My advice is to get this all figured out in software before using any
hardware (usrps and spectrum analyzers).
You can simulate the effect of changing the max deviation all in
software using a noise source, throttle, nbfm tx block, and an fft sink
(all in grc).
I guarantee that changing max

Yes; see < http://gnuradio.org/cgit/gnuradio.git/commit/?id=acdf13612f55c3a4abd4f2f05d759a4
I want to design a FM radio with freq deviation can be change.
Then I tried to modified an example in GNUradio example folder which name
"fm_tx4.py" in line61,let max_dev=5 to 50K,shown in following yellow label.
but there is no change at all in a spectrum analyzer.
Help me,thanks

Hello,
I do IQ plotting for DBPSK, DQPSK, 8PSK. (Please have a look below):
For DBPSK:

For QPSK:
http://omploader.org/vMm16Zw/dqpsk_IQ_plotting.png
Can someone explain why for DQPSK positions of ideal points are wrong? It
should be [1,1], [-1,1
I am wondering if anyone in receipt of this note is friends with or
knows the name of a good high level contact at the ACLU. I have a
first amendment case I would like to discuss with them.
Please contact me OFF LIST.

I just want to do a demo about two radios in one USRP by time divition, both
are FM&FH, but with the intention to distingrish these radios,the FM
deviation and FH hop step should be different.Now I could control the hop
step,but the FM deviation can't be controled(FM deviation should be12.5K and

If you installed via Synaptic you likely just installed the binary
(i.e. pre-built) packages, which include the header files (necessary
for building your own, custom blocks), libraries, and the
applications/examples that come with GNURadio.
If you want to modify the existing examples, you'll need

I built gnuradio using Synaptic and it seems to be operational. I can change
python and also change and compile C++ code for some UCLA Zigbee packet
processing code just fine too. Where should the C++ source code for the
gnuradio routines themselves (e.g. gr blah blah) be located? Reading a bit
