Another question I'm afraid,
I've resolved, I think, my previous question about the module path. The
module rtlsdr does not exist on my system even though I have the rtlsdr
library installed. So, I presume that the module has to be created somehow.
Moving on, I'm trying to get multimode.py go

I got it recently running with the gnuradio 3.6 and a Noxon DAB stick.
I had to change the usb ID in librtlsdr.c line 205

Hi,
I did tried to generate using USRP_Source (with squarewave as option) &
USRP_Sink (complex_float) blocks. However unable to see the desired o/p (I
see sinewave is being generated). Pse advise if any additional settings to
be made.
Regds,

What exactly do you mean by "osmosdr" ?
There is a package called osmo-sdr which is for the Osmo SDR hardware.
You do not need that if you want to use RTL2832U-based dongles.

Also here's a link to a great paper containing a good analysis of how
all the HDL modules come together. Worth reading to get a head start
but you definitely will want to also look at the code in Xilinx ISE.
FYI you need the full version of ISE to program to the N210. FYI2 the

Hey Tom,
I thought i was replying to the list.(Apologies) I was thinking
about it on similar lines as you have. If the fllow graph is stopped by

put some more data but i tried over running the flowgraph for a time spa
I got a partial answer to my previously posted question :). When I pass the
complex baseband I & Q with a costas loop block, the output indeed looks
like a square wave.
Does it mean that external reference clock does not correct the
phase/carrier offset error? Does it only solve the timing error
It is well know that microwaves, bluetooth, cordless phones are the major
interference sources in 2.4Ghz.
But what devices (with non WiFi standards) are using 5Ghz band used by
802.11n devices?
Specifically for 5180-5350, 5745-5805Mhz.

I've been working on a front-end board suitable for GPS and other GNSS
systems. It might be of interest to the GNU Radio community.
Goals for the project:
- high-quality signals from all current and near-future GNSS systems
(GPS, Glonass, Galileo, Compass)
- wide bandwidth---provides three 50

I checked the US spectrum allocation chart, there are some devices like
radar and satellite communication in the 5GHz bands.
Based on the comment of Cisco,
"It is generally true that fewer devices currently operating at 5 GHz are
causing interference as compared to 2.4-GHz devices. But this will c
"O" = overrun (PC not keeping up with received data from usrp or audio
card)
"U" = underrun (PC not providing data quickly enough)
You can try to reduce the sampling rate or use a better powerful machine. :)

I'm sorry to have to ask more questions.
The "Simple FM receiver" by Marcus Leech would seem to be simple in name
only. I'm sure that I have followed the installation instructions to the
letter but I still end up with an error as follows:

Phil, I just got simple_fm_rcv working today.
I had to:
open up a terminal
cd to my radio flowdiagram directory - /home/jim/gnu_radio
svn co https://www.cgran.org/svn/projects/simple_fm_rcv
cd to the directory - in my case - /home/jim/gnu_radio/simple_fm_rcv
I`m running benchmark_tx.py .
In my thought, benchmark_tx has to use make_packet in

However, Although I inputted a print code for tracing in the middle of
make_packet codes , I could not see output on screen.
