Hi Zing Yu,
to be fair, this problem is not what you asked for in your initial post.
A couple of notes:
- The output buffer does not have to be full in order for the scheduler
to call the following downstream block.
- Undeterministic latency is one inherent problem of GNU Radio
- 200 ms seems
I have now split the above flowgraph into two separate flowgraphs as following:
uhd usrp source - LPF - my custom block_1
my custom block 2 - uhd usrp sink
where I have divided the functionality of my original custom block into custom
block 1 and custom block 2.
Now, when I relay the information
Hi everyone,
I just wanted to announce that I've pushed ControlPort onto the next branch
(for more details on ControlPort, see this for now:
http://www.trondeau.com/home/2012/11/18/public-release-of-controlport.html).
A couple of notes. First, we've integrated ControlPort into gnuradio-core
so

The RFX900 doesn't have analog TX gain setting -- you have to use the
baseband magnitude exclusively to control RF output gain.
Try dropping the amplitude to

Hello all,
I have a question applying to everybody that have tried transmitting
symbols in different kinds of modulation (BPSK, QPSK, GMSK etc).
I am using the following configuration in GNU Radio ( random source block
- bytes to symbols - SRRC block - file sink)
The attached figure plots the
Have you taken into account the group delay of the filter? How long is
your filter? Try sending zeroes at the end to flush your filter state?

The filter is consisted of 55 taps.
I tried by sending zeros. Though zeros are interpreted in -1's from the
modulation mapping block.
Moreover, the zeros will be taken into account as symbols to be shaped,
therefore, the same thing will happen.

You'll need to figure out how to flush the filter state and send actual
0+0j samples through. Maybe you can set a flag and multiply the samples
coming out by 1 or 0 depending if you are flushing or not?

I think this means creating a new block as I cannot come up with a quick
way of implementing the above.
In any case, thanks much.
