Hi thanks for your comment. block2 is the gnuradio CMA equalizer block. I
want the CMA block to remain quiet when there is no signal of interest.

Bob,
Saw this the other day, but there isn't a lot to go on here. If block2
is your own, you can make it do the bypass. You can also use some
Try using a threshold off the mag squared and feed that into a
multiplier after block2 (with appropriate type adapters). As long as
block2 doesn't have a huge delay or do rate changes, this should work.

Simone,
you're asking a bit much of people who are essentially volunteers if
they need to install several modules before they can run and test your
code for you.
Obviously, SWIG isn't picking up the class you wrote. There can be
several reasons for this, maybe you forgot it in your SWIG
The machine that runs CGRAN down in some basement somewhere at Carnegie
Mellon has hit some issues again. Given that I'm no longer at the
university, these issues are becoming harder for me to address. At this
point, it's probably best for CGRAN to move on as we've all been in
discussion about

CGRAN is useful and I'd like to see it live on in some form, at least as a
directory of modules that people are developing. My gut feeling is that
github is a good way forward.
I'm not sure what kind of quality assertion you want to make by including
something in CGRAN (clueful developers? decent
Hi,
I have recorded with FCD pro+ and SRD# some IQ.wav files.
When I try to import them in Gnu Radio companion as a File source and
plot the frequency spectrum with the FFt sink I get nothing.
Are the IQ.wav files produced by the SDR# recognizable from the Gnu radio?
Thanks!
I'm trying to become familiar with gnuradio, starting with grc, but I've
run into a couple of stumbling blocks.
I'm using a USRP1 with an assortment of daughter boards, including LF-HF
and VHF capabilities. I'd like to be able to sample the spectrum in
relatively small segments, and capture the
Make sure you have a throttle block between the source and the FFT, set
to the rate at which you captured the wav. Also, there is a Wav File
Source under Audio. The plain File Source will also work (usually WAV is
16-bit signed, 2 chan), but will have a little noise at the beginning
(the wav

It will probably take a bunch of experimentation to find something that
works. Since you're probably interested in the very beginning of the
signal, you'll need to do power detection in parallel with a delayed
version of the signal so you trigger in time. Look up some of the
following
You need an ishort-to-complex block after the file source. The file
source does not convert for you. If that doesn't work and your data is
definitely good (and not too short), then no idea.
Please send replies to the list.

This is something that comes up at our dev calls (and other dev

George, if the support burden is getting to much, we can surely fix a

Thanks for the pointers. I'll try these some time this week... hopefully
before we see more lightning (Wed/Thurs). I do appreciate the help.

I agree with Martin that once we go to git, every project has its own
