Hello,
Is there anyone seeing message like
Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
when calling any GUI window?
I'm wondering that this message is caused by Ubuntu 11, or by GR 3.5.x
before I got this message, I've used Ubuntu 10 and GR 3.4.x
and I upgraded both OS
There are various kind of USRP series, USRP1, USRP2, E100, B100, and N200.
At a glance I could find some differences between them.
1. USB connection and Ethernet connection which determines the data rate
between the USRP and a PC.
(and it also makes difference when addressing USRP in GNU Radio.)

I noticed dramatic changes in the 3.5.0 release in the generation of the
constellation points of digital modulations. So, if the easy part is to
again modify the source code to match my needs, i need some help in

For the record, I was testing on this:

Slackware 13.37.0

In a less mathematical and more qualitative explanation, consider that
at any point in time, one bit of your signal is spread out over a wide
frequency spectrum. If you think of adding up all of the measurements
of little frequency bins across the whole spread spectrum, the noise
in each bin, bei

I thought this was the case; but as someone without any DSP experience this
boggles the mind... Do
Hi Kouki,
I don't think you will see the signal in an FFT window. GPS is spread
spectrum and the signal is below the noise floor. But the signal is
still decodable.

Thank you so much for your suggestions. I am wondering how to connect these
work class with other blocks in the flowgraph which have been built? In other
words, how to use them in flowgraph building?

Just to follow up, have you tried using the auto calibration of the IQ
channel released recently?
As far as we can discern, this might give you a good deal of reduction in
the problematic spurious frequencies.
Also by using manual tuning where the daughterboard tuning is at least 12.5

Song,
Every transmitted pkt has structure
preamble:access_code:header:payload_with_crc:'\x55'
header consists of 2 16-bit shorts, having payload length and whitener
offset.
On receiver side "framer sink" extracts the payload depending upon the
value of header (2 shorts).
