Marcus,
Thanks for the advice, this seems to do exactly what I'm looking for. My
only question is that I've been under the impression that the UHD doesn't
yet support GPIO for the B210. I did recently upgrade to 3.8.5 though so
maybe things have changed?

Jeon,
You can add an appropriate constant before the divide and compensate for
it afterward. The exact math will depend on the values coming out of the
correlators.

(That should be moving averages, not correlators). Also, subtracting
instead of dividing might do what you want.

I know this question has been asked before, several times, but I didn't

Thank you Jeff. Those are perfect.

Thanks Marcus I have tried building GNU Radio with Boost 1.49 (that required by
MATLAB)
I've made a little progress, but it's slow going. I got the header files (not
included with the MATLAB release) by downloading Boost 1.49, and building it
and installing it to a

I'm having some trouble getting my code to compile. I get the following

I tried this out and I'm having some problems. I'm on GR 3.7.8 and UHD
3.8.5, both the newest as far as I know.
What I did was make a flowgraph with a signal generator source and a UHD
sink in GRC. It works before I made any modifications. There are a few
lines in top_block.py that set the

My gut is telling me this is a swig problem. I don't know that it's frowned
upon, but it's not easy to read without some kind of highlighting that we'd
get from github or a gist with files. If I'm correct we'd also need to see
swig/ACK.i (probably missing an include and/or gr swig block magic.
Thank you so much Ron! I will try with the new version then.

Let's think about the following auto/cross correlator:

I've placed `divide` because I need to normalize the correlation result.
If we place `null source`, or `constant source with value of zero` right
before the `pad source`, the simplified form of the correlator
Hi all,
I'm having trouble when trying to run a GRC flowchart with the No GUI option.
The thing is that even with the simplest flowchart I get the following error:
can only concatenate list (not str) to list. I've tried all the different
configurations in the Options block but I get always the
It's an issue in that particular version of GNU Radio. I see the same
thing here.
The good news is that the No GUI option works correctly in the latest
release (3.7.8).

Hi Devin,
You wanted to ramp up/down the external PA: Use the GPIO pins, and the
ATR registers [1] or timed commands issued over the message bus [2] to
change their state
