My question pertains to modulation (transmission), not reception. :) I have
yet to find much of anything in the way of examples or a foundation of
doing this. Kind of surprised this seems to be an uncommon thing.
TL;DR: I would like to modulate an NTSC (analog) TV signal using GNURadio.

That's actually not surprising. The buffer is established when the
top_block is started and will be based on the size of the FFT you need
to run. Increasing the size of the filter will not increase the size
of the buffer. We'll have to figure out how we want the solution to
this to look. Mig

Quick note. If you're at DySPAN and are planning on coming, I'm going to
try and get us the hotel shuttle over to Clyde's. Meet me in the lobby
around 6:30.

Hi Ed - I'm glad to hear that GNU Radio 3.7.2.1 installed without issues using
MacPorts for you. 3.7.3 was released not long ago, and contains some nice fixes
-- especially for audio on OSX. You can

Hi Michael,
A short while ago, I installed 3.7.2.1 from your macports
implementation. The install went without trouble, and
I've been composing and running flowgraphs from GRC
with no issues.
I recently tried to port one of my custom blocks up to
the 3.7 api, and I encountered problems. In o
Hello,
Recently I had to use the Wifi implementation of the BBN 80211b.
The project is based on Gnuradio-3.1.1, and does not compile with 3.7.1.
I made some changes to compile with the new version, and now the
bn_80211b_test.py program works at least. I did not tested the other
modules which requ
Jawad,
I though I'd add a few more comments:

Much of the functionality of pre-cog has been ported to gr-mac, which works
with "core" features of gnuradio like the new message passing API. *We've
also added a burst_tagger block that converts length tags to tx_sob/tx_eob

Ok, thanks for the quick reply, this clarifies things for me.

Yes I am using only stock GNU Radio blocks.
I don't mind creating my own block for this, I just want to be sure that
there is no easier way that already exists say in GRC or through a python
wrapper (maybe using pmt).

Hi everyone,
I have several USRP N210 and I want all of them to transmit using the same
frequency. Since I cannot use FDMA (this is one of my requirements, not a
GNU Radio/USRP limitation) then I thought I would give TDMA a try.
I want to be able to tell a node not to transmit when it is not its
17 matches
