a hier block is? At the
moment I cannot see any advantage if I use this kind of block
combination only once.
I'm sorry, but I don't understand how a null sink alone helps me. If I
disconnect the path I've got an unconnected input, no unconn
Stefan,
Consider wrapping the blocks you want to switch in/out in a hier block.
Use the setter functions of the hier block parameters to:
1. lock the flow graph
2. swap in/out the null sink(s) [1]
3. unlock the flowgraph

Hi,
I'm working on this Linux SDR transceiver application (
http://qradiolink.org ) which is entirely based on Gnuradio. I use the
standard Alsa audio sink and source for analog transmission and
reception.
I've encountered the following problems: sometimes the audio has
delays of up to two second
Hello, all.
Following our presentation at the GRCon'17 [1], we're launching a
crowdfunding campaign for the XTRX SDR in the next week or so.
XTRX is a tiny miniPCIe embedded versatile SDR. Up to 120MSPS 2x2
MIMO; 10 MHz - 3.7 GHz Rx/Tx range; built-in GPSDO and much more.
