The install page:
http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGR
currently mentions:
$ apt-get install gnuradio
Given that some people want latest code, it would be useful to have the
packages in jessie-backports and describe that on the wiki too. E.g.
$ apt-get instal
Hi,
Have someone know the IQ imbalance problem of the USRP N210?Or do you
have the official measurement data about the IQ imbalance problem of the
USRP?
Environment:USRP N210,sbx board

If you turn the FFT averaging up to maximum and wait a little while, the
carriers will stand out.

Yes, I think this is the same thing I am trying to do, but I am not getting

execution, I was getting null signals.
You can see my setup in the attached file. It's a rather simple version

If you want to see individual carriers, you have to use a high
resolution FFT. Here's a 262144 point FFT on a DVB-T2 OFDM signal with a
1K FFT (853 active carriers). The carriers are spaced about 9 kHz.
Stronger tones are pilots.

Hello sir
Thank you for your reply. Well, I am trying to do some additional operation
to the receiver side of the OFDM transceiver (rx_OFDM).
I am intending to detect a doppler shift in the received signal, for which
I am trying to do an FFT over symbols collected in 1 second.

Typically, you'd do 1 (I)FFT per OFDM symbol. I recommend having a look
at the tx_ofdm.grc and rx_ofdm.grc examples, which show a full flow graph.

Daniel,
thanks for editing the wiki! One thing (unrelated to the fact that this
is a page for hams) is that there's a lot of overlap with other pages.
The installation, for example, is covered elsewhere and I'm not sure why
you're specifically addressing Debian-jessie users.
Things go out of date
You can set the range by middle clicking (with the mouse wheel) and
setting the Int. min parameter. Try -120 to start with.

Thank you. The silent failure of trial missing was the issue.

Hi Ekko,
I'm not sure what you're doing, because you don't share any code.

Hi Tim,
The new (originally intended) API is more intuitive. After thinking
again - I can live with having to add three lines to my hierarchical
blocks. It's better than complicating something more important (like
GRC) to get backward compatibility.
It's good to have confirmation that there wer
I started editing the HamRadio wiki page with some of the feedback from
recent discussions:
http://gnuradio.org/redmine/projects/gnuradio/wiki/HamRadio
Can anybody see any flaws in the content or the structure I have used?
Can anybody think of examples to add to the links?
