Yeah, that's the problem, thanks. The work
And of course, you can always put a GRC wrapper around your custom block...

If you're somewhat familiar with how to write/modify blocks, it probably
wouldn't be difficult to implement that functionality by making a new block
that is a copy of gr_multiply_const_vcc.cc (for instance) and changing the work
function to do what you want.

Here's a vector-subtract grap
Yes, I can do my own blocks. It would be pretty trivial to do it
there. I just wanted to know if there was an easy way to do it
solely using GRC.

I did a hand-contrived case with a simple 16-element vector, and it

Hmm... I'm not sure about that. Seems reasonable to assume that the

Mostly I'd just be worried about the first or last subtraction - you might only
get a length 1023 vector out at the end.
When you link it up, can y
Will that preserve the absolute positions of the original vector
elements? The initial vector represents an FFT, so it's
important to me that I keep the same positions.

I would probably try converting the vector to a stream, delay the stream by 1
sample, subtract one stream from the other, and then convert the resulting
(difference) stream back to a vector.

I have a vector quantity (size 1024), and I want to do a calculation
on it such that v_out[i] = v_in[i] - v_in[i-1]
Is such a calculation possible in GRC? I haven't found any way to
get a hold of the individual elements of a vector.

Ok, I glanced at your code quickly, here are my thoughts (some of which you may
already do in files I haven't seen):
1) You are using tx_io[15] as a potentially highspeed I/O. This signal travels
via the radio daughter cards and could easily lead to EMI noise issues. You
could consider multiple

I'm not sure. That's a question for the organizers. If there is a recording
of it, I'll be sure to let everyone know.

Hey everyone,
I just wanted to let everyone know that I will be speaking at the new
Software Radio Implementation Forum's (SRIF) first workshop this January.
It's in Hong Kong, but registration is free for people in that part of the
world. You can find more details about it here:

It would probably be helpful if we could confirm that someone else
with the same setup sees the same issue.
What versions of of the WX libraries and development packages do you
have installed? What checkout of GNU Radio do you have? What about
the relevant Python packages?

I also like the structure change, and I think Michael's suggestion for
handling the migration is perfect.

Hi,
I have made some modifications to the existing burst tagger in the GNU Radio
source code.
It is now able to specify an amount of pre and post samples, which are
additionally tagged before and after the tag signal.
I have put my changes on my GitHub account, which is:
