If I change the sample rate from 500kHz to 12.5MHz I can repeatedly generate

Hello Nigel,
The Copy block is a useful block for enabling/disabling portions of flowgraphs.

Thanks Derek,
I never spotted the COPY block.

Hi All,
I have prepared a GRC Flowgraph with several tab pages using the QT Tab Widget.
Each tab page has different displays such as spectrograms, waterfalls etc.
Behind these tab screens I have separate processing blocks running to generate
the data to display, all in parallel.
I am wondering

I have rebuilt gr-uhd with the UHD_USRP_MULTI_USRP_COMMAND_TIME_API defined.
Have I done something stupid ?
Thanks,

If this is your message, it will set the frequency to 1 GHz at time 100.1.

Hi,
All of a sudden, I seem to have a problem accessing any OOT Blocks.
Although the OOT Blocks compile and install fine. When I run GRC I get the
error:
AttributeError:'module' object has no attribute 'block...'
I have performed in python:
Import blockname
Blockname.__file__
Hi,
Anyone know or managed to implement the time command using a message port to
the UHD Source Block ?
I believe time commands are not implemented in the latest GNURadio gr-uhd ? Is
that correct ?
Thanks,
Nigel

Hi Marcus,
I have now tried exactly that and it works. Thanks. One thing I am trying now
is to implement the command times over the message ports but if you say time
commands are not supported in gr-uhd I maybe stuck. I see the functions are in
a ifdef.
Thanks,
Nigel

Hi All,
I am currently trying to compare any difference between the QT Time Sink and
the QT Vector Sink code. I have a GRC Flowgraph which uses both of these plots.
The QT Time Sink works every time, but if I connect a QT Vector Sink at the
same point it fails to display data other than zero, a
Hi,
Can anyone help point me in the right direction for implementing a dynamic
variable as a parameter within my own OOT module. For example, the same way UHD
Source RF Frequency parameter works which you can then adjust at runtime.

Hi,
Can anyone help me set the maximum output number of items within the C Code of
a GNU Radio OOT block ? I am trying to set this to a single sample as its a
decimating block and I need the next block to retune at specific sample times
whilst controlling the scheduler to limit the size of data
